Have you already thought about whether it could be compiled to run in a browser? Would a hand-optimised js implementation be a terrible idea?

This is very interesting, thanks for sharing it!

dear Jeremy,

Have you already thought about whether it could be compiled to run in a browser? Would a hand-optimised js implementation be a terrible idea?

This is very interesting, thanks for sharing it!

Of course I'm very keen on getting it to run in browsers, and I've looked hard at javascript and other languages compilable to javascript. But the big stumbling block is lack of support for 64 bit ints. Cuckoo Cycle is very big on 64-bit ints, and expressing those as pairs of 32-bit ints is not only extremely painful in source code, but also a recipe for dismal performance. I've not been able to find a language with 64-bit ints that compiles to js, and would at least avoid the source code pain.

So I'm waiting for webasm to mature, since it looks like it will have full 64-bit support...

regards, -John

Looks like it's coming to Chrome https://github.com/tc39/proposal-bigint/issues/53#issuecomment-451677909

Why support cryptojackers? IMHO it's a good thing that Cuckoo doesn't work well in browsers.
