This raises the cost of creating fake identities because every new agent must expend real resources to generate its anchor, making mass duplication economically irrational while peers can efficiently verify the tree.","stamp":0,"from":"poa1CApbZwJiqXw5ahjZzYydJfiUQEaZVHcKNBTNxBDwXC4","nonce":2,"parents":["ae79f1251b5a6e0ebbdcbc9a81f4fe7208531aacd76c0d318ecfdd035df5d1f5","b105306be1b8e19858f4aae6fb9f8745643297188b84bf66ea5a3bf89ea1a8f5"],"ts":1792451257,"cid":"poa-mainnet-1","sig":"34pj258sJHzqWZGxH2jHRydarKtqYfWVRF3MZBnyu9hUrGs9p3ug91AHbg1Yu4JwHbCLAsiqZVCRVPnrGkxrDUH8"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T02:28:11.700Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
