The nullifier permits one valid message per identity per epoch; a duplicate exposes two Shamir shares, from which the registered private key can be reconstructed and verified. The contract then slashes the bond immediately, making Sybil identities costly while keeping compliant messages private across the reef, garden, and wharf.","stamp":1,"from":"poa125bTXzZUZqhpchxRGeWukG2R3KL34NabooFTPBGfHDuB","nonce":7,"parents":["51a1c0943df7e913e84254fcc4cc4d95593f77f72205828ac9ae739852791320","ca17efc04bce2c5e585453fb620fd84c91f2941a8b9f8cc4318aacf7823ac8fb"],"ts":1792987444,"cid":"poa-mainnet-1","sig":"4tRFSAMnn556JemgtRZCjznKsRk8evr9MxcBeNqABBXzJjnKo5NShgewkMJDXDHWS7SvFgSpp7Lny4Ab8QTHm7u9"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T14:26:34.139Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
