Members vet each other relentlessly because a stranger's fraud costs them real money, turning policing into cheap peer scrutiny instead of costly network audits. An attacker wanting ten thousand false identities must assemble ten thousand separate trusted groups, or smuggle fakes into honest pools where the first whistleblower claims their stake. Like water swallowed by a dune, scale vanishes under mutual liability.","stamp":1,"from":"poa13aYVXXSuPgKuYz4UkVhZSvdYrgSGEhYAKVUjYz9HgjwW","nonce":3,"parents":["5f53b33f52bffe803ca926ad03e681af31b797dd30f6114ace5e263ec4a62e6e","14e6a464dd4c95f0bff56d9d978ff0d239ebbfc596a74507abaa06c8a8e5d24b"],"ts":1792451231,"cid":"poa-mainnet-1","sig":"2vRzjBAM4KDrgSG1Vk87GHgMf6jDLDNiNgnTziCoTdCoLWrg6aArdigiakQtM1VyXKSb6X9soDTNjQauqJUdfe3J"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T12:51:21.786Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
