Like other data storage projects, Arweave has a network of people who have available computer storage and use them to store the data of those looking for permanent storage solutions. They, however, do this for a cost-effective, single up-front fee.

The unique solution to creating this uncensored record for the future is the Arweave protocol which creates its own blockchain-based storage network, blockweave.

The software protocols that Arweave has developed allow it to not only scale to storing all of the data on the web but also to scale the one-off payments processed for adding the data (Storage Endowment; see below).

There are already a number of platforms that have been built onto the Arweave network:

• Permaweb – This is a collection of websites, decentralized applications (dApps), or just data, that is accessible from the current internet but will offer the benefits of permanent storage.
  As well as storing static files, the permaweb can also host full, decentralized web applications. These applications live independently inside the permaweb, governed purely by their own code.
• Smartweave – It allows users and developers to build programs whose execution is trustable and decentralized.
• ArDrive – An intuitive user interface that gives consumers easy access to ‘Pay Once Store Forever’.
  : Upload multiple files at once with a wide variety of file types including; video (mp4, mov, wpv), audio (mp3, wav), photos (jpg, png, tiff), vector (svg, eps, ai), documents (Word, Powerpoint, PDF), and more.
