The zero-knowledge space is rapidly gaining traction as privacy becomes a critical concern due to the daily news of data breaches that expose personal information to malicious actors. With the exponential growth of data collection and the increasing reliance on cloud services and decentralized technologies, individuals and organizations are seeking
Since 2015, Least Authority has been working with zero-knowledge proofs (ZKPs) to further enable privacy, improve security, and encourage the implementation of zero-knowledge proofs in Web3 technologies and beyond. Although Zcash spun out of Least Authority with the Electric Coin Company in 2016, we continued to work on zero-knowledge proofs
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
Tools for Humanity requested that Least Authority perform a security audit of its ZK Prover, a modular zero-knowledge proof toolkit optimized for mobile devices. Our final audit report was completed on May 11, 2026. To read the full report, including our findings, click here: Report
Privacy depends on more than promises or compliance. This blog explains how policy creates obligations, but system architecture determines outcomes, shaping what data can be collected, linked, or exposed. Why Law Creates Obligations—but Architecture Determines Outcomes Privacy failures are rarely the result of a single mistake. More often, they emerge
Data protection laws often do not apply to the lesser-known category of “anonymous data”. There are misleading claims and new risks. Privacy’s Newest Threat It’s no secret that in today’s digital economy, an era in which data is the new oil, entities are collecting, sharing, and analyzing personal information at
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 But that assumption is outdated.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
Aligned Layer is a verification layer for zero-knowledge proofs using Eigen Layer. Our team recently performed a security audit of the Aligned Layer system as part of a multi-firm audit, targeting Aligned Layer version 0.4.0. In this review, we performed a follow-up audit, focusing on the changes between Aligned Layer
