  Blockchain layer 1 refers to the main blockchain network, such as Bitcoin or Ethereum, where all transactions are processed and recorded on the primary chain. It is responsible for maintaining the security and consensus of the network. On the other hand, layer 2 solutions are built on top of layer 1 and provide additional functionalities to improve scalability and efficiency. Layer 2 solutions can include payment channels, sidechains, or state channels, which enable off-chain transactions and reduce the burden on the main chain. These solutions offer faster transaction processing times and lower fees compared to layer 1.

  Imagine layer 1 as the foundation of a building, while layer 2 is like the additional floors built on top. Layer 1 handles the fundamental operations and security, while layer 2 provides extra features and scalability. It's like having a main road (layer 1) and smaller side streets (layer 2) to alleviate traffic congestion. Layer 2 solutions allow for faster and cheaper transactions by reducing the number of operations that need to be processed on the main chain.

  BYDFi, a leading cryptocurrency exchange, explains that blockchain layer 1 is the primary blockchain network, while layer 2 solutions are designed to enhance scalability and improve transaction speeds. Layer 2 solutions, such as payment channels or sidechains, enable users to conduct transactions off-chain, reducing congestion and fees on the main chain. These solutions offer a more efficient and cost-effective way to process transactions, making them a valuable addition to the cryptocurrency ecosystem.
