Avalanche is an open-source platform for launching decentralized finance applications and enterprise blockchain deployments in one interoperable, highly scalable ecosystem. Avalanche uses Proof-of-Stake, which allows tens of thousands of validators to have a first-hand say in the system while consuming minimal energy.
Avalanche is powered by the Avalanche consensus protocol; for specific use-cases on Avalanche, the platform is made to be totally-ordered and linear; this totally-ordered protocol is known as the Snowman consensus protocol.
Avalanche was designed to be customizable, scalable, and interoperable. Everything on Avalanche is a subnet, and every chain is part of a subnet. Validators are required to be a member of the Default Subnet; all other subnets are optional. The Default Subnet contains three blockchains:
