In a digital world where information is often temporary, Arweave introduces a framework for permanent and verifiable data preservation. It allows users to store digital assets such as documents, art, or complete web applications while ensuring that the information remains intact and accessible indefinitely.
What Is Arweave?
Arweave is a decentralized data storage network that allows users to make a one-time payment to store data permanently. Unlike traditional cloud storage systems that require continuous fees, Arweave provides a single upfront cost for lifetime accessibility. The network operates on a structure called the blockweave and uses a consensus mechanism known as Proof of Access to guarantee data integrity and permanence.
Founded by Sam Williams in 2018, Arweave has become a core infrastructure for long-term, censorship-resistant data storage.
What Is Arweave’s Native Token?
The AR token is the native currency of the Arweave network. It facilitates storage transactions, compensates miners, and supports the sustainability of the network. A portion of each payment contributes to the storage endowment, which funds ongoing storage costs as hardware prices decline over time.

How Does Arweave Function?
Arweave connects each new block of data to the previous block and also to a randomly selected earlier block. This structure, known as the blockweave, allows the network to verify and maintain data efficiently without requiring every miner to store the complete history. Combined with the Proof of Access system, this process reduces duplication, improves scalability, and ensures data remains accessible in perpetuity.

Who Can Benefit from Using Arweave?
Arweave is suitable for individuals, developers, organizations, and enterprises. It can store a wide variety of content, from photographs and documents to complete decentralized applications. The ecosystem includes tools such as ArDrive for storage & file management and BazAR for atomic assets creation. Developers can also use Arweave Wallet Kit for creating custom applications.

How Much Data Can You Store on Arweave?
Arweave has no fixed limit on storage capacity. As more users participate, the network becomes more efficient and the cost of storage decreases. The system relies on long-term trends showing that data storage costs decline steadily over time, making permanent data storage economically sustainable.
Can Data Be Edited or Deleted from Arweave?
Once information is uploaded to Arweave, it becomes a permanent part of the network. This guarantees authenticity and prevents tampering or deletion. Users may, however, request that individual nodes avoid storing specific content as described in the Arweave Standard ANS-106.
Comparison with Other Storage Protocols
Arweave differs significantly from decentralized storage systems such as IPFS and Filecoin.
- IPFS focuses on locating data through unique hashes but requires users to pay recurring fees to keep it accessible.
- Filecoin, which operates on top of IPFS, uses temporary contracts between users and storage providers.
- Arweave embeds permanence directly into its structure and economic model, rewarding miners for storing all historical data without the need for recurring payments.
Understanding Arweave’s Storage Cost
Arweave follows a transparent pay-once-store-forever model. The cost depends on the size of the uploaded data, overall network activity, and the balance between fees and miner rewards. At the time of writing, the cost of storing one gigabyte of data is approximately 10.80 USD. This single payment ensures that the information will be stored for at least 200 years, with multiple verified copies across the network.

How to Buy AR Tokens
Users can acquire AR tokens through cryptocurrency exchanges or on-ramp services. These tokens are required to pay for storage uploads and can also be used for ecosystem participation and governance.
