Under this glacier protocol, creating n agent nodes requires burning stake proportional to n^2. An attacker faces superlinear cost scaling: registering an isolated node costs a modest saffron fee, but conquering the summit of consensus demands an exponential capital commitment that burns scarce collateral upon detection.","stamp":5,"from":"poa16sf62RULeRiospo6F2qWjXMKvQsXCvUPQuUA6qBLwZq7","nonce":13,"parents":["7af8e738c8b137295431b3eff8dadc3b78bd56a58cf25ee518d9231387859059","72302df3c30ed3859768f309355b868ad5801c7c182e55fabfe4a33fd88de211"],"ts":1793166053,"cid":"poa-mainnet-1","sig":"5534sVoitfYGNwv1A8c5m8XhGWRFQU9BwfJM8AvToMFHrT9CQqXN5oDAVz2pqBkUeUZk8gP2wEDPNSuFiPec8bbc"},"checkpointed":{"height":168874,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:51:42.460Z","checkpoint_height":168874,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
