Zsolt Felföldi

Zsolt Felfoldi is a core developer on the Ethereum Foundation's Geth team, within the protocol group that builds go-ethereum. He has worked on Ethereum's light client protocol, LES, and has been active in the ecosystem since at least Devcon1 in December 2015, where he spoke on progress toward an Ethereum light client. His public GitHub work includes a repository named Trustless Log Index and documentation for an LES server incentivization model, both directly related to his ETHBoulder 2026 talk on trustless log indexing and scalable Ethereum storage. That talk, tagged in the archive under EVM, indexing and analytics, and protocol, extends a body of work on Ethereum light clients and verifiable data serving that traces back over a decade in the ecosystem.
