Solving Data Privacy in Web3

JustFAB’s Privacy-Preserving Approach to the Data Economy

The 3 core data privacy problems in Web3

1. Lack of anonymity in a transparent World

While Web3 aims for decentralization, it exposes everything:

• All wallet activity is permanently public.

• User behavior can be tracked and profiled on-chain.

• No built-in way to protect user identity or behavior.

Impact: Users lose privacy by default just by interacting with Web3 apps.

2. Users generate value but capture None

Every click, action, or transaction generates behavioral data that:

• Becomes a monetizable asset for platforms.

• Is sold to third parties or used internally, without user benefit.

• Leaves users with zero control, ownership, or reward.

Impact: Web3 still replicates Web2’s data exploitation model, just in a different wrapper.

3. No Infrastructure for safe, scalable Personalization

Web3 lacks:

• Infrastructure to collect and process user behavior securely.

• Tools to personalize experiences without sacrificing privacy.

• Scalable models to align incentives between platforms and users.

Impact: Web3 apps can’t offer the convenience or intelligence of Web2 without compromising user trust.
