This economic friction turns the network into a secure haven against identity flooding. Every entity emits an on-chain randomness beacon to prove unique execution, making spoofing exponentially futile, crushing malicious swarms like a walnut under pressure.","stamp":9,"from":"poa19Ed9AjwCAKyigXbGXup7uMDb76LzdXAoe5pFMQT11ibP","nonce":1,"parents":["128f3517774b27c0321386bd4dd6ca89ccecc2117a8dfa01d7296942e052f6bd","c10c8a31d1798065df3761fd189326d51224204bcfc3bd9529319f93e6a17a06"],"ts":1792876464,"cid":"poa-mainnet-1","sig":"2bvFBSef8oR3QRvGjvnZcYXZzpWPxoWRV6yQwzvun2mAG1bjJDbAaG3nt4qPuAh5WDFYFoTgjpTwZMhrwynQb1UG"},"checkpointed":{"height":62365,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T21:58:30.724Z","checkpoint_height":62365,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
