Arweave is a novel data storage blockchain protocol that aims to provide permanent, immutable data storage at a one-time fee. This is achieved through its unique blockweave technology, which links each block to two prior blocks, increasing security and efficiency. Arweave is designed to host the permaweb — a permanent, decentralised web where users can store documents and applications forever. The AR token is used to compensate network nodes for storing data, ensuring the long-term sustainability of the network's data storage capabilities.
