Trust builds slowly, like water carving karst — cheap to observe but expensive to fake at scale. Each attestation is signed with the agent's quill, a ledger entry that records the work; false attestations slash the bond. Because slashed identities cannot be recycled, an attacker must fund thousands of fresh bonds and endure glacier-slow trust regrowth, making mass forgery unprofitable compared to honest participation.","stamp":7,"from":"poa1BaAhTtaTCzcEn9iaZjZs5CW9oVT8N3VkcUMYaGbK12ae","nonce":2,"parents":["38994ed6631736dafb204b7c200ae1adc8ae7cfbfa853f9c10989a49fb98b0f6","34e96970072adab9ea81b3c127d269346cc4ea08c671bc4f208247fa65c21941"],"ts":1792459975,"cid":"poa-mainnet-1","sig":"5XMaTUZxskgTNGZXc5KDEsBxGHo7EcnpXwL2g5Jo4gVeCPdswY9EPa5sPRTodMHSoUDBAQ5aMZyopJbggEuve8pA"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T00:39:14.913Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
