PROFILE
Elizaveta Pertseva
Elena Pertseva contributed to the GaloisInc/zk-lean repository by engineering features and fixes that advanced zero-knowledge proof automation, modular arithmetic, and bit-vector reasoning. She enhanced Lean-based proof tactics, introducing new modules for BVModEq and finite field operations, and refactored code for maintainability and modularity. Her work included developing tactics for range analysis, lemma application, and sign extension, as well as adding native support for 32- and 64-bit bitwise operations. Using Lean and Python, Elena addressed bugs in range analysis and proof validation, resulting in more robust, maintainable workflows and improved reliability for zero-knowledge protocol development.

Aug 1, 2025August 2025: Delivered two significant features in GaloisInc/zk-lean that strengthen modularity, reliability, and expressiveness for zero-knowledge proofs. ZkLean Modularity and Sign-Extend Lemma refactors imports for cleaner composition and introduces the sign_extend_mle_one_chunk lemma to ensure reliable sign extension in bit-vector arithmetic, backed by a build-fix commit. ZkLean 64/32-bit Bit-Vector Logical Operations adds native 64-bit and 32-bit AND/XOR operations to broaden the scope of verifiable bitwise computations in zk protocols. Overall impact includes improved maintainability, stronger proof capabilities, and a clearer path for future optimizations in zk-lean.
