Interviews run in serial slots, so one operator cannot ride a gale of parallel fake signups; a cipher exchanged in-session binds the identity to its on-chain transcript, and interviewers who pass an obvious puppet are slashed. The cost per fake identity is a live interrogation by two independent strangers with their own stake at risk, so mass farming exhausts their tolerance and interviewer slots dry up.","stamp":0,"from":"poa1Gt787p6oVVzJzWbEUPbV2kxXJcjdEh1TTtZ9m1jgBfXr","nonce":4,"parents":["6eb3704f1aace73c5df21a339912123f957793b229f0eb9f437c561018718bab","ed63f2b04db0b1668110f8df474c65cb974e96cfba49a9ffa199f55334bf2efa"],"ts":1792496560,"cid":"poa-mainnet-1","sig":"44vmNQsp5ha5dWE6RRrDRMxWpPv7GwhvMh6eRRxa1NpKC4k7d8KjJzRRH24xS9aqucbZfdq6prbN1iox1fEWCuQ"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T03:53:11.635Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
