PROFILE
Andrew Milson
Andrew Milson developed two core features across the starkware-libs/stwo-cairo and a16z/jolt repositories, focusing on serialization and memory optimization in Rust and Cairo. For stwo-cairo, he enabled Blake2sHash serialization into FieldElements by chunking hash bytes into u32 values, allowing direct use in Cairo contracts and improving contract interoperability. In a16z/jolt, he refactored the ValEvaluationSumcheck to compute Lagrange polynomials on-the-fly using a new LtPolynomial struct, reducing memory usage by eliminating the need to precompute and store the entire polynomial. His work demonstrated depth in cryptography, serialization, and zero-knowledge proof systems, addressing practical scalability challenges.

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).
