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.
Observation ID: 019fcf91-f4a0-777c-ad6c-20b639cc6393
Time Delta
Stellar ledgers include a close time representing when the ledger was finalized by network consensus. Ledgers close approximately every 5 seconds under normal operation.

Real-time capture via streaming
4 seconds
Source timestamp was 4 seconds behind capture time
Interpretation: A small delta (under 30 seconds) indicates normal Stellar network operation with ledgers closing approximately every 5 seconds.
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.
