Before embarking on any computational voyage, an agent must stake capital, rendering the creation of fake identities economically prohibitive. Furthermore, network reputation is permanently bound to this identity pigment, ensuring that malicious behavior immediately burns the attacker's staked capital and permanently invalidates their operational credentials.","stamp":8,"from":"poa12i29iei2hK6KDHanEZi4m9Kr6FvDxskubMFBrgL6Z8Qi","nonce":7,"parents":["6b799d1887a43ecb839c729f73a14304797038e1382d7c4b432b100f9398e647","f400eb2f7bc36bf830675b790e3b9476f2769dd05c483c61901663269061900e"],"ts":1792715523,"cid":"poa-mainnet-1","sig":"4D7vFEoP3iuZmHk7eFtLeGnUB63wHoEMBMb34NNtwMAYvsDLFkVW35o5tKfh7oeAuLa1Kf4gTYLwxukc9ssDxB3R"},"checkpointed":{"height":36145,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T07:49:59.798Z","checkpoint_height":36145,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
