description Arweave Overview

Arweave provides permanent data storage by creating blocks that are cryptographically linked across time. Users purchase carbon units to pay for these blocks, ensuring their data remains available indefinitely. It's ideal for archiving critical information and building decentralized applications requiring long-term data persistence.

help Arweave FAQ

How does Arweave actually store data permanently?

Arweave uses a blockchain-like data structure called a blockweave and requires users to pay an upfront storage endowment when uploading files. This endowment is invested, and the yield generated from it pays the network miners to store the data over decades.

What is the AR token used for on the Arweave network?

The AR token is the native cryptocurrency used to pay for data storage and network transactions on the Arweave blockchain. Miners are compensated in AR tokens for continuously replicating and hosting the network's data.

How is Arweave different from Filecoin or IPFS?

While IPFS relies on nodes voluntarily pinning data and Filecoin uses temporary storage contracts, Arweave focuses on one-time payment for truly permanent, immutable storage. Arweave's economic model is specifically designed to ensure data availability in perpetuity, rather than requiring ongoing subscription fees.

Can I store large media files like high-resolution videos on Arweave?

Yes, you can store large media files on Arweave, though it can become quite expensive due to the upfront storage endowment cost. Many developers use third-party bundling services like ArBundles to upload multiple files efficiently in a single transaction to save on fees.
