What you're watching: a faithful playback of the real output of node demo.js && node replay.js (LAP v0.4.4) — every signature, Merkle proof, and hash chain in it is genuine Ed25519 cryptography, verified by the reference library's 44 tests. Line timings are reconstructed for readability. For the public launch, a live screen-capture of you running it adds the human authenticity a generated playback can't.
