YoungWoo Yang
Rust engineer contributing to Ethereum core infrastructure — including consensus clients (Lighthouse) and developer tooling (Foundry, Alloy). Focused on protocol-level implementation and performance optimization across Ethereum’s execution and consensus layers.
Experience
Cosmos Core Infrastructure
Cosmos EVM
Removed a redundant LockedCoins store read in GetAccount by deriving spendable and locked balances from a single read in a shared helper, cutting allocations ~4.5% and serial block-execution time ~2.3%. (PR #1203, Open)
Ethereum Core Client
Lighthouse
Added peer penalties and explicit error handling for payload envelope gossip based on Gloas P2P spec. (PR #8981, Merged)
Alloy, Ethereum Tooling & Infrastructure
Foundry
Co-authored a feature to prevent keystore overwriting in cast wallet new by implementing the core interactive confirmation logic. (PR #13679, Merged)
Alloy
Fixed an infinite polling bug during network reorgs by implementing a block gap timeout mechanism. (PR #3551, Open)
