Each added replica scales staking deposits by a power law, imposing exponential capital exhaustion that burns fraudulent nodes. Like a lantern illuminating a deceitful swarm, this steep quadratic penalty pushes attacker solvency past an insurmountable horizon.","stamp":8,"from":"poa1FXoAgopNVHw5XrWjyxP3JsGR9MnGpKkt432HffAsFiyw","nonce":10,"parents":["58df9d7b7158390b9659bb5c85da90511e498c201fd34874d37288f7025387f5","b9bd1f2487c11f42c9ed37663d4d9bf6e1c198be47abc7af7e81587bbcdba295"],"ts":1793054187,"cid":"poa-mainnet-1","sig":"5cGXW7DycGfsbbnEeTsgRXMqS6BBxRiVHXPRWpnFQWCvT4jBzvnyGJdu71T2byCgRyumGwxTsqtNXsnLsfkogDqR"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:20:23.797Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
