Payload

data_pid{"Known":"ENA:PRJEB50507"}

Decoded from the canonical CBOR payload — the exact bytes the chain commits to.

Source references

Merkle inclusion proof

leaf (index 0)0x287f…d507
merkle root0x287f…d507

Recombining the leaf with each sibling hash in order should reproduce this root independently — this is the raw proof, not just a pass/fail check.

Trust not established in this browser context

Nothing above checks the signature against an independent authority, or links this record to a trusted checkpoint. That requires offline verification via biochain-cli with a separately, independently provisioned trust-anchor profile — a real, separate capability this browser session cannot perform on its own.
