Supporting application R&D on Ethereum and decentralized platforms.
zk-ECDSA Part 2: Under the Hood by Yi Sun, Tony L., Wen-Ding L., and gubsheep Earlier this year, we presented circom-ecdsa, an efficient proof-of-concept implementation of zkSNARK circuits for ECDSA algorithms in circom. This post goes more in-depth on some of the building blocks that go into the circuit constructions. In a future post, we'll also discuss some of the more advanced optimizations we implemented for secp256k1 operations. How does ECDSA work? In Part 1 of our zk-ECDSA series, we covered the role that the Elliptic Curve Digital Signature Algorithm (ECDSA) plays in networks…
