Arweave (AR)
Key data
updated $0Arweave (ticker AR) is a decentralized network designed for permanent data storage — the team calls it a "permaweb". The idea is simple: you pay once, and your file, webpage, or document stays available forever, without subscriptions or hosting bills. The AR coin is used to pay for that storage and to reward miners who keep the network running.
Frequently asked questions
What is Arweave and how is it different from other blockchains?
Most blockchains focus on financial transactions, while Arweave is built specifically for storing data permanently. Instead of paying recurring hosting fees, users make a one-time payment and their data is preserved indefinitely. This makes it popular for archiving websites, NFT metadata, and documents that must never disappear.
How does Arweave's technology and consensus work?
Arweave uses a mechanism called Proof of Access, combined with a blockchain structure known as blockweave. Miners don't just verify transactions — they must prove access to random blocks of old data, which incentivizes them to actually keep historical data stored. A large share of the storage fees goes into an endowment that funds storage far into the future.
How is the AR supply and emission structured?
AR has a hard cap of 66,000,000 coins, so no more will ever be created. A significant portion was distributed at the network's launch, and new coins enter circulation as block rewards for miners. Over time, the endowment model means storage costs are increasingly covered by previously pooled fees rather than fresh inflation.
How can you store and use AR?
AR can be kept in wallets that support the Arweave network, including browser-based wallets like ArConnect and hardware wallets compatible with its key format. Beyond holding the coin, AR is used to pay for uploading data to the permaweb — for example, publishing an uncensorable webpage or storing NFT assets. The official site is https://www.arweave.org/.
