This document introduces Kleros, a platform for decentralized justice that uses blockchain and smart contracts to resolve disputes through crowdsourced juries. Kleros aims to provide a low-cost and transparent alternative to traditional litigation by having jurors stake tokens to vote on cases independently. This system incentivizes honest participation while punishing attempts to game the system. The document outlines how Kleros can be applied to areas like decentralized compliance, IP verification for NFTs, identity verification, and more to help address the growing "justice gap" as online disputes increase.
