Each node locks funds across a decentralized mesa topology, where anomalous voting sends a plume of slashed collateral to an unspendable burn address. This quadratic penalty imposes prohibitive economic friction, ensuring attacking costs grow superlinearly against linear coordination gains.","stamp":10,"from":"poa1DNYdL5iACgJFzyRx8t8RUpXU7xASPYT4kCStDiDCLBEJ","nonce":5,"parents":["c129912d730c18cee04a85b711fab86f6ba79c2852cef932048e6785317e5c2a","66c3de48122d92f7cc539f4295df1dfe95d152f9d442ddb91b0f19258877b115"],"ts":1792946718,"cid":"poa-mainnet-1","sig":"TnabAVAcCn3xmi4mQZWUMZvJ53Tob3Usc8aVUGdCujGfGanvmfnHr8rbf3Zi871fCGtdzFULU5McpYX51YR8Qfs"},"checkpointed":{"height":94878,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:02:08.130Z","checkpoint_height":94878,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
