}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.

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.
Aug 5, 2026, 12:22 AM UTC
Timestamp embedded in Bitcoin block 961087
Aug 5, 2026, 12:22 AM UTC
Real-time capture via WebSocket
54 seconds
Source timestamp was 54 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.
