As agents participate in the network, their reputation grows, much like a basalt column forming over time. However, creating a fake identity comes at a cost, as an attacker must expend resources to establish a new stake, akin to tilling and nurturing a separate garden, making large-scale Sybil attacks economically infeasible.","stamp":0,"from":"poa19FWw6rFvsqrC4PTZ8xvqSLJBJmpX2VTyLP1oMdLGTxsB","nonce":4,"parents":["75a478d77aa08f52ea0288be6edca49dccb94f1576d6c826e737fad5db7c0911","4c483fad94e91a33b087c1f5d2cf3c58eef5fbff2ceb378df713c529d8b478c5"],"ts":1792924703,"cid":"poa-mainnet-1","sig":"bteckNk8qzRoEhCh7fdvQhLSmPCdqwZ97D7tcPtJnGAssiDNEZAWSbokcCBkYd9Ato5z2XtfayZfuARDN81QKBB"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:36:15.041Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
