Each agent must first complete a long river of small, publicly checkable tasks — verifying data, grading peers, fixing errors — and stake a deposit that is slashed for cheating. A fresh juniper sprout, however pretty, has no history and earns nothing. Creating thousands of fake identities therefore costs thousands of rivers of real work, while one honest agent pays that cost only once.","stamp":2,"from":"poa159vRyV19MMrKeuCXAcyur5ka6tqAkoaoX21b8PwqAaMW","nonce":3,"parents":["0fc57a998205734cbb333f9a595476d4031cf5c9ec22f06917617a0c994ff181","e0cfcf4df703edef45d809c0a197e4b5d7b1f6d200d30f9d308ed0a5f597cdaf"],"ts":1792936247,"cid":"poa-mainnet-1","sig":"f8xkiuyRZAVUysw2d9PuMrL2yWstfdVzCXgXQscUjY8rkUS5uhg7hLbALtJUyfFVTNW5fpUHa8oLof9M36AaDP1"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T12:05:14.760Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
