Our team performed a review of the recent changes to World‘s secure multi-party computation protocol V2 (SMPC Protocol), which is used to match a given iris against a database of iris shares. In this third review, we audited the changes implemented in the second version of the protocol since our
Warlock has requested that Least Authority perform a security audit of Sylow and SolBLS. Sylow is a Rust library for elliptic curve cryptography, specifically tailored for the BN254 curve, and SolBLS is a Solidity library optimized for on-chain BLS signature verification. Our final audit report was completed on January 6,
Our team performed a security audit of World‘s secure multi-party computation protocol (SMPC Protocol), which is used to match a given iris against a database of iris shares. Our team previously reviewed this implementation and delivered a Final Audit Report on April 4, 2024. In this review, we examined the
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
Least Authority performed a security audit of World’s SMPC Protocol for the uniqueness check of iris codes. To read the full report including our findings, click here: Report
Our team conducted a second review of the upgrades to World‘s semaphore-mtb and the signup sequencer. Previously, our team had conducted a review of an earlier version of the codebase, which included World’s Rust implementation of the semaphore protocol and the Go implementation of the Semaphore Merkle Tree Batcher (SMTB).

Least Authority has been requested to perform a security audit of Sygma. Sygma provides an interoperability layer between blockchains and is intended to facilitate cross-chain functionality for dApps. The system is composed of a network of validators that run the relayer implementation, and smart contracts on the source and destination
