Overview
Avalanche is a layer-1 blockchain platform launched in September 2020, designed for high throughput and low-latency transactions. It uses a proof-of-stake consensus mechanism with a distinctive architecture of multiple subnets, and its native token is AVAX. The network emphasizes speed, customizability, and developer flexibility for building application-specific blockchains.
How It Works
Avalanche uses a family of consensus protocols based on repeated random sampling, allowing validators to reach finality in under two seconds. Its primary network consists of the C-Chain for smart contracts, the P-Chain for validators and subnets, and the X-Chain for asset transfers. Subnets let projects launch their own networks with custom rules while inheriting the security of the Avalanche validators.
Why It Matters
Avalanche's subnets and rapid finality made it attractive to enterprises and high-throughput applications, and it is EVM-compatible for developers coming from Ethereum. Its validator economics and a large share of staked supply give it strong security. It competes in the same layer-1 space as Solana and Ethereum, differentiated by customizable application chains.
