What if Privacy Were the Default? Most digital services still require accounts, personal data, and behavioral tracking permissions, even for simple actions. It’s often assumed that convenience depends on identity. But that assumption is outdated. Tools like anonymous credentials make it possible to build services where an identifying profile is
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
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
Our MoonMath Manual to zk-SNARKs is generating a lot of interest and so we’ve put together answers to some of the most common questions. What are zk-SNARKs and why should I care? Zk-SNARKs, or zero-knowledge succinct non-interactive arguments of knowledge, is a type of zero-knowledge proof that allows for the
Least Authority is pleased to announce the publication of the Zero Knowledge Access Passes (ZKAPs) Whitepaper. The paper is intended both for technical and non-technical audiences. ZKAPs, or Zero-Knowledge Access Passes, provide an anonymous, token-based authorization protocol based on Privacy Pass that facilitates an online exchange of value while disconnecting
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
A note from the team: we’re continually looking for possible applications of ZKAPs in a variety of scenarios. If there is a product or project you’re working on that you would like to test ZKAPs with, don’t hesitate to get in touch! Last month, our team, the Least Authoritarians, gave
