Summary
🤩
RockstarPeter Miller is a Research Scientist and independent Ethereum researcher based in Edinburgh with 16 years of software engineering experience, currently funded by the Ethereum Foundation to work on next-generation Execution Layer specifications. He contributes to high-impact open-source projects such as the execution-specs and paradigmxyz/reth, where his backend work in Rust has improved protocol correctness, performance, and historical state handling. His contributions include making core types immutable, switching balance representations to U256, fixing gas-price handling for EIP-2930, and ensuring genesis accounts are correctly reflected in changesets—work that directly shapes network upgrade tooling. Comfortable at the intersection of formal specification and production-grade implementation, he brings a pragmatic focus on correctness and efficiency to protocol design.
