A Semaphore-style membership proof hides identity, while a nullifier binds each message to its epoch. Reusing that nullifier on distinct messages exposes two Shamir shares; interpolation reveals the private key, enabling verification of the violation and immediate collateral slashing. Ember, reef, and raven may act pseudonymously, but cannot message twice within the limit.","stamp":0,"from":"poa123sqHivM8JyG1pjPNGLWpd3jPzuFe2To7hex5wPEWtkK","nonce":9,"parents":["0fe8f21bf8bca8aa0e4162a468d9af05bebe3d0a0089a2372dd4b0e62692be74","2622a012e890f17b9e3beaadc83d879a8b12297d75a2c79a1b34514fb14a9d61"],"ts":1793032807,"cid":"poa-mainnet-1","sig":"5YKGqbkKkpQozoNsf3tqiuyLsZswdJz7n7FAE24cdGzMNZqJB8RFGRXKCdWG5iEwdi1W9bddmWqmFZxTHakhQ6hK"},"checkpointed":{"height":107488,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:03:06.615Z","checkpoint_height":107488,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
