NOORCHAIN® · Public verifierOpen access

Verify an anchored period

Paste a period's manifest JSON (published by the organization). Its keccak256 fingerprint is recomputed here and compared with the PoSSRegistry registry on-chain. If a single character of the manifest changed, the fingerprint no longer matches.

Drop the period's manifest file here

or click to browse. The exact bytes of the file are verified: nothing is retyped, nothing is altered.

Paste the content instead (advanced)

Equivalent check without this page: keccak256(canonical_manifest_bytes), then call isKnown(fingerprint) on the contract with any EVM client.
