Spartan-ecdsa (which to our knowledge) is the fastest open-source method to verify ECDSA (secp256k1) signatures in zero-knowledge. It can prove ECDSA group membership 10 times faster than efficient-zk-ecdsa, our previous implementation of fast ECDSA signature proving. Please refer to this blog post for further information.
