love it, pls consider using equihash as a PoW algo

[stef]

equihash is a PoW algo that

• is memory hard (you need configurable amounts of RAM to solve the challenge)
• unlike sha256 there is no gpu/hw assist that makes it cheap to calculate and circumvent (especially with bitcoin miners)
• is very cheap to verify (so no extra cost for the server)

tor uses a variant of equihash for ratelimiting, and i maintain a library that implements the original at https://github.com/stef/equihash

Do you have a build flow for that library that emits webassembly modules? Would make it a lot easier to integrate into Anubis.

[stef]

no, but i'm pretty sure emscripten can build this into wasm. i'm a systems programmer not a web-frontend person, for one of my other projects some kind soul donated a js/wasm binding, maybe this could be used as a starting point for getting equihash as wasm: https://github.com/stef/libopaque/blob/master/js/Makefile

Perfect, I'll take a look when I get home. I just did a talk at a local meetup and mentioned Anubis there!
