Thomas Coratger
Cryptographic Engineer at Ethereum Foundation
Toulouse, Occitania, France
Summary
🤩
Rockstar🎓
Top SchoolThomas Coratger is a cryptographic engineer at the Ethereum Foundation who combines a PhD in applied mathematics with hands-on Rust development for core blockchain infrastructure. He has contributed to high-profile open-source projects like Reth—adding nuanced eth_call and trace block-override semantics—and refactored internals of rust-libp2p to strengthen protocol encapsulation and peer-to-peer behavior. Prior roles include core development on a zkEVM, leading blockchain research, and teaching, showing his ability to move from formal research to production-grade networking and consensus code. Based in Toulouse, he pairs numerical/mechanical engineering roots with rigorous math to deliver precise, pragmatic solutions at the intersection of cryptography, distributed systems, and P2P networking.

Modular, contributor-friendly and blazing-fast implementation of the Ethereum protocol, in Rust
Role in this project:
Back-end Developer
Back-end DeveloperContributions:344 reviews, 459 PRs, 553 comments in 1 year 11 months
Contributions summary:Thomas contributed to the development of the Reth Ethereum protocol implementation, specifically focusing on the eth rpc component. Their work involved adding functionality related to "block overrides" in the `eth_call` and `trace_*` methods, which enhances the RPC's ability to simulate execution environments. This included changes across multiple modules, implementing features in the RPC and engine APIs, and adjusting revm utilities. The user also converted `vec` to `Bytes` in `Nibbles` data structure.

The Rust Implementation of the libp2p networking stack.
Role in this project:Back-end Developer
Back-end DeveloperContributions:103 reviews, 26 PRs, 135 comments in 3 months
Contributions summary:Thomas primarily focused on refactoring and improving the `libp2p/rust-libp2p` networking stack by making various modules private to encapsulate internal implementation details. Their work included deprecating the `mplex` module in favor of `yamux`, enhancing the Kademlia and gossipsub protocols, and removing deprecated items throughout the codebase. They also contributed to the file-sharing example by integrating the `cbor` codec for request-response operations.
