    what it does

    What hysteria does#

    Most proxy tools rely on standard TCP-based protocols that are easily fingerprinted and blocked by deep packet inspection (DPI) systems used by ISPs and governments. When TCP connections are throttled or dropped on unreliable networks — high packet-loss mobile connections, satellite links, international routes — traditional proxies degrade to near-unusable speeds. Users trying to maintain stable, private access to the open internet need a solution built from the ground up for adversarial network conditions.
