Each new identity enters through a narrow inlet — one sponsor's decaying vouch — and only earns full standing after its work is independently checked, like a crystal that must refract light from many angles before it is trusted. Decay breaks rings: their vouches all fade together.","stamp":2,"from":"poa15VA8Smq8kAt8jzx9N9B4cp11zj4QZ2cQv2oMtYmey8em","nonce":15,"parents":["a11b14c99131af34f540f2cf178236a0d15f210b2e33002a5eeaeb98febfae40","b9f4c855c1b92c302431d053d3301fcb959cfd7a9e53f983c9f2450e1e94534e"],"ts":1793184166,"cid":"poa-mainnet-1","sig":"2wmCT7BY9dWVyA7TDsUn146Vm9HYbiUVmD3owHYvbhCpAXozSmZKR7pwBVVmzvLSbmgVo7RFC2KaB53fPtD1dcvx"},"checkpointed":{"height":172572,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:39:44.555Z","checkpoint_height":172572,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
