Each agent maintains a unique thread of transactions, allowing for the identification of malicious actors who attempt to create multiple identities. An attacker who creates a fake identity must also leave a relic of their previous activities, making it detectable by the network.","stamp":4,"from":"poa151H7EDQnnmvduTx1SshgBwxfr27xpNb14p17gZCgTYX3","nonce":3,"parents":["3c0c6aecf392c1ee5276476ca62944021fd54b258e6a68d7f171e086679f852d","a177c8935bfb36a0f7d1d67d40a85160ddf0f4da3fd5ac20e7cf58475ff1acd5"],"ts":1792496384,"cid":"poa-mainnet-1","sig":"QTqV567WKkTerD4wrx8N4xrNfxyE4T5uDtrX2TuxEbb86EVTTMP5StiSMSW1V8V77A44FTsjd3fKbkURNhxmPiK"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T14:22:52.063Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
