A commnand-line vanity address generator for Grin. I made this mostly for fun and to familiarize myself with the various Grin libraries written in Rust. The code is currently a lot slower than expected since deriving a slatepack address from a seed seems to be ~1000x slower that deriving it from a raw public key.
cargo install grin-vanityThe output below depicts an adrress found with the pattern grin1test and its corresponding seed.
$ grin-vanity --threads 30 --pattern grin1test --interval 180

Guessing a private key with the chosen prefix has an element of luck to it. The following table depicts a rough estimate on what should be expected on a Ryzen 5950x using 30 threads. Your results may vary.
| Prefix | Eta |
|---|---|
| grin1 | < 1s |
| grin10 | < 1s |
| grin100 | < 1s |
| grin1000 | 30 s |
| grin10000 | 16 min |
| grin100000 | 9 h |
| grin1000000 | 12 d |
| grin10000000 | 17 y |
| grin100000000 | 560 y |
