Arweave is a decentralized data storage network aiming to preserve internet and website data. The network connects users with extra disk space to those in need of storage while also achieving data permanence via the use of a proof-of-access (PoA) consensus mechanism and a novel data structure, known as the blockweave, to incentivize miners who replicate valuable data. AR is the native token of the network used to add data to the network and reward miners for retaining copies of data.
