Summary
🤩
Rockstar🎓
Top SchoolThomas Coratger is a Post-Quantum Ethereum team leader and research engineer with a PhD in applied mathematics, blending deep numerical modelling background with hands-on blockchain engineering. He leads research and implementation of post-quantum cryptography for Ethereum while contributing to high-impact Rust projects like rust-libp2p and Reth, where he improved networking primitives and enhanced eth RPC simulation capabilities. With experience across zkEVM, cross-chain oracle systems, and academic teaching, he bridges rigorous research and production-grade protocol engineering. Notably, his work on encapsulating libp2p internals and adding block-override semantics to eth_call reflects a focus on robust, composable infrastructure for decentralized systems. Based in France, he brings a rare mix of applied math, systems-level Rust development, and practical cryptographic research to accelerate Ethereum’s resilience.

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.
