It took a year to ship WebAssembly in Anubis

After a year of work, hundreds of commits, 5 generations of pull requests, dozens of tests, rewriting part of Anubis in Rust, the first compiler bug of my career, and at least three times making my tower run out of ram I think I have finally done it. The next version of Anubis will ship with WebAssembly-based proof of work checks that admins can enable in their thresholds or bot rules: thresholds: - name: moderate-suspicion expression: all: - weight >= 10 - weight < 20 action: CHALLENGE challenge: algorithm: argon2id difficulty: 6 This makes Anubis challenges use a memory-hard proof of work function (argon2id) instead of just a CPU hard one. It also means that the "hey Claude vibeslop me a CUDA Anubis solver" route is on its way to being fundamentally dead. Overall, this project taught me a lot of things about how WebAssembly works in practice, what the rough edges are when operating on the bleeding edge like I am, and led to the first genuine compiler bug of my career. Today I want…
