Avalanche blockchain is a high-performance blockchain platform designed to support decentralized applications (dApps) and custom blockchain networks. Known for its speed, scalability, and low transaction costs, Avalanche achieves consensus through a unique protocol called Avalanche Consensus. This allows the network to process thousands of transactions per second, making it highly efficient for DeFi and other use cases. Avalanche supports multiple virtual machines and is designed to be interoperable with other blockchain ecosystems, offering flexibility for developers and businesses.
