The Credibility Is in the Work All audits are significant in their own ways, but some stand out for their technical complexity, ecosystem influence, or global significance. As we approach the milestone of having completed 300 security audits, we wanted to take a moment to reflect on what this achievement
We performed a security audit of the zkBTC Circuit Implementation and Smart Contracts. zkBTC Bridge is a native zero‐knowledge proof-based cross‐chain protocol by Lightec that enables Bitcoin holders to convert BTC into an ERC-20 token, $zkBTC, on Ethereum at a 1:1 peg. Our final audit report was completed on June

Least Authority has been awarded a grant from the Ethereum Foundation’s Verified zkEVM program to create a comprehensive Lean blueprint for two cryptographic protocols, STIR [ACF+25] and WHIR [ACF+24], which are interactive oracle proofs of proximity (IOPPs) for Reed-Solomon codes. The zkEVM Program is a recent initiative that aims to
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
