Paper Wallet Vanity addresses.

EDIT 2/21/2020. I am no longer offering the service described below as I no longer have access to the necessary hardware.
~~~~~~~~~~
Hey all,
I have recently been messing around with vanity addresses for paper wallets. After a little tinkering I got the system working well and can generate wallets up to a certain complexity quite reliably.
I've been able to generate wallets like this one: 1Bitcoinjqekek8HwmT8Cp8ojH9b7Quhzi
This one: 1Satoshi3A43v3Jk9MpfJPUDrWadFUUP6
And this one: 1Genesisud7wjt8Lkto75ANupmviwC2wpW
I personally haven't been using paper wallets for cold storage until now, but with the value of BSV going up and also having read the following paper about the possibility (albeit very small) of compromise of private keys in HD wallets, that for the BSV I intend to sit on long term, it's probably not the worst idea ever to use a paper wallet for that. But hey, it would be nice if those addresses were a bit more recognizable than a random address, am I right? :)
In going through this exercise, I happened to notice that there are services out there that will generate these kinds of addresses, but they seem overly expensive!
e.g., At vanity.coin.dance they want 1 BTC(!!) to generate an address starting with "Satoshi" e.g., like the "1Satoshi3A43v3Jk9MpfJPUDrWadFUUP6" I generated above. That's day-light robbery!!
Furthermore, the above service treats split key generation (which seems necessary for security when having a third party generate the wallet) as an "advanced" feature only. Imagine paying 1 BTC for an address only to have the private key compromised! (Seems almost negligent).
So anyway, whilst I have this system set up and working, I was thinking I could extend a temporary offer to anyone who is interested in getting a vanity address (or addresses) for paper wallet cold storage.
So all that said, the procedure, following the secure split key approach, would be as follows.
  1. You would go to bitaddress.org and download a local copy of the web site (and validate it against provided signatures).
  2. Run that downloaded copy of web site on an off-line system.
  3. Click the Vanity Wallet Tab.
  4. Click the "Generate" button in Step 1.
  5. Copy the public key from Step 1 and PM me with that key (it's quite long so copy/paste is the way to go). Also indicate in the PM the address prefix that you want (can't include invalid characters; I will tell you if you included any). Be sure to keep a copy of the private key from Step 1 (or keep the web page open). If you lose this key the whole process will be for nothing. Do not lose (or compromise) it (and definitely do not PM it to me!).
  6. Send payment (as per the schedule below) to 1Satoshi3A43v3Jk9MpfJPUDrWadFUUP6 and PM me the TxID.
  7. When I receive payment, I will generate a partial private key that you need for Step 2 in the bitaddress.org page.
  8. You take the partial private key that you generated in Step 1 (that you keep secure and never shared with anyone) and paste it into the first box in Step 2 in the Bitaddress.org page (that you are still running locally and off-line).
  9. Finally, you paste the partial private key that I PM you back, into the text box where it says "Enter Pool Part Private Key (from Vanity Pool):" (Note: PMing this partial private key is fine; so long as you keep your partial private key secure (from Step 1), the process is still secure; the process is intended to work this way).
  10. Click "Calculate Vanity Wallet" et viola! A wallet will be produced that meets your prefix requirement and is 100% secure since the partial private key that you generated in Step 1 never left your control.
What you do with your new shiny address from that point on-wards is your prerogative, the same as any other paper wallet that you produce. Our deal is done.
The pricing schedule for this (temporary) service is as follows:
  1. 3 Characters (e.g.,) 1BSVxxxx....xxx 0.01 BSV.
  2. 4 Characters (e.g.,) 1Coinxxx....xxx 0.02 BSV.
  3. 5 Characters (e.g.,) 1Coinsxx....xxx 0.04 BSV.
  4. 6 Characters (e.g.,) 1BuyBSVx....xxx 0.1 BSV.
  5. 7 Characters (e.g.,) 1Satoshi....xxx 0.75 BSV1.
(Footnote 1: Turns out most 7 character combinations are pretty hard to generate and may take quite a while to generate. The prefix "1Bitcoin", however, is not as hard (higher chance of generating), and I can do that one for 0.25 BSV).
(Note: I can't guarantee that I can deliver anything longer than 7 characters, hence there is no price for this).
(Note: The reason for the steep increase in price as a function of number of prefix characters is the time it takes to generate the addresses as they become exponentially more complex and the fact the process is non deterministic).
Compare the above price for a 1Satoshi... address (0.75BSV) to vanity.coin.dance (1BTC!!!) and hopefully you'll see that I'm being pretty reasonable with this, though do note that the "1Satoshi" prefix, specifically, is a hard one to generate and I may not be able to do it unless you are willing to wait a while.
Anyway, I'm not sure if anyone will be interested in this, and you'll have to trust me as someone who has been in this sub since the total membership was only in double digits, that I'm not a fly by night scammer who is going to take your payment and run! To that end I advise that I have made posts in this sub with direct reference to my Australian based registered business that accepts BSV as payment, so it's not hard to track me down. If you go back far enough you'll also see that I was involved in running a Bitstagram competition and came good with the BSV prize in that case. That said, a small amount of trust will be required if this is going to work out. Test me with one of the cheaper options first, if you have doubts.
Terms and Conditions
  1. Any PM received with an "order" is an offer by you to purchase a vanity address. It's not binding until I accept the offer in writing (by PM).
  2. All "orders" will be processed in the order they are received; I will guarantee a 48 hour turn around for everything up to 6 characters and 1681 hours (7 days) for 7 characters. In reality most will be processed much quicker, but I have to cover my ass! If I get too many orders (unlikely!!) I reserve the right to reject any that I cannot meet in a timely manner (any payments that have been made will be refunded to the specified address, less any BSV Tx fees).
  3. This offer is on the table until I withdraw it. I may withdraw it at any time by making a follow up post to this sub edit to this post.
  4. The address that is generated is the address that you get and that is final. If there is something in the address that you don't like (like a random swear word; albeit very unlikely) we can discuss a discounted rate to have a second try at it. (I'd rather you go home happy, if possible).
  5. If there is some address that I cannot generate in the above guaranteed time frames (some are harder to produce than others), I will let you know by PM and refund your entire purchase price.
  6. The entire risk of the use of the generated vanity address lies with you. (I recommend you test it with a small amount and make sure you can withdraw it, before loading it up for real).
(T&C Footnote 1: Some 7 character combinations can take a long time to find (e.g., "1Satoshi") and may take up to two weeks or more! I reserve the right to not even attempt to generate any specific combination that could adversely affect my ability to turn it around in a reasonably timely manner. In that case you can choose a different prefix or I will refund your money, if at that stage you had already paid). For any potential prefix I can check the estimated time to generate and report back on whether it's reasonable, before we agree to go ahead.)
ps/ Here are two three addresses that I generated showing that funds are able to be deposited and withdrawn successfully.
https://blockchair.com/bitcoin-sv/address/1Satoshi3A43v3Jk9MpfJPUDrWadFUUP6
https://blockchair.com/bitcoin-sv/address/1Bitcoinjqekek8HwmT8Cp8ojH9b7Quhzi
https://blockchair.com/bitcoin-sv/address/1BuyBSVMHGx6dSTpLMhALXvEPVEDMStxoR
Both addresses accepted funds and both allowed the BSV to be successfully swept (in this case I used Simply Cash to deposit and sweep).

For Beginners: Vanity addresses. Explaining what vanity addresses are and how you can set up your own address

For Beginners: Vanity addresses. Explaining what vanity addresses are and how you can set up your own address

https://preview.redd.it/16hk9v71y1v11.png?width=2970&format=png&auto=webp&s=aea305e2f81d5280de5c24680af6b93cd09e1486
When accessing or setting up your own Bitcoin wallet, you may notice that it just ends up being a bunch of numbers and letters that have no relevance to you or anything involved with you. What if you had the ability, though, to personalize that Bitcoin address so that it wasn’t just another random string of numbers and letter? Well, that’s exactly what vanity addresses are used for, giving you the opportunity to create a Bitcoin wallet which contains certain starting letters that spell out words like your name or brand. Let’s discuss these vanity addresses some more and learn how you can make your own personalized address.
This is not financial investment advice. This article will explain what vanity addresses are and how you can make your own.

Terminology

Bitcoin Wallet: A Bitcoin wallet is a software program where Bitcoins are stored. To be technically accurate, Bitcoins are not stored anywhere; there is a private key (secret number) for every Bitcoin address that is saved in the Bitcoin wallet of the person who owns the balance. Bitcoin wallets facilitate sending and receiving Bitcoins and gives ownership of the Bitcoin balance to the user.
Wallet Address: A Bitcoin wallet address is similar to a bank account number. It’s a unique 26-35 digit combination of letters and numbers and it looks something like this: 1ExAmpLe0FaBiTco1NADr3sSV5tsGaMF6hd
You can share your Bitcoin wallet address with others. With this, they will be able to send you Bitcoin.
Public Key: A cryptographic code that allows a user to receive cryptocurrencies into his or her account. The public key coupled with the private key are significant tools required to ensure the security of the crypto economy.

Familiarize yourself with these key terms in order to better understand how vanity addresses work.

What’s A Vanity Address?

To put simply, a vanity address is a Bitcoin address with certain starting letters that spell out words such as your name or your brand. This can make your own wallet stand out when receiving or sending Bitcoin, as it can tie in your name or any other word you might want as part of your Bitcoin wallet address. Think of your wallet address as your bank number which you give or show to people so that they can send you cryptocurrencies.
Currently, most - if not all - Bitcoin addresses are just made up of random numbers and letters. Getting a vanity address will definitely make you stand out and give your wallet a unique aspect. Here’s an example of what a basic vanity address would look like:

1googLemzFVj8ALj6mfBsbifRoD4miY36v

A vanity address is essentially a personalized bitcoin address. Most - if not all - Bitcoin wallet addresses are just a string of random letters and numbers, so getting a vanity address gives your wallet a unique aspect.

How Can I Make My Own?

There are two methods to create your own vanity address. The first way is to do it yourself, which is probably the most secure way as nobody can see the private key and public key pair. This does involve knowing a little bit of computing and downloading the correct software. You can then choose how much of your processing power you wish to dedicate to the process, but be aware that dedicating a large proportion of your CPU can make the program crash.
The other method - which might not be as secure - is to go onto a pool such as bitcoinvanitygen.com where you can outsource the work to Bitcoin vanity address miners. These miners dedicate their CPU & GPU power to finding the address you want and send it to you either via email or in the post (if you are paying for it). Although this is a quick process, there is the risk that miners could hold onto the private key that generated the address and use it at some point in the future to hack your funds and steal the millions your vanity address has stored in it.

To get a vanity address you can either make you own, which is the most secure way, or outsource it to vanity address miners.

Conclusion

When the world of cryptocurrency begins to get a bit boring, vanity addresses introduce a unique and even creative aspect to the process of sending and receiving cryptocurrencies. If you ever want to spice things up or make your address stand out, you can always get a vanity address to do so. Although it does take a significant amount of computing power, generating these addresses can make your overall experience much more personalized and allow you to stand out among other wallets.

New Bitcoin Market, New Use For ASICs

Just like ASICs can be taken out of the general hashing pool to generate vanity addresses, perhaps they can also be taken out to process unconfirmed transactions when the rest of the miners ignore their lack of fees.
Lets say the transaction volume increases so that more and more feeless transactions begin to hang around unconfirmed when we reach the 1M block size. Those transactions are in limbo, filling up nodes RAM until someone comes along and puts it in a block. The only way to get them out of the memory pool is to confirm them or reboot the entire network at the same exact time.
Enter Second Chance Mining Company TM. For a bounty/fee, they will take a second look at your transaction and throw their available hashrate at your transactions to include them in the block. Their mining code has the ability to select TXs you identify, or any custom set of TXs and work on solving the hash.
Note: This is just an idea and not a real, functioning company.

Preventing double-spends is an "embarrassingly parallel" massive search problem - like Google, [email protected], [email protected], or PrimeGrid. BUIP024 "address sharding" is similar to Google's MapReduce & Berkeley's BOINC grid computing - "divide-and-conquer" providing unlimited on-chain scaling for Bitcoin.

TL;DR: Like all other successful projects involving "embarrassingly parallel" search problems in massive search spaces, Bitcoin can and should - and inevitably will - move to a distributed computing paradigm based on successful "sharding" architectures such as Google Search (based on Google's MapReduce algorithm), or [email protected], [email protected], or PrimeGrid (based on Berkeley's BOINC grid computing architecture) - which use simple mathematical "decompose" and "recompose" operations to break big problems into tiny pieces, providing virtually unlimited scaling (plus fault tolerance) at the logical / software level, on top of possibly severely limited (and faulty) resources at the physical / hardware level.
The discredited "heavy" (and over-complicated) design philosophy of centralized "legacy" dev teams such as Core / Blockstream (requiring every single node to download, store and verify the massively growing blockchain, and pinning their hopes on non-existent off-chain vaporware such as the so-called "Lightning Network" which has no mathematical definition and is missing crucial components such as decentralized routing) is doomed to failure, and will be out-competed by simpler on-chain "lightweight" distributed approaches such as distributed trustless Merkle trees or BUIP024's "Address Sharding" emerging from independent devs such as u/thezerg1 (involved with Bitcoin Unlimited).
No one in their right mind would expect Google's vast search engine to fit entirely on a Raspberry Pi behind a crappy Internet connection - and no one in their right mind should expect Bitcoin's vast financial network to fit entirely on a Raspberry Pi behind a crappy Internet connection either.
Any "normal" (ie, competent) company with $76 million to spend could provide virtually unlimited on-chain scaling for Bitcoin in a matter of months - simply by working with devs who would just go ahead and apply the existing obvious mature successful tried-and-true "recipes" for solving "embarrassingly parallel" search problems in massive search spaces, based on standard DISTRIBUTED COMPUTING approaches like Google Search (based on Google's MapReduce algorithm), or [email protected], [email protected], or PrimeGrid (based on Berkeley's BOINC grid computing architecture). The fact that Blockstream / Core devs refuse to consider any standard DISTRIBUTED COMPUTING approaches just proves that they're "embarrassingly stupid" - and the only way Bitcoin will succeed is by routing around their damage.
Proven, mature sharding architectures like the ones powering Google Search, [email protected], [email protected], or PrimeGrid will allow Bitcoin to achieve virtually unlimited on-chain scaling, with minimal disruption to the existing Bitcoin network topology and mining and wallet software.
Longer Summary:
People who argue that "Bitcoin can't scale" - because it involves major physical / hardware requirements (lots of processing power, upload bandwidth, storage space) - are at best simply misinformed or incompetent - or at worst outright lying to you.
Bitcoin mainly involves searching the blockchain to prevent double-spends - and so it is similar to many other projects involving "embarrassingly parallel" searching in massive search spaces - like Google Search, [email protected], [email protected], or PrimeGrid.
But there's a big difference between those long-running wildly successful massively distributed infinitely scalable parallel computing projects, and Bitcoin.
Those other projects do their data storage and processing across a distributed network. But Bitcoin (under the misguided "leadership" of Core / Blockstream devs) instists on a fatally flawed design philosophy where every individual node must be able to download, store and verify the system's entire data structure. And it's even wore than that - they want to let the least powerful nodes in the system dictate the resource requirements for everyone else.
Meanwhile, those other projects are all based on some kind of "distributed computing" involving "sharding". They achieve massive scaling by adding a virtually unlimited (and fault-tolerant) logical / software layer on top of the underlying resource-constrained / limited physical / hardware layer - using approaches like Google's MapReduce algorithm or Berkeley's Open Infrastructure for Network Computing (BOINC) grid computing architecture.
This shows that it is a fundamental error to continue insisting on viewing an individual Bitcoin "node" as the fundamental "unit" of the Bitcoin network. Coordinated distributed pools already exist for mining the blockchain - and eventually coordinated distributed trustless architectures will also exist for verifying and querying it. Any architecture or design philosophy where a single "node" is expected to be forever responsible for storing or verifying the entire blockchain is the wrong approach, and is doomed to failure.
The most well-known example of this doomed approach is Blockstream / Core's "roadmap" - which is based on two disastrously erroneous design requirements:
  • Core / Blockstream erroneously insist that the entire blockchain must always be downloadable, storable and verifiable on a single node, as dictated by the least powerful nodes in the system (eg, u/bitusher in Costa Rica), or u/Luke-Jr in the underserved backwoods of Florida); and
  • Core / Blockstream support convoluted, incomplete off-chain scaling approaches such as the so-called "Lightning Network" - which lacks a mathematical foundation, and also has some serious gaps (eg, no solution for decentralized routing).
Instead, the future of Bitcoin will inevitably be based on unlimited on-chain scaling, where all of Bitcoin's existing algorithms and data structures and networking are essentially preserved unchanged / as-is - but they are distributed at the logical / software level using sharding approaches such as u/thezerg1's BUIP024 or distributed trustless Merkle trees.
These kinds of sharding architectures will allow individual nodes to use a minimum of physical resources to access a maximum of logical storage and processing resources across a distributed network with virtually unlimited on-chain scaling - where every node will be able to use and verify the entire blockchain without having to download and store the whole thing - just like Google Search, [email protected], [email protected], or PrimeGrid and other successful distributed sharding-based projects have already been successfully doing for years.
Details:
Sharding, which has been so successful in many other areas, is a topic that keeps resurfacing in various shapes and forms among independent Bitcoin developers.
The highly successful track record of sharding architectures on other projects involving "embarrassingly parallel" massive search problems (harnessing resource-constrained machines at the physical level into a distributed network at the logical level, in order to provide fault tolerance and virtually unlimited scaling searching for web pages, interstellar radio signals, protein sequences, or prime numbers in massive search spaces up to hundreds of terabytes in size) provides convincing evidence that sharding architectures will also work for Bitcoin (which also requires virtually unlimited on-chain scaling, searching the ever-expanding blockchain for previous "spends" from an existing address, before appending a new transaction from this address to the blockchain).
Below are some links involving proposals for sharding Bitcoin, plus more discussion and related examples.

https://np.reddit.com/btc/comments/4su1gf/braiding_the_blockchain_32_min_qa_we_cant_remove/
Some kind of sharding - perhaps based on address sharding as in BUIP024, or based on distributed trustless Merkle trees as proposed earlier by u/thezerg1 - is very likely to turn out to be the simplest, and safest approach towards massive on-chain scaling.
A thought experiment showing that we already have most of the ingredients for a kind of simplistic "instant sharding"
A simplistic thought experiment can be used to illustrate how easy it could be to do sharding - with almost no changes to the existing Bitcoin system.
Recall that Bitcoin addresses and keys are composed from an alphabet of 58 characters. So, in this simplified thought experiment, we will outline a way to add a kind of "instant sharding" within the existing system - by using the last character of each address in order to assign that address to one of 58 shards.
(Maybe you can already see where this is going...)
Similar to vanity address generation, a user who wants to receive Bitcoins would be required to generate 58 different receiving addresses (each ending with a different character) - and, similarly, miners could be required to pick one of the 58 shards to mine on.
Then, when a user wanted to send money, they would have to look at the last character of their "send from" address - and also select a "send to" address ending in the same character - and presto! we already have a kind of simplistic "instant sharding". (And note that this part of the thought experiment would require only the "softest" kind of soft fork: indeed, we haven't changed any of the code at all, but instead we simply adopted a new convention by agreement, while using the existing code.)
Of course, this simplistic "instant sharding" example would still need a few more features in order to be complete - but they'd all be fairly straightforward to provide:
  • A transaction can actually send from multiple addresses, to multiple addresses - so the approach of simply looking at the final character of a single (receive) address would not be enough to instantly assign a transaction to a particular shard. But a slightly more sophisticated decision criterion could easily be developed - and computed using code - to assign every transaction to a particular shard, based on the "from" and "to" addresses in the transaction. The basic concept from the "simplistic" example would remain the same, sharding the network based on some characteristic of transactions.
  • If we had 58 shards, then the mining reward would have to be decreased to 1/58 of what it currently is - and also the mining hash power on each of the shards would end up being roughly 1/58 of what it is now. In general, many people might agree that decreased mining rewards would actually be a good thing (spreading out mining rewards among more people, instead of the current problems where mining is done by about 8 entities). Also, network hashing power has been growing insanely for years, so we probably have way more than enough needed to secure the network - after all, Bitcoin was secure back when network hash power was 1/58 of what it is now.
  • This simplistic example does not handle cases where you need to do "cross-shard" transactions. But it should be feasible to implement such a thing. The various proposals from u/thezerg1 such as BUIP024 do deal with "cross-shard" transactions.
(Also, the fact that a simplified address-based sharding mechanics can be outlined in just a few paragraphs as shown here suggests that this might be "simple and understandable enough to actually work" - unlike something such as the so-called "Lightning Network", which is actually just a catchy-sounding name with no clearly defined mechanics or mathematics behind it.)
Addresses are plentiful, and can be generated locally, and you can generate addresses satisfying a certain pattern (eg ending in a certain character) the same way people can already generate vanity addresses. So imposing a "convention" where the "send" and "receive" address would have to end in the same character (and where the miner has to only mine transactions in that shard) - would be easy to understand and do.
Similarly, the earlier solution proposed by u/thezerg1, involving distributed trustless Merkle trees, is easy to understand: you'd just be distributing the Merkle tree across multiple nodes, while still preserving its immutablity guarantees.
Such approaches don't really change much about the actual system itself. They preserve the existing system, and just split its data structures into multiple pieces, distributed across the network. As long as we have the appropriate operators for decomposing and recomposing the pieces, then everything should work the same - but more efficiently, with unlimited on-chain scaling, and much lower resource requirements.
The examples below show how these kinds of "sharding" approaches have already been implemented successfully in many other systems.
Massive search is already efficiently performed with virtually unlimited scaling using divide-and-conquer / decompose-and-recompose approaches such as MapReduce and BOINC.
Every time you do a Google search, you're using Google's MapReduce algorithm to solve an embarrassingly parallel problem.
And distributed computing grids using the Berkeley Open Infrastructure for Network Computing (BOINC) are constantly setting new records searching for protein combinations, prime numbers, or radio signals from possible intelligent life in the universe.
We all use Google to search hundreds of terabytes of data on the web and get results in a fraction of a second - using cheap "commodity boxes" on the server side, and possibly using limited bandwidth on the client side - with fault tolerance to handle crashing servers and dropped connections.
Other examples are [email protected], [email protected] and PrimeGrid - involving searching massive search spaces for protein sequences, interstellar radio signals, or prime numbers hundreds of thousands of digits long. Each of these examples uses sharding to decompose a giant search space into smaller sub-spaces which are searched separately in parallel and then the resulting (sub-)solutions are recomposed to provide the overall search results.
It seems obvious to apply this tactic to Bitcoin - searching the blockchain for existing transactions involving a "send" from an address, before appending a new "send" transaction from that address to the blockchain.
Some people might object that those systems are different from Bitcoin.
But we should remember that preventing double-spends (the main thing that the Bitcoin does) is, after all, an embarrassingly parallel massive search problem - and all of these other systems also involve embarrassingly parallel massive search problems.
The mathematics of Google's MapReduce and Berkeley's BOINC is simple, elegant, powerful - and provably correct.
Google's MapReduce and Berkeley's BOINC have demonstrated that in order to provide massive scaling for efficient searching of massive search spaces, all you need is...
  • an appropriate "decompose" operation,
  • an appropriate "recompose" operation,
  • the necessary coordination mechanisms
...in order to distribute a single problem across multiple, cheap, fault-tolerant processors.
This allows you to decompose the problem into tiny sub-problems, solving each sub-problem to provide a sub-solution, and then recompose the sub-solutions into the overall solution - gaining virtually unlimited scaling and massive efficiency.
The only "hard" part involves analyzing the search space in order to select the appropriate DECOMPOSE and RECOMPOSE operations which guarantee that recomposing the "sub-solutions" obtained by decomposing the original problem is equivalent to the solving the original problem. This essential property could be expressed in "pseudo-code" as follows:
  • (DECOMPOSE ; SUB-SOLVE ; RECOMPOSE) = (SOLVE)
Selecting the appropriate DECOMPOSE and RECOMPOSE operations (and implementing the inter-machine communication coordination) can be somewhat challenging, but it's certainly doable.
In fact, as mentioned already, these things have already been done in many distributed computing systems. So there's hardly any "original work to be done in this case. All we need to focus on now is translating the existing single-processor architecture of Bitcoin to a distributed architecture, adopting the mature, proven, efficient "recipes" provided by the many examples of successful distributed systems already up and running like such as Google Search (based on Google's MapReduce algorithm), or [email protected], [email protected], or PrimeGrid (based on Berkeley's BOINC grid computing architecture).
That's what any "competent" company with $76 million to spend would have done already - simply work with some devs who know how to implement open-source distributed systems, and focus on adapting Bitcoin's particular data structures (merkle trees, hashed chains) to a distributed environment. That's a realistic roadmap that any team of decent programmers with distributed computing experience could easily implement in a few months, and any decent managers could easily manage and roll out on a pre-determined schedule - instead of all these broken promises and missed deadlines and non-existent vaporware and pathetic excuses we've been getting from the incompetent losers and frauds involved with Core / Blockstream.
ASIDE: MapReduce and BOINC are based on math - but the so-called "Lightning Network" is based on wishful thinking involving kludges on top of workarounds on top of hacks - which is how you can tell that LN will never work.
Once you have succeeded in selecting the appropriate mathematical DECOMPOSE and RECOMPOSE operations, you get simple massive scaling - and it's also simple for anyone to verify that these operations are correct - often in about a half-page of math and code.
An example of this kind of elegance and brevity (and provable correctness) involving compositionality can be seen in this YouTube clip by the accomplished mathematician Lucius Greg Meredith presenting some operators for scaling Ethereum - in just a half page of code:
https://youtu.be/uzahKc_ukfM?t=1101
Conversely, if you fail to select the appropriate mathematical DECOMPOSE and RECOMPOSE operations, then you end up with a convoluted mess of wishful thinking - like the "whitepaper" for the so-called "Lightning Network", which is just a cool-sounding name with no actual mathematics behind it.
The LN "whitepaper" is an amateurish, non-mathematical meandering mishmash of 60 pages of "Alice sends Bob" examples involving hacks on top of workarounds on top of kludges - also containing a fatal flaw (a lack of any proposed solution for doing decentralized routing).
The disaster of the so-called "Lightning Network" - involving adding never-ending kludges on top of hacks on top of workarounds (plus all kinds of "timing" dependencies) - is reminiscent of the "epicycles" which were desperately added in a last-ditch attempt to make Ptolemy's "geocentric" system work - based on the incorrect assumption that the Sun revolved around the Earth.
This is how you can tell that the approach of the so-called "Lightning Network" is simply wrong, and it would never work - because it fails to provide appropriate (and simple, and provably correct) mathematical DECOMPOSE and RECOMPOSE operations in less than a single page of math and code.
Meanwhile, sharding approaches based on a DECOMPOSE and RECOMPOSE operation are simple and elegant - and "functional" (ie, they don't involve "procedural" timing dependencies like keeping your node running all the time, or closing out your channel before a certain deadline).
Bitcoin only has 6,000 nodes - but the leading sharding-based projects have over 100,000 nodes, with no financial incentives.
Many of these sharding-based projects have many more nodes than the Bitcoin network.
The Bitcoin network currently has about 6,000 nodes - even though there are financial incentives for running a node (ie, verifying your own Bitcoin balance.
[email protected] and [email protected] each have over 100,000 active users - even though these projects don't provide any financial incentives. This higher number of users might be due in part the the low resource demands required in these BOINC-based projects, which all are based on sharding the data set.
[email protected]
As part of the client-server network architecture, the volunteered machines each receive pieces of a simulation (work units), complete them, and return them to the project's database servers, where the units are compiled into an overall simulation.
In 2007, Guinness World Records recognized [email protected] as the most powerful distributed computing network. As of September 30, 2014, the project has 107,708 active CPU cores and 63,977 active GPUs for a total of 40.190 x86 petaFLOPS (19.282 native petaFLOPS). At the same time, the combined efforts of all distributed computing projects under BOINC totals 7.924 petaFLOPS.
[email protected]
Using distributed computing, [email protected] sends the millions of chunks of data to be analyzed off-site by home computers, and then have those computers report the results. Thus what appears an onerous problem in data analysis is reduced to a reasonable one by aid from a large, Internet-based community of borrowed computer resources.
Observational data are recorded on 2-terabyte SATA hard disk drives at the Arecibo Observatory in Puerto Rico, each holding about 2.5 days of observations, which are then sent to Berkeley. Arecibo does not have a broadband Internet connection, so data must go by postal mail to Berkeley. Once there, it is divided in both time and frequency domains work units of 107 seconds of data, or approximately 0.35 megabytes (350 kilobytes or 350,000 bytes), which overlap in time but not in frequency. These work units are then sent from the [email protected] server over the Internet to personal computers around the world to analyze.
Data is merged into a database using [email protected] computers in Berkeley.
The [email protected] distributed computing software runs either as a screensaver or continuously while a user works, making use of processor time that would otherwise be unused.
Active users: 121,780 (January 2015)
PrimeGrid
PrimeGrid is a distributed computing project for searching for prime numbers of world-record size. It makes use of the Berkeley Open Infrastructure for Network Computing (BOINC) platform.
Active users 8,382 (March 2016)
MapReduce
A MapReduce program is composed of a Map() procedure (method) that performs filtering and sorting (such as sorting students by first name into queues, one queue for each name) and a Reduce() method that performs a summary operation (such as counting the number of students in each queue, yielding name frequencies).
How can we go about developing sharding approaches for Bitcoin?
We have to identify a part of the problem which is in some sense "invariant" or "unchanged" under the operations of DECOMPOSE and RECOMPOSE - and we also have to develop a coordination mechanism which orchestrates the DECOMPOSE and RECOMPOSE operations among the machines.
The simplistic thought experiment above outlined an "instant sharding" approach where we would agree upon a convention where the "send" and "receive" address would have to end in the same character - instantly providing a starting point illustrating some of the mechanics of an actual sharding solution.
BUIP024 involves address sharding and deals with the additional features needed for a complete solution - such as cross-shard transactions.
And distributed trustless Merkle trees would involve storing Merkle trees across a distributed network - which would provide the same guarantees of immutability, while drastically reducing storage requirements.
So how can we apply ideas like MapReduce and BOINC to providing massive on-chain scaling for Bitcoin?
First we have to examine the structure of the problem that we're trying to solve - and we have to try to identify how the problem involves a massive search space which can be decomposed and recomposed.
In the case of Bitcoin, the problem involves:
  • sequentializing (serializing) APPEND operations to a blockchain data structure
  • in such a way as to avoid double-spends
Can we view "preventing Bitcoin double-spends" as a "massive search space problem"?
Yes we can!
Just like Google efficiently searches hundreds of terabytes of web pages for a particular phrase (and [email protected], [email protected], PrimeGrid etc. efficiently search massive search spaces for other patterns), in the case of "preventing Bitcoin double-spends", all we're actually doing is searching a massive seach space (the blockchain) in order to detect a previous "spend" of the same coin(s).
So, let's imagine how a possible future sharding-based architecture of Bitcoin might look.
We can observe that, in all cases of successful sharding solutions involving searching massive search spaces, the entire data structure is never stored / searched on a single machine.
Instead, the DECOMPOSE and RECOMPOSE operations (and the coordination mechanism) a "virtual" layer or grid across multiple machines - allowing the data structure to be distributed across all of them, and allowing users to search across all of them.
This suggests that requiring everyone to store 80 Gigabytes (and growing) of blockchain on their own individual machine should no longer be a long-term design goal for Bitcoin.
Instead, in a sharding environment, the DECOMPOSE and RECOMPOSE operations (and the coordination mechanism) should allow everyone to only store a portion of the blockchain on their machine - while also allowing anyone to search the entire blockchain across everyone's machines.
This might involve something like BUIP024's "address sharding" - or it could involve something like distributed trustless Merkle trees.
In either case, it's easy to see that the basic data structures of the system would remain conceptually unaltered - but in the sharding approaches, these structures would be logically distributed across multiple physical devices, in order to provide virtually unlimited scaling while dramatically reducing resource requirements.
This would be the most "conservative" approach to scaling Bitcoin: leaving the data structures of the system conceptually the same - and just spreading them out more, by adding the appropriately defined mathematical DECOMPOSE and RECOMPOSE operators (used in successful sharding approaches), which can be easily proven to preserve the same properties as the original system.
Conclusion
Bitcoin isn't the only project in the world which is permissionless and distributed.
Other projects (BOINC-based permisionless decentralized [email protected], [email protected], and PrimeGrid - as well as Google's (permissioned centralized) MapReduce-based search engine) have already achieved unlimited scaling by providing simple mathematical DECOMPOSE and RECOMPOSE operations (and coordination mechanisms) to break big problems into smaller pieces - without changing the properties of the problems or solutions. This provides massive scaling while dramatically reducing resource requirements - with several projects attracting over 100,000 nodes, much more than Bitcoin's mere 6,000 nodes - without even offering any of Bitcoin's financial incentives.
Although certain "legacy" Bitcoin development teams such as Blockstream / Core have been neglecting sharding-based scaling approaches to massive on-chain scaling (perhaps because their business models are based on misguided off-chain scaling approaches involving radical changes to Bitcoin's current successful network architecture, or even perhaps because their owners such as AXA and PwC don't want a counterparty-free new asset class to succeed and destroy their debt-based fiat wealth), emerging proposals from independent developers suggest that on-chain scaling for Bitcoin will be based on proven sharding architectures such as MapReduce and BOINC - and so we should pay more attention to these innovative, independent developers who are pursuing this important and promising line of research into providing sharding solutions for virtually unlimited on-chain Bitcoin scaling.

[Not bitcoin] For laughs, I tried out another cryptocurrency (NXT) to see what a "better than bitcoin" is like. It's ... not good at all. Warning: long rant.

A couple of months ago (before I came across /buttcoin) I got curious about whether the underlying tech involved could produce a useful currency if it were detached from the batshit insane "community" that's made bitcoin a laughing stock.
So I grabbed the (then current) NXT client, started it up, and played with it a bit. Then I stopped playing with it because it stayed stuck "downloading blockchain" for a couple hours without making progress. I shelved it and forgot about it until I saw a mention of it this morning.
It prompted me to spin it up one more time to see if it'd improved at all. It hasn't. I knew these altcoins were mostly spawned as pump-and-dump scams, but holy shit, they've really gone off the deep end on this one.
And that's just the client. Then there's the coin itself:
To its credit, the network claims to be processing 179 transactions per hour (2.98 per second), so it's already running almost as fast as BTC's practical top speed. So they've got that going for them at least. I suck at math. The network processes 179 transactions per hour, which is 2.98 transactions per minute, not per second. I guess bitcoin's still the "speed king" at its blazing 3-4 per second speeds.
But yeesh. Talk about a waste of resources. This is just crap. And this is the desired user experience. BTC is the same way, of course, claiming that it's "easy to use". How in hell does anyone expect others to actually use this crap? Apart from not needing to bother with it in order to spend real money, and the fact that there's no incentive to keep a client running (except to avoid the ridiculous startup time), the "UX" is just a total shit show. What's the damned point?
Bleh. Total waste of time this morning. Rant over :)

The Venom of God

So many thoughts come, in my hunger to record the shape of that which ails me.
Memories, imprinted like typewriter keys on the wet, spongy mass of the brain, feel transient, like ancient scrolls or commandments inscribed on crumbling slate, eroded by desert winds in unfathomably ancient ages. The memories of a man, fragmented in time - wet with horror and delusion.
For some reason, softer memories of childhood rise to the surface sometimes, like leaves in a dirty backyard pool, only to become too raw and shamefully unclothed when exposed to the sunlight of a middle aged man’s temperament.
I remember games of Checkers with my great Grandfather, Ildor Hearst, who appears in my mind’s eye as a-kind-of Russian Santa Claus, wirey beard and carven forehead. He was a stern man, and would always be ranting his archaic religious views. Prostheletising the fall of modern Babylon and the age of the Nihilist.
He would play Checkers with me, sharp movements, wooden circles slammed down with impunity. He never let me win. Saw his dominance as a matter of instruction and learning. As I look back nostalgically, sometimes, I yearn for Great Grandfather Ildor’s black and white mentality of good and evil, lightness and darkness... and an over arching confidence in the eventual triumph of mankind. Rather than the bleak reality of the post modernist distopia in which I live.
I recall vividly, after those intense games, once Ildor had imparted his thorny wisdom, I would be granted relaxation and be free to play with my own toys, scattered around my grandparents wooden floor boards; Mutant Ninja Turtles and Transformers, Wonder Woman, Spider Man and He-Man. Mine was always a multicoloured world of complex morality and democratic voices ... all of which ran into muddy paradigms that seemed totally outside the circle of Great Grandad’s moral compass.
These days, as a real estate Agent, I am occasionally gifted limited insights into a checkerboard like world of manipulation and sinister intentions, but mine is to perceive the evil of global finance, and the general unfairness of land ownership and rabid, unchecked capitalism...but with no delusion of an interventionalist God to pull us out of the hole we humans have dug for ourselves.
My name is Vilson Hearst, and I am a Real Estate Agent for Steel City Real Estate in Hexton, Australia.
Perhaps you think yourself free from the real estate game. Perhaps, you are a fool.
Perhaps you are satisfied with your lot in life, making a simple way for yourself, with a mortgage and a family, (if you should be so lucky to afford to get into the housing market at all that is). Then, could be that you are living a student lifestyle, paying rent, constantly paying off another cunning man’s mortgage, or worse still, perhaps you have abandoned the fight, to cower in your parents basement, with the real world slowly closing in on you, as you desperately try to escape into a world of Hollywood movies, video games or creepy pasta.
You are all in the real estate game, wether you like it or not. There is a broader game of capital and estate, which is increasingly complex, and even those like myself who’s job it is to ‘follow the money’ sometimes are completely lost at sea in the Darwinian struggle of the global free market.
Studying finance at Bourkeley University,.. I did my PHD thesis about money and the aquisition of power. I spent a solid year, studying the major players in global banking, watched the Chinese ICBC rise to become the wealthiest banking institution in the world. I tracked the strange and secretive trails of the richest investors, after the terrorist attacks on September 11, watching money transfer around the globe in secret trust funds, private meetings of powerful elites in Shanghai—as the Chinese World Trade Centre “Tower Three” was built, in the image of the destroyed Twin Towers of New York, (which is no coincidence, given it was constructed by the same architecture group; Skidmore Owings and Merril, (who also constructed the replacement One World Trade Centre.))
I studied Wikileaks and other whistleblower organisations. Gained secret documents, and learned of meetings between wealthy individuals; John Fallon, the chief executive of Pearson Education, the company which controls half the worlds schooling institutions— made a private deal in 2015 with Indra Nooyi and Paul Bulcke, Chairman and CEO of Nestle and PepsiCo, the owners of the majority of global food and confectionary. You wonder why our children are so desperately obese.
I was constantly surprised by the familiarity of these billionaires with one another. For instance, you might not know, that Hugh Grant, the CEO of Monsanto, the sinister company who has come to dominate a stronghold on global agriculture, (and who, among more nefarious acts, was responsible for manufacturing the deadly ‘Agent Orange’ poison in Vietnam and causing countless generational mutations).. just happens to be close friends with the CEO of Lockheed Martin, the dominant power in weapons manufacturing and ultimately what people mean when they talk about the ‘military industrial complex’.
Guns don’t kill people. Corporations do. But you knew that already.
Other minutes from meetings by the powerful, would have many questioning what the leaders of certain organisations could possibly have to discuss with each other,... such is the nature of the unheard of D40 meeting in a chateau in Shandong Province; where Barry Lam, chairman and founder of Quanta computers, the name behind the majority of computing technology, was recently in discussion with Carlos Brito, the CEO of InBev; the name behind all the major alcohol players—Ian Read, the CEO of Pfizer, who basically controls the entire legal drug market, Mark Zuckerberg and the CEO Of Alphabet Inc— who own Google and most of the rest of the internet. Now these meetings bare direct relationships with the stock trading happening in the World Trade Centre Tower Three in China. The minutes from these meetings contained discussion both controversial and amazingly nuanced, and the complexity of the global solutions some of these key players in the tech revolution were coming up with would’ve gone over the heads of even the top IQ holders from 98 percent of high schools in the world. Nonetheless, some of the darker plans by these shady monopolies would terrify you, more than you could possibly know.
To understand Australian land ownership, the problem becomes more of a global puzzle.
The figures who own the most land globally, are, the King of Saudi Arabia, The Pope and the Catholic Church, Hugh Grosvenor, Duke of Westminster certainly has a cut, and of course, the Queen of Britain herself, Elizabeth ...(who currently owns about a sixth of the worlds land, some 6.6 Billion Acres, more commonly known as the Commonwealth Realm, (which includes two thirds of Antarctica, Time Square in New York, Canada, New Zealand and of course ... Australia.) These people, i’ve learned, are not particularly interested in the debate around land ownership coming to the forefront of the global conversation, and billionaire media moguls like Rupert Murdoch and Andrew Packer have filled their bank accounts, making it their mission to keep just such subjects off the family dinner table, with distractions like ‘My Kitchen Rules’ and ‘Keeping up with the Kardashians’ filling Australian television channels.
The question of wether anyone owns land in Australia, or if it is in fact all owned by the Queen of England, is a contentious one, particularly when you factor in the confounding elements such as the status of Norfolk Island, which at one time was, on a technicality, not owned by anyone except for the fictitious body ‘The Crown’ (until being taken over by the Australian Capital Territory, in 2015). Then when you consider the original claim of the British that the Australian nation was unoccupied or ‘Terra Nullius’ when Europeans arrived, a truth widely held as fact until the precedent of the Mabo Decision in the Torres Straight islands in 1992. This decision returned some land ownership rights back to certain aristocratic lineages of the native people. However, the paradox leaves a complex and enduring problem for the future of land ownership in Australia and what that exactly entails.
In Hexton, the most rapidly developing city in Australia, corporate billionaires have their stakes in national land ownership, yet meanwhile... National Parks, Botanical Gardens and other public spaces are unapologetically ‘Crown lands’, a fact which is still testified by the names of the spaces; Kings Domain, Queen’s Square, and other titles which clearly and proudly display the heritage of monarchic ownership deeply entrenched within the Australian property market.
Of course, even within the field of Australian National Real Estate, the individual estate agent becomes bogged down even further in matters of local estates, so that these important issues take second stake to the sales and acquisitions of the day.
Steel City Real Estate, the company I work for, is a nation wide brand, but our particular office in Albert Park consists of about nine agents.
I spend most of my time competing with the golden boy of Steel City, Greg Leisdadt. Greg has consistently won the monthly sales targets in our office for over a year. His desk is covered in trophies, awards, and framed certificates adorn the walls behind him.
I’m not sure what words could aptly describe Leisdadt; his wolf-like eyes, both evil and mesmerising. A cannibal grin consisting of Colgate super white teeth, and those gelled locks of amber hair which hang impossibly, like an arch villain over his forehead. Greg oozes saleable confidence which grates my own nervous disposition sufficiently towards constant despair.
The only force which makes the constantly eclipsing day to day victories of Leisdadt bearable to me is Natasha Valuvjdavo. She is the agent who sits on the adjacent table to me in the office.
I confess, for some time, I was profoundly attracted to Natasha, and had to stop myself from gushing and fawning over her. She is a demure, and assertive brunette, her crimson lips could kill a boat full of sailors. Unfortunately, she is engaged to a man named Fred, who is something of a wet blanket, yet I must discard my jealousy and confess that for whatever reason, Natasha seems happy in her domestic life. My only solace in this, being that Greg Leisdadt, the man who has everything, although persistently flirtatious, has never made a dent in Natasha’s self security. She is thankfully not attracted to him.
But now I should refrain from being sidetracked and talk about the subjects which, you, the reader, more likely desire to hear of. For my tale is no idle blathering of romantic ennui, or global conspiracy—but rather the trauma of my profession, does persist— in both being exposed to the ruthless game of money/power, but moreover being haunted by knowledges both gothic and Victorian. For there is no other game in town, where one is more exposed to unwanted or haunted real estate; the devil hounded, and the wished forgotten.
There are the houses that are impossible to sell, because of brutal or public bloody murders that have occurred to the prior occupants. Wether psychological or other, the frequency of those who purchase such forbidden and damned abodes —then in no matter of time, flee and sell at carelessly lower settlement costs, with tales of unhallowed things returned to life, or clanking noises in the basement...why... this simple fact of the real estate market is as common as there is. A story as old as time.
Now perhaps I could spend months repeating the folk lore surrounding that dilapidated and spiritually unsaveable address; that run down, trash infested garden, and collapsing terrace roof of no 13 MacArthur Street.
But this could take a conceivably longer time period, and I shall reserve my energy for the most disturbing and horrific of these preternatural experiences.
Though I should briefly mention Vernon tower, for though this wasn’t the property which near drove me to insanity, it factors too far into the disturbing tapestry of the veiled or hidden real estate scene.
Now, Vernon tower, is an enormous building in South Hexton. Our agency deals more with rentals than with sales of the apartments in that old, and curious piece of architecture. Built as early as 1866, there has always been something profoundly wrong with Vernon towers. Of course, it is me who has to deal with most of the tennants of that foreboding block, for it is the Hearst legacy to be fated just such dull luck.
Thus it is always, I, who takes the phone calls from disgruntled students and drug addicts; Vernon Tower is unprecedentedly cheap, due to its history. Yet the impoverished clientele still have no issue burning my ear off; to complain of strange mechanic noises, or those bizarre phosphorescent green lights. Then there was the girl who tried to sue us, after her seizure from what she claimed to see inside the laundry room. That manner of description I can scarce repeat for its absurdness and high strangeness.
But let me get to the more dreadful incident which frightens me even to recall.
Indeed, it had all begun with that infernal property in Elwood, which I was in terse competition to sell... pitted unwittingly against the undefeated Super-Agent, Greg Leisdadt.
The spectacularly immense mansion on Ormond Road, was once occupied by billionaire Serbian entrapaneur Dimitrije Stojanovic, who I’m told partially drafted the architectural plans for the immense mansion himself, before he had it constructed on the corner of Ormond and Radkin Streets. The nature of the oddities surrounding that place however, extend not from the architectural style of the lot itself, (mind you those odd modernist geometric pylons, stepped piers and sail-like rooves do lend a kind of funereal gothicness to the address.)
However, it was the murder of Stojanovic which caused true fluctuations of interest in the property. Given the public knowledge of the horrendous murder, the property value was incalculably lower than its market worth. It seemed the image of the alleged burglar breaking into Stojanovic’s window, and bludgeoning him to death in the lounge room with a heavy trophy or statue of some kind— somehow grinding his skin off as with multiple teeth, or a spiked club—stayed in the public mind, thanks to Channel 9’s ‘A Current Affair’ and their sensational program about the incident. For interest in the property remained uncharacteristically low. Perhaps the fact that the murderer has yet to be identified or captured by police, nor the murder weapon found, hasn’t helped the matter.
Now, as I have mentioned this was not the first time our staff had dressed up a ‘murder property’. But the truly disturbing elements began to happen during the time the property came under my tenure.
Now, I should proclaim sincerely that I am by no means a superstitious man, I admonish my readers to believe that I was just as skeptical about the soon to be foretold events as you, had I not experienced them myself, I should fiercely doubt my own sanity. I should also divulge a little more information about Dimitrije Stojanovic himself, (the owner of the grand mansion) as the web of intrigue very much seems to hinge on his professional history.
Stojanovic made his billions in Silicon Valley, working in many aspects of the tech industry, investing timely in companies like Facebook and crypto currencies like Bitcoin, when the time was right. in the move to Australia it seems that his ambition was to try out his own company idea in the developing market of Hexton, where the game was not already dominated and over exposed.
With this intent he came out, built his immense mansion in Elwood, Moonsmoth, and immediately started channeling his money into the development of something called .....‘DigiTown’.
Now being neither a tech expert myself, nor expecting such of my audience, I will explain the fundamentals of the ‘DigiTown’ concept in the same manner it was explained to me by Neil Druton, a four eyed nerd with an immense forehead who was one of the developers working for Dimitrije Stojanovic, before he died. I had decided to interview Druton, to get the background on the Stojanovic case to find a more positive angle for investors. I figured if I could distract the buyer from the details of the murder, and big talk the profile of Stojanovic himself, “the prolific entrapaneur”, this might flatter the egos of other wealthy entrapaneurs to buy it out.
Druton told me he had been working for Stojanovic for about six months, mostly at the office Space Dimitrije was renting in Southbank. He described Stojanovic as ruthless, and borderline insane, but nonetheless he spoke of ‘DigiTown’ with respect, a ‘unique’ and ‘brilliant’ project, which would have been at the forefront of the tech industry, if it had ever been finished.
Put in layman’s terms, Druton explained that the project had a great deal in common with Bill Gates plans for a ‘smart city’ but on a more achievable scale.
I could tell Druton was oversimplifying the description for my sake, no doubt parroting Dimitrije’s marketing pitches for investors. But he described it like this; ‘Imagine a kind of augmented portal, with a built infrastructure and virtual architecture planned by white collar professionals, a crypto currency run communal space, overlayed over a modern city space, where your own request portal is linked to different reference cubes; Town Square, Library Cube, Media Station, Entertainment Centre, Eateries, telematics and roads authority, and these all function via the same channels as an actual city.’ ‘So you mean, instead of one social media interface trying to network everything, the actual infrastructure of a city is built out within the media itself?’ I asked. ‘Yeah pretty much’ Druton replied, seeing I had sensed the practical nature, adaptability, and profitability of the software, all over the world. ‘ATMs, shops, business, smart cars and machinery— all worked into the same dual augmented system. Superimposed as a direct collorary.’ It got me thinking paranoid, and I asked Druton earnestly; ‘Do you think if another rogue in the tech industry knew about Stojanovic’s idea, it would have been a groundbreaking idea enough to have killed him over?’ Druton went silent, and sweated a little from his pimpled forehead. I didn’t need to hear him answer the question, it was written all over his shrivelled face.
I spent a good couple of months doing my research on Dimitrije’s mansion. (I would’ve loved to cover up the existence of the current owner of the mansion). Rich heiress Stacey White bought the house, and lived in it for a month before she got spooked— and decided to resell it. I made sure to get the story straight, offering Stacey a hot cup of Bush tea, and asking her precisely what she saw.
Here’s what she told me; ‘I was alone, in that creepy mansion, at night,... and I got a weird feeling. There was a strong wind, and it was dark. The gum tree in the front yard bends a lot in the wind, and sometimes the branches whip against the side of the house. I was just getting used to that noise, but this time it was something different, almost lost in the whistling wind. It was a lower kind of ...moaning. A deep, pained groan. I got up to check I hadn’t left something on in the kitchen. I went to turn on the light switch but the globe burnt out. That’s when it happened. Almost like a mini-earthquake, but there was this strange energy. Then the gas stove just lit up, a green flame. It wasn’t on, but the kitchen was illuminated in a kind of underwater hue. Then—-(Stacey began to gasp and sob)—-then... in the darkness — I saw it!! A green head! Half a Human head, but mangled, half the skull bashed in, shimmering like I was looking through glass. It spoke to me ....in a voice that made the room cold. Just—-(she broke down into tears, suppressing a scream). H—his lips... cold, green lips. Steam coming from his mouth. He said — he said—- ‘Beware the Wagluh’.
As this point she became incommunicable.
I felt an increasing sickness in the ensuing weeks, the cause was unknown, but chiefly matched my mental state. It must’ve been around this time when I first saw the strange rune which had been spray painted on the abandoned building in Elwood. I was doing my rounds, why I should’ve noticed the strange glyph remains beyond my understanding, yet there it was. A curious, green shape, interrupted by a stark arrow and a kind-of ladder shape above it.
I was becoming increasingly stressed and agitated by the competitive sale of Dimitrije’s mansion. My manager Herron Del Ray had been hounding me to make a sale, it had been months since I had successfully got a down payment from a client. Del Ray had threatened redundancy in no uncertain terms, and the stress was beginning to erode my total mental well being.
In conversations with my beautiful colleague Natasha around this time, I found her to be kind, but not particularly helpful. Her advice was that if I was going to beat Leisdadt, I would have to compete with him at his own game. She told me on one particular occasion I should just lie to clients about the gruesome murder in the house, or omit it from the description altogether. This was both against my moral compass, and senseless, for the case was so popular, I felt sure that any potential investor would know of it, to omit it would only anger them.
That same day I got a call from a potential buyer named Greame De Montague. Leisdadt watched me like a hawk as I took the call, giving me a cunning look. The stare flustered my nerves, but choking through the phone I agreed for an inspection with De Montague. He would be the fifth buyer I had spoken to, all four previous investors had abandoned their inquiries when learning more about the murder, or after having seen the contract of sale.
I calmed myself the day of the appointment by speaking soft mantras to myself under my breath. I knew I had to push this client to a final purchase, and my job security depended on it. Greg Leisdadt was leaning against the bronze statue of a Cheetah in our office as I was leaving, mocking me with the words ‘Good luck, Vilson old boy.’
It was a cold autumn day, and brown leaves blew around the streets in gusts of curdled wind.
I had arranged to meet Mr De Montague on Beach Avenue, so that we might walk down to Ormond Street and view the mansion. As an eerie coincidence the corner we agreed to meet was precisely at the point that odd rune was sprayed on the abandoned building in Elwood.
Greame De Montague was standing on the corner as I arrived in my light grey sedan. He was standing in front of the odd rune, as though the symbol itself had somehow marked his presence in an unexplainable yet mystical time stamp. I couldn’t see his car parked anywhere. He was wearing a very curious oufit, particularly for Australia, although the weather was reasonably cool that autumn day. He wore a kind of black velvet robe, cut in the shape ...not unlike an Orthodox Jew’s regalia. It tarried at the bottom into a sort of deep purple cape. On his head he wore a buckled Capotain, and in his hand, a decorated staff. I wondered if his clothing indicated the excesses of vanity of the social media age, or if he was perhaps a foreign prince of some kind.
I stepped out of the car, and approached De Montague with my hand extended. I could see now he had a strange face, with slanted owl-like eyebrows, and a fluffy round beard that gave him an almost koala-bear-shaped head.
Mr De Montague raised his hand and met my embrace, shaking my hand with a firm clasp. ‘It’s lovely to meet you Greame. I have a feeling you are going to love this property.’ ‘Please. Call me Lord De Montague.’ The stern man insisted, ‘I descend from Carpathian royalty, the son of a Duke.’ ‘Very well M’lord.’ I replied, my tone accidentally tinged with irony, ‘Have you come ...very far today?’ I asked trying to distract from my faux pas with a bluff of small talk. I couldn’t help staring at the strange Necklace around De Montague’s neck. It seemed to be made of solid gold, and was comprised of a chain of large charms, each coin depicting deities from Ancient Asian and Mesopotamian religions.
I began walking, unsure what to say but deciding to lead De Montague down towards Ormond Street. There was a terrifying stillness on the street that day. The sun dried grass seemed frozen in time, and the grey sky moaned geriatrically, with the energy of a tired giant trying to fend off the vast abyss of Space.
I noticed that De Montague was not moving, but had instead stopped firmly in his tracks. His face gave off a distinct lack of pathos.
‘Mr Hearst.’ Lord De Montague’s grainy voice echoed; ‘This is the wrong way.’ I turned and looked back at him confused, but De Montague quickly supplanted my curiosity ‘We should walk down Vautier Street. It comes out closer to the property on Ormond.’ By my own calculations, the distance was exactly the same, but as I was in a desperate state of flattery, I decided to humour the strange, old man, though I now questioned wether my client might be an eccentric madman, who merely thought he was born of Royalty, in his delusions.
Nonetheless, I followed De Montague and we wandered down the leafy, terraced streets.
‘Tell me something Mr Hearst’ De Montague began to speculate; ‘Have you ever heard the expression ‘Old Money’?’ I looked at him trying to gage his meaning; ‘Yes, of course.’ I replied. ‘The man who owned this mansion’, De Montague continued in a practiced refrain; ‘It is my understanding he was one of the new breed. Wouldn’t you say? Those who make their fortunes on the gamble— or the changing technologies of the world, but haven’t yet come to fully comprehend the system as it works. As it has always worked.’ ‘I’m afraid I haven’t come to fully appreciate your meaning.’ I replied with honest perplexion. ‘My ancestors were very interested in Asian spirituality’ De Montague continued in a seemingly distracted soliloquy, ‘The De Montagues have migrated for some time you see. Sharing something in common with the Romani people of Europe. I have had ancestors who have lived, over the centuries, in Vietnam, Thailand, Cambodia, Mongolia, Papua New Guinea and the Phillipines. Do you know what is the one thing these vastly different cultures all have in common?’ ‘I do not’ I confessed. ‘Reverence for ones ancestors, and respect for ones elders, and an overwhelming policy of acceptance towards the natural systems that have always existed.’ ‘That’s very interesting’ I replied, gawking about anxiously and wondering where the conversation was leading. ‘I have only more recently come to adapt the principles of the Japanese Shinto religion into my philosophy Mr Hearst. However I think we could all take a page out of that discipline, and it’s superior attitude towards the unknown. You know, in some sense the Shinto practitioners had an almost scientific approach to their spirituality. Certainly, like with the Eastern superstitions, the Shinto perceived a longing towards extra sensory insights into a hidden or secret world supposed to lie beneath the surface of our material life. However, we can say that the Shinto practitioners never got into the awkward and complex dogma of hierarchical worship. Rather, they merely approached each of their animistic inhabitations of spirit that they encountered with the proper fear and respect that one should properly apply to creatures or Gods we fail to yet understand.’ ‘It’s an interesting religion.’ I said, still utterly confused as to what the eccentric prince was attempting to convey.
‘I see you’ve mistaken my warning.’ De Montage continued in a more stern and serious tone, as we passed rows of trimmed hedges and decorative fences. ‘It is right to fear that which we don’t understand Master Hearst. We ought to treat our material supervisors with more respect. Now, I confess, it has never been the object of my ancestors to worship the unseen. Only a fool wishes to make a slave of themselves to a devil they don’t know. But respect, awe, fear, that is different. That is the core of wisdom. Now.... I confess to you... My own aristocratic ancestors, have had more of a vested interest in acquiring artefacts and precious minerals that can absorb such unknown energies. To tap into the mechanisms of nature and the outer spheres of unseen chemistry, that is where one can find the tools to bring about the acquisition of power!’ I began to become totally speechless, realising now, that I was in the presence of a lunatic. We were still about five minutes from the Serbian’s property, and De Montague now began to rave in such a strange and sinister manner, that he appeared some demented imp, his lecture was so insane. ‘So it was for the ones who claimed the future. Those beings with silken robes of silver, who sought the forbidden wisdom from beyond the abysses of Space and time. They are like the watcher, and we are but the conduits to their ancient digital powers. Yet if you could perceive the outlines of the Shapeshifter, who is the lost among us all, and he who brings the bitterness from the original tragedy. Then, perhaps you could understand what the Hindu’s really worship, in the form of their metamorphosising God of many evolutionary attributes.’ Mr De Montague suddenly stopped, slamming the steel cap of his staff upon the cracked concrete, and turned to me; ‘Mr Hearst, this is my warning for you! You cannot outwit the darker destinies of the force that itself conjures black holes. Have due reverence for the unseen beast which lurks beneath, and threatens your soul with eternal mutilation. Stand down from that property, and abandon your research into the disappearance of that accursed Serbian. I send this warning as a friend, and wether or not you take it up, I tell you that your colleague Greg will still make the sale, whichever path you choose.’ De Montague suddenly scowled like a rabid dog, grabbing my hand and thrusting the handle of his cane upon my palm. ‘Cursed child— I have the power of the Chiromancer, and that which is engraved upon your line of fate, makes it clear. But there is still time to evade the mark of this warning.’ Suddenly, I shrieked, for my palm began stinging with pain, and I realised that the silver etched handle of the staff was unfathomable degrees hot. I pulled my hand away before the impression became irreversible; ‘Ouch, you burnt my hand!’ I cried.
De Montague then seemed satisfied that his message had been delivered. He immediately hoisted back his staff, then let out a sound almost like a wolf’s growl. Then he seemed to perform a magicians trick of some form. For he cast the staff down at my feet, but as it fell there, a glimmer of light played a trick on me. I stepped back in fear, for that which lay across my feet, was no longer that of carven wood, but a coiled brown snake, who raised itself and hissed through fangs, and quivering forked tongue. I turned and dashed out of the snakes attack perimeter.
I gazed down at my stinging palm, to see with terror and trepidation that the burn mark in my hand imprinted from the image on the cane— it was the same strange glyph that was painted on the house.
Panting and sweating, tripping over my clumsy feet, as I rotated again to survey the scene, I saw now with incredulity the brown snake remained upon the pavement, but De Montague himself was long gone.
The hoax plagued me for hours afterward, I had been pranked it seemed, by some rich and bored eccentric trickster, who never intended to view the property at all. Or he was an escaped lunatic from Bourkeley Asylum perhaps. As I was already in the area, after a sufficient down time, when my heartbeat had reduced and my manic paranoia dissipated —I resolved to continue to Ormond Street anyway.
When I got to the property my fading anger was rebuked, for I saw two cars parked outside the late Serbian’s mansion. ‘Leisdadt’ I cursed.
As I walked up the modern staircase, I saw a cheerful looking man m, wearing a scarf, leaving, who Greg had obviously just shown around the property. He seemed fearfully optimistic about the place, and I continued cursing under my breath until I reached the hallway where Greg was standing, smugly, with a clipboard. He seemed even more satisfied when I came to the door; ‘You better watch out for that one’ Greg said in a tone that sent me into a rage; ‘He seems very keen. What happened to your 4’oclock?’ ‘Someone pulled a prank on me’ I cursed. I began to wonder if Greg had organised the incident with the charlatan somehow. Leisdadt tried hard to refrain from breaking out into a grin, ‘That’s a shame. Your luck has to come up one day Hearst.’ Leisdadt chuckled, but then seemed to remember something— ‘I thought you signed off on the clearance papers anyway Hearst.’ He said, ‘After Stacey White complained about the dead guy’s stuff still laying around, I thought you had the house completely emptied.’ ‘What of it?’ I asked. Greg leaned over to the ornately decorated mantle piece, pulling open the dresser drawer below the mirror and revealing a stack of haphazard papers and letters. ‘Can you take care of these?’ He insisted coldly, ‘I’ve got a last minute potential sale of that impossible property, 13 MacArthur Street. Can you believe my luck? We haven’t had a buyer for that place in years.’ I scowled into my neck as Leisdadt left via the rear entrance of the mansion. Grumbling and moving towards the papers, I cursed myself for so easily being persuaded to do what Greg could’ve done himself.
I mumbled, calling myself a sucker under my breath as I leafed through the papers.
Then, I turned over something which captured my interest. It was a sleek black diary, and as I turned the pages I came to realise that it had evidently belonged to Dimitrije. I flicked through the musty pages, seeing that the entries of the private journal dated up until the Serbian’s disappearance. I began to read with fascination and morose intrigue;
Here is the transcript of the more interesting parts of Dimitrije's diary: http://textuploader.com/dh4w4
Dimitrije Stojanovic died on the 13th of October, 2016.
The strange diary had a terrible effect on me. I became deeply paranoid that I was wedged within a catastrophic and deep conspiracy. Though I couldn’t fully understand the map laid out by the corners of my discoveries, there was enough of a pattern that I knew there was some terrible logic beneath it all.
I found the references to Vernon Towers and the architect ‘Von Marrickville’ extremely intriguing and began to further my own research on the property which was already familiar to me. I had always known that Vernon Towers was an old heritage building. But I had never researched the buildings actual construction. So it was, that I found out more about the strange creator, borrowing a book about the eccentric architect Veda Von Marrickville from Hexton library.
The book was fascinating. Von Marrickville, it turned out was a fairly prolific architect of the day, who was commissioned to build a series of buildings around Hexton city. Of particular interest to me, where the four or five buildings Von Marrickville built in a kind of arc around Port Phillip Bay, pointing towards Valsbury docks. Von Marrickville was a Dutch native who came out to Australia in 1834, one of the key buildings on the Port Phillip Bay side of Hexton was Vernon Towers, which I read to my astonishment was funded by a wealthy nobleman named Aaron De Montague. I couldn’t find out much about the De Montague family or their history in Australia, but I was beginning to think it must have been the same family as the De Montague whom I had met. Von Marrickville describe Vernon Towers as an ‘occult conduit’ and layered it with engraved symbology. He suffered a tragic fate, and wound up raving as an inmate in Bourkeley Asylum.
Since reading the diary, I have begun to experience strange anomaly. I visited Vernon towers myself, looking for a particular architectural feature. To my surprise and terror I saw one of the green glyphs mentioned by Dimitrije.
I tried to track down De Montage, however have not seen him since that odd encounter. Searching for families of that name, the only people I could come across in Hexton was a family living in Brunswick. When I went to visit I found them to be a strange family of Indonesians who incidentally suffered from an unusual diverse range of diseases. The youngest daughter suffered autism, whilst her brother was an extreme Down syndrome case, and the mother herself had mental health issues. I concluded that these De Montagues probably bore no relation to the man I had met, if indeed he hadn’t lied about his name.
Then there was the day I found that bizarre egg. It was about the size of a milk carton, all speckled and grey, but it was broken in half, as though it had hatched. Yet I was positive no animal could have produced the egg, and could only assume that it was a student art project or installation of some kind. In any case, it seemed unrelated to the other strange occurrences.
I feel as though my sanity has completely abandoned me, torn more and more towards the point of collapse. Leisdadt has sold the Serbian’s property, and I haven’t been to work for a week, for fear of the consequences with my boss.
But worse, I’ve started to smell a.... to sense something. Something that I recognise from Dimitrije’s descriptions in his diary. How is it possible to sense the form of something that you have never seen. To know it sometime. To dream of a shrieking thing that soars through a red sky.
That mosquito like head. Immense lizard like body, bone and ribs, like a sharks egg. Black leather wings.
There was a brown parcel that arrived in the mail. The statue inside matches the description given by Dimitrije. It’s so hideously disfigured. Does it represent the swimming demon in my dreams?
I examined the edges closely, and the inscription which seems to be flecked with blood. Could it be the murder weapon they used to bludgeon the Serbian? What of his shredded corpse, what tore his body apart? As I sit, hailed up in my lounge room trying to distract my mind with escapist television, and recording this journal on my IPad. I fear something unfathomable which seeks my destruction.
I can hear noises, am I hallucinating?
Dear God! That banging outside the house.
