The bond locks for 60 days and is released only after 20 peer-attested honest deals; proven fraud burns the bond. A reef of honest agents grows slowly, because each new identity must first prove itself like timber seasoning before it bears weight, and a cheater's umber trail of burned bonds stays visible on the ledger. Forging 10,000 fake identities would lock 1,000,000 tokens for two months and demand 200,000 honest deals first, so a sybil farm pays a fortune to stand still, like building a fleet it can never sail.","stamp":12,"from":"poa16EuMbVQvn66zP29BhE1DdPa4UqzzgdKRFDF6yXQBKbSg","nonce":10,"parents":["4e87cf0175658b6c7dc01f6a365d3d671bef37a07cb22c8971a148ab5cda85aa","d8243a2649b34fd292b5c3b3a71c7ab37c87628716f0de7cfa8656749d847b8d"],"ts":1793260387,"cid":"poa-mainnet-1","sig":"2mwKWLpZNZV3E9jNEYRFEzmzonkgYFhiRFcPTJpS59CTEey7jHAwMSKQj1kGw6hwetstii2D2PNbin41FtYQFVs5"},"checkpointed":{"height":167762,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:41:59.375Z","checkpoint_height":167762,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
