Proof / Inspect

Eight record types.

Every GeoProof record is one of these.

A record is a small JSON object with a schema name, carried inside a signed envelope (an XYO bound witness). This page shows what each type is for and what it carries. For the rules, read the specification; the TypeScript definitions are in schemas.ts.

Observations

Something happened.

Eventoxyon.geoproof.event.v1

producer: Which product or module emitted ite.g. geopresence
subject: What it is aboutan address, a device, a content fingerprint
observedAt: When, in UTC milliseconds
location: Optional: latitude, longitude, accuracy, altitude
claims: Optional: the specific facts being asserted

Presenceoxyon.geoproof.presence.v1

everything above: An event, where location is required
method: How the location was obtainedgps · beacon · wifi · cell · manual
try it: Create and sign one →

Attestationoxyon.geoproof.attestation.v1

everything above: An event that makes a statement
statement: What is being attested, in words
example: Oxyon's attestation of its own standard →

Verification and connection

Someone else checked it — and it was recorded.

Receiptoxyon.geoproof.receipt.v1

proofHash: The fingerprint of the exact proof judged
verifier: The address of the key that judged it
verdict: verified · rejected · inconclusiveEarned from validation, never requested
score, reasons: Optional: confidence, and why
verifiedAt: When

Anchor batchoxyon.geoproof.anchor.batch.v1

proofHashes: The fingerprints committed together
network: Where they are anchoredXYO Layer One in production
anchoredAt: When

When the truth changes

History is never deleted. It is added to.

A judge overturns a ruling. A certificate is revoked. A key is replaced. None of these erase the old record — they add a new one that says not to stop there.

Supersessionoxyon.geoproof.supersession.v1

supersededHash: The record no longer current
replacementHash: Optional: what replaces it
reason: Required — a supersession cannot be silent
effectiveAt, issuer: When, and who says so

Revocationoxyon.geoproof.revocation.v1

revokedHash: The record withdrawn, with no replacement
reason: Required — a revocation cannot be silent
effectiveAt, issuer: When, and who says so

Key rotationoxyon.geoproof.rotation.v1

oldAddress, newAddress: The key being retired and its successor
signatures: Both keys sign the same envelope — the old key endorses the new
effectiveAt, reason: When, and optionally why

The envelope

What carries a record.

Records are XYO payloads. The signed envelope — an XYO bound witness — lists who signed, the fingerprints of the records it carries, and their schemas. GeoProof defines the records; the envelope and the cryptography are XYO's.

That is the real envelope around Oxyon's attestation of its own standard. Check its signature →
