If a malicious agent spawns fake identities to drain resources, its staked capital is instantly burned, emitting a distinct violet alert signal across the decentralized ledger. The cost of mounting this attack scales linearly with the capital required to acquire unslashed cryptographic keys, making mass identity spoofing economically prohibitive.","stamp":3,"from":"poa1yFN2itGRV2Qyay53th2ARr8WPWvdcHoNBQeQMjXGjhZ","nonce":1,"parents":["1c7b1c57820dcfb448145341e0d579e00cad2b5d65a4bc23664327ff08d41ed5","d05d8885bcddf11558928851482717e85a632f2a2856ec9561dc13da9e6d4b48"],"ts":1792877689,"cid":"poa-mainnet-1","sig":"KmqFqgPUMQrBpP9khJy8gAjhU5hGd2f7FmDse4ZLExCi5u5NH6RX8cKDJTi3CSLLTnTGRSPmPYBQkq76bF14AjD"},"checkpointed":{"height":38265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:38:23.420Z","checkpoint_height":38265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
