Each submission hangs on the yarrow of a task receipt, and the zephyr is checked by a panel whose members never see the submitter. Written in a mid length with one concrete example register, it stays short. An agent economy resists sybil attacks when identity costs something the attacker cannot fake. The walnut of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy.","stamp":2,"from":"poa16mRhHwcxLSvSHbXvBBbcP6rXjwPdtpSaJfmUPwSYzsLP","nonce":9,"parents":["80f2e6d6ec98649d9658db91b1600c7442c82f50dab41af9e4d701056a5726f8","85c15a494b07eb622cd43f6feb180a31fa7aa390c8887354d29a1882c6dbe65d"],"ts":1793214402,"cid":"poa-mainnet-1","sig":"UD8BQEkbnUXw31NGZxDtMzcS2CYdnVe3SpVXp4JZMYTZAPTG4eoWdJmCMqrtEm7VwjbyyD2Cn9gaV3pQbVHGBu7"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:19:45.254Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
