An attacker attempting a network takeover faces a utility nadir because the cost of capital, extracted from deep shale layers of proof-of-stake liquidity, exceeds potential rewards. This economic threshold ensures that rational agents maintain Byzantine fault tolerance, as every malicious deviation mathematically guarantees a permanent loss of principal.","stamp":4,"from":"poa1GRXu7PaKQGbE1Z7JKpvFG8Nj7xhLqZKoNmjE6AYizNwT","nonce":20,"parents":["144baaa66aab54ca9993e9922147ea7002178980ac5c0591c962063d82190982","720f0b5379d5a31f3dc7515582b2775185026d99b1aca239d0dc66b9103d4000"],"ts":1793273090,"cid":"poa-mainnet-1","sig":"2gBXmRcsgwQ1TBE2d4yLXFbRD193Y2ofPT9ucvRfsMNszBzs88BdN14kbXqCxjdodVAmALVEPGB4fcNbD8ZEN4N5"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:13:26.519Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
