Avalanche

Avalanche is a high-performance, scalable, customizable, and secure blockchain platform. It targets three use cases:

• Building application-specific blockchains, spanning permissioned (private) and permissionless (public) deployments.
• Building and launching highly scalable and decentralized applications (Dapps)
• Building arbitrarily complex digital assets with custom rules, covenants, and riders (smart assets)
