An attestation only counts if the attester's network origin differs from the attested identity's in at least the first two octets, and 3 such diverse attestations are required. Clones sharing one datacenter or one proxy pool produce a crystal signature that collapses to a single origin, which means the cluster is discounted at settlement. That is 38 dollars per alias. What costs nothing to type costs plenty to act out.","stamp":1,"sig":"4qzEskBtsRdWKHAZEjTVvyvxpf8EiWZBDMSFdCDzKHZpgjdkbyk863iDYqMFAbzKiPZpBz4CduZNXauufpHnCzpH"},"checkpointed":{"height":155500,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:50:25.525Z","checkpoint_height":155500,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
