Summary
🤩
Rockstar🎓
Top SchoolSanket Kanjalkar is a Bitcoin-focused systems engineer with 11 years of experience specializing in Rust, cryptography, and zero-knowledge proofs, currently based in Seattle. He contributes to high-profile open-source Bitcoin projects—most notably rust-bitcoin, rust-secp256k1, and Bitcoin Core—where his work spans PSBT/segwit tooling, Taproot/Taphash support, Schnorr signature fixes, and robust test automation. His contributions touch both low-level cryptographic primitives and higher-level transaction and serialization logic, demonstrating fluency across protocol, library, and QA layers. Sanket’s background includes rigorous academic performance at the University of Illinois Urbana-Champaign, and he brings a minimalist, security-minded approach to Bitcoin engineering reflected in his GitHub bio and project choices. He’s comfortable navigating post-merge feedback cycles and maintaining backward-compatible Rust APIs, an uncommon combination of cryptographic correctness and practical engineering.

Open Source implementation of advanced blockchain features extending the Bitcoin protocol
Role in this project:Back-end Developer
Back-end DeveloperContributions:111 reviews, 38 commits, 10 PRs in 1 year 8 months
Contributions summary:Sanket implemented and enhanced taproot functionality within the elements project, focusing on advanced blockchain features that extend the Bitcoin protocol. They added Taphash, a critical component for taproot, to the test framework and made necessary modifications to the message structures for asset issuance and serialization. Further contributions include the implementation of transaction introspection opcodes and streaming SHA256 opcodes, improving the cryptographic capabilities of the project. Finally, the user addressed post-merge feedback and added pegins and issuance tests, ensuring the robustness and functionality of the codebase.
