Which is trivially bypassed by an actual implementation of the proof of work in non-javascript, rendering it absolutely useless. The website is approximately 3800x times slower than native code, and hundreds of thousands of times slower than the CUDA kernel claude wrote. The "proof of work" is just non existent at that point, they're solved in milliseconds for what would take the browser version 10 minutes or more, it's security by obscurity being dressed up as something more.

Claude even made a nice little API server for it after implementing midstate compression, AVX multi way hashing, and a CUDA kernel. This doesn't stop the literal LLM it's trying to block from solving the challenges, it's really annoying that everybody is using it and claiming that it's something that's usable in the real world as a result of it using proof of work. It's obscure, and obscure is fine so long as nobody is pretending that it is secure.
