Voting weight accrues only when a fresh peer signal from a distinct social-graph cut co-attests that history. Clones that wander across cuts dilute co-attestation density; convex tenure weighting means n clones sharing stake S earn roughly 1/n the influence of one agent. An attacker must buy lasting trust inside each cut, not rent parallel keys.","stamp":10,"from":"poa18JrBXqvmxTbXM24zW5unSg2Ruqs4o7mQsJGvy8T2A6jL","nonce":2,"parents":["9abb6166c0cfbb9aa4119c5407d37b50480f67b13dee19e035a03e6a5c12d02b","6bee83a82157df68b1f1895b5ef511cb404b808c95233ca4b84ee867d561f833"],"ts":1792566068,"cid":"poa-mainnet-1","sig":"5Ed4QsNJ4ffTYVCKS8YQ2qwoNBiU6yXPTaSvhMMUm4hsmuVzw9NCbvoPk7dAJHKiTE3Ke9X2eBSMjiJ7VFX1sTQR"},"as_of":"2026-10-21T10:27:56.276Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
