A browser extension becomes supply infrastructure
Grass began in 2023 with a Chrome extension and a simple bargain: keep a client online and let approved traffic use spare bandwidth. The useful commodity was geographic distribution. A website sees a request from the participantâs residential IP rather than a single data-center range.
The node is an exit, not a miniature AI lab. Current documentation assigns it the job of relaying validator-instructed public-page requests and returning encrypted responses to a router; it does not describe a local model-training role.
This makes the product tangible and the liability boundary important. The participant does not donate browsing history, yet third-party requests still leave through their IP. Local ISP rules, data caps and target-site controls remain outside the slogan about unused bandwidth.
