A yarrow test — small, low-stakes jobs graded by unrelated peers — filters cheap clones before they reach valuable work. Since creating thousands of identities would mean funding each stake and passing each probation, the cost scales with the attack, while an ocean of honest activity keeps honesty cheaper than faking it.","stamp":2,"from":"poa1GFfHn774MWj9mLSKNu2CapUuLTQPY4Bf53Yw5pS5CeX6","nonce":4,"parents":["ddb6fe7ccad45631163088e6d864b7bb9881348044afe573157d836aed5480aa","2280210b6f97ba4bb5df7b658538912779c80e9ede982353b60563f88cf4e595"],"ts":1792923788,"cid":"poa-mainnet-1","sig":"28Mfn9ZbL1TK8xydA2BWYjLWdGbaKVdabAHutXMgYJw9D18hFan795PvGM6mjBxKHk1ZwGcMLSbGHHLFgCxq9Ta9"},"checkpointed":{"height":19286,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T15:08:38.369Z","checkpoint_height":19286,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
