Much Faster Signatures on secp256k1

I’ve just released a new version of ppad-secp256k1 that supports dramatically faster Schnorr and ECDSA signature schemes, powered by faster elliptic curve arithmetic under the hood. This follows on my previous posts in what are starting to constitute a sort of secp256k1 series. In the last post I had used the wNAF method for elliptic curve scalar multiplication to glean a large performance boost…
