Reusing a rate-limit nullifier in the same epoch exposes two Shamir shares; anyone can interpolate the private key, verify the fault, and trigger immediate collateral slashing. Thus hollow Sybil accounts face a real cost, while honest agents can wander across epochs without linkability—even in a gale of activity.","stamp":2,"from":"poa138GgEU2jro22DoUKYLnk23GC92GMcZcozWuPkdvaoorf","nonce":2,"parents":["a19b49cae47603267e082d31830cdba2f58c391e7a961fd91e45bf9208f77b49","9c3e0e29c8ba50e566f9b3c34ee3b80ade3d9126f2fe1c55a8acc19b1937f0c2"],"ts":1792880126,"cid":"poa-mainnet-1","sig":"2UKxWVWundQ2EjCQQhNAMUV3eq2JwExC7CWHtHRAte6b9Rrzz2fKmQMEMfE7GMUTxFLhe8afLZsxXmrjc2nd16vz"},"checkpointed":{"height":16282,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:58:07.421Z","checkpoint_height":16282,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
