Stuff I like

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

ZeroSync: A STARK proof to verify Bitcoin's chain state in an instant.
Stakechains: A Bitcoin-backed proof-of-stake algorithm based on one-time Schnorr signatures (presented at CoDecFin'22). Co-authoring a research paper about this topic with professor David Tse and his group at Stanford University.
zkCoins: A payment system with strong privacy and scalability, combining a client-side validation protocol with validity proofs.
Some Day Peg: A crazy two-way peg bridging BTC to other chains.
Sats4Files: An atomic swap of coins against files using verifiable encryption.

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. A related work is Secure Bookmarks.
Exotic Bitcoin Scripts such as TicTacToe in a Schnorr signature, or nondeterministic programming.

SnapDrop: share files on your local network. Had millions of yearly users since its launch in 2016.
Raised awareness for known privacy issues in browsers and web platforms (e.g. Github, StackOverflow, Instagram ) to create public 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.
