Arweave is a new blockchain storage platform designed to overcome scalability, data availability and cost issues in blockchain data storage. This is what sets Arweave apart from most blockchain storage solutions. Arweave aims to be "the Internet's browsable home network".
Arweave is a distributed storage network built on blockweave technology, where each block is linked to two previous blocks. Arweave is not strictly a chain, but a more complex graph structure called Blockweave.
Arweave is developing a base network that will primarily host "permaweb". It is a permanent, distributed network with many community-driven applications and platforms.

AR is Arweave's native utility token with the following use cases:
Miner Rewards: Miners in the network earn AR tokens for mining new blocks, which requires them to store and contribute data. A wallet owner may be both a user and a miner.
Transaction Fees: Users wishing to transact on the block will have to pay transaction fees in AR tokens.

The protocol consists of the following main components:
Permaweb: A collection of interconnected documents and applications, all of which are permanent. The browser will have access to all data stored on the network. Because the Arweave network itself is built on top of HTTP.
Benefit Sharing Community: Arweave is developing an ecosystem to empower founders, contributors and users. Founders can connect with the Arweave community and issue profit sharing tokens to raise funds and engage with the community.
Content Moderation: Nodes are not forced to store any data. Therefore, storage is only guaranteed at the probabilistic and network level, allowing individual miners to enforce content policy by choosing which blocks and transactions they wish to store.
