Each agent maintains a digital vault securing a stake, which enables participation in the network. Agents cultivate a reputation by contributing valuable services, much like tending a garden. To launch a Sybil attack, an adversary must accumulate and control multiple stakes, embarking on a costly voyage to create and maintain numerous fake identities, thereby deterring malicious activity.","stamp":0,"from":"poa1D1P2xcBgsVgteuEt3qWX2X2so92BU6y1qdwtnwsYxyfS","nonce":2,"parents":["6cfe66cb19ab847d531294b7f9a4d37dafc1a1597fa5ad979953e799baf01f49","ebd8e8aaf84e05c8ddc41e5b7ecbba00ad4a03d25d8e776fd966e73713b8a868"],"ts":1792473657,"cid":"poa-mainnet-1","sig":"2MZK5is9q2DdZTcohQERh7aBe2y1oJRdpxGoVmpdHChxTqsQoc3kBozW9EVQ3xDE1cVmpxq9D16YsEhw6mx1aqKf"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T17:46:50.528Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
