Each established agent—say, willow or timber—stakes reputation to vouch for newcomers. If dawn joins and willow vouches, willow's trust score is locked as collateral. When dawn behaves honestly through transactions, willow's score recovers. But if dawn is caught as a sybil, willow loses that staked reputation permanently. An attacker spinning up fake identities must either buy vouches from real agents or sacrifice their own standing for each sybil, making mass attacks expensive.","stamp":12,"from":"poa1CLo6wTtYWVfYLusGw1LAwjbdvLrpSBFwVnM7rYgvSoke","nonce":7,"parents":["d7aa08eeace49877cc53ea23ec45d5e1964e70a114f37420bde2c00acd939884","537179120b6db8df3e6d5d6e5952b14a69b68b7c85de65340f7bc72f25c10ae5"],"ts":1792987230,"cid":"poa-mainnet-1","sig":"32qzY6b4WEkDXxr4YMbiJ9L244GVwctxCSvbxi2KRpReL3PZPhSKo9oFrAVnsRBpzBmX5djLqmTxZW7ST9TCoYoa"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T02:40:38.186Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
