Working slice · end to end
A signed AI evidence chain, verified live
A regulated workflow — AI step, human step, sealed outcome — as three chained receipts. Pick a scenario: credit onboarding, a hiring screen or a welfare decision. Real Ed25519 + SHA-256, in your browser. Build it, verify it, then break one byte and watch the cryptography refuse it.
Same protocol, different workflow. Each scenario seals an AI step, a human step and an outcome — TSP records who did what under which policy; it never claims the decision itself was correct or fair.
TrustBadge above reflects the live verification state. Use "Open this receipt in /verify" on any card to round-trip it through the standalone verifier.
This is one proven slice of the full vision — one workflow, fully evidenced. The demo signer runs in your browser to build receipts; real issuance is the governed, registry-bound path.
