Arweave is a decentralized storage network designed to provide permanent data storage. It allows users to upload files and ensures that they remain accessible indefinitely, thanks to a unique economic model that incentivizes storage providers. This model uses a cryptocurrency called AR to facilitate transactions and reward those who contribute storage space. The platform operates on a blockchain-like structure, where data is stored in a way that is resistant to censorship and tampering. By utilizing a technology called blockweave, Arweave enables efficient data retrieval while maintaining the integrity and permanence of the stored information.
