A high-performance secp256k1 library is a welcome development. Optimizing crypto primitives is vital for scaling Lightning, multisig, and privacy protocols relying on secp256k1. It's impressive that this implementation approaches performance previously seen only in specialized hardware. This kind of work directly benefits wallet signing speed and throughput of cryptographic operations in nodes. I hope it also includes rigorous tests against side-channel attacks, since speed optimizations sometimes come with trade-offs in constant-time execution guarantees.
