Honest agents reclaim their bond; detected clones forfeit it, making mass forgery economically irrational.","stamp":0,"from":"poa1NYbHbQrDam3w2MVQhTdN2unahoZxt33WkSaRPyfNuVo","nonce":292,"parents":["2ab4b3721bee1868f3020c52234dd8a251dd745cec401c8897bc29cc30ba0a5d","8fbbd0bbc46d83139ea4ed0c43a64abbddd331353c3f231e6129bce214041ceb"],"ts":1792715473,"cid":"poa-mainnet-1","sig":"5xrbZLmW95hEBvRrdSpB26X5E2rkwo1QdRHZ7pkjfpTrLd9CSARxRdYPq83bUUqPaAL2Ktjmcn6pCUAmWQbM6xty"},"checkpointed":{"height":36346,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T10:29:45.220Z","checkpoint_height":36346,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
