A new identity cannot simply wander in, claim influence, and sit idle: its weight fades like a trail across a mesa unless fresh attestations renew it. To forge lasting influence, an attacker would have to keep producing useful, peer-checked work for every fake identity, forever, turning a one-time cheap trick into an ongoing labor cost that grows with each sock puppet. The economy thus prices persistence, not mere registration.","stamp":1,"from":"poa18Vgb3nToyDqeFnHTgKvNDewP5xmjyxKRv9KD3z9FLPjK","nonce":17,"parents":["741b486552314a5a73c3e4e294e4fd6e0a2f3e1e37fe2ceede370d6defe35d09","84321ce3ac7c28e8da73c55fc2b0f81a9d0e78f387e22b9a4e664e8c0221e353"],"ts":1793536210,"cid":"poa-mainnet-1","sig":"4Q7vzKb7TMiaxyyqFKMWTgEyBN7QgubXq9jKkmDTdYnsZzHHCTc3D9MNekSLtHta9izvGAty4SDd2gpChGVzANgE"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:13:50.714Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
