Jared Wasinger
Software Developer at Ethereum Foundation
United States
Summary
🤩
RockstarJared Wasinger is an experienced software developer with 11 years focused on core blockchain clients and protocol work, currently contributing to go-ethereum at the Ethereum Foundation. He combines deep protocol-level engineering with QA and CI expertise, having improved testing, automation, and debugging tools across major projects like go-ethereum, ethereumjs, Aleth, and the ethereum/tests suite. His contributions include implementing EVM opcode behavior (SELFDESTRUCT, CALL, CREATE2, EXTCODEHASH), state-pruning and EIP logic, plus new debugging methods for state analysis and production telemetry support on BSC. Jared’s background in SRE and build/test automation gives him a strong operational lens for making low-level changes robust and verifiable. Not actively seeking employment, he nonetheless continues to shape critical open-source infrastructure used by multiple Ethereum clients and chains.

Go implementation of the Ethereum protocol
Role in this project:Back-end Developer & Security Engineer
Back-end Developer & Security EngineerContributions:400 reviews, 13 commits, 182 PRs in 3 years 6 months
Contributions summary:Jared primarily contributed to the core Ethereum protocol implementation, specifically by introducing a new debugging method (`debug_accountRange`) for state analysis and by implementing functionalities related to the "self-destruct" operation. Their work involved modifying core API components and test suites, indicating deep involvement in the protocol's internals and its security implications. Further, the user enhanced the system's robustness by fixing edge cases in the LOG and SELFDESTRUCT opcodes and implemented critical features such as the EIP-6780.
