03.2023 - 08.2023
- Bitcoin Core Contributor | Cryptographic Module Development
- Adaptor Signatures Module: Led the design and implementation of a full-featured Adaptor Signatures module, supporting key cryptographic primitives.
- BIP 340 Enhancement: Extended the BIP 340 Schnorr signature algorithm by introducing support for an additional elliptic curve point T, enabling the generation of pre-signatures critical to adaptor workflows.
- Algorithm Development: Implemented core adaptor signature algorithms such as adapt—which transforms a pre-signature tied to point T into a valid BIP 340 signature—and contributed to robust verification and extraction logic.
- Secure Transaction Design: Developed a privacy-preserving adaptor signature scheme facilitating atomic swaps and conditional payments on Bitcoin and Lightning Network without compromising private keys.
- Collaboration & Spec Writing: Worked closely with contributors to ensure seamless module integration. Authored a formal specification for BIP 340 adaptor signatures, complete with a reference implementation and test vectors.
- Privacy & Security Contributions: Strengthened the privacy guarantees of Lightning Network transactions and expanded use cases for Lightning-based applications through secure and standards-compliant cryptographic engineering.
