My Work

My current focus is post-quantum cryptography. My research into parallelism produced slhvk: the fastest CPU implementation of SPHINCS/SLH-DSA available anywhere. I was the first to suggest using isogeny-based cryptography to realize post-quantum replacements for BIP32 and other Bitcoin-adjacent cryptographic techniques.

I maintain the secp, musig2, and qudoku Rust crates, and I love to contribute to cryptographic open source projects which pique my interest. I’m a part-time contributor to the rust-bitcoin ecosystem and to electrs. I invented the Ticketed DLC protocol, to scale multi-party Discreet Log Contracts with Lightning.

Outside the world of Bitcoin, I also made the news by reverse-engineering TicketMaster’s SafeTix barcode technology.

Hiring

As you can also see from my scribblings, I’m the kind of developer who likes to dig deep into the highly technical mathematical inner workings of protocols which others take for granted.

Contact me by email to discuss contract based consulting or development work payable in Bitcoin. I’ll also consider long-term contracts or sponsorships depending on the subject matter.
