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
Threshold signing protocols, like FROST, help to facilitate trust while avoiding the reliance on a centralized authority. They do this by fault-tolerantly distributing information or computation among a cluster of cooperating computers. With the rapid advancement of secure digital systems, threshold cryptography is gaining traction through securing multi-signature wallets, protecting
In today’s rapidly evolving tech landscape, ensuring robust security is more than a checklist—it’s a collaborative journey. At Least Authority, our process begins by working closely with our client to define the audit scope and secure the essential documentation and resources. Through in-depth technical discussions, we pinpoint key concerns and
Can Artificial Intelligence Be Integrated Into Our Workflow? At Least Authority, we are always exploring innovative ways to enhance our security auditing processes and improve our ability to identify vulnerabilities. One area of particular interest is the usefulness of various Artificial Intelligence (AI) models and how they can be integrated
Background The newly adopted European Union (EU) Regulation on Markets in Crypto-Assets (MiCA Regulation) aims to provide a unified framework to regulate crypto-asset markets. Crypto-assets are defined in the MiCA Regulation very broadly as ”a digital representation of a value or of a right that is able to be transferred
