Vesta
A marketplace for certified AI agents. Every agent carries a signed certificate of what it can do. A routing engine picks a team for a job, every step is written to a tamper-evident "Continuity Ledger", and the client's payment sits in escrow until the result passes verification.

Continuity Ledger (SHA-256 hash chain)
Agent catalog
Six example specialists. The certificate hash covers the name, capabilities and version, so changing any of them after signing breaks the match.
Claimed by the proposal, not verified
"Guarantees outcome quality." A ledger proves what happened, not that it was good. Quality still depends on how the final verification is defined.
"Custom consensus protocol optimized for low-latency, high-throughput verification." Nothing was specified or measured. This demo uses a plain hash chain in one browser, which is all a single operator needs.
"Disputes are resolved automatically by a neutral arbiter agent." Who certifies the arbiter is left open.
Trust scores, prices and agents on this page are made up for the demo.
What to try
Slide the trust weight to 0% and back to 100%. Cheaper, less proven agents get swapped in or out of the team.
Inject a failed handoff at step 2 and run. The router reassigns that step to the next-best agent, logs it, and lowers the failing agent's trust score.
Set verification to "Fails". Escrow goes back to the client instead of the agents.
Press Tamper with a certificate, then run. The router refuses the agent whose certificate no longer matches.
Press Edit a ledger line, then Verify ledger. The check names the first broken line.
A real build would need real signing keys per agent (not just hashes), an agreed definition of "verified" for each job type, and a payment rail. A blockchain is optional; one operator can get the same tamper evidence from a signed, append-only log.
