Apps that are decentralized or "dApps" use a public peer-to-peer network called "Blockchain." Most apps or apps that are focused on the Internet are clustered. Servers for these applications are either run by a single entity or by independent operators. By doing so, these organizations or specific operators have direct access to user records, and a single server failure can cause protection and operational errors. These are some of the key issues with clustered implementations:
The presence of a common point of failure;
Lack of transparency;
Monarchy, and the
Subject to net censorship.
