What is a layer 1 blockchain?
Résumé
A layer 1 network refers to a core network, such as Bitcoin, BNB Chain, or Ethereum, and its underlying infrastructure. Layer 1 blockchains can validate and finalize transactions without the need for another network. Improving the scalability of Layer 1 networks is often difficult, as we saw with Bitcoin. In response, developers are creating Layer 2 protocols that rely on Layer 1 networks to provide security and consensus. Bitcoin's Lightning Network is an example of a Layer 2 protocol. It allows users to freely transact before recording them on the main chain.
