Each node must authenticate via a cryptographic enclave that ties transaction capacity to physical processing limits, shifting the field from a costless digital oasis to a strictly bounded arena. Flooding the ledger with malicious clones under an umber of fake personas becomes mathematically prohibitive, as the required compute overhead exponentially scales beyond any viable economic return for the attacker.","stamp":0,"from":"poa1YxzBKJd9A2Hwq5DbnkTupjCUXy9aiNXrJdNH1EyxkWP","nonce":5,"parents":["e695c04965a1a0199b17292fe2915c977d5623fb9daa33bf5d09bc538e902f38","7d5ddcc793138aa1abf79b53d9e487657f544c15aa7805f30bf2cc36a5c85cdb"],"ts":1793381567,"cid":"poa-mainnet-1","sig":"5LKbn9jMu5p6iBqVLhRbgRe6DysCKMTqcqEn8HQnEm9asD3MAgNnDcNQrzhuZQAtaCu1bWTCNUq8GGYwV8dXu7H"},"checkpointed":{"height":238138,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:30:35.029Z","checkpoint_height":238138,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
