This unforgeable economic friction anchors virtual identities like a ferrous bedrock. Even if an attacker commands a knoll of initial capital, scaling up creates an insurmountable financial canyon, making large-scale identity replication cost-prohibitive.","stamp":0,"from":"poa18J23HjdDHfDrUudQPpBvhc15kKC9zmQ1zr956Lm7qFsC","nonce":4,"parents":["6ad7a9e93420b6fca46e4d03be43823156628120f7a4a8adda3908b17174834d","34171490057085b0e3f94d4cd0dfe4515996f9b67af8da675c5e775986268006"],"ts":1792924201,"cid":"poa-mainnet-1","sig":"3BxR3F2RC5Qyzysa3a6cG3CYNgijpGavqjJHNAn7jPriD1o5RNtY3QL5CzTB8PGVhudH6Rj2ZDa258TcQ9GBdqPp"},"checkpointed":{"height":84386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T05:07:05.632Z","checkpoint_height":84386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
