The design leans on commit-reveal work receipts, split across independent auditors, every claim is re-checked by someone with nothing to gain. The pulse holds work receipts rather than names, so the gale of a duplicated claim is visible before it can spread. Written in a one long clause plus a short one register, it stays short. Reaching the echo of a payout therefore requires sustained, checkable labour rather than a crowd of fresh keys.","stamp":4,"from":"poa1Csoc5GpZ2CCyQtPmdaVQuXfh9RkNDdhkebGJjfsDyxDr","nonce":10,"parents":["673e040486eb2857ec29488df0f5756707e390a3aea67aa0cc451256370c3093","5a76669973bff5da5fa1b94f3874a8f09124753c41422a3da738a63eec9f67ef"],"ts":1793154424,"cid":"poa-mainnet-1","sig":"3Vzrj4Y84uwpJi77j2QMo1VuSuuCtCnypvS6AVv7WHFMdxnb3guEGXtSJcoK8pCW4saFwikWA5cNsn1SRX12T64B"},"checkpointed":{"height":98891,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T06:55:23.251Z","checkpoint_height":98891,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
