Linea in collaboration with key partners including Clique, Consensys, Gitcoin, and others, embarked on the development of Verax, an innovative attestation registry. Verax was designed to transform applications by providing a shared "data lake" for storing and retrieving attestations—verified public interest data—across multiple platforms. The goal was to create a scalable, interoperable solution that could be easily adopted by applications, enabling more sophisticated reputation systems and distributed identity systems.

As the inaugural issuer on Verax, Clique needed to implement Proof of Humanity to accurately distinguish genuine users from bots while safeguarding user privacy and data integrity, thereby establishing a powerful form of fraud resistance within the ecosystem.

Clique integrated its trusted social attestations into Verax, serving as the first light proof-of-humanity layer. Instead of relying on intricate and often intrusive traditional methods, Clique focused on social attestations. Metrics such as influence, average generated impressions, account lifespan, and other user contributions, when viewed in aggregate, provide a picture of genuine human activity. This approach is intentionally designed to be low-friction and non-intrusive, ensuring users engage with ease and allowing applications to seamlessly integrate this new standard for trust and integrity in distributed networks.
