Observation

Verifiable entropy captured from an external public source. The canonical JSON representation and its hash are used as input to the blockchain's Merkle tree.

{"hash":"000000000000000000002c6ec691feabcce32460cb51fa0ef5f399bfbe779c20","height":961228,"time":1785978855}

SHA-256 composite hash binding the entropy data, metadata, and signing key id. This is the value placed as a leaf in the block's Merkle tree, and the value covered by the signature below.

Time Delta

Bitcoin blocks include a timestamp that represents when miners claim the block was created. However, Bitcoin's consensus rules allow block timestamps to vary from actual wall clock time. This section shows the time difference between the block's timestamp and when Truestamp captured it.

Timestamp embedded in Bitcoin block 961228

Real-time capture via WebSocket

9 seconds

Source timestamp was 9 seconds behind capture time

Interpretation: A positive delta (block time ahead of capture) is normal and expected. Large deltas (several minutes or hours) may indicate clock synchronization issues with miners or intentional timestamp manipulation within consensus rules.

Signature Verification

Truestamp signed this observation's hash at capture. Verify the signature in any Ed25519 verifier using the observation hash, public key, and signature shown below. The active public key is also published at https://www.truestamp.com/.well-known/keyring.json.
