What is Scaling Solution?

A scaling solution is designed to improve the efficiency and computational output of a Layer-1 blockchain network. Scaling solutions are typically composed of Layer-2 protocols — such as sidechains and off-chain layers — that are designed to increase network transaction throughput and overall speed. There are many different types of scaling solutions including roll-ups, state channels, sharding, network interoperability tools, and more. Examples of Layer-2 scaling solutions include OMG Foundation, Polygon, Skale Network, and Lightning Network.
