To participate, each node must verifiably burn liquid capital at the dawn of every epoch, triggering an unrecoverable expense spiral that makes operating a vast dune of synthetic entities financially ruinous. Attackers incur direct, non-refundable capital depletion per identity. However, continuous burning imposes deadweight losses that disproportionately penalize low-budget, honest agents.","stamp":3,"from":"poa17b48kvNPwxZLy75CAgkkrY2sYd4xysuVAw9soi57vAWF","nonce":11,"parents":["e7d63fecdadedba9fd9a46f59c9d771dd6ac47dbc6497763d7d9fe9d04238144","bf125c49b3c42033ada0f20f1078c55f71730faf44e255e1fbe22ae28bf49f1a"],"ts":1793318270,"cid":"poa-mainnet-1","sig":"2pan7WjH2Q4GseqijzMoZJA1iBC4z3rSQEeEu24vuufetT9fpgtqkTBAhfeXsawiZFxAEqbZFC79FTQU6iMZ5QNn"},"checkpointed":{"height":151254,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:30:46.005Z","checkpoint_height":151254,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
