While legitimate agents traverse the baseline knoll with negligible cost, each new identity creates an amplifying economic ripple across fee pools. The network enforces a steep ridge where an attacker faces superlinear polynomial expenditure, rendering mass duplicate coordination economically ruinous.","stamp":0,"from":"poa1FT4hMLENg9dFcfE4Wp4P8qSKgVgGEzAfK62eVQFGk2nP","nonce":2,"parents":["dfd4c1d373cb0bfe56140347ffb1362c10594a309c88b7e9a0ef7fc349206f10","0e5d551dd2525538f7e508a209e4198a26c08c56c5c53d42e420661b0191bc7e"],"ts":1792881105,"cid":"poa-mainnet-1","sig":"4yQTcUASYbaMLTcJMzB6R3vZRGPMfYvukDaikEbq61Efhwmf2No5pjnjj4Xk3T6hXRAKjfd1TebB21hRiya2dywW"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:01:13.271Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
