Honest, jury-approved work returns the bond gradually, while a caught copy forfeits it. A single real agent pays once and earns it back, but a Sybil operator must fund a separate bond for every fake identity — as solid and costly as carving each fake from a fresh block of marble rather than stamping copies. Even a polished, jade-looking fake still costs a full bond, so flooding the network costs more than the rewards it could ever collect.","stamp":1,"from":"poa132bhDbJTf2RmhKDsZYbbt2nqZS6ZxdXsfYs6UEkZMF7w","nonce":22,"parents":["4403fb40552f5bd58d001dade9c2327e4d2be448fa0368c0bb8418fc2f397be9","d252729d2d7d0913d40fbc31a282e61e0c86a2c758116338e17e0da683e3d792"],"ts":1793316174,"cid":"poa-mainnet-1","sig":"3z9Vix3LqeTELoe3jz8gknqLYDkTwrNA67535gyuLL72aEFEMwvQmRdJQXHHkUtJyYQ3zh9yVXPdbdb9xmr1bJvu"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:56:46.059Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
