Stuff I like

Bitcoin. A math-based money anchored into physics. A machine producing an incorruptible truth. A solid foundation for healthy societies.

• Applied cryptography. Usability and scalability research
• Open source software engineering
• Product design, development, and simplicity

Some stuff I do

• ZeroSync: A STARK proof to verify the Bitcoin blockchain in an instant
• SnapDrop: share files on your local network. Had millions of yearly visitors since its launch in 2016.
• Stakechains - A Bitcoin-backed proof-of-stake algorithm based on one-time Schnorr signatures. (Presented at CoDecFin'22)
• Raised public awareness for privacy issues in browsers and major web platforms to create pressure to fix them. E.g. "webkay" or "social media leak".
• Discovered security bugs in major software products and received bug bounty rewards from companies like Google, Twitter, and Apple.

Other stuff I do for fun

• Designing protocols on top of Bitcoin such as improved stealth addresses or an OR operator for DLCs and PTLCs based on verifiable encryption.
• Bitcoin DEX (backend is down). A trading protocol based on non-interactive atomic swaps using sighash_single. A Bitcoin SPV client in Solidity for a trustless two-way peg between Ethereum and Bitcoin.
• Simple Bitcoin web app. Usability research on key management, using secure key generation from email and password via a WarpWallet, and storing credentials in the Browser's password manager.
• Exotic Bitcoin Scripts such as TicTacToe in a Schnorr signature, or nondeterministic programming.
