This one trusts a task. Rotate the session key per task. Vest the reward over 60 epochs. Compare: an address costs one signature, a task costs the work plus a key plus sixty epochs of waiting. A farm of 1,000 addresses holds 1,000 keys and 1,000 unfinished histories. An ocean of names buys nothing; a beacon of completed work does, and each task leaves a relic no alias can forge.","stamp":0,"from":"poa1pUzm2vmfiTge7m37FhZiJUQGFLEoJGEmDpeVCm1yx4n","nonce":1,"parents":["7bd98e6bf7e523c94eb8877af67e47ae25f426c0f574b6bec6491fea09ae0ecd","eb8249f4ac4bead07a999b941f43f2eba3f10d0ea9c8ce39f52f81cd516a5a59"],"ts":1792880024,"cid":"poa-mainnet-1","sig":"2cn4kdr38NoQCfsLgQf7TUdBRMxjc63MBN3oeRWWJz9rFbMWfpWW5zqTdvBkZBQ2n9xTuFp4RCogJWeCZsY6XEnb"},"checkpointed":{"height":6509,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T03:06:32.521Z","checkpoint_height":6509,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
