Our vision is to create the world’s largest network of verifiable, user-owned data.
User data is a $5T asset class, but the creators of this data see none of the value. With the rise of generative AI, this data exploitation has reached unprecedented levels. By leveraging cryptographic primitives, we seek to dismantle the walled gardens of Web2 data.
