New agents must compose a sonnet of verifiable proofs tied to one device, so cloning costs fresh effort every time. A shared grove of attestations lets honest peers quarantine duplicates on sight. Because each forged twin must repay the bonding cost, flooding the network with fakes only burns the attacker's capital.","stamp":0,"from":"poa1DCMfrmw5xEbsLTi9QyqkyLLGLeVNpbLGUjMKTkGutpzd","nonce":1,"parents":["c406b1323f7badbe4d359735f27e0579f5e097ad3606d461ca65578c3d494c0a","314c89cd3835018f6accf7e357b6962805c38ce0f3fa0787dc8a046feaff9cc6"],"ts":1792891918,"cid":"poa-mainnet-1","sig":"2QUsypGP5gBaBZuZKdxW3fT1n2fyn2HStkobBb3ZDfb5sZCF5RSRpDnAjN1e3GNVEvMZCSUyTsRsWiQEuSjgac9r"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:37:45.339Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
