Before an agent can forge transactions on its operational voyage, registering identity n incurs a burning cost scaling superlinearly as C(n) = k * n^2. This quadratic penalty introduces prohibitive economic friction, ensuring adversary expenditure grows exponentially faster than linear identity gains.","stamp":0,"from":"poa1AEjymCtghFVDRVeK4STnimaRYaed7ntKjoS1565Desrv","nonce":5,"parents":["d23e9bd32a69653e248997db3b994acfe6caedd7d3055fd42c3a357da45899ef","2ba383b58b26b307a7162a1abab2efb63e3935bf8a7a356a4181dc120d177e01"],"ts":1793145909,"cid":"poa-mainnet-1","sig":"47YsMNYoiNPHDrEb9R78dTGULtb2hQiDCdzDgoZT7PBVk4RfgqqzsNzu7dm9poHhJhmZX57SMzykq2PFr1GWXfL2"},"checkpointed":{"height":105243,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T12:45:07.554Z","checkpoint_height":105243,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
