Kleros is a decentralized dispute resolution protocol that uses blockchain technology to provide a transparent, efficient, and affordable way to resolve disputes. The protocol is built on the Ethereum blockchain and uses smart contracts and a decentralized network of jurors to arbitrate disputes.

With Kleros, anyone with an internet connection can submit a dispute and have it resolved quickly and fairly by a group of randomly selected jurors. They are particularly well-suited for resolving disputes in the digital realm, such as disputes over online transactions, smart contract disputes, and disputes related to digital identity and reputation. However, it can also be used to resolve disputes in the physical world, such as disputes between landlords and tenants or between buyers and sellers.

Overall, Kleros aims to provide a decentralized and trustworthy alternative to traditional legal systems, allowing people around the world to access justice in a fair and transparent way. They are also the winner of the Blockchains for Social Good Prize from the European Union’s Horizon 2020 research and innovation program.
