Hello,

I was doing research on various Vanity search algorithms and stumbled upon this repo:

https://github.com/fpgaminer/fpgaminer-vanitygen

I did a state diagram to understand it better:

as the math behind it is well above my pay grade.

So my question is - what algorithm is that ? Is this a part of OpenSSL standard elliptic curve functions ? Or something custom ?

Unlike most Vanity search programs that usually generate random k, then produce x and hash it, this algorithm seems to be using
only public keys (x and y are needed for next iteration) and finds the next public key without dealing with private keys.

Thank you!
