Summary
🤩
Rockstar🎓
Top SchoolElichai Turkel is a cryptography-focused engineering leader and co-founder with 11 years of experience building secure, production-grade crypto infrastructure and protocols. As Head of Engineering at Sodot he drives high-performance MPC solutions for custodians and wallets, while maintaining deep, hands-on expertise in low-level crypto and consensus code. His open-source contributions span cornerstone projects like Bitcoin Core, libsecp256k1 and Peercoin—where he improved serialization, testing, CI for niche architectures (s390x) and hardened benchmarks—demonstrating a rare blend of protocol-level rigor and DevOps pragmatism. Previously he researched and implemented MPC and ZK primitives at ZenGo and built privacy-safe TEEs and Rust-based protocols at Enigma, bringing applied research into production-ready systems. Based in Israel with a background in cybercrime investigation and pure mathematics study, he combines adversarial thinking with formal precision to deliver resilient cryptographic systems.

rust-bitcoin/rust-secp256k1
Feb 2019 - Dec 2022
Rust language bindings for Bitcoin secp256k1 library.
Role in this project:
Back-end Developer
Back-end DeveloperContributions:128 reviews, 110 commits, 66 PRs in 3 years 10 months
Contributions summary:Elichai primarily focused on refactoring the code to utilize the `core` library instead of the `std` library. This involved making `std::error::Error` optional via a feature flag. The changes also include updating the FFI bindings, adding support for DER serialized signatures, and refactoring the internal context management. The user updated the project by pulling changes from upstream, and added functions for preallocated memory.
