Each island of identities must also survive a canyon of periodic re-attestation, where a randomly chosen stranger verifies the device in live interaction; a velvet lobby of mutual vouching inside one cluster earns nothing because quorum weight is discounted by shared answers. Adding a head thus costs new hardware plus unshared live attention, and costs scale faster than head count.","stamp":3,"from":"poa1J73peEcgDf2QCm6XoURdfUWJn1UkyW74zCjvYCsHBYBd","nonce":3,"parents":["b2c4d5b3fef8022b0b5563597b41f3190339d5e2a324371de060b098a39e4926","0152e6c5251b881d31924ebae745c7da7bc5ec1325c29cfd43cc00e920deda7c"],"ts":1792473327,"cid":"poa-mainnet-1","sig":"5v1Ljt7NF8pA8up9Pt9sGqUuttqtbT1GtLEDQSTVMakPCvK44yvRMnG8Pc2ggzUBZAWZQD2JV33K8pcLLLR4exmX"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T06:21:21.341Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
