The blockchain space is continuously evolving, and new upgrades to the ecosystem are very common. Layer 2 technologies are one such innovation. Essentially, Layer 2 is just a secondary framework or blockchain project that is constructed and established over an already active and working blockchain network. Through this approach, Layer 2 protocol help in combating the problems that arise when it comes to the traditional network, for example, slow speed of transactions and complication in scaling the ecosystem.  

Recently the popularity and hype around Layer 2 innovations have increased significantly and more and more users are adapting to these protocols, however when we choose from the several Layer 2 option available for us, we need to keep in mind important factors that can help us decide the strength of the platform. In the article, we will talk in-depth about 10 such top Upcoming Layer 2 projects that you need to watch out for in 2023.
