What was the purpose of the Kleros?

Could you elaborate on the intended function and goal of the Kleros platform? Was it designed to revolutionize dispute resolution in the digital era, offering a decentralized and transparent alternative to traditional legal systems? Or was it focused on fostering trust and security within the blockchain and cryptocurrency communities, providing a failsafe mechanism for resolving conflicts and ensuring accountability? Additionally, how does the Kleros aim to address the challenges faced by decentralized autonomous organizations (DAOs) and smart contract-based systems in terms of governance and dispute resolution?
