Public trust
Trust that can be checked
An institution that certifies others must itself be verifiable. Material acts across the ecosystem are signed, hash-chained, and anchored on-chain, so the integrity of the record does not depend on trusting any operator's servers. Every claim below carries the endpoint or address you can use to verify it yourself.
Commitment i
The governance event chain
Material governance acts — admissions, seat assignments, committee charters, standard registrations, ballot outcomes — are recorded as structured governance events in a hash-chained log. Each event is Ed25519-signed and canonicalized, so the log can be replayed deterministically from genesis and independently verified. The event chain is served live by the IAASO authority service.
The signed, hash-chained governance event feed (structured JSON).
Deterministic replay from genesis — confirms the chain has not been rewritten.
Commitment ii
The UUAID transparency ledger
Identity, certification, and vault events are recorded in the UUAID registry's append-only, hash-chained ledger. Its verify endpoint confirms chain integrity and reports the current event count; the ledger's heads are anchored to Polygon so its history is tamper-evident against the registry's own operator.
Verifies the append-only ledger from genesis and returns its head and count.
Resolve any agent identifier and check its certification standing.
Commitment iii
Merkle receipts
Individual events can be proven to belong to an anchored batch without disclosing the whole log. The receipts endpoint returns, for a given sequence number, the Merkle inclusion proof that ties that event to a batch root committed on-chain — a compact, independently checkable proof of inclusion.

Commitment iv
On-chain anchors
The trust roots are anchored on the Polygon blockchain (chain ID 137, mainnet). The contracts below are the on-chain anchor points; anyone can read them directly from the chain to confirm the batch roots the ecosystem has committed to.
