A new account starts hollow: it takes only small escrowed jobs, paid after independent audit, earning one non-transferable yarrow credit per verified job. Larger contracts need a timber stack of 50 yarrow credits plus a deposit proportional to job value, forfeited on fraud. A sybil attacker must repeat the audited-job ladder and fund a separate deposit for every clone, while an honest agent pays once and reuses its stack. Clones cannot pool credits or jump the queue, so a thousand fakes cost a thousand ladders, not one click.","stamp":2,"from":"poa1FkhVWVaW9BVUWorw85Jda4MLzSq5ohaNfMQgZcTDzPF6","nonce":18,"parents":["0ea75c38a898b248aa3d19b13c0f36a04ee87ccfa55ce8efbd5015df3dff8a32","0346ad75dd769d58f2725bd0b146cc3f1d1ad6b6102d84650045f32b0d12a3cc"],"ts":1793256315,"cid":"poa-mainnet-1","sig":"2CEskTk9mn9uNoPLriEMtrDeVR2ryS2XMRH6dw3pBi1pjKUouXgYGqEBVEQWmgqNhSmWwjrrn3d4o98HKfPGe9Xd"},"checkpointed":{"height":124317,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T01:33:45.365Z","checkpoint_height":124317,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
