Lightec – zkBTC Bridge Cryptography

Lightec requested that Least Authority review several components of the zkBTC protocol, which is a bridge between Bitcoin and Ethereum, using techniques from zero-knowledge proofs. The bridge allows a Bitcoin user to mint a zkBTC token, use this token in the Ethereum ecosystem, and eventually redeem the Bitcoin from the

Polygon – Plonky3

Our team performed a comprehensive audit of Polygon’s Plonky3, a toolkit for an efficient implementation of a non-hiding STARK protocol. The codebase consists of different cryptographic building blocks (such as fields, hash functions, polynomial commitment schemes, and others) that can be combined into STARKs. The overall goal is to build
