          • ### Stated Purpose of the Hyperledger Aries Project

            The mission of the Hyperledger Aries Project aims to create shared, reusable, interoperable, and scalable agents for developing critical decentralized trust solutions, including verifiable credentials and communication technologies. It is designed to be agnostic regarding DID methods, credential types, and communication protocols, with ledgers being optional. These agents will represent organizations, people, and things, capable of taking actions through direct interaction or subject-approved automation, fostering robust and flexible decentralized trust solutions.
