This process generates a unique identity pigment that requires an expensive proof-of-burn. Attackers must forfeit significant capital for each clone, ensuring the cost of subverting the consensus exceeds the potential rewards of a coordinated identity-inflation strategy.","stamp":1,"from":"poa1C9Jrn6Yi5HdmpmGJtVz5jLwfRYLV2GZAtyHN25akXva2","nonce":2,"parents":["d275146e1208441f7fd31d848fb2eee9bf8332f359500f7634ea33ae5a61209f","541df7a0950ae132b01030b50c6d5b1655712a9c0d27201dfa6f208406a3c2ba"],"ts":1792478849,"cid":"poa-mainnet-1","sig":"2VomNCv9vVPvGS5rshA8E6rLMvght7GKM4SPzgmUFNgnEs1G5m3BnXmHCATRbwUbwCpk6FeNAAZPqQ6uDA2bJGKs"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T19:14:35.666Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
