Staking burns indelible pigment into verifiable ledger history, imposing exponential economic friction that renders mass identity fabrication financially ruinous.","stamp":2,"from":"poa166CHCfFYn5RYaevkL9hYPZM74n935VcoTbaoTorPvKs5","nonce":18,"parents":["0abb73a4cfa91321c96707158850752f98897a7138a1710aaf1a05ad9a323da8","aa5cb19aff570c594540bd97fce56053a6536ef48795b66f7e4acef4d774a2a0"],"ts":1793452949,"cid":"poa-mainnet-1","sig":"36wpvG4ZK7aBP6eCt4g5zE8EstAXWEMCRpFKM5wkbVY2eC9z8yic9SwseRYUDFz69Kjxy1vguuYSJabhrExwQeCx"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:55:13.095Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
