The Ethereum ecosystem is relatively new and is constantly evolving at a very high rate. New services and platforms are being added to it every day. The system has its own limitations, which can be either due to the lack of platform maturity or some design choices that have to be made for a distributed system. There are workarounds for some of the limitations, for example, by using Oracle services to interact with an external data source.
The community is building new applications and protocols to help users and developers to get more out of Ethereum. In this chapter, you will learn about other Ethereum protocols that can be used in multiple scenarios, and various reusable applications available in the Ethereum ecosystem. This will help you in building feature-rich distributed applications based on Ethereum.
