PROFILE
Thomaslavaur
Thomas Lavaur contributed to the logos-co/nomos-pocs repository by engineering and refining zero-knowledge proof circuits for blockchain applications over six months. He developed and overhauled core circuits such as Proof of Leadership, Proof of Quota, and Proof of Claim, focusing on correctness, security, and maintainability. Using Circom, Python, and Rust, Thomas standardized input handling, upgraded cryptographic primitives from SHA-256 to BLAKE2b, and implemented robust validation logic to prevent invalid proofs. His work included circuit refactoring, input tooling, and legacy cleanup, resulting in a more reliable, scalable codebase that supports advanced cryptographic protocols and production-ready smart contract workflows.

Jul 1, 2025Month: 2025-07 | Focused on correctness and reliability improvements for leadership proofs in the logos-co/nomos-pocs repo. Implemented a critical fix to Leadership Proof Validation to ensure proofs only proceed when a note is both winning and unspent. This was achieved by restructuring the Circom circuit, renaming the template to would_win_leadership, and integrating an unspent membership check with the winning conditions. The change reduces risk of invalid leadership proofs being accepted and strengthens end-to-end proof integrity. Key commit: 876d7d6d8eb63ad7f680469550e6b443eeb2e953 (message: change win pol by would win).

May 1, 2025Concise monthly summary for 2025-05 focused on nomos-pocs engineering work. Key features delivered include the Proof of Quota (PoQ) circuit and tooling with an input generator, enabling Blend protocol support; Proof of Leadership (PoL) circuit improvements with versioned templates and updated input generation (including KDF versioning); and a codebase refactor to standardize naming (ownership -> zksignature) with cleanup of deprecated elements. Additionally, cryptographic constants were updated and hashing switched from SHA-256 to BLAKE2b to improve security and performance.
