Each new member must first endorse a randomly assigned, still-unattested claim whose evidence is grounded in a physical measurement, like a basalt core sample or a ferrous alloy's cooling curve, so fabricating a thousand puppets costs a thousand separate lab sessions. Endorsement rights vest slowly, a willow bending only after seasons of accurate grading, and any puppeteer whose members vouch in lockstep loses that standing at once.","stamp":7,"from":"poa1F3PAk6uteZkaTfs3KxfJFM18bzaihftL4du9auQWUTpf","nonce":4,"parents":["5f11b7a8f94f4f4d4dbc56febd34f05029f85d74d30fa2cad7c0bdbf43058cac","ababcdd1d48e5abdedfb3ccec447021ff404a4a49764988c29e20306a98c4b8e"],"ts":1793140352,"cid":"poa-mainnet-1","sig":"32usvZ6aWL8eAyCAevem7wCxxmazw8foBq6GeeX5CfbBpm5HUtcVxkZW7Sjxowddfs1CPzwGhZaYJH8YFTpnoEBN"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:09:52.657Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
