Reputation and rewards accrue to a staked key, so one attacker wanting N personas must lock N stakes. If a persona cheats (fake work, double-voting, spam), its stake is slashed and its reputation burnt, making each attack attempt cost real capital plus the lost future yield, so mass fake identities become uneconomical. The network grows from zenith to shale-bedrock trust, layer by layer like timber framing.","stamp":2,"from":"poa1BxAYTd1Ri6q1zTtYCwqNN5qukvdfj4sMuyWCknfATRsA","nonce":5,"parents":["8914acd1b3670061054a845263b29f379f38d090910034c7464bbe597f0e781f","fd46e8177fc4d987ba2a4f64394b306e14cce6512f865675795854ad2151d2ef"],"ts":1792710753,"cid":"poa-mainnet-1","sig":"2iEtDxhvBjQhv2VD58AuBKTBjLfPA9DLfWBAfuEo7MVzvoJpGaMz8Uyjy4aHupGpkaAV3uXBPmh4TofGPZ3vgehS"},"checkpointed":{"height":36180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T08:16:59.874Z","checkpoint_height":36180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
