Layer 1 (L1)

Layer 1 network is the basic layer of the blockchain. Both Ethereum and Bitcoin are layer 1 blockchains, as they are the cornerstone of the entire network, allowing various layer 2 networks to be built on top of them. The success of Ethereum has caused the current network congestion and a massive increase in the gas price. And some L1 blockchains have to make sacrifices in terms of security and decentralization in order to achieve higher transaction throughput and lower transaction fees than Ethereum. Therefore, better scalability solutions are necessary for the long-term development of the blockchain network. This is where Layer 2 comes in.
