Greetings!

Monero vanity address generation can currently only be done via CPU.

This is annoying.

Therefore I am delighted to announce that the Modular Font Editor K Foundation, Incorporated, a New Jersey non-profit (which, despite its name, is a charity that I use to fund free software in general), is offering a bounty of $3,099 to be paid however the accepting user prefers for a Monero (XMR) vanity address program meeting these specs:

  • works on GNU/Linux
  • works with NVIDIA cards (my laptop has NVIDIA GeForce RTX 3080 Laptop GPU, so that's the minimum featureset)
  • is command line driven
  • uses either CUDA or OpenCL as stated in subject line
  • accepts at least a single search prefix on the command line for the public receive key
  • is at least 4x faster than https://github.com/monero-ecosystem/vanity-monero, which should be no problem as you are writing a GPU-driven app
  • reports the number of keys it's considering every n seconds
You agree that the program you produce will not receive the bounty unless it is licensed under the Apache 2.0 license. You agree that you will include above the copyright line of the Apache 2.0 license, which the license requires redistribution of, this text:

Code:
Support for this software's development was paid for by Fredrick R. Brennan's Modular Font Editor K Foundation, Inc.

Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

Here you go: https://github.com/SChernykh/vanity_xmr_cuda

You can send the bounty to my XMR address:

I am just seeing this now. I will verify your program works as intended, but it seems to be in order from README.

Thank you, I am incredibly impressed.

I did the following tests to make sure that this was a legitimate solve:

1. I ran the existing Golang implementation:
Code:
fred@mapache:~/Workspace/vanity-monero$ go run cmd/vanity-monero/main.go
Select work mode:
1) Standard mode
2) Split-key mode
3) About
Your choice: 1

Select network:
1) Monero main network
2) Monero test network
3) GRAFT main network
Your choice: 1

Select mnemonic seeds language:
1) English
2) Dutch
3) Esperanto
4) Spanish
5) French
6) German
7) Italian
8) Japanese
9) Lojban
10) Portuguese
11) Russian
12) Chinese (Simplified)
Your choice: 1

Select match mode:
1) Prefix from the 3rd character. (fast)
   For example, pattern "Ai" matches "42Aiabc..." and "48Aiabc...".
2) Prefix from the 1st character. (medium)
   For example, pattern "44Ai" matches "44Aiabc..." and "44Aidef...".
3) Regex. (slow)
   For example, pattern ".*A[0-9]{1,3}i.+" matches "44abcA233idef...".
   Note that in Regex mode there is no guarantee that there exists such address matching the pattern.
Your choice: 1

Enter your prefix/regex, which must be in ASCII and not include 'I', 'O', 'l': speak
Case sensitive? [Y/n] n
Specify how many threads to run. 0 means all CPUs: 0

Fantastic.

I then loaded a generated address into MyMonero to make sure we have a match—

Code:
651507438fb1691ec1c617ea1773ad93b0036fd79295ee8173c98f4c6de72e0c 46SPEAKZWk9PtTM2Ziitmh5msxYDowPbNPKxid2wwUVBgghMzxPJMTBTZr8S6ngick7tmNUapWRsSd8ouAJdsPKU17gHfr9

I found this helpful page—https://xmr.llcoins.net/addresstests.html which gave me after clickig a bunch

Code:
46SPEAKZWk9PtTM2Ziitmh5msxYDowPbNPKxid2wwUVBgiMXXf8T7vVGq9Vco38GSBCYGoJ1vD81a9Vnr5MHUHUx95QQX7z

Note the mismatch beginning after 46SPEAKZWk9PtTM2Ziitmh5msxYDowPbNPKxid2wwUVBg, where next token becomes i….

Clearly this still works, but I'm weary of why this is happening and hope for an explanation. You've clearly done the bounty so deserve the money, so no one else should work on this while you're preparing answer.

It's most likely a display bug. The second half of Monero address is a public view key, so the bug must be somewhere there. I'll look into it.

Edit: it seems that https://xmr.llcoins.net/addresstests.html gives a wrong address. monero-wallet-cli generated 46SPEAKZWk9PtTM2Ziitmh5msxYDowPbNPKxid2wwUVBgghMzxPJMTBTZr8S6ngick7tmNUapWRsSd8 ouAJdsPKU17gHfr9 for this spend key which is what my generator printed out.

Writing here to confirm that I received the bounty Smiley

Thank you sech1, I have been able to verify this on my side as well on behalf of the Modular Font Editor K Foundation, Inc.

12 XMR was paid in transaction 2d84f1d38a6d149ce66f1f13507a55600e67436b16ca821f5f7c607a89ac93f9 from 44tHANKU69BUSJwcseRfNDecr1D8Z61X6gfpKmU1BfQMgUUqqkUufMY8EGdFXz6uTJ4w9Ggc8rmEheuSvYfXDKq85F5i gyx with payment ID 4563636c2e313a32 (ASCII: Eccl.1:2).

This bounty is closed and no more payments will be made to other parties. Thank you very much!

I apologize for problems we (mostly I) had due to buggy wallet MyMonero. Won't be using anymore. It shows a completely wrong address (not yours) but I was able to load your viewkey in Feather and generate this inproof:
