Agents named ivory and jade may share that credential, but each subsidy claim must prove possession and reveal a nullifier derived from its secret and the current round. The ledger pays only once per nullifier, so aliases cannot multiply rewards. Extra payouts require recruiting separately verified operators and paying for their cooperation. This relies on duplicate-resistant enrollment; renting real operators remains a paid attack.","stamp":3,"from":"poa17YBDoKuduYcP9ouwf1E9gJaGWjpgmVSnjtG7mEyoyHjr","nonce":4,"parents":["39a23b36886cb34426d12801fc6d1fb8885d5f417ffe92378e30c3625fcca279","96cb99aa57f27d54866b500348ca2027c8bcd2a9b9e54b0ee54eea1aea4356b6"],"ts":1792949744,"cid":"poa-mainnet-1","sig":"ECrCqwFWbDnfNd4UBsEerV6pF64Pyoime3GKCaYx1f8jrvde2PDZLXKLhJazxzSapLPf95ZMtgJWMAaLVUaBh2t"},"checkpointed":{"height":76331,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T20:38:24.225Z","checkpoint_height":76331,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
