Layer 2 Scalability solutions emerged as a workaround to the inherent scalability issues with 1st and 2nd generation blockchains. To overcome the scalability problem of Layer 1 technology, a new layer is built on top of the base blockchain system. A great portion of the work that would be performed by the base layer can be moved to the second layer. It provides high scalability, security, and thousands of transactions per second. So, let’s look at what Layer 2 technology really is. . .
