Avalanche is an open, programmable smart contracts platform for decentralized applications.
Avalanche a Layer 1 blockchain that allows users to build decentralized applications, smart contracts, and custom blockchains Avalanche has a unique architecture. The Avalanche network consists of three individual blockchains: the X-Chain, C-Chain and P-Chain.
Each chain has a different purpose, which differs from the approach of Bitcoin or Ethereum, in that all nodes validate every transaction. Avalanche blockchains even use different consensus mechanisms based on their use cases.
