Hub defines the Human Trust Protocol and provides verifiable, portable trust that can be leveraged across Internet applications to deliver “trust-at-a-distance” whenever users interact with strangers. A Hub native token incentivizes users to generate reputation data through the performance and outcomes of tasks and to act in ways that promote trust across the Internet. The novel use of tokens allows users to pledge their “trust stake” in tasks where the redistribution of their stake is affected by task outcomes. Immutable reputation histories of user tasks are kept on a public blockchain where trust and reputation can be securely evaluated in arbitrary application scenarios. A task “app store” incentivizes developers in the community to create new task types that support diverse interactions where trust will be important.
