PROFILE
Andrew Milson
Worked on feature development in Rust across cryptography and zero-knowledge proof systems, contributing to starkware-libs/stwo-cairo and a16z/jolt. Delivered Cairo serialization support for Blake2sHash, enabling hash values to be converted into FieldElements by chunking bytes into u32 words, which streamlined interoperability for Cairo contracts. In a16z/jolt, implemented on-the-fly LT polynomial evaluation by introducing the LtPolynomial struct and refactoring ValEvaluationSumcheck, reducing memory usage by avoiding pre-computation and storage of the entire polynomial. Focused on memory optimization, serialization, and polynomial commitments, the work addressed scalability and integration challenges in cryptographic contract and proof system development.

Oct 1, 2025Month: 2025-10 — Key accomplishments in a16z/jolt: implemented on-the-fly LT polynomial evaluation to reduce memory usage in ValEvaluationSumcheck by introducing LtPolynomial and refactoring the computation path. This avoids pre-computation/storage of the entire LT polynomial, yielding a smaller memory footprint and improved scalability for larger proofs. The change is backed by commit 30c5053c42fb550f0124999a694dd721ff44f636 with message 'Reduce memory in ram/val_evaluation.rs by computing LT on-the-fly'.

Apr 1, 2025April 2025 monthly summary for starkware-libs/stwo-cairo focusing on feature delivery, bug fixes, and overall impact. Key feature delivered: - Cairo serialization support for Blake2sHash: Enabled serialization of Blake2sHash values into FieldElements by chunking hash bytes into u32 values and serializing each chunk. This enables Blake2sHash to be used in Cairo contracts directly (commit bde0d3a552c7280e27b3a249d85ee37ac55f642e).
