Sorry if this seems like a dumb question. But wouldn't it be more effective and much more performant to use an ASIC miner for the computational tasks of VanitySearch instead of a modern GPU? My GPU does 1,750 MKeys/sec and in comparison to that a GekkoScience Compac F USBminer does about 300 GHashes per second. Is there possibly a VanitySearch version that uses such a Compac F for the calculation and thus works much faster, any clues ?
It's impossible to use ASIC miner (such as SHA-256, Scrypt or X11) since there are many cryptography involved to create Bitcoin address such as ECDSA with secp256k1 curve, RIPEMD-160 and SHA-256. There's also various other operation such as checksum function on Bech32 and Bech32m address.
It's different scenario if you're talking about creating ASIC to generate vanity address.
