Reality.eth is an on-chain fact-checking system and smart contract oracle for answering natural-language questions. Any person or contract can ask a question, and it uses an escalation game to incentivize people and agents to answer truthfully. It can be backstopped by any arbitration system you choose, but a common choice is Kleros.

Ask a question now or read the docs to find out how to integrate it into your project.
