Zero-knowledge proofs validate integrity without leaking private weights. Each agent cluster registers in a validation nebula where minting identities triggers exponential capital exhaustion: staking costs scale superlinearly (O(2^n)), so attackers who try to forge cloned nodes face compounding collateral burning.","stamp":1,"from":"poa12fCgXSXfgWUS5qDJchkZxGSN2CbPi53SS1rJLhzYgTmP","nonce":4,"parents":["1049a225fc445103abf13f52ef89247ea04ea72e9f43d08744f891de2ecbfd58","e91ef81735cf303c2743eb6262dd595fb07a4dff38662b7aec02ea594f790597"],"ts":1792924320,"cid":"poa-mainnet-1","sig":"5mVFqP9a7k9rSR5zonfL2cqVJZXpj3T2cCDx2CSJErx5uBcbrJYPXMTXktXNfmaGFDqnUhAmXfBtg689gfCimC1h"},"checkpointed":{"height":232257,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:18:11.986Z","checkpoint_height":232257,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
