Valery Cherepanov
Valery contributed to the axiom-crypto/openvm-reth-benchmark repository by engineering performance-focused enhancements to the Merkle Patricia Trie (MPT) for zkVM state management. Their work included refactoring the MPT to use an arena-based node structure, implementing RLP encoding with zero-copy deserialization, and introducing benchmarking and profiling instrumentation. Valery also addressed critical bugs, such as fixing dangling node references and resolving branch-collapse issues during key deletion. They improved CI efficiency by adding build caching for Rust binaries and optimized memory usage through precise buffer sizing and caching strategies. This work demonstrated depth in Rust, data structures, memory management, and CI/CD automation.

1 Commits • 1 Features
Feb 1, 2026February 2026 — axiom-crypto/openvm-reth-benchmark: Focused on performance optimization of the Merkle Patricia Trie (MPT). Key feature delivered: MPT Performance Optimizations, including using Cell for cached references, precisely sized encoded path buffers, and bypassing nibble decoding on frequently accessed paths to improve node reference handling and memory usage. This work supports benchmark scalability and stable long-running tests. There were no explicit bug fixes recorded this month; the optimizations reduce inefficiencies and enhance stability in benchmark runs. Overall impact: higher potential benchmark throughput with lower memory footprint, enabling more scalable testing of RETH functionality. Technologies/skills demonstrated: low-level data structure tuning, caching strategies, buffer sizing optimization, and performance-focused code refinement.

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.”
