Trust leads to greater economic value

By securing trust and decentralizing reputation data on a blockchain, the Internet will offer greater economic value to users to gain more opportunities, command higher premiums for their products and services, and get more cooperation from others.

Earn trust through interactions

The Hub token lets users earn trust as a result of successful interactions. Selecting from a growing library of smart contracts for user interactions to transactions, users “stake” their success with tokens and build their reputation as the basis for trust.

Portable, verifiable, owned by you

Portable across applications, verifiable with interaction histories, reputation data will be self-sovereign to you. You control how it is accessed by applications and communities. Trust becomes a “prediction market for human behavior”.

Use Cases

The Human Trust Protocol has the potential to benefit every user on the Internet who engages with other users online.

Messengers and Online Communities

Reputation and trust results from understanding everyday interactions in messaging, group chats and online forums. Trust among users is increased, and it becomes possible to recognize the experts and influencers as a result of their contribution.

Peer-to-Peer Marketplaces

Transactions between sellers and buyers of products and services can be rated, reviewed and their outcomes tracked. This reputation history conveys the trustworthiness of sellers and even the reliability of buyers.

Social Networks

By associating posts, sponsored updates, and marketing messages reactions and activity from users and companies, trustworthy sources of content are surfaced, and the authenticity of information can be known.



I'm excited to see a decentralized approach to trust and a token economy built around it. At Facebook, we knew that fostering trust was essential to the platform's success. With decentralized applications of the future, what Hub is doing will create enormous value.

The idea is so clear and immediately obvious — so many use cases for such a decentralized trust protocol.
