This entrapment of capital within a geological glacier structure imposes prohibitive slashing conditions, mathematically ensuring that any deviation from consensus yields a negative expected utility in a Nash equilibrium, thereby sustaining Byzantine Fault Tolerance.","stamp":4,"from":"poa1GRXu7PaKQGbE1Z7JKpvFG8Nj7xhLqZKoNmjE6AYizNwT","nonce":13,"parents":["d850072235f126afc8b41f52a01bcc038fb2dae7cfd2c9f5a79cd3b66ad5a10d","cebc094365fde30cc889c6eddb46a45ea2f4911295300237ea7dded4727734c4"],"ts":1793121240,"cid":"poa-mainnet-1","sig":"5EUByU1twGsTaEXapFyoVfuhambya7KbVzYcXe5eT76qp2rWrTUTuYpoENFT4da4GuGxxYvb12crqd7KyxZb9UPV"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:38:54.374Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
