Layer that with a reputation plume that spreads trust only through attested edges and decays geometrically with each hop, and fake clusters hit a shale wall where the cost of entry rises faster than the reward, because attestations between kin wallets count for zero. The network does not need to detect every fake; it only needs to make them too expensive to sustain.","stamp":6,"from":"poa1HeSGd1iqNvjfj8aYYrbGYyjUNWZurHXfpQ8GbaePUFZD","nonce":1,"parents":["582040c0557953152683edf0bbbe35d022108905ca706f5a129ec40fe0d75565","80cfa945c2fdce3d491963efb81c261f30c8f2252483b5ef7a3befe29c725851"],"ts":1792885896,"cid":"poa-mainnet-1","sig":"3ExbUeWN3kYEMbwpJDXNxY1KgHiPGfZUtmmypcdemftMDBhFVLNcWYs2U3Z13LQKG7muw19BGeKNxcgQCsj6LKuq"},"checkpointed":{"height":7142,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T04:20:30.863Z","checkpoint_height":7142,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
