Recorded world event

This is a recorded simulation or world event. Its hash and any Merkle proof check stored bytes. They do not make this event a blockchain transaction.

Hashes

Offchain hashes stay on this page, in the canonical document, and in the JSON export. They are not explorer objects.

Merkle batch id

Merkle root

—

Merkle proof

This event is not in a Merkle batch yet.

No inclusion proof is stored for this event yet.

Leaf encoding is bytes32 in an OpenZeppelin standard tree with sortLeaves false. A valid proof matches the supplied root only.

Anchor read

This event has no Merkle batch.

No validated anchor transaction is attached to this batch.

This page reassesses the observation included in the export. It does not open a second RPC from the browser. Repeat getBatch on the recorded contract before treating the root as published. EventAnchor does not check the inclusion proof.

Download machine-readable export

• Recompute the SHA-256 of the chogos-event-v1 canonical document from event. Do not trust serverRecomputedHash or any status label.
• Compare that digest to storedHash.
• When previous and next are present, check that the live hash chain links match.
• Verify the OpenZeppelin standard Merkle proof: leaf encoding bytes32, sortLeaves false, against batch.merkleRoot.
• A valid inclusion proof means the leaf matches the supplied root. It does not prove the root was published onchain.
• When anchorObservation is present, repeat eth_chainId, eth_getCode, the transaction receipt, and EventAnchor.getBatch on the recorded chain. The embedded observation is one server read, not a proof by itself.
• EventAnchor stores roots only. It does not verify inclusion and it does not prove the event happened.
• For an nft.transferred row, compare chain 143, the Chog Genesis contract, transaction hash, block, block hash, log index, sender, receiver, and token id with the explorer log. chain_status confirmed is not that comparison. transferLog.matched is true only after a read-only receipt check matched.
• Do not send event data to a third-party hashing site.
• This export is data. Recompute the hash and Merkle proof locally. A matching hash is not proof that the simulation was truthful.
• A privileged database operator can still rewrite history and recompute hashes. An onchain root only detects that after the root was published.
• serverRecomputedHash is a convenience. Compare your own SHA-256 of the canonical document with storedHash.
• Do not send this export to a third-party hashing site.
• The database batch id is a UUID. The onchain batch id is the bytes32 in BatchAnchored. This export does not treat the UUID as that bytes32.
