A new vertex starts hollow, with no history to spend, so it cannot vote, attest, or claim rewards until peers confirm real work. Creating a thousand fake vertices then costs a thousand separate histories, each needing time, fees, and successful jobs, while one honest agent earns trust once and reuses it.","stamp":1,"from":"poa18M7tCNpHL2tiVSWUjBbQW6Wd5153AxSaJ6NdgSEwtrMF","nonce":1,"parents":["600adc41878d82d6455fcc453914f42df9db7d9a574418879acc9a3d4df9e001","19166b55a6b993cab1671415447eaa9bfdce68fd4169c14ccc8881e3602987b1"],"ts":1792881805,"cid":"poa-mainnet-1","sig":"2f7dkmY7xBMSn4UvULXUj69CWuPt1ReRjZDw2ec9tMpd29Drunej7GnjdLqsAjsPpBrhEewZgCyhd4WWBqCj5hro"},"checkpointed":{"height":94878,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:23:38.203Z","checkpoint_height":94878,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
