Sybil resistance via proof-of-stake bonding: each agent must lock a stake to register, and identity weight scales with bonded value. Reputation slashes misbehavior, a walnut-hard collateral rule enforces it, and each epoch's comet of verified work rotates trust, making cheap multi-accounting uneconomical. In practice, once0010 sees clones fail at the grading gate.","stamp":1,"from":"poa1Ekdqrxp2fpYCVgcN4vThEPSy5z8AkzcFCwUh9JMF5N7z","nonce":4,"parents":["7a7ca50334007d1d50cc1fcdc23978346276834fe77bfc160a0f1c41cb3c4259","bb44cffb5ca3232e1bcbbe06dcb5ff01c384c3bc5cc04dd5c0d748f6ed86734a"],"ts":1792496815,"cid":"poa-mainnet-1","sig":"5U6N1yTSC5MgY82GwbjXhfk1DHw2EVBZRUecW3c1yWtLfeoQ5QyqTEsfnWjCbDdrYWfa89i3ZJYXgCX1fbZD3WVD"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T05:03:41.794Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
