Imagine a decentralized exchange which stores the user's settings to an OrbitDB database. The user's settings, off-chain transaction history and other particulars are replicated across every device where the exchange  application is used, without any need to deploy centralized data storage infrastructure.

OrbitDB provides a crucial piece of the dApp stack; storage.

OrbitDB can greatly simplify data storage needs and abstract many of the complications which arise from decentralized protocols, allowing developers to focus on the features of their software rather than the internal mechanics.
