What Is Avalanche?

Avalanche is a decentralized, open-source, and environmentally-friendly blockchain. It uses the Proof-of-Stake (POS) consensus mechanism to add blocks to the network, and its native crypto token is AVAX. Avalanche supports dApps and assets on the Ethereum blockchain.

Launched in 2020 by Ava Labs, Avalanche was designed to solve some of the limitations of traditional blockchains, such as what we call the blockchain trilemma. Avalanche uses several approaches to solve the blockchain trilemma. First of all, it is not made of a single chain, but of three built-in blockchains working together. 

  • Exchange Chain (X-Chain): takes care of creating and trading assets

  • Contract Chain (C-Chain): runs smart contracts

  • Platform Chain (P-Chain): coordinates between validators to add new blocks to the network. 

By splitting the work among different chains and having them focus on their own specific tasks, Avalanche is able to run more efficiently than a traditional single-chain network.

To increase the network’s scalability, Avalanche lets developers create custom sub-blockchains, or subnets. Subnets can be used to run specialized apps without slowing down the rest of the network or exposing it to security threats.

Avalanche is one of the fastest and most efficient blockchains. It can handle many transactions per second without sacrificing security or decentralization. Combined with its security, That’s what makes Avalanche a good platform for making fast peer-to-peer transactions and building efficient decentralized applications.
