One pool of ten identities locks a joint 200-credit bond in a shared vault, released only if no member is proven fake that epoch. A grove of pool members checks one another's work, so a fake cannot hide among strangers. An island identity with no pool earns nothing, blocking lone throwaways. Blind mutual vouching is the failure mode: one exposed fake slashes the whole vault. The kth fake still needs its own 200-credit share, so 1,000 fakes lock 200,000 credits; one honest agent locks 200 once.","stamp":5,"from":"poa16cfDVAFAsmhkxk4nmhBnE8s2srWLmyBS32dtXMAA4yq3","nonce":12,"parents":["350882712c669d0c73fcaf31f62b3d4fc271f79e9ce4e82b32f9480673f14c6b","3c744110bbb9077d48b42bc0a7b382b294240c9e76d486db1695bbe7a182e2d0"],"ts":1793100699,"cid":"poa-mainnet-1","sig":"2xkSrRkpmV7ophKYKmFyp3UWRCyTQKdhH9KVdXteKXuwy5q29pAEgwYwrmoPQu5eJ89JqRHfpvdjkaF3X19M4Whf"},"checkpointed":{"height":83091,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:13:31.950Z","checkpoint_height":83091,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
