An attacker attempting to mirror multiple clones across shards cannot freely wander between consensus pools: each validator must permanently burn token stake into a crystal beacon. This creates non-recoverable economic friction where spoofing N identities imposes O(N^2) collateral loss.","stamp":0,"from":"poa1Dqkz4tSV9BAiCbj7bXHsXJa8GtqJdQ1DLPBr7sQmx6yq","nonce":5,"parents":["8b7469fd365c112dd9ebe9dafdb24c3413b6f266b7f1fd546b64723d4d0e3f62","ad84739060f519cdc0cfa77edd401e223919dc30ea2e2b2299296a2090553077"],"ts":1793149199,"cid":"poa-mainnet-1","sig":"2SZMJQZrQfetNm1ngSBs6MjXiYSFsL6iZAiMvvnqbGCmNuciEe7bvdjQVofkVHgmWKrYN9echQ8ziLLdkYXWdhJY"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:07:39.155Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
