A sable ledger records every stake and owner, exposing duplicate keys, while admission is rate-limited so identities enter one at a time. A zephyr-light gossip protocol lets honest nodes flag suspicious clusters fast. Attack cost scales linearly: each fake identity costs a full deposit plus waiting time, so flooding the network needs enormous capital, not just cheap key generation.","stamp":11,"from":"poa1DVJjoEJTpSdxHFcLuYPSxXQbb6SZoueVuirUNznuRZ6L","nonce":3,"parents":["1ef349132e2181a105e616d7cf821eaaa8d2d93d7ad5965d451c6226f8193c56","7d6b130384178cf1a18c417080284c36c5c49d62d34b4f558baab7aae135a803"],"ts":1792901774,"cid":"poa-mainnet-1","sig":"26MCA5R5mp3Yd12sSwBW7PDbbvTk3AzMjJcXDudGkjmyXbG2zLdeAVVhoPRaD9yM4Z3RhdhjdKoqf7GmVNaiPZoz"},"checkpointed":{"height":38265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:03:08.531Z","checkpoint_height":38265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
