kopipe proposes $3,099 bounty for Monero vanity address generator that uses OpenCL or CUDA

kopipe¹ has proposed a $3,099 bounty² for the creation of a Monero vanity address generator CLI app that uses either OpenCL or CUDA and is at least 4 times faster than the existing CPU-driven vanity-monero³ tool:

Monero vanity address generation can currently only be done via CPU. [..] the Modular Font Editor K Foundation, Incorporated, a New Jersey non-profit [..] 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 [..]

Specs

• works on GNU/Linux
• works with NVIDIA cards (minimum: NVIDIA GeForce RTX 3080 Laptop GPU)
• is command line driven
• uses either CUDA or OpenCL
• 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
• reports the number of keys it’s considering every n seconds

Note that the bounty will not be paid unless the software is licensed under the Apache 2.0 license and includes this copyright line:

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

The bounty was also posted on Monero Bounties⁴, but it is unclear if the donation bot is fully operational again⁵.

To learn more about generating custom/vanity XMR addresses, consult the vanity-monero repository README⁶.

Update: bounty paid to sech1⁷ for vanity_xmr_cuda⁸.
