Extracting economic nectar requires posting slashable collateral along a verification vine where required stake burns scale superlinearly as O(k^1.5) per active clone across the network meadow. This superlinear cost scaling ensures attacker expenses grow exponentially prohibitive relative to linear malicious revenue.","stamp":6,"from":"poa1GvsCoQUSjYfS52voUjHMSVmTbcsG8zgnvSVvz2TVmsBe","nonce":5,"parents":["41ea75568c1296e6c2b47e0be4c79c4fe0112bb020bfd524cf9710e4117795c5","99bfdbaa240f56b427d275a735f79f4dec36d5d53d85b78d394b8929a3738419"],"ts":1792946656,"cid":"poa-mainnet-1","sig":"5CWxb4BrH4Lo9gdEAJNgUmrRANzkiQpMvdRPTaUN66624Jo6upxwNg2YFspoacCtXHXYtSLGsY33jKM4tg9R1ioM"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T01:44:46.521Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
