BLAKE3 implementation extracted from the reference implementation and compiled to WebAssembly.
import {blake3} from 'https://bitvm.github.io/blake3/blake3.js'
const preimage = new Uint8Array([97, 98, 99]) // Our preimage is "abc"
const digest = blake3(preimage)
console.log(digest)The following command compiles the sources to wasm:
clang src/blake3.cpp -O2 --no-standard-libraries -mbulk-memory --target=wasm32 -Wl,--no-entry -o blake3.wasm
