What are Bitcoin Layer-2 Solutions

As Bitcoin continues to grow in popularity, its original design, which supports only seven transactions per second, often struggles with scalability. This leads to higher fees and slower transaction times. To combat these challenges, Bitcoin Layer Two (L2) solutions have been developed. These solutions enhance the Bitcoin network by processing transactions off the main blockchain, thus increasing transaction throughput while maintaining security and enabling new features like smart contracts.

Use the multichain Bitcoin.com Wallet app, trusted by millions to safely and easily send, receive, buy, sell, trade, use, and manage Bitcoin (BTC), Bitcoin Cash (BCH), Ether (ETH), and the most popular cryptocurrencies, including ERC-20 tokens on Ethereum, Polygon, Avalanche, and BNB Smart Chain.
