Common Prefix — Mysten Labs

Mysten Labs

Mysten Labs is the team behind the Sui blockchain and Move programming language. Sui is an L1 that utilizes a unique DAG-based consensus mechanism based on Narwhal and Bullshark. Common Prefix is actively collaborating with Mysten Labs, auditing core components of their protocols. So far, Common Prefix has audited various components of the fastcrypto library, including ECVRF, Ristretto255, BLS12381, ECDSA Secp256k1, and ECDSA Secp256r1. The Sui implementation relies on cryptographic primitives provided by the fastcrypto library for its consensus and execution layers. Through these audits, we evaluate security, ensure adherence to standards, and provide recommendations to optimize performance and code quality. Additionally, we audited core components of Mysten's Seal decentralized secrets management (DSM) service.

Seal Cryptography Specification and audit

Mysten Labs commissioned Common Prefix to audit the core components of the Seal decentralized secrets management service. Seal enables users to encrypt messages while specifying a set of conditions for their decryption.
