Valery Cherepanov
Valery contributed to the axiom-crypto/openvm-reth-benchmark repository by engineering a performance-optimized Merkle Patricia Trie (MPT) for zkVM, refactoring the node structure to use arena-based memory management and implementing RLP encoding with zero-copy deserialization in Rust. To address MPT integrity, Valery developed a recursive subtree-duplication function that ensures child nodes are correctly copied during extension-node creation, preventing invalid references. In addition, Valery improved CI efficiency by introducing a build cache for cargo-openvm using GitHub Actions and YAML, reducing redundant installations and accelerating benchmark cycles. The work demonstrated depth in data structures, performance profiling, and CI/CD optimization.

1 Commits • 1 Features
Sep 1, 2025September 2025 focused on improving CI efficiency and build reliability for axiom-crypto/openvm-reth-benchmark. Delivered a dedicated CI Build Cache for cargo-openvm, adding restore and save steps to cache the cargo-openvm binary. This eliminates redundant installations and speeds up CI builds when the binary is cached, accelerating benchmark iterations and nightly validation.

Aug 1, 2025Month: 2025-08 performance summary for axiom-crypto/openvm-reth-benchmark. Implemented targeted Merkle Patricia Trie (MPT) optimizations for zkVM, including an arena-based node structure, RLP-encoded MPT with zero-copy deserialization, and integrated benchmarking/profiling. Addressed a critical MPT integrity issue by adding a recursive subtree-duplication function to copy child nodes into the new arena during extension-node creation, preventing invalid references. Commit references: ca6efb5ba62187612f8e220e4e1e0b44ba9b7700 (perf: RLP-based MPT with zero-copy deser) and 516ed3666111dc7fb89d18052217860c0930065e (fix: dangling nodes in build_mpt). Business impact: higher zkVM state throughput due to faster MPT operations and more reliable builds, laying groundwork for scalable state management. Technologies/skills demonstrated: Rust/system programming, arena-based memory management, MPT optimization, RLP encoding, zero-copy deserialization, benchmarking and profiling, code refactoring for performance.”
