Scalability

Abstract

In the previous chapter, we addressed user onboarding challenges, one of the two main issues for Ethereum mass adoption. The second of them, which we will tackle in this chapter, is scalability. The Ethereum network, as it is today, can handle about 15 transactions per second – this throughput must be shared among all Ethereum applications globally. This has led to single applications cluttering the entire network due to a spike in their usage to the point of rendering all dapps unusable for brief periods. In this chapter, we will introduce state channels and sidechains, two of the most widely used scalability solutions.
