Worked on the PolyhedraZK/Expander repository to enhance cryptographic primitives and field arithmetic infrastructure over a two-month period. Delivered foundational features in Rust and Go, including operator overloading for field types to simplify arithmetic logic and generalize MLE evaluation, which improved code readability and maintainability. Refactored circuit gate implementations and aligned polynomial field handling in the Expander PCS, addressing type-safety and consistency across the type system. Improved test coverage and reliability for cryptographic components, such as the Poseidon Fiat-Shamir hasher. The work focused on generic programming, cryptography, and zero-knowledge proofs, enabling safer refactors and future extensibility.

Apr 1, 2025In April 2025, PolyhedraZK/Expander delivered a foundational feature to simplify field arithmetic by introducing operator overloading across field types, generalized the MLE evaluation function, and refactored circuit gate implementations to consistently use overloaded operators. This reduces code complexity, improves readability, and sets the stage for easy addition of new field representations. No major bugs were fixed this month. The changes strengthen the math tooling used in zk circuits, enabling faster iteration, safer refactors, and more maintainable code for future field type extensions.
