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.

Stellar Ledger Close Time

Real-time capture via streaming

Time Difference (Clock Delta)

3 seconds

Source timestamp was 3 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.
