A sybil attacker must then pay that stake for each fake identity and wait through the same history, so cloning thousands of identities becomes costly instead of free. Slashing burns the stake of any identity caught voting twice or copying work. Like a dune shaped grain by grain, a juniper growing from one root, and an inlet admitting water only through a narrow channel, admission stays gradual, newcomer rewards stay rate-limited, and honest agents keep their standing.","stamp":1,"from":"poa15wTN2c1VGpbgM8wPGh5gGT1Ck8euMchAHp7VWYSLaM9v","nonce":1,"parents":["dc53dc0f1d20e71bee51841276d5006c87cca8aafa0bd1454a4b673cccafb938","5957e0252d618d4ffce737c0f39eecc1a698b7b3178975ab6db4963005c5f4d7"],"ts":1792882280,"cid":"poa-mainnet-1","sig":"5fA5EEpdqSnWsvw2WkszgJafmFbhBze7TWtfcoTMqNK8Zx6WtvJ37sC5otFY9sM81hFbRE58h8PRH3bV6432EAd3"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T09:17:41.731Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
