Ethereum Foundation has requested that Least Authority perform a security audit of the Zkopru (zk-optimistic-rollup) zk-SNARK Circuits and Smart Contracts. Zkopru, a Zcash-Style privacy solution, is a layer-2 scaling solution for private transactions using zk-SNARK and optimistic rollup on the Ethereum Blockchain. It supports private transfer and private atomic swap
Loopring is a flexible layer-2 scalability solution for basic value transactions as well as a variety of exchanges such as order book and Automated Market Maker (AMM). This system uses advanced cryptography in the form of a limited one-way homomorphic encryption using bilinear pairings, popularized in the implementation of the
O(1) Labs has requested that Least Authority perform a security audit of the Mina Ledger Application and its integration for the Nano S/X Hardware Wallet. Mina is a cryptocurrency with a lightweight, constant-sized blockchain utilizing zk-SNARKs and aims to improve scaling while maintaining decentralization and security. Our final audit report
Zero knowledge proofs (ZKPs) are an extremely robust, privacy-enhancing tool that can prove a computational statement is true without revealing the data behind it. While still at the early adoption stage, ZKPs are gaining traction as a potential solution to a vast array of privacy conundrums. These cryptographic building blocks
At the request of Zcash Company, the team at Least Authority had the opportunity to provide security consulting services on Zcash’s major 2018 releases. This included auditing Zcashd v1.0.15 (as part of the Sprout 1.0.x series), reviewing and providing feedback on the Overwinter and Sapling Specifications for future implementation, and a security review of the
