ASICs & Scope of their Advantage


#1

Hello!

I have a doubt that perhaps someone more knowledgeable here could help me solve it (or test it!). As far as I understand, ASICs equipment is highly specific to their function and therefore leaves little to no flexibility.

Bitcoin’s ASICs, for instance, is designed to:

  • perform a double sha256 hash
  • hashing 80 bytes
  • find the 4 zero-bytes

My doubt is as follow: what would be the expected relative advantage of an ASIC (like S9) vs a GPU if we were to perform a triple sha256 hash, sha256(sha256(sha256(x)))?

Thanks!

ps: This is for a small side project, I’m not proposing using triple sha256 to “fight ASICs”
