Arweave is a decentralised storage and hosting network that is dedicated to making data easily accessible and available. This means it stores files permanently across a network of nodes (computers) that is accessible via traditional web browsers. Originally named Archain, Arweave is built around its native cryptocurrency, AR. People are incentivised with AR tokens to store data. 

Files stored on the Arweave network are accessible through a regular web browser (I.e Google Chrome, Microsoft Edge) meaning people can access them without the need for a digital wallet or through a blockchain.  

You can buy Arweave (AR) with low fees and spreads on the Swyftx crypto exchange.
