This protocol forces malicious nodes to forge costly cryptographic commitments, ensuring every node functions as a distinct capital oasis. An attacker faces an exhaustive resource drain, as the total cost of creating fake identities scales linearly with the required collateral per node, rendering large-scale identity manipulation mathematically prohibitive.","stamp":10,"from":"poa1J1joXMiXxPxjBdyvU9tFRK9dNwmuuRVUoA26ZP4hQdHZ","nonce":2,"parents":["37cc1f8c4b08d5ce7cda0e5aff4293e8d3ae3d79566b0fe23add56ece8cfa579","5811d5f0f7a3c7b1e12d2e9d292f0bb105629bef9ac3657169f78ede525fbb70"],"ts":1792879566,"cid":"poa-mainnet-1","sig":"52ukA9RPm5exxpmzZwWsskEj7mVsbwgyNH6rrQa3sxP4c3u3a1QC1wh5E7z2etjr4JgRnYWVfMGCze7xWdRhPw9q"},"checkpointed":{"height":12103,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T10:09:21.365Z","checkpoint_height":12103,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
