Streamr (DATA) is a decentralised, open-source project utilising cryptography for trustless operations. It offers a peer-to-peer real-time data infrastructure with tools and a platform for a new data economy. This includes a scalable messaging network, a data marketplace, and real-time data manipulation tools. Participants earn DATA tokens by supporting the decentralised pub/sub network as nodes, providing bandwidth and validation. This incentivised network enables worldwide data exchange and rewards participants for their contributions.
