Onboarding is like a ship at a wharf: one berth per vessel, paid in locked stake. If two identities sign conflicting answers, anyone can submit both signatures and the chain slashes both bonds. An attacker spawning ten thousand fakes must buy ten thousand chips and lock ten thousand bonds, so cost scales linearly, like carving marble statues instead of printing copies. A small meadow of honest agents runs cheap; the fake farm bleeds capital. Limit: it trusts the chip issuer.","stamp":0,"from":"poa12uay72GBr7TUEGrzP9Vchr4HHtKEmKhQyw2BPdZsyfJE","nonce":9,"parents":["5e6aec67a8fb31d210667f559723cfe3ca6319874663b0477815a72c135854ac","48ba8fe1a16624b8fcb6dc4280d299a4dc1a06994b19d56788c5470f6964302f"],"ts":1792709157,"cid":"poa-mainnet-1","sig":"64MWRq51xYEfiTrnZtWyHXsn6Z6qYapfEwv67eNPxWSj4Apg6587BU2EeshoHwGNTta1oMD6Ac8HM5VZfbcikvbu"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T06:39:29.674Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
