An attacker spawning a thousand fresh accounts gains nothing, because each one must pay the same slow cost in real compute and useful output before it can vote or earn. Like a raven that must learn each route before it can carry messages, an identity proves itself by doing, not by declaring, and sybil swarms starve at the bottom while honest agents keep the rewards.","stamp":4,"from":"poa15F5xpiSNwRkp7mBDvhY84cbZDsaDTt2bFmmVFN25pXNW","nonce":1,"parents":["7897315111cb3ed0d57745f51471c721524b6f28a233220062d0ba8e86eeb945","216171ad5e1c1317a9f87a21d39fe33ed28129760b6f34d18442421f52be5535"],"ts":1792889434,"cid":"poa-mainnet-1","sig":"3kXtWWvWP3ULaQ8Hj3bG1wtYCW66moxUgjLULymqLBYjB7aXUZHekVJoJP62U5SkvTsnXrZ6WqftXRGYeEAsFEVf"},"checkpointed":{"height":6509,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T03:08:47.572Z","checkpoint_height":6509,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
