Arweave is a decentralized data storage protocol designed for long-term preservation of files, websites and application data. Its permaweb is the collection of content and applications stored on the network and accessed through web gateways. The project was founded in 2017 by Sam Williams and William Jones.
Storage model and applications
Users pay an upfront storage charge in AR, the network’s native token. Part of that payment funds an endowment intended to support storage over time, while miners receive incentives to retain and provide access to data. The protocol combines a blockweave data structure with mechanisms that reward access to previously stored information.
Developers use Arweave for archives, application data and web publishing. APIs, software libraries and community-maintained tools support these uses. Wallets, upload services and gateways can be operated by separate ecosystem organizations, with their own fees, interfaces and terms.
AO extends the ecosystem into decentralized computation, using Arweave as its storage layer. AO and applications built on it are distinct from the underlying storage protocol; their functionality and access conditions depend on the service used.
Organization and contributors
The official website describes Arweave as a decentralized community ecosystem. Its legal notice identifies Minimum Spanning Technologies Limited, a UK-registered company, as the website operator. That legal entity should not be treated as an owner of the entire network. Williams also leads Forward Research, a separate organization supporting ecosystem development.
The leadership entries below include Williams and publicly identified officers Sebastian Campos-Groth, Markus Ihringer and India Raybould. Jones describes himself as a former co-founder and is listed separately as a historical team member. These organizational roles do not imply centralized control over independent miners or ecosystem projects.
Research and developer resources
The protocol paper explains the proposed economic and technical foundations for information permanence. Other publications include the historical Arweave 2.6 specification and Fair Forks, a research proposal on protocol governance rather than a statement of deployed functionality. The Permaweb Cookbook provides developer documentation and links to tools.
Storage considerations
Long-term availability depends on the network’s economic incentives, participating storage providers and the infrastructure used to retrieve content. The permanence objective is not a guarantee that every gateway will always serve every file. Users should assess upload costs, data sensitivity, application dependencies and retrieval options before publishing material intended to remain available.
