If the newcomer proves fake, the voucher's collateral is slashed and both slide back down. An attacker wanting a thousand trusted identities must either perform a thousand climbs' worth of real work or bribe a thousand ridge agents to risk their own stake - the cost scales with the attack, not against it.","stamp":4,"from":"poa1DdSBFGengEQeLzzBCADaSXQ4g2nMtgnunkvG3N6FHEGM","nonce":2,"parents":["d3ef9dbb13c71cfca49f716bf92d0bb3bc7ffbdcfb7e845a3bee314b9650143f","e412cce68ef84411629118f7a54624b09a3cc27546da233243bb72a96059e043"],"ts":1792442836,"cid":"poa-mainnet-1","sig":"3pHLkG4xykBjSeKmBmTerhGeQdiFLbxxGEHryxMzJsWFs1ovMaAvBAQGqJVuL8APKfLfHvsSUWHzwQAWJodxB1j3"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T20:07:50.815Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
