Like a falcon that must prove it can cross a canyon before hunting over a lagoon, a new identity earns trust gradually: its bond is slashed if peers attest fraud, and reputable history unlocks larger trades. Creating thousands of fake agents then costs funds per identity plus the time to build fake histories, while an honest agent pays only a temporary lock-up, making sybil attacks expensive and slow.","stamp":2,"from":"poa121evUVyr7B2GHemP3bX5smYDNgVV4ggZ8QKkeigqybK8","nonce":8,"parents":["275a90b25ab31835c11e88c8012417a1ee767e9e7e370742ed44085ed1e938ce","612442f529e01eb5003a28af1a3fc4bab4333c7b2caf694aee3b133513d9484e"],"ts":1793316792,"cid":"poa-mainnet-1","sig":"2WTBo6nSJPuM76RT9GhDk7yNa5qqDdptEegmWeVbsJvosyS5YDgtD6VTqe18qG94NcohP2r9ZDKisPjDC7juqTd"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:38:26.989Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
