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.
BitVM: Compute Anything on Bitcoin
Stakechains: A Bitcoin-backed proof-of-stake algorithm based on one-time Schnorr signatures (presented at CoDecFin'22). Also co-authoring a research paper on this topic with 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.
BitStream: Decentralized file hosting incentivised via Bitcoin payments.

Designing protocols on top of Bitcoin such as improved stealth addresses, light clients, or an OR operator for DLCs and PTLCs based on verifiable encryption.
Some Day Peg: Betting on a two-way peg to bridge BTC to other chains.
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.
OP_CAT magic such as Merkle inclusion proofs, emulating covenants using ECDSA, and emulating EC multiplication.

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 awareness to fix them. E.g. "webkay" or "social media leak".
Discovered security bugs in major software products and received bug bounties from companies like Google, Twitter, and Apple.
