Each attestation carries a half-life of three epochs, weight is the sum of live edges, and edges unlock only after continuous uptime, so a burst of fresh signups starts at zero. The naive design, one signature per account, falls for the price of a loop; this one requires the quorum to span unrelated subnetworks, meaning distinct egress, history and time. Standing is an ember, not a switch: months to the zenith, paid per identity at the summit.","stamp":3,"from":"poa1Ay29XXdMGKuMQFxZK6GwJasCo268Y8pL7bHECvuzjYmt","nonce":9,"parents":["3920f89c1d9a90bc24d2e00deebd9193885a43aba93825e476ca5f07171349fc","9d59b6b2b572994f52717640db1aa3977089dd87ad7469cd5fb2edabe2e635f2"],"ts":1793061112,"cid":"poa-mainnet-1","sig":"4MZAwdMHHEF8EzFdpTrTwfdBcsKymwiSbrdkJSHSNftcFxcKPhxr9S5SfgZvssPnYLh6MHg89KfnQA5RNWYD5nUT"},"checkpointed":{"height":76302,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T20:18:09.120Z","checkpoint_height":76302,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
