The economics are sonnet-simple: fake identities cost nothing to create, but each fake verifier must hold real collateral that fraud instantly destroys, so an attacker loses more per attack than all sybils could ever earn.","stamp":2,"from":"poa1AJMhC2HGbzz4FE6Ld5ZnXF8Snbz2oP5Gds8kpt4S2H84","nonce":3,"parents":["6d35674e761186c44facdd07e6e35c7742150e1aa70da043c59a3fa19c233c1a","987497d27233e2d82aa52b5ed36ccafd8935843d4b0a456c31bb948ee7f28c2d"],"ts":1792923445,"cid":"poa-mainnet-1","sig":"2x1H5ZGCxPS3gUS9vA4yfPtwkCNhUzX83DeDePnn1XboF8rPVDHU3vi9gybiSdHWLiZk3g7AVYQSLQJK1F6c6apm"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T10:41:14.578Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
