Summary
🤩
Rockstar🎓
Top SchoolPéter Garamvölgyi is a Lead in Protocol Engineering with 11 years of experience focused on blockchain/DLT, programming languages, and machine learning, currently leading protocol work at Scroll. He has deep hands-on experience implementing and optimizing core blockchain sync and light-node features in Rust for Conflux and contributing protocol-level changes to Scroll’s Go-Ethereum fork, including opcode and hash-function modifications. His background spans R&D, infrastructure, and production engineering roles across Conflux and Scroll, plus early enterprise blockchain design in OCaml, giving him a rare cross-language systems perspective. Péter pairs academic training from Tsinghua and BME with practical open-source impact—his epoch-by-epoch and strided sync designs demonstrate attention to efficiency at protocol scale. He also brings community leadership experience from running Tsinghua’s blockchain association, reflecting strengths in outreach and technical mentorship. Notably, he blends low-level protocol tweaks with usability work like enabling logs and receipts for light nodes, showing both security-minded and developer-focused instincts.

scroll-tech/go-ethereum
Aug 2022 - Jan 2023
Scroll's fork of the official Go implementation of the Ethereum protocol
Role in this project:
Back-end Developer
Back-end DeveloperContributions:15 releases, 797 reviews, 22 commits in 5 months
Contributions summary:Péter primarily contributed to the core Go-Ethereum implementation, focusing on Scroll-specific modifications. Their work involved disabling the `SELFDESTRUCT` opcode, re-enabling the P2P layer, and changing the bytecode hash function from Keccak to Poseidon, which included code modifications and related testing. Additionally, they added the Scroll fee vault address as a fee recipient. These changes suggest a focus on protocol enhancements and security adjustments within the Ethereum fork.

Back-end Developer & Blockchain EngineerContributions:274 reviews, 432 commits, 356 PRs in 2 years 11 months
Contributions summary:Péter implemented and optimized core blockchain synchronization features within the Conflux-Rust repository. This included designing and implementing an epoch-by-epoch syncing mechanism, a new sync message type, and corresponding message handlers. The user also introduced an optimized, strided epoch-sync approach to enhance efficiency and reduce the number of requests. Furthermore, the user contributed to the light node functionality by enabling the return of log information, including the state root and logs, and managing the retrieval of transaction and receipt data from the blockchain.
