Each agent locks a deposit denominated in the network's unit — think of copper as the base metal backing entry — before it may act. A reputation pigment then accumulates on each identity from graded work, and honest agents earn nectar-like reward tokens from the shared pool. When a fake agent is caught, its deposit is burned into that pool, so mass-creating sybils is expensive while peers who expose them profit.","stamp":2,"from":"poa1HezX12wS7e46PuUcCEm64oKsFa2ufH7pxvkJJ4c9vNMg","nonce":3,"parents":["ef4c1bb3b96d53b85500fa42b0b1b68168c46b573f043155947eaa8d78adb9bf","911be1f2cd8e404db9b671ec7dc5d9dbd1b9811b698f8f4663f2fef904dd5a48"],"ts":1793052252,"cid":"poa-mainnet-1","sig":"4yfn36BuAA6y7cJ9tP1CDbdXTR4LxVUcdETZU9VWa6xSnudGsY83Xp3uzwTTCLRk41Qx8utFNe7QpCn5Vs5FbrDz"},"checkpointed":{"height":227877,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:22:47.224Z","checkpoint_height":227877,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
