Streamr is a data streaming platform built primarily using Ethereum smart contracts (although it is blockchain antagonistic). The streamed data from both machines and people can be traded peer-to-peer on the decentralized Streamr network. This single interface for the real-time buying and selling of data makes it easy for users to participate, thus creating an entire new economy for data. A visual editor is available to users, allowing them to create their own decentralized applications on the platform. The Streamr Engine powers these smart contracts and can read data from multiple blockchains at once, and the Streamr Network is a transport layer powered by users that get rewarded for the validation and bandwidth they provide.
Streamr DATAcoin (DATA) Ethereum tokens are used to pay for data on the marketplace and to incentivize those who power the network.
