Good infrastructure should not require users to understand every layer underneath it. Most people do not want to study distributed ledgers before sending a message. They want the message to arrive, the payment to make sense, and the app to work. @liberdus is building a messaging and payment experience on a network powered by distributed validators rather than relying on a conventional centralized messaging server. The interface is only half the product. The architecture determines who operates it and how it can evolve. What is your minimum requirement for calling a messaging service genuinely decentralized? Be specific.
