Arweave
What Arweave is
Arweave is a blockchain network for permanent, decentralized information storage in an open ledger. Its stated uses include preserving important data and hosting decentralized web apps. People can upload files or create a homepage on the permaweb. The network sets transaction fees dynamically, and its documentation recommends checking the price endpoint near the time of submission. The protocol uses HTTP, so developers can access it with existing clients such as Axios, Fetch, and Guzzle. Listed client integrations cover Go, PHP, Scala, Java, C#, JavaScript, TypeScript, and NodeJS. Node software can be installed from pre-built binaries or built from source. The developer guide describes node roles for solo, coordinated, and pool mining, as well as VDF servers and validator nodes. Arweave describes stored content as timestamped and tamper-proof through the blockweave; integrity checks use transaction data in block hashes and recall blocks. Storage has a lasting consequence: once miners store data, there is no guaranteed way to remove it. The policy advises against storing cleartext personal or confidential information. Wallets hold private keys and let dApps request approval to sign transactions and data; wallet providers cannot recover lost key files. Arweave.app is an open-source web wallet and browser add-on, while Wander offers a mobile wallet and Chromium extension.
Who it suits
Arweave suits people seeking decentralized storage for important data or a home for a decentralized web app, and developers who want to work through HTTP clients or listed language integrations. Its storage model also suits users who understand that stored content may not be deletable and that lost wallet key files cannot be recovered by wallet providers.
What it does well
- Supports file uploads and permaweb homepages.
- HTTP access works with existing clients.
- Client integrations cover eight listed languages.
- Node software is available as binaries or source.
- Open-source Arweave.app wallet supports web and browser use.
What to know first
- Transaction fees vary dynamically with the network.
- Stored data has no guaranteed deletion method.
- Lost wallet key files cannot be recovered by wallet providers.
Limits
Transaction fees are determined dynamically, so the price endpoint should be checked near submission. Once one or more miners store data, there is no guaranteed way to delete it; lost wallet key files cannot be recovered by wallet providers.
Getting started
- Visit the Arweave website.
- Choose whether to upload a file or make a permaweb homepage.
- Check the network price endpoint near submission time.
- Use an HTTP client or a listed language integration to access the protocol.
- For node software, install a pre-built binary or build from source.
- For wallet access, use Arweave.app or Wander.
Verdict
Choose Arweave if permanent, decentralized storage or hosting a decentralized web app fits your needs, with HTTP access and multiple client integrations for development. Look elsewhere if you need guaranteed deletion of stored data or recovery of lost wallet key files.
Questions
