Giving the opportunity to everybody to set up/run nodes is one of IOTA's priority. A minimum amount of resources is obviously required to prevent easy attacks, but we are making sure that being active part of the IOTA network can be possible without crazy investments.
we are building our solution in such a way that the protocol is fair and lightweight.

📷
Hans Moog [IF]어제 오후 11:24
IOTA is not "free to use" but it's - fee-less
you have tokens? you can send them around for free
📷
Hans Moog [IF]어제 오후 11:25
you have no tokens? you have to pay to use the network
📷
lekanovic어제 오후 11:25
I think it is a smart way to avoid the spamming network problem
📷
Hans Moog [IF]어제 오후 11:26
owning tokens is essentially like owning a share of the actual network
and the throughput it can process
📷
Hans Moog [IF]어제 오후 11:26****​
if you don't need all of that yourself, you can rent it out to people and earn money
📷
Hans Moog [IF]어제 오후 11:27
mana = tokens * time since you own them
simplified
📷
Hans Moog [IF]어제 오후 11:27
the longer you hold your tokens and the more you have, the more mana you have
but every now and then you have to move them to "realize" that mana
📷
lekanovic어제 오후 11:28
Is there any other project that is using a Mana solution to the network fee problem ?
📷
Hans Moog [IF]어제 오후 11:28
nah
the problem with current protocol is that they are leader based
📷
Hans Moog [IF]어제 오후 11:29
you need absolute consensus on who the current leaders are and what their influence in the network is
that's how blockchains works
📷
Hans Moog [IF]어제 오후 11:29
if two block producers produce 2 blocks at the same time, then you have to choose which one wins
and where everybody attaches their next block to
IOTA works differently and doesn't need to choose a single leader
we therefore have a much bigger flexibility of designing our sybil protection mechanisms
in a way, mana is also supposed to solve the problem of "rewarding" the infrastructure instead of the validators
in blockchain only the miners get all the money
running a node and even if it's one that is used by a lot of people will only cost
you won't get anything back
no fees, nothing
the miners get it all
📷
Hans Moog [IF]어제 오후 11:31
in IOTA, the node operators receive the mana
which gives them a share of the network throughput
📷
Hans Moog [IF]어제 오후 11:32
because in blockchain you need to decide whose txs become part of the blocks
and it's not really based on networking protocols like AIMD
📷
lekanovic어제 오후 11:33
And the more Mana your node have, the more trust your node has and you have more to say in the FPC, is that correct?
📷
Hans Moog [IF]어제 오후 11:33
yeah
a node that has processed a lot of txs of its users will have more mana than other nodes
and therefore a bigger say in deciding conflicts
its a direct measure of "trust" by its users
📷
lekanovic어제 오후 11:34
And choosing committee for dRNG would be done on L1 protocol level?
Everything regarding Mana will be L1 level, right?
📷
Hans Moog [IF]어제 오후 11:35
Yeah
Mana is layer1, but will also be used as weight in L2 solutions like smart contracts
📷
lekanovic어제 오후 11:35
And you are not dependant on using SC to implement this
📷
Hans Moog [IF]어제 오후 11:35
No, you don't need smart contracts
That's all the base layer
📷
Hans Moog [IF]어제 오후 11:37
'Time' actually takes into account things like decay
So it doesn't just increase forever
It's close to "Demurrage" in monetary theory
📷
lekanovic어제 오후 11:36
For projects to be able to connect to Polkadot or Cosmos, you need to get the state of the ledger.
Will it be possible to get the Tangle state?
If this would be possible, then I think it would be SUPER good for IOTA
📷
Hans Moog [IF]어제 오후 11:38
Yeah but polkadot is not connecting other dlts
Just inhouse stuff
📷
Hyperware어제 오후 11:39
Is there still a cap on mana so that the rich don't get richer?
📷
Hans Moog [IF]어제 오후 11:39
Yes mana is capped
📷
TangleAccountant어제 오후 11:39
u/Hans Moog [IF] My first thought is that the evolution of this renting system will lead to several big mana renting companies that pool together tons of token holders mana. That way businesses looking to rent mana just need to deal with a reliable mana renting company for years instead of a new individual every couple of months (because life happens and you don't know if that individual will need to sell their IOTAs due to personal reasons). Any thoughts on this?
📷
Hans Moog [IF]어제 오후 11:41
u/TangleAccountant yes that is likely - but also not a bad thing - token holders will have a place to get their monthly payout and the companies that want to use the tangle without having tokens have a place to pay
📷
TangleAccountant어제 오후 11:42
Oh I completely agree. That's really cool. I'll take a stab at creating one of those companies in the US.
📷
Hans Moog [IF]어제 오후 11:42
And everybody who wants to run a node themselves or has tokens and wants use the tangle for free can do so
But "leachers" that would want to use the network for free won't be able to do so
I mean ultimately there will always be "fees", as there is no "free lunch".
You have a certain amount of resources that a network can process and you have a certain demand.
And that will naturally result in fees based on supply / demand
what you can do however is to build a system where the actual users of that system that legitimately want to use it can do so for free,
just because they already "invest" enough by having tokens
or running infrastructure
they are already contributing to the well-being of the network through these two aspects alone
it would be stupid to ask those guys for additional fees
and mana essentially tries to be such a measure of honesty among the users
📷
Hyperware어제 오후 11:47
It's interesting from an investment perspective that having tokens/mana is like owning a portion of the network.
📷
Hans Moog [IF]어제 오후 11:48
Yeah, you are owning a certain % of the throughput and whatever the price will ultimately be to execute on this network - you will earn proportionally
but you have to keep in mind that we are trying to build the most efficient DLT that you could possibly ever build
📷
semibaron어제 오후 11:48
The whole mana (tokens) = share of network throuput sounds very much like EOS tbh
Just that EOS uses DPoS
📷
Hans Moog [IF]어제 오후 11:50
yeah i mean there is really not too many new things under the sun - you can just tweak a few things here and there, when it comes to distributing resources
DPoS is simply not very nice from a centralization aspect
📷
Hans Moog [IF]어제 오후 11:50
at least not the way EOS does it
delegating weights is 1 thing
but assuming that the weight will always be in a way that 21 "identities" run the whole network is bad
in the current world you see a centralization of power
but ultimately we want to build a future where the wealth is more evenly distributed
and the same goes for voting power
📷
Hans Moog [IF]어제 오후 11:52
blockchain needs leader selection
it only works with such a centralizing component
IOTA doesn't need that
it's delusional to say that IOTA wouldn't have any such centralization
but maybe we get better than just a handselected nodes 📷
📷
Phantom3D어제 오후 11:52
How would this affect a regular hodler without a node. Should i keep my tokens elsewere to generate mana and put the tokens to use?
📷
Hans Moog [IF]어제 오후 11:53
you can do whatever you want with your mana
just make an account at a node you regularly use and use it to build up a reputation with that node
to be able to use your funds for free
or run a node yourself
or rent it out to companies if you just hodl
📷
semibaron어제 오후 11:54
Will there be a build-in function into the node software / wallet to delegate ("sell") my mana?
📷
Hans Moog [IF]어제 오후 11:55
u/semibaron not from the start - that would happen on a 2nd layer
------------------------------------------------------------------------------------------------------------

Hyperware오늘 오전 4:21
The only thing I can really do, is believe that the IF have smart answers and are still building the best solutions they can for the sake of the vision
📷
dom오늘 오전 4:43
100% - which is why we're spending so much effort to communicate it more clearly now
we'll do an AMA on this topic very soon
📷
M [s2]오늘 오전 4:54
u/dom​ please accept my question for the AMA: will IOTA remain a permissionless system and if so, how?
📷
dom오늘 오전 4:57
of course it remains permissionless
📷
dom오늘 오전 5:20
what is permissioned about it?
is ETH or Bitcoin permissioned because you have to pay a transaction fee in their native token?
📷
Gerrit오늘 오전 5:24
How did your industry partners think about the mana solution and the fact they need to hold the token to ensure network throughput?
📷
dom오늘 오전 5:26
u/Gerrit considering how the infrastructure, legal and regulatory frameworks are improving around the adoption and usage of crypto-currencies within large companies, I really think that we are introducing this concept exactly at the right time. It should make enterprise partners comfortable in using the permissionless network without much of a hurdle. They can always launch their own network if they want to ...
📷
Gerrit오늘 오전 5:27
Launching their own network can’t be what you want
📷
dom오늘 오전 5:27
exactly
but that is what's happening with Ethereum and all the other networks
they don't hold Ether tokens either.
📷
Gerrit오늘 오전 5:32
Will be very exciting to see if ongoing regulation will „allow“ companies to invest and hold the tokens. With upcoming custody solutions that would be a fantastic play.
📷
Hans Moog [IF]오늘 오전 5:34
It's still possible to send transactions even without mana - mana is only used in times of congestion to give the people that have more mana more priority
there will still be sharding to keep the network free most of the time
📷
Hans Moog [IF]오늘 오전 5:35
but without a protection mechanism, somebody could just spam a lot of bullshit and you could break the network(수정됨)
you need some form of protection from this
📷
M [s2]오늘 오전 5:36
u/Hans Moog [IF] so when I have 0 Mana, I can still send transactions? This is actually the point where it got strange...
📷
Hans Moog [IF]오늘 오전 5:37
yes you can
unless the network is close to its processing capabilities / being attacked by spammers
then the nodes will favor the mana holders
📷
Hans Moog [IF]오늘 오전 5:37
but having mana is not a requirement for many years to come
currently even people having fpgas can't spam that many tps
and we will also have sharding implemented by then
📷
M [s2]오늘 오전 5:39
Thank you u/Hans Moog [IF] ! This is the actually important piece of info!
📷
Basha오늘 오전 5:38
ok, i thought it was communicated that you need at least 1 mana to process a transaction.
from the blogpost: "... a node with 0 mana can issue no transactions."
maybe they meant during the congestion**, but if that's the case maybe you should add that**
📷
Hans Moog [IF]오늘 오전 5:42
its under the point "Congestion control:"
yeah this only applies to spam attacks
network not overloaded = no mana needed
📷
Hans Moog [IF]오늘 오전 5:43
if congested => favor txs from people who have the most skin in the game
but sharding will try to keep the network non-congested most of the time - but there might be short periods of time where an attacker might bring the network close to its limits
and of course its going to take a while to add this, so we need a protection mechanism till sharding is supported(수정됨)
📷
Hans Moog [IF]오늘 오전 6:36
I don't have a particular problem with EOS or their amount of validators - the reason why I think blockchain is inferior has really nothing to do with the way you do sybil protection
and with validators I mean "voting nodes"
I mean even bitcoin has less mining pools
and you could compare mining pools to dpos in some sense
where people assign their weight (in that case hashing power) to the corresponding mining pools
so EOS is definitely not less decentralized than any other tech
but having more identities having weight in the decision process definitely makes it harder to corrupt a reasonable fraction of the system and makes it easier to shard
so its desirable to have this property(수정됨)

Disclaimer:
I'm sorry, maybe I'm fueling some confusion through posting this mana-thing too soon,
but, instead of erasing this posting, I'm adding recent convos.
Certain things about mana seem to be not clear, yet.
It would be better to wait for some official clarification.
But, I hope the community gives its full support to IF, 'cause
there could be always some bumps along the untouched, unchartered way.

It's still possible to send transactions even without mana - mana is only used in times of congestion to give the people that have more mana more priority
u/Hans Moog [IF] Im sorry Hans, but this is false in the current congestion control algorithm. No mana = no transactions. To be honest, we havent really tried to make it work so that you can sent transactions with no mana during ties with no congestion, but I dont see how you can enable this and still maintain the sybil protection required. u/Luigi Vigneri [IF] What do you think?📷

Ethereum 's Top 7 Mining Tools in 2020

If there is a cryptocurrency that has acquired popularity close to Bitcoin, then it is Ethereum. It is among the leading crypto-currencies when it comes to market capitalization. Ethereum is not just a cryptocurrency, but it is also a blockchain system that is useful in creating decentralised applications. Since Ethereum Blockchain is used by most companies now, it is gaining popularity among Ethereum miners and developers.
Ethereum mining is a great way to make more cash. Benefiting from cryptocurrencies in p is a perfect option. Since many applications for Blockchain depend on Ethereum. Ethereum mining is going to be lucrative, as its price is expected to grow. The Ethereum minimum can be simplified with the use of the best Ethereum software. There are some apps like that on the market, and we've got the seven best for you here.
7 Ethereum 's Best Apps:
ETHminer- This is an Ethereum mining application which is supported on Linux , Windows, and Mac. It is also possible to use the Ethash algorithm, luke Ellaisma, Musicoin Ethereum Classic, Metaverse, It is a command-line program that allows you to construct shortcut commands using a Windows cmd / batch file or Linux Bash script.
The next software on our list is CGMiner-A, which was published in 2011. It is one of the common choices and has compatibility with GPU, FPGA, and ASIC. It is open-source software and can cause advanced detection of blocks.
It is written in C; Ethereum developers are able to save a hash rate without delay using this Ethereum mining programme. On Linux , Windows, and Mac, this program is open.
BitMinter- The graphical interface is transparent and it links easily to the Bitminter mining pool. This software was launched in 2011 and has more than 450,000 user accounts registered. The Java Network Launch Protocol (JNLP) is the foundation of its operations. Linux, Windows and Mac are also compatible with this programme.
Claymore- This is one of the most powerful mining applications for Ethereum, and without delaying the mining pace, you can scale up the hash rate. You can also mine other cryptocurrencies like Lbry, Pascal, Siacoin, and Decred using this Ethereum mining programme. This software is Linux and Windows compatible and not Mac compatible.
WinETH- If you are looking for an Ethereum mining app that is fast and simple to use, then this is the one for you. It is comparable to WinETH, but it has a simpler Interface and a smarter algorithm that makes it easy to use for Ethereum miners.
Minergate-It was the first mining app for Ethereum to deliver merged mining. You can use this app to concurrently mine two separate coins without impacting the main coin's hash rate. In addition, this coin will also tell you about the market's most valuable coins.
This programme can be used by Ethereum miners to mine other coins, including Zcash, Liteoin, Monero.
BFGMiner- This programme is written in C and operates on various Linux, Windows and Mac operating systems. You will mine crypto coins and have both SHA256D and Scrypt on its algorithm. It also offers you total support for tracking.
Conclusion- These are some of the popular mining applications for Ethereum that you can use. If you would like to know more about the creation of Ethereum, or Ethereum mining, If you wish to know more about Ethereum development, or Ethereum mining, or you want to enroll for Ethereum certification, connect with Blockchain Council today.

Transcript of discussion between an ASIC designer and several proof-of-work designers from #monero-pow channel on Freenode this morning

[08:07:01] lukminer contains precompiled cn/r math sequences for some blocks: https://lukminer.org/2019/03/09/oh-kay-v4r-here-we-come/
[08:07:11] try that with RandomX :P
[08:09:00] tevador: are you ready for some RandomX feedback? it looks like the CNv4 is slowly stabilizing, hashrate comes down...
[08:09:07] how does it even make sense to precompile it?
[08:09:14] mine 1% faster for 2 minutes?
[08:09:35] naturally we think the entire asic-resistance strategy is doomed to fail :) but that's a high-level thing, who knows. people may think it's great.
[08:09:49] about RandomX: looks like the cache size was chosen to make it GPU-hard
[08:09:56] looking forward to more docs
[08:11:38] after initial skimming, I would think it's possible to make a 10x asic for RandomX. But at least for us, we will only make an ASIC if there is not a total ASIC hostility there in the first place. That's better for the secret miners then.
[08:13:12] What I propose is this: we are working on an Ethash ASIC right now, and once we have that working, we would invite tevador or whoever wants to come to HK/Shenzhen and we walk you guys through how we would make a RandomX ASIC. You can then process this input in any way you like. Something like that.
[08:13:49] unless asics (or other accelerators) re-emerge on XMR faster than expected, it looks like there is a little bit of time before RandomX rollout
[08:14:22] 10x in what measure? $/hash or watt/hash?
[08:14:46] watt/hash
[08:15:19] so you can make 10 times more efficient double precisio FPU?
[08:16:02] like I said let's try to be productive. You are having me here, let's work together!
[08:16:15] continue with RandomX, publish more docs. that's always helpful.
[08:16:37] I'm trying to understand how it's possible at all. Why AMD/Intel are so inefficient at running FP calculations?
[08:18:05] midipoet ([email protected]/web/irccloud.com/x-vszshqqxwybvtsjm) has joined #monero-pow
[08:18:17] hardware development works the other way round. We start with 1) math then 2) optimization priority 3) hw/sw boundary 4) IP selection 5) physical implementation
[08:22:32] This still doesn't explain at which point you get 10x
[08:23:07] Weren't you the ones claiming "We can accelerate ProgPoW by a factor of 3x to 8x." ? I find it hard to believe too.
[08:30:20] sure
[08:30:26] so my idea: first we finish our current chip
[08:30:35] from simulation to silicon :)
[08:30:40] we love this stuff... we do it anyway
[08:30:59] now we have a communication channel, and we don't call each other names immediately anymore: big progress!
[08:31:06] you know, we russians have a saying "it was smooth on paper, but they forgot about ravines"
[08:31:12] So I need a bit more details
[08:31:16] ha ha. good!
[08:31:31] that's why I want to avoid to just make claims
[08:31:34] let's work
[08:31:40] RandomX comes in Sep/Oct, right?
[08:31:45] Maybe
[08:32:20] We need to audit it first
[08:32:31] ok
[08:32:59] we don't make chips to prove sw devs that their assumptions about hardware are wrong. especially not if these guys then promptly hardfork and move to the next wrong assumption :)
[08:33:10] from the outside, this only means that hw & sw are devaluing each other
[08:33:24] neither of us should do this
[08:33:47] we are making chips that can hopefully accelerate more crypto ops in the future
[08:33:52] signing, verifying, proving, etc.
[08:34:02] PoW is just a feature like others
[08:34:18] sech1: is it easy for you to come to Hong Kong? (visa-wise)
[08:34:20] or difficult?
[08:34:33] or are you there sometimes?
[08:34:41] It's kind of far away
[08:35:13] we are looking forward to more RandomX docs. that's the first step.
[08:35:31] I want to avoid that we have some meme "Linzhi says they can accelerate XYZ by factor x" .... "ha ha ha"
[08:35:37] right? we don't want that :)
[08:35:39] doc is almost finished
[08:35:40] What docs do you need? It's described pretty good
[08:35:41] so I better say nothing now
[08:35:50] we focus on our Ethash chip
[08:36:05] then based on that, we are happy to walk interested people through the design and what else it can do
[08:36:22] that's a better approach from my view than making claims that are laughed away (rightfully so, because no silicon...)
[08:36:37] ethash ASIC is basically a glorified memory controller
[08:36:39] sech1: tevador said something more is coming (he just did it again)
[08:37:03] yes, some parts of RandomX are not described well
[08:37:10] like dataset access logic
[08:37:37] RandomX looks like progpow for CPU
[08:37:54] yes
[08:38:03] it is designed to reflect CPU
[08:38:34] so any ASIC for it = CPU in essence
[08:39:04] of course there are still some things in regular CPU that can be thrown away for RandomX
[08:40:20] uncore parts are not used, but those will use very little power
[08:40:37] except for memory controller
[08:41:09] I'm just surprised sometimes, ok? let me ask: have you designed or taped out an asic before? isn't it risky to make assumptions about things that are largely unknown?
[08:41:23] I would worry
[08:41:31] that I get something wrong...
[08:41:44] but I also worry like crazy that CNv4 will blow up, where you guys seem to be relaxed
[08:42:06] I didn't want to bring up anything RandomX because CNv4 is such a nailbiter... :)
[08:42:15] how do you guys know you don't have asics in a week or two?
[08:42:38] we don't have experience with ASIC design, but RandomX is simply designed to exactly fit CPU capabilities, which is the best you can do anyways
[08:43:09] similar as ProgPoW did with GPUs
[08:43:14] some people say they want to do asic-resistance only until the vast majority of coins has been issued
[08:43:21] that's at least reasonable
[08:43:43] yeah but progpow totally will not work as advertised :)
[08:44:08] yeah, I've seen that comment about progpow a few times already
[08:44:11] which is no surprise if you know it's just a random sales story to sell a few more GPUs
[08:44:13] RandomX is not permanent, we are expecting to switch to ASIC friendly in a few years if possible
[08:44:18] yes
[08:44:21] that makes sense
[08:44:40] linzhi-sonia: how so? will it break or will it be asic-able with decent performance gains?
[08:44:41] are you happy with CNv4 so far?
[08:45:10] ah, long story. progpow is a masterpiece of deception, let's not get into it here.
[08:45:21] if you know chip marketing it makes more sense
[08:45:24] linzhi-sonia: So far? lol! a bit early to tell, don't you think?
[08:45:35] the diff is coming down
[08:45:41] first few hours looked scary
[08:45:43] I remain skeptical: I only see ASICs being reasonable if they are already as ubiquitous as smartphones
[08:45:46] yes, so far so good
[08:46:01] we kbew the diff would not come down ubtil affter block 75
[08:46:10] yes
[08:46:22] but first few hours it looks like only 5% hashrate left
[08:46:27] looked
[08:46:29] now it's better
[08:46:51] the next worry is: when will "unexplainable" hashrate come back?
[08:47:00] you hope 2-3 months? more?
[08:47:05] so give it another couple of days. will probably overshoot to the downside, and then rise a bit as miners get updated and return
[08:47:22] 3 months minimum turnaround, yes
[08:47:28] nah
[08:47:36] don't underestimate asicmakers :)
[08:47:54] you guys don't get #1 priority on chip fabs
[08:47:56] 3 months = 90 days. do you know what is happening in those 90 days exactly? I'm pretty sure you don't. same thing as before.
[08:48:13] we don't do any secret chips btw
[08:48:21] 3 months assumes they had a complete design ready to go, and added the last minute change in 1 day
[08:48:24] do you know who is behind the hashrate that is now bricked?
[08:48:27] innosilicon?
[08:48:34] hyc: no no, and no. :)
[08:48:44] hyc: have you designed or taped out a chip before?
[08:48:51] yes, many years ago
[08:49:10] then you should know that 90 days is not a fixed number
[08:49:35] sure, but like I said, other makers have greater demand
[08:49:35] especially not if you can prepare, if you just have to modify something, or you have more programmability in the chip than some people assume
[08:50:07] we are chipmakers, we would never dare to do what you guys are doing with CNv4 :) but maybe that just means you are cooler!
[08:50:07] and yes, programmability makes some aspect of turnaround easier
[08:50:10] all fine
[08:50:10] I hope it works!
[08:50:28] do you know who is behind the hashrate that is now bricked?
[08:50:29] inno?
[08:50:41] we suspect so, but have no evidence
[08:50:44] maybe we can try to find them, but we cannot spend too much time on this
[08:50:53] it's probably not so much of a secret
[08:51:01] why should it be, right?
[08:51:10] devs want this cat-and-mouse game? devs get it...
[08:51:35] there was one leak saying it's innosilicon
[08:51:36] so you think 3 months, ok
[08:51:43] inno is cool
[08:51:46] good team
[08:51:49] IP design house
[08:51:54] in Wuhan
[08:52:06] they send their people to conferences with fake biz cards :)
[08:52:19] pretending to be other companies?
[08:52:26] sure
[08:52:28] ha ha
[08:52:39] so when we see them, we look at whatever card they carry and laugh :)
[08:52:52] they are perfectly suited for secret mining games
[08:52:59] they made at most $6 million in 2 months of mining, so I wonder if it was worth it
[08:53:10] yeah. no way to know
[08:53:15] but it's good that you calculate!
[08:53:24] this is all about cost/benefit
[08:53:25] then you also understand - imagine the value of XMR goes up 5x, 10x
[08:53:34] that whole "asic resistance" thing will come down like a house of cards
[08:53:41] I would imagine they sell immediately
[08:53:53] the investor may fully understand the risk
[08:53:57] the buyer
[08:54:13] it's not healthy, but that's another discussion
[08:54:23] so mid-June
[08:54:27] let's see
[08:54:49] I would be susprised if CNv4 ASICs show up at all
[08:54:56] surprised*
[08:54:56] why?
[08:55:05] is only an economic question
[08:55:12] yeah should be interesting. FPGAs will be near their limits as well
[08:55:16] unless XMR goes up a lot
[08:55:19] no, not *only*. it's also a technology question
[08:55:44] you believe CNv4 is "asic resistant"? which feature?
[08:55:53] it's not
[08:55:59] cnv4 = Rabdomx ?
[08:56:03] no
[08:56:07] cnv4=cryptinight/r
[08:56:11] ah
[08:56:18] CNv4 is the one we have now, I think
[08:56:21] since yesterday
[08:56:30] it's plenty enough resistant for current XMR price
[08:56:45] that may be, yes!
[08:56:55] I look at daily payouts. XMR = ca. 100k USD / day
[08:57:03] it can hold until October, but it's not asic resistant
[08:57:23] well, last 24h only 22,442 USD :)
[08:57:32] I think 80 h/s per watt ASICs are possible for CNv4
[08:57:38] linzhi-sonia where do you produce your chips? TSMC?
[08:57:44] I'm cruious how you would expect to build a randomX ASIC that outperforms ARM cores for efficiency, or Intel cores for raw speed
[08:57:48] curious
[08:58:01] yes, tsmc
[08:58:21] Our team did the world's first bitcoin asic, Avalon
[08:58:25] and upcoming 2nd gen Ryzens (64-core EPYC) will be a blast at RandomX
[08:58:28] designed and manufactured
[08:58:53] still being marketed?
[08:59:03] linzhi-sonia: do you understand what xmr wants to achieve, community-wise?
[08:59:14] Avalon? as part of Canaan Creative, yes I think so.
[08:59:25] there's not much interesting oing on in SHA256
[08:59:29] Inge-: I would think so, but please speak
[08:59:32] hyc: yes
[09:00:28] linzhi-sonia: i am curious to hear your thoughts. I am fairly new to this space myself...
[09:00:51] oh
[09:00:56] we are grandpas, and grandmas
[09:01:36] yet I have no problem understanding why ASICS are currently reviled.
[09:01:48] xmr's main differentiators to, let's say btc, are anonymity and fungibility
[09:01:58] I find the client terribly slow btw
[09:02:21] and I think the asic-forking since last may is wrong, doesn't create value and doesn't help with the project objectives
[09:02:25] which "the client" ?
[09:02:52] Monero GUI client maybe
[09:03:12] MacOS, yes
[09:03:28] What exactly is slow?
[09:03:30] linzhi-sonia: I run my own node, and use the CLI and Monerujo. Have not had issues.
[09:03:49] staying in sync
[09:03:49] linzhi-sonia: decentralization is also a key principle
[09:03:56] one that Bitcoin has failed to maintain
[09:04:39] hmm
[09:05:00] looks fairly decentralized to me. decentralization is the result of 3 goals imo: resilient, trustless, permissionless
[09:05:28] don't ask a hardware maker about physical decentralization. that's too ideological. we focus on logical decentralization.
[09:06:11] physical decentralization is important. with bulk of bitnoin mining centered on Chinese hydroelectric dams
[09:06:19] have you thought about including block data in the PoW?
[09:06:41] yes, of course.
[09:07:39] is that already in an algo?
[09:08:10] hyc: about "centered on chinese hydro" - what is your source? the best paper I know is this: https://coinshares.co.uk/wp-content/uploads/2018/11/Mining-Whitepaper-Final.pdf
[09:09:01] linzhi-sonia: do you mine on your ASICs before you sell them?
[09:09:13] besides testing of course
[09:09:45] that paper puts Chinese btc miners at 60% max
[09:10:05] tevador: I think everybody learned that that is not healthy long-term!
[09:10:16] because it gives the chipmaker a cost advantage over its own customers
[09:10:33] and cost advantage leads to centralization (physical and logical)
[09:10:51] you guys should know who finances progpow and why :)
[09:11:05] but let's not get into this, ha ha. want to keep the channel civilized. right OhGodAGirl ? :)
[09:11:34] tevador: so the answer is no! 100% and definitely no
[09:11:54] that "self-mining" disease was one of the problems we have now with asics, and their bad reputation (rightfully so)
[09:13:08] I plan to write a nice short 2-page paper or so on our chip design process. maybe it's interesting to some people here.
[09:13:15] basically the 5 steps I mentioned before, from math to physical
[09:13:32] linzhi-sonia: the paper you linked puts 48% of bitcoin mining in Sichuan. the total in China is much more than 60%
[09:13:38] need to run it by a few people to fix bugs, will post it here when published
[09:14:06] hyc: ok! I am just sharing the "best" document I know today. it definitely may be wrong and there may be a better one now.
[09:14:18] hyc: if you see some reports, please share
[09:14:51] hey I am really curious about this: where is a PoW algo that puts block data into the PoW?
[09:15:02] the previous paper I read is from here http://hackingdistributed.com/2018/01/15/decentralization-bitcoin-ethereum/
[09:15:38] hyc: you said that already exists? (block data in PoW)
[09:15:45] it would make verification harder
[09:15:49] linzhi-sonia: https://the-eye.eu/public/Books/campdivision.com/PDF/Computers%20General/Privacy/bitcoin/meh/hashimoto.pdf
[09:15:51] but for chips it would be interesting
[09:15:52] we discussed the possibility about a year ago https://www.reddit.com/Monero/comments/8bshrx/what_we_need_to_know_about_proof_of_work_pow/
[09:16:05] oh good links! thanks! need to read...
[09:16:06] I think that paper by dryja was original
[09:17:53] since we have a nice flow - second question I'm very curious about: has anyone thought about in-protocol rewards for other functions?
[09:18:55] we've discussed micropayments for wallets to use remote nodes
[09:18:55] you know there is a lot of work in other coins about STARK provers, zero-knowledge, etc. many of those things very compute intense, or need to be outsourced to a service (zether). For chipmakers, in-protocol rewards create an economic incentive to accelerate those things.
[09:19:50] whenever there is an in-protocol reward, you may get the power of ASICs doing something you actually want to happen
[09:19:52] it would be nice if there was some economic reward for running a fullnode, but no one has come up with much more than that afaik
[09:19:54] instead of fighting them off
[09:20:29] you need to use asics, not fight them. that's an obvious thing to say for an asicmaker...
[09:20:41] in-protocol rewards can be very powerful
[09:20:50] like I said before - unless the ASICs are so useful they're embedded in every smartphone, I dont see them being a positive for decentralization
[09:21:17] if they're a separate product, the average consumer is not going to buy them
[09:21:20] now I was talking about speedup of verifying, signing, proving, etc.
[09:21:23] they won't even know what they are
[09:22:07] if anybody wants to talk about or design in-protocol rewards, please come talk to us
[09:22:08] the average consumer also doesn't use general purpose hardware to secure blockchains either
[09:22:14] not just for PoW, in fact *NOT* for PoW
[09:22:32] it requires sw/hw co-design
[09:23:10] we are in long-term discussions/collaboration over this with Ethereum, Bitcoin Cash. just talk right now.
[09:23:16] this was recently published though suggesting more uptake though I guess https://btcmanager.com/college-students-are-the-second-biggest-miners-of-cryptocurrency/
[09:23:29] I find it pretty hard to believe their numbers
[09:24:03] well
[09:24:09] sorry, original article: https://www.pcmag.com/news/366952/college-kids-are-using-campus-electricity-to-mine-crypto
[09:24:11] just talk, no? rumors
[09:24:18] college students are already more educated than the average consumer
[09:24:29] we are not seeing many such customers anymore
[09:24:30] it's data from cisco monitoring network traffic
[09:24:33] and they're always looking for free money
[09:24:48] of course anyone with "free" electricity is inclined to do it
[09:24:57] but look at the rates, cannot make much money
[09:26:06] Ethereum is a bloated collection of bugs wrapped in a UI. I suppose they need all the help they can get
[09:26:29] Bitcoin Cash ... just another get rich quick scheme
[09:26:38] hmm :)
[09:26:51] I'll give it back to you, ok? ha ha. arrogance comes before the fall...
[09:27:17] maye we should have a little fun with CNv4 mining :)
[09:27:25] ;)
[09:27:38] come on. anyone who has watched their track record... $75M lost in ETH at DAO hack
[09:27:50] every smart contract that comes along is just waiting for another hack
[09:27:58] I just wanted to throw out the "in-protocol reward" thing, maybe someone sees the idea and wants to cowork. maybe not. maybe it's a stupid idea.
[09:29:18] linzhi-sonia: any thoughts on CN-GPU?
[09:29:55] CN-GPU has one positive aspect - it wastes chip area to implement all 18 hash algorithms
[09:30:19] you will always hear roughly the same feedback from me:
[09:30:52] "This algorithm very different, it heavy use floating point operations to hurt FPGAs and general purpose CPUs"
[09:30:56] the problem is, if it's profitable for people to buy ASIC miners and mine, it's always more profitable for the manufacturer to not sell and mine themselves
[09:31:02] "hurt"
[09:31:07] what is the point of this?
[09:31:15] it totally doesn't work
[09:31:24] you are hurting noone, just demonstrating lack of ability to think
[09:31:41] what is better: algo designed for chip, or chip designed for algo?
[09:31:43] fireice does it on daily basis, CN-GPU is a joke
[09:31:53] tevador: that's not really true, especially in a market with such large price fluctuations as cryptocurrency
[09:32:12] it's far less risky to sell miners than mine with them and pray that price doesn't crash for next six months
[09:32:14] I think it's great that crypto has a nice group of asicmakers now, hw & sw will cowork well
[09:32:36] jwinterm yes, that's why they premine them and sell after
[09:32:41] PoW is about being thermodynamically and cryptographically provable
[09:32:45] premining with them is taking on that risk
[09:32:49] not "fork when we think there are asics"
[09:32:51] business is about risk minimization
[09:32:54] that's just fear-driven
[09:33:05] Inge-: that's roughly the feedback
[09:33:24] I'm not saying it hasn't happened, but I think it's not so simple as saying "it always happens"
[09:34:00] jwinterm: it has certainly happened on BTC. and also on XMR.
[09:34:19] ironically, please think about it: these kinds of algos indeed prove the limits of the chips they were designed for. but they don't prove that you cannot implement the same algo differently! cannot!
[09:34:26] Risk minimization is not starting a business at all.
[09:34:34] proof-of-gpu-limit. proof-of-cpu-limit.
[09:34:37] imagine you have a money printing machine, would you sell it?
[09:34:39] proves nothing for an ASIC :)
[09:35:05] linzhi-sonia: thanks. I dont think anyone believes you can't make a more efficient cn-gpu asic than a gpu - but that it would not be orders of magnitude faster...
[09:35:24] ok
[09:35:44] like I say. these algos are, that's really ironic, designed to prove the limitatios of a particular chip in mind of the designer
[09:35:50] exactly the wrong way round :)
[09:36:16] like the cache size in RandomX :)
[09:36:18] beautiful
[09:36:29] someone looked at GPU designs
[09:37:31] linzhi-sonia can you elaborate? Cache size in RandomX was selected to fit CPU cache
[09:37:52] yes
[09:38:03] too large for GPU
[09:38:11] as I said, we are designing the algorithm to exactly fit CPU capabilities, I do not claim an ASIC cannot be more efficient
[09:38:16] ok!
[09:38:29] when will you do the audit?
[09:38:35] will the results be published in a document or so?
[09:38:37] I claim that single-chip ASIC is not viable, though
[09:39:06] you guys are brave, noone disputes that. 3 anti-asic hardforks now!
[09:39:18] 4th one coming
[09:39:31] 3 forks were done not only for this
[09:39:38] they had scheduled updates in the first place
[09:48:10] Monero is the #1 anti-asic fighter
[09:48:25] Monero is #1 for a lot of reasons ;)
[09:48:40] It's the coin with the most hycs.
[09:48:55] mooooo
[09:59:06] sneaky integer overflow, bug squished
[10:38:00] p0nziph0ne ([email protected]/vpn/privateinternetaccess/p0nziph0ne) has joined #monero-pow
[11:10:53] The convo here is wild
[11:12:29] it's like geo-politics at the intersection of software and hardware manufacturing for thermoeconomic value.
[11:13:05] ..and on a Sunday.
[11:15:43] midipoet: hw and sw should work together and stop silly games to devalue each other. to outsiders this is totally not attractive.
[11:16:07] I appreciate the positive energy here to try to listen, learn, understand.
[11:16:10] that's a start
[11:16:48] <-- p0nziph0ne ([email protected]/vpn/privateinternetaccess/p0nziph0ne) has quit (Quit: Leaving)
[11:16:54] we won't do silly mining against xmr "community" wishes, but not because we couldn'd do it, but because it's the wrong direction in the long run, for both sides
[11:18:57] linzhi-sonia: I agree to some extent. Though, in reality, there will always be divergence between social worlds. Not every body has the same vision of the future. Reaching societal consensus on reality tomorrow is not always easy
[11:20:25] absolutely. especially at a time when there is so much profit to be made from divisiveness.
[11:20:37] someone will want to make that profit, for sure
[11:24:32] Yes. Money distorts.
[11:24:47] Or wealth...one of the two
[11:26:35] Too much physical money will distort rays of light passing close to it indeed.

GPU Mining Crash Course - START HERE!

Welcome All to the GPUMining Crash Course!
With the increase in prices in cryptocurrency, a lot of people are getting back into mining and a lot of people are brand new to the concept overall. So, I quickly wrote this crash course to help you understand what to expect and how to successfully mine your first cryptocurrency. This crash course isn't gonna have all of the fluff you'd see in a normal publication. This is just everything you need to know to get up and running on your first cryptocurrency mining rig.

What is cryptocurrency mining?

One of the main things about cryptocurrencies is that they are "decentralized". Sounds great, but WTF does that even mean? Well, the easiest way to explain it is...
You know how if you want to send your friend/family money digitally, you can do so through your bank. Your bank likely takes a transaction fee and in a few days they will transfer the money. Since cryptocurrencies are decentralized, they don't have a bank or organization to fulfill the transfer of money. Instead, they outsource the computing power of their cryptocurrency network to miners (soon to be you). These miners are verifying transactions, securing the blockchain, and powering the cryptocurrency's specific network among other things. As an incentive, the miners collect transaction fees on the transactions that they verify and collect block rewards while new currency is still being introduced into the ecosystem.

What kind of rig should I build?

You can mine cryptocurrencies using your CPU, GPU, FPGA, or ASIC, but this is a GPU Mining subreddit, so I will cater this to GPUs.
For building a great all-around GPU rig, there are two models of GPUs that I'd recommend:
Both of these GPUs have solid hashrates across most mining algorithms and for a decent price! You should be able to find both of these kinds of GPUs used for around $200-$250 each, which is a great price if you know what happened during the last mining craze! ($200 GPUs were out of stock everywhere and people were reselling them for $600+ each)
There are also plenty of great AMD GPUs for mining, but I've worked mostly with Nvidia so that's why both of my recommendations are Nvidia and not AMD.
Other parts to your rig that you'll need are listed below. Most of these can be pieces of crap and are just needed to make the rig actually run, but the one spot you DON'T want to cheap out on is the power supply unit. A decent power supply unit will keep your home from burning down while also keeping your rigs up and running smoothly. Here are my recommendations:

She's built, now what?

Now you need to do a few things. I am a Windows miner, so I will be speaking to Windows here:
  1. Update Windows - Do all of the updates. Just do it.
  2. Update Drivers - Go to the EVGA website and download GeForce experience. It will keep your GPU drivers up to date.
  3. Go to Windows Device Manager and make sure all of your GPUs show up under "Display Adapters". If it is there, but it isn't showing the Name/Model of the GPU as the name, right click it and select "Update Driver". This should fix it.
Assuming you've done all of this, you're ready to download a mining application.

Mining Software

There are tons to choose from! Claymore, Phoenix, EWBF, LolMiner, etc... It can be overwhelming pretty quickly since they all have different algorithm support, speeds, efficiencies, and a whole lot more. On top of that, in order to get them running you need to set up batch files to call the proper exe, point you to the correct pool, and a whole bunch of other stuff that can be confusing to a new user. Not to mention, you will probably need a separate miner, config file, batch file, etc. for each different algorithm that you're interested in mining on.
Instead, I recommend that you download a miner management software that will take care of most of this tedious work for you. There are a few in the sidebar, but the /GPUMining favorite is AIOMiner. It was developed by our very own community member, xixspiderxix with the intention of making mining as easy as possible to do and without any fees. It supports over 100 different algorithms, so you'll be able to mine nearly ANY cryptocurrency you'd like. Just download it from their website and it will take you through a quick tutorial to help you get set up! You can also connect your rig to their website for remote monitoring and control. You've probably seen a few of their posts around this subreddit.
Other Windows mining softwares include:
Note: Many mining softwares have fees built into them. Most are around 1%, but can go as high as 5% or greater! You want a mining software with little or no fees at all so that you get to keep as much cryptocurrency as possible. These fees aren't something you actively pay, the software will automatically take it by mining on the developers behalf for a given amount of time and then switching back to mining on your own behalf. So, please be diligent in the software that you evaluate and make sure it is reputable.

I keep hearing about NiceHash. What is that?

The asshole of the mining industry. Jk, but not really.
NiceHash is a software program that allows you to sell your rig's hashing power to someone on their marketplace. They market themselves as profitable mining, but you're not really mining. You're selling your power in exchange for Bitcoin.
They did a great job telling people that with them, you're always mining the most profitable coin, but that's just not true. Since it is a mining marketplace, they make you mine whatever their most expensive contract is. If their contracts are below market prices, then you're not operating as efficiently and profitably as you could be.
NiceHash also has a sketchy history, which continues to this day. In 2017, they were hacked and lost $65M worth of Bitcoin. No one got paid out for MONTHS and many of their executives conveniently resigned. Their platform is also used to destroy cryptocurrencies. Since people are able to purchase mining power on their platform, people have used their platform to purchase enough mining power to control individual cryptocurrencies and duplicate coins, which increased the malicious user's wealth while completely destroying the integrity of the coin's blockchain. HoriZEN (formerly ZenCash), Ethereum Classic, and many other great cryptocurrencies have been the victim of NiceHash's platform.
For this and many other reasons, we highly recommend that you stay AWAY from Nicehash. We understand that it is extremely easy to use and you get paid in bitcoin, but they are destroying the industry with their greed and lack of motivation to change their platform for the protection of cryptocurrencies.

Concluding Thoughts

This is pretty much everything you need to know to get started. We covered the hardware, setting up the software, which software to use, and AIOMiner's tutorial will get you up to speed on how to actually mine the cryptocurrency that you want better than I can explain it, so I'll leave that part to them.
If you have any questions on this crash course, please leave a comment below where myself and other community members will be able to help you out.

Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners

Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners
Thank you for inviting Horizen to the GPU mining AMA!
ZEN had a great run of GPU mining that lasted well over a year, and brought lots of value to the early Zclassic miners. It is mined using Equihash protocol, and there have been ASIC miners available for the algorithm since about June of 2018. GPU mining is not really profitable for Horizen at this point in time.
We’ve got a lot of miners in the Horizen community, and many GPU miners also buy ASIC miners. Happy to talk about algorithm changes, security, and any other aspect of mining in the questions below. There are also links to the Horizen website, blog post, etc. below.
So, if I’m not here to ask you to mine, hold, and love ZEN, what can I offer? Notes on some of the lessons I’ve learned about maximizing mining profitability. An update on Horizen - there is life after moving on from GPU mining. As well as answering your questions during the next 7 days.

Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners

Author: Rolf Versluis - co-founder of Horizen

In GPU mining, just like in many of the activities involved with Bitcoin and cryptocurrencies, there is both a cycle and a progression. The Bitcoin price cycle is fairly steady, and by creating a personal handbook of actions to take during the cycle, GPU miners can maximize their profitability.
Maximizing profitability isn't the only aspect of GPU mining that is important, of course, but it is helpful to be able to invest in new hardware, and be able to have enough time to spend on building and maintaining the GPU miners. If it was a constant process that also involved losing money, then it wouldn't be as much fun.

Technology Progression

For a given mining algorithm, there is definitely a technology progression. We can look back on the technology that was used to mine Bitcoin and see how it first started off as Central Processing Unit (CPU) mining, then it moved to Graphical Processing Unit (GPU) mining, then Field Programmable Gate Array (FPGA), and then Application Specific Integrated Circuit (ASIC).
Throughout this evolution we have witnessed a variety of unsavory business practices that unfortunately still happen on occasion, like ASIC Miner manufacturers taking pre-orders 6 months in advance, GPU manufacturers creating commercial cards for large farms that are difficult for retail customers to secure and ASIC Miner manufacturers mining on gear for months before making it available for sale.
When a new crypto-currency is created, in many cases a new mining algorithm is created also. This is important, because if an existing algorithm was used, the coin would be open to a 51% attack from day one, and may not even be able to build a valid blockchain.
Because there's such a focus on profitable software, developers for GPU mining applications are usually able to write a mining application fairly rapidly, then iterate it to the limit of current GPU technology. If it looks like a promising new cryptocurrency, FPGA stream developers and ASIC Hardware Developers start working on their designs at the same time.
The people who create the hashing algorithms run by the miners are usually not very familiar with the design capabilities of Hardware manufacturers. Building application-specific semiconductors is an industry that's almost 60 years old now, and FPGA’s have been around for almost 35 years. This is an industry that has very experienced engineers using advanced design and modeling tools.
Promising cryptocurrencies are usually ones that are deploying new technology, or going after a big market, and who have at least a team of talented software developers. In the best case, the project has a full-stack business team involving development, project management, systems administration, marketing, sales, and leadership. This is the type of project that attracts early investment from the market, which will drive the price of the coin up significantly in the first year.
For any cryptocurrency that's a worthwhile investment of time, money, and electricity for the hashing, there will be a ASIC miners developed for it. Instead of fighting this technology progression, GPU miners may be better off recognizing it as inevitable, and taking advantage of the cryptocurrency cycle to maximize GPU mining profitability instead.

Cryptocurrency Price Cycle

For quality crypto projects, in addition to the one-way technology progression of CPU -> GPU -> FPGA -> ASIC, there is an upward price progression. More importantly, there is a cryptocurrency price cycle that oscillates around an overall upgrade price progression. Plotted against time, a cycle with an upward progressions looks like a sine wave with an ever increasing average value, which is what we see so far with the Bitcoin price.

Cryptocurrency price cycle and progression for miners
This means mining promising new cryptocurrencies with GPU miners, holding them as the price rises, and being ready to sell a significant portion in the first year. Just about every cryptocurrency is going to have a sharp price rise at some point, whether through institutional investor interest or by being the target of a pump-and-dump operation. It’s especially likely in the first year, while the supply is low and there is not much trading volume or liquidity on exchanges.
Miners need to operate in the world of government money, as well as cryptocurrency. The people who run mining businesses at some point have to start selling their mining proceeds to pay the bills, and to buy new equipment as the existing equipment becomes obsolete. Working to maximize profitability means more than just mining new cryptocurrencies, it also means learning when to sell and how to manage money.

Managing Cash for Miners

The worst thing that can happen to a business is to run out of cash. When that happens, the business usually shuts down and goes into bankruptcy. Sometimes an investor comes in and picks up the pieces, but at the point the former owners become employees.
There are two sides to managing cash - one is earning it, the other is spending it, and the cryptocurrency price cycle can tell the GPU miner when it is the best time to do certain things. A market top and bottom is easy to recognize in hindsight, and harder to see when in the middle of it. Even if a miner is able to recognize the tops and bottoms, it is difficult to act when there is so much hype and positivity at the top of the cycle, and so much gloom and doom at the bottom.
A decent rule of thumb for the last few cycles appears to be that at the top and bottom of the cycle BTC is 10x as expensive compared to USD as the last cycle. Newer crypto projects tend to have bigger price swings than Bitcoin, and during the rising of the pricing cycle there is the possibility that an altcoin will have a rise to 100x its starting price.
Taking profits from selling altcoins during the rise is important, but so is maintaining a reserve. In order to catch a 100x move, it may be worth the risk to put some of the altcoin on an exchange and set a very high limit order. For the larger cryptocurrencies like Bitcoin it is important to set trailing sell stops on the way up, and to not buy back in for at least a month if a sell stop gets triggered. Being able to read price charts, see support and resistance areas for price, and knowing how to set sell orders are an important part of mining profitability.

Actions to Take During the Cycle

As the cycle starts to rise from the bottom, this is a good time to buy mining hardware - it will be inexpensive. Also to mine and buy altcoins, which are usually the first to see a price rise, and will have larger price increases than Bitcoin.
On the rise of the cycle, this is a good time to see which altcoins are doing well from a project fundamentals standpoint, and which ones look like they are undergoing accumulation from investors.
Halfway through the rise of the cycle is the time to start selling altcoins for the larger project cryptos like Bitcoin. Miners will miss some of the profit at the top of the cycle, but will not run out of cash by doing this. This is also the time to stop buying mining hardware. Don’t worry, you’ll be able to pick up that same hardware used for a fraction of the price at the next bottom.
As the price nears the top of the cycle, sell enough Bitcoin and other cryptocurrencies to meet the following projected costs:
  • Mining electricity costs for the next 12 months
  • Planned investment into new miners for the next cycle
  • Additional funds needed for things like supporting a family or buying a Lambo
  • Taxes on all the capital gains from the sale of cryptocurrencies
It may be worth selling 70-90% of crypto holdings, maintaining a reserve in case there is second upward move caused by government bankruptcies. But selling a large part of the crypto is helpful to maintaining profitability and having enough cash reserves to make it through the bottom part of the next cycle.
As the cycle has peaked and starts to decline, this is a good time to start investing in mining facilities and other infrastructure, brush up on trading skills, count your winnings, and take some vacation.
At the bottom of the cycle, it is time to start buying both used and new mining equipment. The bottom can be hard to recognize.
If you can continue to mine all the way through bottom part of the cryptocurrency pricing cycle, paying with the funds sold near the top, you will have a profitable and enjoyable cryptocurrency mining business. Any cryptocurrency you are able to hold onto will benefit from the price progression in the next higher cycle phase.

An Update on Horizen - formerly ZenCash

The team at Horizen recognizes the important part that GPU miners played in the early success of Zclassic and ZenCash, and there is always a welcoming attitude to any of ZEN miners, past and present. About 1 year after ZenCash launched, ASIC miners became available for the Equihash algorithm. Looking at a chart of mining difficulty over time shows when it was time for GPU miners to move to mining other cryptocurrencies.

Horizen Historical Block Difficulty Graph
Looking at the hashrate chart, it is straightforward to see that ASIC miners were deployed starting June 2018. It appears that there was a jump in mining hashrate in October of 2017. This may have been larger GPU farms switching over to mine Horizen, FPGA’s on the network, or early version of Equihash ASIC miners that were kept private.
The team understands the importance of the cryptocurrency price cycle as it affects the funds from the Horizen treasury and the investments that can be made. 20% of each block mined is sent to the Horizen non-profit foundation for use to improve the project. Just like miners have to manage money, the team has to decide whether to spend funds when the price is high or convert it to another form in preparation for the bottom part of the cycle.
During the rise and upper part of the last price cycle Horizen was working hard to maximize the value of the project through many different ways, including spending on research and development, project management, marketing, business development with exchanges and merchants, and working to create adoption in all the countries of the world.
During the lower half of the cycle Horizen has reduced the team to the essentials, and worked to build a base of users, relationships with investors, exchanges, and merchants, and continue to develop the higher priority software projects. Lower priority software development, going to trade shows, and paying for business partnerships like exchanges and applications have all been completely stopped.
Miners are still a very important part of the Horizen ecosystem, earning 60% of the block reward. 20% goes to node operators, with 20% to the foundation. In the summer of 2018 the consensus algorithm was modified slightly to make it much more difficult for any group of miners to perform a 51% attack on Horizen. This has so far proven effective.
The team is strong, we provide monthly updates on a YouTube live stream on the first Wednesday of each month where all questions asked during the stream are addressed, and our marketing team works to develop awareness of Horizen worldwide. New wallet software was released recently, and it is the foundation application for people to use and manage their ZEN going forward.
Horizen is a Proof of Work cryptocurrency, and there is no plan to change that by the current development team. If there is a security or centralization concern, there may be change to the algorithm, but that appears unlikely at this time, as the hidden chain mining penalty looks like it is effective in stopping 51% attacks.
During 2019 and 2020 the Horizen team plans to release many new software updates:
  • Sidechains modification to main software
  • Sidechain Software Development Kit
  • Governance and Treasury application running on a sidechain
  • Node tracking and payments running on a sidechain
  • Conversion from blockchain to a Proof of Work BlockDAG using Equihash mining algorithm
After these updates are working well, the team will work to transition Horizen over to a governance model where major decisions and the allocation of treasury funds are done through a form of democratic voting. At this point all the software developed by Horizen is expected to be open source.
When the governance is transitioned, the project should be as decentralized as possible. The goal of decentralization is to enable resilience and preventing the capture of the project by regulators, government, criminal organizations, large corporations, or a small group of individuals.
Everyone involved with Horizen can be proud of what we have accomplished together so far. Miners who were there for the early mining and growth of the project played a large part in securing the network, evangelizing to new community members, and helping to create liquidity on new exchanges. Miners are still a very important part of the project and community. Together we can look forward to achieving many new goals in the future.

Debunking myths about mining and GPUs

E: Going to bed, will contribute more tomorrow. Thanks for the discussion!
Myth: Mining is more stressful than gaming. Fact: It depends. During the old days, this was plausible, because older GPUs (Pre-polaris) are/were bottlenecked by core clock when mining the most profitable coins. Thus, miners overclocked and overvolted these cards quite frequently, especially with cheap electricity. This meant that those cards were often run hot, pushing the limits and stressing VRM and fans quite a lot. Nowadays, ethash (Ethereum) is the most profitable algorithm for AMD cards 99% of the time, and newer GPUs (Polaris) are limited by memory bandwidth and latency. Miners can underclock core to the low 1100MHz range before seeing performance drop. To save power, miners who know what they are doing also undervolt, since it is no longer necessary to sustain a high core clock. Thus, it is quite feasible to run polaris cards below 70C at a reasonable fan speed. However, dual mining (mining more than one coin at once) does increase power consumption by up to 20%, and there are also idiots who run their polaris cards OCd while mining. With the exception of a few idiots, miners treat their Polaris GPUs pretty much the same; that is, running underclocked and undervolted 24/7 with a memory strap mod and mem OC. On the other hand, former gaming cards are highly variable in use cases. Some gamers leave their cards at stock settings, some undervolt, and some OC and/or overvolt. Most of the time, these cards are thermal cycled far more often than mining cards, which is known to weaken solder. Another thing to consider is that manufacturers have learned (somewhat) from their mistakes of putting shit tier fans in GPUs, and many fans on modern GPUs are ball bearing and/or swappable. Even some budget cards, such as MSI Armor, use decent ball bearing fans. Bottom line: the risk of buying mined Polaris cards is not as high as the risk of buying older mined cards. I would not be against buying mined polaris cards, but it's not necessarily better than buying a gamer's card instead. At the end of the day, it depends more on how the owner treated it than what they used it for.
Myth: GPUs are obsolete because of FPGAs and ASICs Fact: Mostly false. Older algorithms such as scrypt and SHA256 (lite/doge/feathebitcoin etc) are no longer feasible to mine with GPUs, but there have been multiple algorithms since then that are built to deter ASICs; most of the time it is done by making it memory-hard because designing an ASIC with high memory throughput is considerably more expensive to design and manufacture. Many devs prefer their blockchain to be ASIC resistant to avoid the concentration of power problem that Bitcoin is having nowadays, where a giant, near-monopolistic ASIC manufacturer (Bitmain) is causing a lot of (subjective) controversy. Blockchains based on ethash (Ethereum and its forks), equihash (Zcash and its forks) and cryptonight (Monero and forks) are some examples, but there are scores of other shitcoins and a few other algos that are GPU dominant. It is almost impossible that there will be another ASIC takeover, which is what was responsible for the stop in GPU demand in the bitcoin and litecoin days. Bottom line: ASICs no longer threaten GPU miners, or the demand for GPUs
Myth: Ethereum switching to Proof of Stake will kill mining soon Fact: Doomsayers have been preaching about proof of stake since late 2015. It has always been "coming soon." The fact is, the Ethereum roadmap goes from proof of work (mining) -> Casper (mining + PoS) -> Metropolis (PoS). Currently, the release date of Casper is not even announced yet, nor is it being tested in a (public) testnet. Proof of Stake might one day take over, but mining is here to stay for a while yet. Another thing to consider is that there are tons of other GPU mineable blockchains, and although Ethereum is biggest, it is certainly feasible that mining stays profitable even after Ethereum goes PoS (if it ever does). However, it is possible that profits will be low enough to discourage new miners. Bottom line: It's very unlikely. E: I screwed up the roadmap; here is a better source than me with some interesting information: https://www.ethnews.com/ethereums-vitalik-buterin-gives-keynote-on-metropolis
Myth: The current Ethereum demand spike is a bubble Opinion: Honestly, I don't know. I would not be surprised if stricter regulations on ICOs come sooner or later, which would fuck with Ether prices. There is also the inherent volatility of cryptocurrencies. However, it is also possible that blockchain technology continues to gain traction; that is, the price could just as easily go up as go down. Although it's fun to read about other people's opinions, only time-travelling wizards can tell you when it will become economical again to upgrade your poor HD5770. Bottom line: No one knows.
Myth: Miners will "steal" all the RX Vegas Fact: Only a reckless miner would buy Vegas on release, since mining performance is not known. In fact, it is possible that it can't mine at all (or at some stupidly low speed) until devs add support to existing miners. It would be even more reckless than gamers who buy without seeing benchmarks, since at least gamers can expect the games to actually run. It's also not necessarily the case that Vega will be good once miners do add support. Maybe there will be enough reckless miners to affect supply, maybe not. Of course, it is possible that miners will deplete the supply after it is demonstrated that Vega is good for mining. Bottom line: Most miners won't preorder, but it's possible that a significant number will. E: Important to remember that even if mining demand isn't high, doesn't mean that supply will be plentiful.
Myth: Nvidia cards SUCK at mining Fact: Mostly false. They USED to suck in the old pre-Maxwell days, but now they are actually more efficient at mining Ethereum and Zcash compared to AMD cards, even after both cards are undervolted. The flipside is that they (used to) cost more for the equivalent hashrate. For reference, my old 5xRX470 rig drew just under 800W when mining ETH only and hashed at 150MH/s. My current 6xGTX1060 rig draws just over half of that (<450W) and hashes at about 135MH/s. Certainly not as good in raw performance, but they are viable nonetheless, especially given the AMD GPU shortage. In fact, Nvidia cards (1060 and especially 1070) are becoming scarce as well. Bottom line: Nvidia is still the underdog when it comes to mining, but far from irrelevant nowadays.
Myth: 4GB cards will be obsolete for mining soon Fact: FALSE. The Ethereum DAG is not even 3GB yet, and won't be for a few months. The recent reports of 4GB Polaris cards slowing down soon due to DAG size is caused by limited TLB capacity, not VRAM restrictions. Polaris cards will still be able to mine ETH forks such as Expanse and UBIQ without diminished speed, and even if they are used to mine ETH, it is not that much of a performance hit at first. It would certainly not make polaris useless or undesirable for mining anytime soon. Tahiti GPUs already suffer from this issue and Hawaii is the most resistant to this issue. Have not benched Nvidia at a later epoch.
Myth: Creating miner-bashing posts on Reddit will help alleviate the GPU supply problem Fact: False, you are simply giving cryptocurrencies and mining more exposure to the general public, increasing demand.
Myth: Mining-specific GPUs will solve the shortage problems Opinion: There's not enough info to tell yet, but I am a skeptic for the following reasons. First, no display limits the resale value of the card for obvious reasons. IMO, the whole point of crypto mining from a profitability standpoint is to have a hedge against coin volatility (hardware is still worth something if the coin crashes). Otherwise it is much less effort to just buy and hold the coin. If the hardware is useless without demand from other (significant) sources, then it doesn't make much sense to buy it unless the price is extremely low. I'm sure that cost-downing the PCB and warranty will make for a cheap card, but it has to be extremely cheap and plentiful in supply, or else miners will buy whatever they can get. I could envision "failed" chips (not meeting spec of consumer editions) being stuck in miner cards, but I doubt there are enough to meet demand without ramping up production as a whole, which carries its own risks. I guess that it would help a little, but probably not solve the problems. Alternatively, since modern GPUs are bottlenecked by RAM when mining, it might be enticing to miners to have the fastest (GDDR5) RAM on the market (probably the 9gbps chips from the 1060 6G 9gbps edition, although I don't have one to test). However, my previous points still apply; buying such a card without display outputs carries a big risk. Bottom line: It's not a great idea, unless they are super cheap or use really good RAM.
Hope this helped; if you have any further questions I will try to answer them. I'm both a gamer and miner who uses both AMD and Nvidia roughly equally and don't favor one group over another. I've mined and gamed on all high end AMD GPUs since Tahiti (except Tonga) and all Pascal cards except 1050ti.

Best $100-$300 FPGA development board in 2018?

Hello, I’ve been trying to decide on a FPGA development board, and have only been able to find posts and Reddit threads from 4-5 years ago. So I wanted to start a new thread and ask about the best “mid-range” FGPA development board in 2018. (Price range $100-$300.)
I started with this Quora answer about FPGA boards, from 2013. The Altera DE1 sounded good. Then I looked through the Terasic DE boards.
Then I found this Reddit thread from 2014, asking about the DE1-SoC vs the Cyclone V GX Starter Kit: https://www.reddit.com/FPGA/comments/1xsk6w/cyclone_v_gx_starter_kit_vs_de1soc_board/‬ (I was also leaning towards the DE1-SoC.)
Anyway, I thought I better ask here, because there are probably some new things to be aware of in 2018.
I’m completely new to FPGAs and VHDL, but I have experience with electronics/microcontrollers/programming. My goal is to start with some basic soft-core processors. I want to get some C / Rust programs compiling and running on my own CPU designs. I also want to play around with different instruction sets, and maybe start experimenting with asynchronous circuits (e.g. clock-less CPUs)
Also I don’t know if this is possible, but I’d like to experiment with ternary computing, or work with analog signals instead of purely digital logic. EDIT: I just realized that you would call those FPAAs, i.e. “analog” instead of “gate”. Would be cool if there was a dev board that also had an FPAA, but no problem if not.
EDIT 2: I also realized why "analog signals on an FPGA" doesn't make any sense, because of how LUTs work. They emulate boolean logic with a lookup table, and the table can only store 0s and 1s. So there's no way to emulate a transistor in an intermediate state. I'll just have play around with some transistors on a breadboard.
UPDATE: I've put together a table with some of the best options:
Board Maker Chip LUTs Price SoC? Features
icoBoard Lattice iCE40-HX8K 7,680 $100 Sort of A very simple FPGA development board that plugs into a Raspberry Pi, so you have a "backup" hard-core CPU that can control networking, etc. Supports a huge range of pmod accessories. You can write a program/circuit so that the Raspberry Pi CPU and the FPGA work together, similar to a SoC. Proprietary bitstream is fully reverse engineered and supported by Project IceStorm, and there is an open-source toolchain that can compile your hardware design to bitstream. Has everything you need to start experimenting with FPGAs.
iCE40-HX8K Breakout Board Lattice iCE40-HX8K-CT256 7,680 $49 No 8 LEDs, 8 switches. Very similar to icoBoard, but no Raspberry Pi or pmod accessories.
iCE40 UltraPlus Lattice iCE40 UltraPlus FPGA 5280 $99 No Chip specs. 4 switchable FPGAs, and a rechargeable battery. Bluetooth module, LCD Display (240 x 240 RGB), RGB LED, microphones, audio output, compass, pressure, gyro, accelerometer.
Go Board Lattice ICE40 HX1K FPGA 1280 $65 No 4 LEDs, 4 buttons, Dual 7-Segment LED Display, VGA, 25 MHz on-board clock, 1 Mb Flash.
snickerdoodle Xilinx Zynq 7010 28K $95 Yes Xilinx Zynq 7-Series SoC - ARM Cortex-A9 processor, and Artix-7 FPGA. 125 IO pins. 1GB DDR2 RAM. Texas Instruments WiLink 8 wireless module for 802.11n Wi-Fi and Bluetooth 4.1. No LEDs or buttons, but easy to wire up your own on a breadboard. If you want to use a baseboard, you'll need a snickerdoodle black ($195) with the pins in the "down" orientation. (E.g. The "breakyBreaky breakout board" ($49) or piSmasher SBC ($195)). The snickerdoodle one only comes with pins in the "up" orientation and doesn't support any baseboards. But you can still plug the jumpers into the pins and wire up things on a breadboard.
numato Mimas A7 Xilinx Artix 7 52K $149 No 2Gb DDR3 RAM. Gigabit Ethernet. HDMI IN/OUT. 100MHz LVDS oscillator. 80 IOs. 7-segment display, LEDs, buttons. (Found in this Reddit thread.)
Ultra96 Xilinx Zynq UltraScale+ ZU3EG 154K $249 Yes Has one of the latest Xilinx SoCs. 2 GB (512M x32) LPDDR4 Memory. Wi-Fi / Bluetooth. Mini DisplayPort. 1x USB 3.0 type Micro-B, 2x USB 3.0 Type A. Audio I/O. Four user-controllable LEDs. No buttons and limited LEDs, but easy to wire up your own on a breadboard
Nexys A7-100T Xilinx Artix 7 15,850 $265 No . 128MiB DDR2 RAM. Ethernet port, PWM audio output, accelerometer, PDM microphone, microphone, etc. 16 switches, 16 LEDs. 7 segment displays. USB HID Host for mice, keyboards and memory sticks.
Zybo Z7-10 Xilinx Zynq 7010 17,600 $199 Yes Xilinx Zynq 7000 SoC (ARM Cortex-A9, 7-series FPGA.) 1 GB DDR3 RAM. A few switches, push buttons, and LEDs. USB and Ethernet. Audio in/out ports. HDMI source + sink with CEC. 8 Total Processor I/O, 40 Total FPGA I/O. Also a faster version for $299 (Zybo Z7-20).
Arty A7 Xilinx Artix 7 15K $119 No 256MB DDR3L. 10/100 Mbps Ethernet. A few switches, buttons, LEDs.
DE10-Standard (specs) Altera Cyclone V 110K $350 Yes Dual-core Cortex-A9 processor. Lots of buttons, LEDs, and other peripherals.
DE10-Nano Altera Cyclone V 110K $130 Yes Same as DE10-Standard, but not as many peripherals, buttons, LEDs, etc.

Winner:

icoBoard ($100). (Buy it here.)
The icoBoard plugs into a Raspberry Pi, so it's similar to having a SoC. The iCE40-HX8K chip comes with 7,680 LUTs (logic elements.) This means that after you learn the basics and create some simple circuits, you'll also have enough logic elements to run the VexRiscv soft-core CPU (the lightweight Murax SoC.)
The icoBoard also supports a huge range of pluggable pmod accessories:
You can pick whatever peripherals you're interested in, and buy some more in the future.
Every FPGA vendor keeps their bitstream format secret. (Here's a Hacker News discussion about it.) The iCE40-HX8K bitstream has been fully reverse engineered by Project IceStorm, and there is an open-source set of tools that can compile Verilog to iCE40 bitstream.
This means that you have the freedom to do some crazy experiments, like:
You don't really have the same freedom to explore these things with Xilinx or Altera FPGAs. (Especially asynchronous circuits.)

Links:

Second Place:

iCE40-HX8K Breakout Board ($49)

Third Place:

numato Mimas A7 ($149).
An excellent development board with a Xilinx Artix 7 FPGA, so you can play with a bigger / faster FPGA and run a full RISC-V soft-core with all the options enabled, and a much higher clock speed. (The iCE40 FPGAs are a bit slow and small.)
Note: I've changed my mind several times as I learned new things. Here's some of my previous thoughts.

What did I buy?

I ordered a iCE40-HX8K Breakout Board to try out the IceStorm open source tooling. (I would have ordered an icoBoard if I had found it earlier.) I also bought a numato Mimas A7 so that I could experiment with the Artix 7 FPGA and Xilinx software (Vivado Design Suite.)

Questions

What can I do with an FPGA? / How many LUTs do I need?

X21S

This hashing algorithm was created specifically for Ritocoin, and was designed to resist FPGAs, ASICs, and NiceHash. It is X16S (16 algorithms shuffled and hashed),, followed by 5 additional hashing algorithms: haval256, tiger, lyra2, gost512, and sha256. The inclusion of lyra2 brings numerous advantages, making parallelization of the algorithm practically impossible, with each step relying on the previous step having already been computed. It is a “friendly” algorithm that makes GPUs produce much less heat and uses less electricity during mining.

Take your time to learn more about us in the below story of Ritocoin...

The spirit of Bitcoin continues to inspire, empower and enable people around the globe. Ten years later, just as it seemed Bitcoin was being defined by commercial agents and regulated governance, that same free and independent spirit imbued the Ravencoin community. In ten short months, however, 30% of the Ravencoin project’s net hash comes from NiceHash and the looming impact of the imminent FPGA mining cards and X16R bitstreams certainly promises to shake up the dream of this GPU miner’s darling.

Ravencoin’s fair launch genuinely inspired our developers and supporters. We admire the way Ravencoin came out swinging — fighting for fairness, an honest distribution of coins and a place where GPU miners could thrive. The asset layer attracted many more miners and investors to the pools. Many Ritocoin enthusiasts came from the Ravencoin community, and continue their association with that project.

The whole crypto ecosystem should appreciate the work begun by Ravencoin. Obviously they continue to inspire and motivate us to this day. It’s the reason we took action. We decided to start our own project which focuses upon at least two pillars of decentralized networks in the crypto space: community governance and a fair distribution of coins. It is a core belief throughout Ritocoin that in order to successfully develop and maintain this hacker’s playground — a place where a broad range of ideas could be tried and allowed to flourish — these two ideals must be allowed to drive and guide our community.

This deep focus on community choices creates a project flexible enough to support most ideas, and agile enough to define new frontiers.

A mining network’s distributed ledger is defined by its technology. Like many in the broader crypto-mining community, we value the GPU for its accessibility. These processors are available for purchase all around the world without any legal restrictions. GPUs are vastly more accessible for hobbyists and miners to acquire. They can be shipped nearly anywhere around the globe, a nice benefit to the popular secondary market which has sprung up much to the chagrin of PC gamers.

More constraints exist for the ASIC and FPGA miner. Laws in some parts of the world restrict people from using or buying ASIC and FPGA mining hardware. This alone is directly in confrontation with Ritocoin’s core values of decentralized stewardship and sovereignty.

The GPU, in essence, is like your voice. Anyone with the means of acquiring one GPU should be able to have their voice heard. ASIC and FPGA mining devalues the GPU miner’s voice and silos that coin’s network away from the small scale and personal mining operator. A truly community driven project means each stakeholder, regardless of size of contribution to the network’s net hash, has an opportunity to build, vote and direct.

If you are already familiar with our website, discord or whitepaper, you are probably aware that masternodes had been proposed as a feature of the network from the beginning. This opened the door to ongoing discussions in the Ritocoin community regarding

● A masternode’s true purpose

● What benefit they provide to the project

● How the benefit is realized

● The collateral

This discussion, governed entirely by stakeholders across the extended network yielded a defining moment for our vision of flexibility. We have not yet found the potential utility of masternodes, however, the conversation has not reached an extent to where we could abandon the idea. To quote one of our developers during this discussion on our Discord:

“Just want to give a reminder here that even though masternodes are on the roadmap, it is not set in stone. This coin belongs to the community and we will do what we as a community want to do. If we conclude that we want to take this coin a different direction than masternodes, then that is what we’ll do.” --traysi

We are all volunteers at Ritocoin. Our moderators and community leaders try to give immediate support to all users that require it. Contact us in Discord or Telegram, not only for support, but, proposing new ideas, revising old ones and just so you can find a place to get together and find people to hang out with. You are well within your rights to enjoy yourself at any given moment, and, should you feel so inclined to begin working with the team, we just so happen to be looking for ambitious individuals that see themselves as being part of a greater vision, are inspired by change, and inspired to be the change they want to see making things better in this world.

Join us in a space where your ideas to build something great can become a reality. We are eager to know what you think is best for the future of Rito. What steps would you take to become more resilient, stronger, fair and decentralized? Because at the end of the day, like it or not, love it or leave it.. this is your coin, too.

You can become a significant part of this project. We will help you further develop the role you wish to fill in the cryptocurrency space — influencer, developer, analyst, you name it. This is not a just-for-developer’s playground. We want the enthusiasts. We want the perplexed and the rabbit-hole divers. This is the coin for everyone who is trying to find their place on the path that Satoshi began unfolding in 2008 after the collapse of the housing market rippled out into the subsequent crash of global markets. That’s why we have Bitcoin, remember? Be your own bank. This is why Satoshi and Bitcoin.org kept their software open source. It’s up to us to keep the torch ablaze.

Community funds

For the first year, about 1% of mined coins are set aside into a developers fund that is used to provide bounties to the community developers who make substantial development contributions to the Ritocoin ecosystem. We have already paid out numerous bounties for important work that has already benefits Ritocoin in substantial ways. We also have another donation-driven community fund that has recently been put together for the purposes of doing fun contests and things like that.

Cooperation and collaborations

We have discovered a number of fatal flaws in the original Ravencoin codebase and worked with the Ravencoin developers to get those fixed in both Ritocoin and Ravencoin. This work has benefitted Ravencoin in numerous ways and we look forward to a long time of collaboration and cooperation between us and them. Many members of the Safecoin team are also in our discord group, and have collaborated with us in shaping the future decisions of Ritocoin. We have several thousand members in our group and they represent all walks of cryptocurrency life. We invite all coin developers, miners and enthusiasts to join our discord and be a part of this coin that truly belongs entirely to the community.

Block reward

A couple weeks ago we met for a scheduled meeting in our discord group and had a lengthy conversation about the block reward. Our block reward started at 5,000 RITO per block (every 60 seconds) just like Ravencoin. This extremely high number of coins coupled with the high profitability of mining led to unforeseen consequences with pools auto-exchanging the coin into bitcoin. This dumping by non-community miners had a very negative impact on the community sentiment and morale, as we watched the exchange price plunge. We looked at other coins and realized that this fate has befell many other coins with high block rewards. Following much discussion, we decided to change the reward structure. Starting around March 19th the block rewards will start to slowly go down in a curve until it reaches 1,000. Then the reduction will be even more slowed down with block rewards exponentially dropping at periodic intervals. We have posted charts on our website that shows what the long-term effects of our reward reducing algorithms will be. As a miner, the next 2 months will be a great time to mine and hold, while the block reward is still fairly high. We encourage all miners and cryptocurrency enthusiasts to take advantage of the current favourable block reward and build a nice holding for yourself. Then join the community and be a part of the fun we’re having with this project.
This post was prepared by a collaboration of multiple Ritocoin members and was posted to reddit by the core developer Trevali, who posts to reddit under the ritocoin username and will be very happy to answer any questions anybody may have about our project. Traysi (well known in the Ravencoin community) is also an active Ritocoin developer and may come to this thread if needed.
We welcome any questions from any of you regarding our project!

The Problem with PoW

The Problem with PoW
Miners have always had it rough..
"Frustrated Miners"

The Problem with PoW
(and what is being done to solve it)

Proof of Work (PoW) is one of the most commonly used consensus mechanisms entrusted to secure and validate many of today’s most successful cryptocurrencies, Bitcoin being one. Battle-hardened and having weathered the test of time, Bitcoin has demonstrated the undeniable strength and reliability of the PoW consensus model through sheer market saturation, and of course, its persistency.
In addition to the cost of powerful computing hardware, miners prove that they are benefiting the network by expending energy in the form of electricity, by solving and hashing away complex math problems on their computers, utilizing any suitable tools that they have at their disposal. The mathematics involved in securing proof of work revolve around unique algorithms, each with their own benefits and vulnerabilities, and can require different software/hardware to mine depending on the coin.
Because each block has a unique and entirely random hash, or “puzzle” to solve, the “work” has to be performed for each block individually and the difficulty of the problem can be increased as the speed at which blocks are solved increases.

Hashrates and Hardware Types

While proof of work is an effective means of securing a blockchain, it inherently promotes competition amongst miners seeking higher and higher hashrates due to the rewards earned by the node who wins the right to add the next block. In turn, these higher hash rates benefit the blockchain, providing better security when it’s a result of a well distributed/decentralized network of miners.
When Bitcoin first launched its genesis block, it was mined exclusively by CPUs. Over the years, various programmers and developers have devised newer, faster, and more energy efficient ways to generate higher hashrates; some by perfecting the software end of things, and others, when the incentives are great enough, create expensive specialized hardware such as ASICs (application-specific integrated circuit). With the express purpose of extracting every last bit of hashing power, efficiency being paramount, ASICs are stripped down, bare minimum, hardware representations of a specific coin’s algorithm.
This gives ASICS a massive advantage in terms of raw hashing power and also in terms of energy consumption against CPUs/GPUs, but with significant drawbacks of being very expensive to design/manufacture, translating to a high economic barrier for the casual miner. Due to the fact that they are virtual hardware representations of a single targeted algorithm, this means that if a project decides to fork and change algorithms suddenly, your powerful brand-new ASIC becomes a very expensive paperweight. The high costs in developing and manufacturing ASICs and the associated risks involved, make them unfit for mass adoption at this time.
Somewhere on the high end, in the vast hashrate expanse created between GPU and ASIC, sits the FPGA (field programmable gate array). FPGAs are basically ASICs that make some compromises with efficiency in order to have more flexibility, namely they are reprogrammable and often used in the “field” to test an algorithm before implementing it in an ASIC. As a precursor to the ASIC, FPGAs are somewhat similar to GPUs in their flexibility, but require advanced programming skills and, like ASICs, are expensive and still fairly uncommon.

2 Guys 1 ASIC

One of the issues with proof of work incentivizing the pursuit of higher hashrates is in how the network calculates block reward coinbase payouts and rewards miners based on the work that they have submitted. If a coin generated, say a block a minute, and this is a constant, then what happens if more miners jump on a network and do more work? The network cannot pay out more than 1 block reward per 1 minute, and so a difficulty mechanism is used to maintain balance. The difficulty will scale up and down in response to the overall nethash, so if many miners join the network, or extremely high hashing devices such as ASICs or FPGAs jump on, the network will respond accordingly, using the difficulty mechanism to make the problems harder, effectively giving an edge to hardware that can solve them faster, balancing the network. This not only maintains the block a minute reward but it has the added side-effect of energy requirements that scale up with network adoption.
Imagine, for example, if one miner gets on a network all alone with a CPU doing 50 MH/s and is getting all 100 coins that can possibly be paid out in a day. Then, if another miner jumps on the network with the same CPU, each miner would receive 50 coins in a day instead of 100 since they are splitting the required work evenly, despite the fact that the net electrical output has doubled along with the work. Electricity costs miner’s money and is a factor in driving up coin price along with adoption, and since more people are now mining, the coin is less centralized. Now let’s say a large corporation has found it profitable to manufacture an ASIC for this coin, knowing they will make their money back mining it or selling the units to professionals. They join the network doing 900 MH/s and will be pulling in 90 coins a day, while the two guys with their CPUs each get 5 now. Those two guys aren’t very happy, but the corporation is. Not only does this negatively affect the miners, it compromises the security of the entire network by centralizing the coin supply and hashrate, opening the doors to double spends and 51% attacks from potential malicious actors. Uncertainty of motives and questionable validity in a distributed ledger do not mix.
When technology advances in a field, it is usually applauded and welcomed with open arms, but in the world of crypto things can work quite differently. One of the glaring flaws in the current model and the advent of specialized hardware is that it’s never ending. Suppose the two men from the rather extreme example above took out a loan to get themselves that ASIC they heard about that can get them 90 coins a day? When they join the other ASIC on the network, the difficulty adjusts to keep daily payouts consistent at 100, and they will each receive only 33 coins instead of 90 since the reward is now being split three ways. Now what happens if a better ASIC is released by that corporation? Hopefully, those two guys were able to pay off their loans and sell their old ASICs before they became obsolete.
This system, as it stands now, only perpetuates a never ending hashrate arms race in which the weapons of choice are usually a combination of efficiency, economics, profitability and in some cases control.

Implications of Centralization

This brings us to another big concern with expensive specialized hardware: the risk of centralization. Because they are so expensive and inaccessible to the casual miner, ASICs and FPGAs predominantly remain limited to a select few. Centralization occurs when one small group or a single entity controls the vast majority hash power and, as a result, coin supply and is able to exert its influence to manipulate the market or in some cases, the network itself (usually the case of dishonest nodes or bad actors).
This is entirely antithetical of what cryptocurrency was born of, and since its inception many concerted efforts have been made to avoid centralization at all costs. An entity in control of a centralized coin would have the power to manipulate the price, and having a centralized hashrate would enable them to affect network usability, reliability, and even perform double spends leading to the demise of a coin, among other things.
The world of crypto is a strange new place, with rapidly growing advancements across many fields, economies, and boarders, leaving plenty of room for improvement; while it may feel like a never-ending game of catch up, there are many talented developers and programmers working around the clock to bring us all more sustainable solutions.

The Rise of FPGAs

With the recent implementation of the commonly used coding language C++, and due to their overall flexibility, FPGAs are becoming somewhat more common, especially in larger farms and in industrial setting; but they still remain primarily out of the hands of most mining enthusiasts and almost unheard of to the average hobby miner. Things appear to be changing though, one example of which I’ll discuss below, and it is thought by some, that soon we will see a day when mining with a CPU or GPU just won’t cut it any longer, and the market will be dominated by FPGAs and specialized ASICs, bringing with them efficiency gains for proof of work, while also carelessly leading us all towards the next round of spending.
A perfect real-world example of the effect specialized hardware has had on the crypto-community was recently discovered involving a fairly new project called VerusCoin and a fairly new, relatively more economically accessible FPGA. The FPGA is designed to target specific alt-coins whose algo’s do not require RAM overhead. It was discovered the company had released a new algorithm, kept secret from the public, which could effectively mine Verus at 20x the speed of GPUs, which were the next fastest hardware types mining on the Verus network.
Unfortunately this was done with a deliberately secret approach, calling the Verus algorithm “Algo1” and encouraging owners of the FPGA to never speak of the algorithm in public channels, admonishing a user when they did let the cat out of the bag. The problem with this business model is that it is parasitic in nature. In an ecosystem where advancements can benefit the entire crypto community, this sort of secret mining approach also does not support the philosophies set forth by the Bitcoin or subsequent open source and decentralization movements.
Although this was not done in the spirit of open source, it does hint to an important step in hardware innovation where we could see more efficient specialized systems within reach of the casual miner. The FPGA requires unique sets of data called a bitstream in order to be able to recognize each individual coin’s algorithm and mine them. Because it’s reprogrammable, with the support of a strong development team creating such bitstreams, the miner doesn’t end up with a brick if an algorithm changes.

All is not lost thanks to.. um.. Technology?

Shortly after discovering FPGAs on the network, the Verus developers quickly designed, tested, and implemented a new, much more complex and improved algorithm via a fork that enabled Verus to transition smoothly from VerusHash 1.0 to VerusHash 2.0 at block 310,000. Since the fork, VerusHash 2.0 has demonstrated doing exactly what it was designed for- equalizing hardware performance relative to the device being used while enabling CPUs (the most widely available “ASICs”) to mine side by side with GPUs, at a profit and it appears this will also apply to other specialized hardware. This is something no other project has been able to do until now. Rather than pursue the folly of so many other projects before it- attempting to be “ASIC proof”, Verus effectively achieved and presents to the world an entirely new model of “hardware homogeny”. As the late, great, Bruce Lee once said- “Don’t get set into one form, adapt it and build your own, and let it grow, be like water.”
In the design of VerusHash 2.0, Verus has shown it doesn’t resist progress like so many other new algorithms try to do, it embraces change and adapts to it in the way that water becomes whatever vessel it inhabits. This new approach- an industry first- could very well become an industry standard and in doing so, would usher in a new age for proof of work based coins. VerusHash 2.0 has the potential to correct the single largest design flaw in the proof of work consensus mechanism- the ever expanding monetary and energy requirements that have plagued PoW based projects since the inception of the consensus mechanism. Verus also solves another major issue of coin and net hash centralization by enabling legitimate CPU mining, offering greater coin and hashrate distribution.
Digging a bit deeper it turns out the Verus development team are no rookies. The lead developer Michael F Toutonghi has spent decades in the field programming and is a former Vice President and Technical Fellow at Microsoft, recognized founder and architect of Microsoft's .Net platform, ex-Technical Fellow of Microsoft's advertising platform, ex-CTO, Parallels Corporation, and an experienced distributed computing and machine learning architect. The project he helped create employs and makes use of a diverse myriad of technologies and security features to form one of the most advanced and secure cryptocurrency to date. A brief description of what makes VerusCoin special quoted from a community member-
"Verus has a unique and new consensus algorithm called Proof of Power which is a 50% PoW/50% PoS algorithm that solves theoretical weaknesses in other PoS systems (Nothing at Stake problem for example) and is provably immune to 51% hash attacks. With this, Verus uses the new hash algorithm, VerusHash 2.0. VerusHash 2.0 is designed to better equalize mining across all hardware platforms, while favoring the latest CPUs over older types, which is also one defense against the centralizing potential of botnets. Unlike past efforts to equalize hardware hash-rates across different hardware types, VerusHash 2.0 explicitly enables CPUs to gain even more power relative to GPUs and FPGAs, enabling the most decentralizing hardware, CPUs (due to their virtually complete market penetration), to stay relevant as miners for the indefinite future. As for anonymity, Verus is not a "forced private", allowing for both transparent and shielded (private) transactions...and private messages as well"

If other projects can learn from this and adopt a similar approach or continue to innovate with new ideas, it could mean an end to all the doom and gloom predictions that CPU and GPU mining are dead, offering a much needed reprieve and an alternative to miners who have been faced with the difficult decision of either pulling the plug and shutting down shop or breaking down their rigs to sell off parts and buy new, more expensive hardware…and in so doing present an overall unprecedented level of decentralization not yet seen in cryptocurrency.
Technological advancements led us to the world of secure digital currencies and the progress being made with hardware efficiencies is indisputably beneficial to us all. ASICs and FPGAs aren’t inherently bad, and there are ways in which they could be made more affordable and available for mass distribution. More than anything, it is important that we work together as communities to find solutions that can benefit us all for the long term.

In an ever changing world where it may be easy to lose sight of the real accomplishments that brought us to this point one thing is certain, cryptocurrency is here to stay and the projects that are doing something to solve the current problems in the proof of work consensus mechanism will be the ones that lead us toward our collective vision of a better world- not just for the world of crypto but for each and every one of us.

Bitcoin is the fake Skycoin

Satoshi Nakamoto said that biggest flaw in Bitcoin network are miners. That's because consensus algorithm, TX hash rate is dependent on miners calculation. Basically, we are consuming a lot of electricity to gather multiple tx in a block, in order to 3 Chinese mining pools can smash that block and take the Bitcoin reward. And if is not enough, the mining pools can inject fake tx in the network to clog it, so TX fees for us (peasants) will go higher.
  1. Why we are using hardware and electricity to create one block?
  2. Why Consensus algorithm is dependent on a new block creation?
  3. Where is the new Internet we all wanted back in 2009-2010 where millions of computer would be the network ?
https://medium.com/@Skycoinproject/cyberbalkanization-and-the-future-of-the-internets-f03f2b590c39
A) Skycoin is the bigger brother of Bitcoin. Early developers of Bitcoin knew that Miners will control the Bitcoin network in the future, so a part of them started to research a new Consensus Algorithm called Obeliskhttps://www.skycoin.net/blog/posts/obelisk-the-skycoin-consensus-algorithm/
B) Skycoin resolved 51% attack, sybil attack, has 0 TX fee, 1-2 sec for a tx , and is private. But the most important thing.
Skycoin is the only crypto out there who fixed the problem of volatility of a cryptocurrency. What's that ? Imagine if price of Skycoin goes higher and higher, peasants will ''HoDL'' it, so the term ''currency '' is lost. Why someone would spend an asset that goes higher and higher?
B1) One Skycoin kept in the wallet is creating non-stop a second currency called CoinHour. 1SKY is creating 24 CoinHours per day and so on. Coinhour is backed by bandwidth => Skywire(Software Defined Network) is the New Internet that gives Skycoin a real value, a commodity level value. https://www.youtube.com/watch?v=-CbSdVIwr8E
B2) In this ecosystem Skycoin behaves like an equity and CoinHour is the real currency. For example Skycoin Price can reach 1 million and the price of Coinhour is independent, its equilibrium is reached by supply and demand of the market https://explorer.skycoin.net/app/blocks/1
C) Ethereum has a buggy prog language and all shitcoins are on Ethereum Blockchain (Database) with only 30 tx/s. Why would someone would gather all the data on ONE Database?!
C1) Skycoin created CX ( first deterministic cryptographic prog language) https://www.skycoin.net/blog/posts/cx-overview/
C2) Skycoin created Fiber https://www.skycoin.net/fibe ( basically you can create your own blockchain with 300-3000 tx/s, private or public , with hardware customization ( law firms, government entities and so on as early adopters)
D) Skywire is the New Internet built at the Hardware and Software level
-Skywire is hardware agnostic
-Skywire has its DYI Antennas
- Skywire has FPGA boards
-Skyiwire has 10k nodes online ( more than TOR)

TLDR: one neighbor is rendering a movie. He wants 1 TB/ s. He will pay CoinHour to his neighbors to borrow bandwidth capacity of their sky clusters and antennas.

Will crypto mining kill polar bears?

Bitcoin mining uses as much electricity as a small country. Many people hate it for this reason, its one of the more popular arguments against crypto currencies. Will crypto mining kill polar bears? I think not. I think it will help save polar bears. "Bear" with me.
Germany produces a significant part of its electricity from renewable energy: wind and solar. As we all know, these sources are intermittent and seasonal, as is demand. When the share of renewable energy in the overall energy mix becomes large enough, the result is inevitable: temporary and seasonal overcapacity. This isnt just theoretical, energy prices in germany and the UK where effectively negative last Christmas: http://www.businessinsider.com/renewable-power-germany-negative-electricity-cost-2017-12//?r=AU&IR=T
As explained in the above article, this isnt a rare freak occurrence, its expected and this will have to be become much more common if as a society, we want to transition away from fossil fuels. Because to do that we need (much) more renewable energy sources. A study I saw for Germany calculated they needed at least 89% more capacity, just to handle peak loads. But that also implies an incredible amount of overcapacity when demand isnt anywhere near peak, or when supply is above average due to favorable weather. Storing excess renewable electricity, in most places is very expensive and inefficient. So much so that its rarely even done. This is a major problem. Wind turbines are therefore feathered, solar panels turned off, excess electricity dumped in giant electrical heaters, offered for free or even offered at negative prices. Renewable energy may have become cheaper than other forms per KWH, but thats only if when you can sell all of your production. And its only true if the consumption occurs near the renewable energy source and not 100s or 1000s of kilometers further. Building capacity that can only be used 50% or even 10% of the time, or building infrastructure to store surplus electricity is still very expensive, as is transporting renewable energy over long distances.
I know what you're thinking. Mining wont help here, because mining intermittently is something that seems crazy today; miners keep their expensive machines on 24/7. But thats only because today, the overall cost structure of a (bitcoin) miner is heavily tilted towards hardware depreciation. Particularly for anyone paying retail prices for mining asics. This will change completely, because of two related reasons:
1) mining efficiency improvements will taper off.
Mining asics have been progressing extremely rapidly, from being based on CPUs and FPGA's, to using 20 year old obsolete 180nm process technology in the first asics, to state of the art 16nm chips today. This has resulted in at least a million fold improvement in efficiency in just a few years, which in turn lead to hardware investments that needed to be recovered in a few months or even weeks (!) before they were obsolete. Opportunity cost has been so high, that miners have literally chartered 747s to transport new mining equipment from the manufacturer in China to their datacenters in the US.
This cant and wont last. 12nm and 7nm asics are about to be produced, or are being produced now. It doesnt get better than that today, and it wont for many years to come. Moore's law is often cited to show efficiency will keep going up. That may be true, but until now the giant leaps we have seen had nothing to do with moore's law, which "only" predicts a doubling every 18 months. Moore's law is also hitting a brick wall (you cant scale transistors smaller than atoms), and only states that transistor density increases. Not that chips become more efficient or faster, which increasingly is no longer happening (new cpu's are getting more cores, but run at comparable speeds and comparable power consumption to previous generations).
What all this means is that these upcoming state of the art mining asics will remain competitive for many years, at least 3, possibly more than 5 years, and thus can be used and written off over that many years. But they will still consume electricity during all those years, shifting the overall costs from hardware to electricity.
2) Mining is still too profitable (for anyone making their own asics) and mining hardware is therefore still too expensive (for everyone else)
Miner hardware production rate simply hasnt yet been able to keep up with demand and soaring bitcoin prices. This leads to artificially low mining difficulty, making mining operationally profitable even with expensive electricity, and this also leads to exuberant hardware profit margins. You can see this easily, just look at the difficulty of bitcoin. When the price dropped by 70%, did you see a corresponding drop in difficulty? No, no drop at all, it just keeps growing exponentially. That only makes sense because we are not yet near saturation, or near marginal electricity costs for bitmain & Co. Its not worth it yet for them to turn off their miners. Its not even worth it yet for residential miners. Another piece of evidence for this, is bitmains estimated $4 billion profit. But mining is a zero sum game, over time, market forces will drive hardware prices and the mining itself to become only marginally profitable. We're clearly not close to that -yet. You might think so as a private miner, but thats only because you overpaid for your hardware.
Lets look at todays situation to get an idea. An Antminer S9 retails for $2300 and uses ~1300W at the wall. If you write off the hardware over a year, electricity and hardware costs balance out at an electricity price of $0.2/KWH. Anything below that, and hardware becomes the major cost. But how will that evolve?
As difficulty keeps going up, bitcoin mining revenue per asic will decline proportionally, until demand for mining asics will eventually taper off. To counter that, prices of asics will be lowered until they approach marginal production costs, which by my estimate is closer to $200 than $2000. Let say a 1300W S9 equivalent at that point gets sold at $400 leaving bitmain a healthy profit margin; that would mean each year a miner would spend 5x more on electricity than on hardware. Hardware will remain competitive for more than a single year though. Say you write it off over 3 years, now you're spending 15x more on electricity than on hardware. Intermittent mining like 50% of the time, but with free or virtually free electricity will become economical long before that.
By now, I will hopefully have convinced you of the viability of mining with intermittent excess renewable energy; intermittent mining with renewable energy will not only become viable, it will become the only way to do it profitably. Renewable energy at the source is already cheaper than any carbon burning source. Even in Quatar, they install solar plants because its cheaper than burning their own gas. Its transporting and storing the electricity that usually is the problem. Gas can easily be transported and stored. Wind and solar energy can not. And thats a massive problem for the industry. But mining doesnt need either. You can mine pretty much anywhere and anytime. All you need besides electricity, is a few containers and an internet connection for a solar plant or wind farm to monetize excess energy.
Moreover, mining is a zero sum game, a race to the bottom. As long as its profitable for green energy providers to deploy more hardware (which will be true as long as they can at least recover their hardware investment), difficulty will go up. Until it becomes unprofitable for anyone who has to pay for his electricity. No one gives oil, coal or gas away for free, so anyone depending on those sources of electricity, can not remain competitive. If bitcoin price were to go up so much, that there isnt enough renewable electricity production in the world to accommodate the hashrate, bitcoin miners will simply install more solar and wind farms. Not because of their ecological awareness, but because it makes the most financial sense. And during peak demand periods, why wouldnt they turn off the miners and sell their electricity to the grid for a premium?
Basically crypto mining would fund renewable energy development, and solve the exact problem laid out in the article linked above: provide overcapacity of renewable energy to handle grid peak loads, without needing any government funding or taxation on carbon based sources, without needing expensive and very inefficient energy storage. From the perspective of a green energy producer, energy storage, like a battery or hydrogen production, is just an expensive and intermediate step between producing electricity and getting paid for that electricity. Crypto mining will do the same thing, converting excess electricity in to cash, only much more efficiently.
TL:DR, deploying more renewable electricity overcapacity is both very expensive and very necessary if we want to save polar bears. Financing for these large scale green energy projects will either have to come from tax payer money to store or subsidise the largely unused excess electricity, or it will come from crypto mining. Market forces will drive crypto mining to use the cheapest energy. Renewable energy already is cheaper per KWH than carbon based power, and nothing is cheaper than excess and thus free (or negative value) renewable energy. Bitcoin mining's carbon foot print will therefore become ~zero. If you take in to account the effect of financing and subsidizing large scale renewable energy development that can also be used to supply the grid during peak demand periods, its carbon footprint will be hugely negative.
BTW, if you wonder what Blockchains LLC is going to do with 61K acres near Tesla's factory; my guess is solar plants and crypto mining. Expect to see renewable energy development and crypto mining to merge in to one single industry. Check out envion to get a glimpse of this future. Im not endorsing their token as an investment, I havent researched it at all, but the market they are going after is a very real one and its about to explode.
