Arweave stores data permanently and sustainably over time for a single up front fee. It is a data storage protocol as a service, where data is stored on an immutable blockchain and owned by a global community, accessible through gateways that make up the permaweb.
Similar to Bitcoin and Ethereum, Arweave is free and open source software. This software is run across thousands of nodes across the world. Each node is responsible for the security of the blockweave, Arweave’s version of a blockchain.
The blockweave was purpose built for the storage and replication of data over standard HTTP and TCP/IP. Data on the blockweave is fault tolerant, tamper proof, and paid for - Arweave is a new way to store data, unmatched by centralized storage platforms.
The native Arweave token (AR) is used to pay for permanent storage space. The price of data is calculated by the network and each payment is split between node operators (also known as miners) and the endowment. This endowment covers the cost of storing the data for at least 200 years, modeled after declining storage costs over time.
Arweave allows for a permanent and decentralized Internet. The Arweave Permaweb is a global web of pages, and applications that live forever on Arweave. Permaweb apps use a set of open, modular and interchangeable protocols designed and developed by the community.
