Avalanche is a decentralized smart contracts platform built for the scale of global finance, with near-instant transaction finality. The Avalanche protocol, which differentiates its platform from others, employs a novel approach to consensus to achieve its strong safety guarantees, quick finality, and high throughput. AVAX, its native token, is used to pay for fees, secure the platform through staking, and provide a basic unit of account between the multiple subnets created in Avalanche.
