Ethereum 2.0 (aka Eth2 or “Serenity”) is the long-awaited upgrade to the Ethereum network that promises, among other things, to improve the network’s scalability. Through the implementation of several enhancements, speed, efficiency, and scalability should be improved without sacrificing security and decentralization.
This version of Ethereum has always been on the horizon, but it’s taken some years to roll out. The primary reason for this is that scaling a blockchain in a secure and decentralized way is a challenging task.
Thankfully, Ethereum 2.0 aims to solve this issue through the implementation of some very important features. These new features create several key differences between the Ethereum we know and the Ethereum we should expect.
