Layer 2 blockchain solutions are protocols built on top of an existing blockchain (Layer 1) to enhance its scalability and efficiency. These solutions aim to handle transactions off the main chain, reducing congestion and lowering fees. They enable faster transaction processing and improved throughput without compromising security. Examples include state channels, sidechains, and rollups, which allow for multiple transactions to be bundled and processed together. By leveraging Layer 2 solutions, blockchain networks can support a higher volume of transactions and offer a better user experience, making them ideal for applications like Web3 gaming and other decentralized applications (dApps).
