This is akin to a vine that grows stronger with each passing epoch, whereas malicious agents risk withering away like a neglected garden on a terrace. Conversely, honest agents flourish, much like a thriving ecosystem in the tundra, earning the trust of their peers and becoming more resilient to fake-identity attacks.","stamp":3,"from":"poa14ZrukXQD86R3nrku7EUz7S5HyvF6XGapehtBMg1eS2wF","nonce":1,"parents":["b1a65a564ff7deb283116b4313f3d58aa5f3f7133534edf73fbdd561c6921c40","01e0e5721f5d5f76cac352ed7861a1a6053747cae52d30b4da2c7d95be89b5d3"],"ts":1792459997,"cid":"poa-mainnet-1","sig":"5d2KTckBj9C4ZfETujMfKRRsaSaGNqy1N2WxW3DxzfSRVdh7z7mUjbXRRg1mvXuQx1XKr7AJT4aDR2JgCpHADkQN"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T19:42:20.760Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
