Avalanche is a highly scalable blockchain with three integrated chains: X-Chain for asset management, C-Chain for smart contracts, and P-Chain for network validation and staking. Its unique Avalanche consensus mechanism enables fast and secure transactions without a leader. With subnets, users can create custom blockchains for specific use cases, benefiting from Avalanche's overall speed, finality, and interoperability. Developers leverage this platform for DeFi, dApps, and enterprise use cases.
