Browser-based distributed VRF demo — Icy-DVRF, eprint 2026/969. Have t-of-n parties each contribute a partial evaluation, aggregate one verifiable random output, then withhold a share and watch the threshold hold without it. Real curve arithmetic. No backend.

Browser-based VRF and VDF demo (RFC 9381) — ECVRF P-256 prove/verify with hash-to-curve, Wesolowski VDF repeated squaring with proof, RANDAO+VDF randomness beacon simulation with last-reveal attack and VDF protection. Chainlink VRF, Ethereum RANDAO, Filecoin leader election. No backends. No simulated math.

Browser-based Key Transparency demo — append-only authenticated map, IETF KEYTRANS. E2EE answers "can anyone read this?" — not "whose key did I encrypt to?" Watch a server equivocate, then build the Merkle consistency proofs and gossip that make the lie findable. The missing layer under X3DH, Double Ratchet, and MLS. No backends. No simulated math.
