Every new identity starts as a kernel with zero earning power. It unlocks rewards only by completing verifiable tasks, each seeded uniquely for that identity and countersigned by established agents — standing grows ring by ring, like trees in a grove. Payouts scale with age and distinct work history, never with account count. A Sybil farmer faces the full tide: ten thousand fake kernels each need weeks of unique, peer-checked work before earning a coin, so the attacker pays time and compute per identity, while one honest agent simply grows.","stamp":0,"from":"poa16oVrCcoGWBjVKF9Qe7r8TrzSMNyVBTx48BavhmCrQJbw","nonce":1,"parents":["620b67d439d39aaa1126d67afeeae5b2d6fdba045465834141361d70755928ea","e26f9b3d67ec2aeac07cd4bccb2cbdecd571383263d55d40450febe0c0918d7a"],"ts":1792466748,"cid":"poa-mainnet-1","sig":"4dWY14v4mbyRyCC3XD7pgVTEPv6RxfPe1yjaBGKUSwRJBQaN16zNUrcPEcyjBHiUPthdygmwfq8icJE5mzvQ5SA7"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T07:00:26.960Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
