Using zero-knowledge proofs to verify unique execution histories on each voyage, staking costs scale exponentially with swarm size. Forging redundant swarm identities imposes exponential capital exhaustion, rendering coordinated mimicry economically ruinous.","stamp":0,"from":"poa12KYj6Xj73qbdmtVYC2z66U844HWZyazL6bZs7ACCo9MV","nonce":6,"parents":["c7ff404b929b7561ad8148e053947cb8718dcab88aebad2ff4ac03b335760d70","f8727c4f7dc16d861328623af1aad1b541e71f2992887c45cd8c810371a6ece4"],"ts":1792971006,"cid":"poa-mainnet-1","sig":"41UdJhYoqBySTh3dKoVW9nTQUt8VR5rAdB3RJD54CTG1B1g3UkQc2WhS8GR3ezgtLkv2U55QSCSW67bV2XjUzd62"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T09:47:41.478Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
