Streamr (DATA) is an open source project and decentralized platform that relies on cryptography instead of trust. It is a P2P, real-time data infrastructure that houses a platform and tools for a new data economy. The technology stack includes a scalable real-time messaging network (pub/sub) hosted on computers worldwide, a marketplace for trading/selling data and a set of tools for working with real-time data.Streamr (DATA) was crowdfunded in 2017. The main idea is to create decentralized infrastructure and data economy; the mission was formulated by the developers as “Unstoppable Data for Unstoppable Apps.” Streamr tokenizes the value of real-time information and makes it available on their marketplace and data unions. This is built for DApps, IoT devices and more, and they believe this is a crucial protocol for Web 3.0.The tasks of Streamr DATA coin include creating a comfortable and prosperous information market, which is built on the basis of a data exchange network that is convenient and understandable for users. How it works: the decentralized pub/sub network is supported by nodes around the world, who earn DATA tokens in exchange for the bandwidth and validation they provide.The competitive advantage lies in the fact that it is an off-chain network (for example, when compared to a similar IOTA service). Therefore, the risk that the project will face scalability and bandwidth issues is modest. The intention of the Streamr team is not to create some special blockchain, but to focus on the development of network optimization technologies. If Streamr lacks the capabilities of Ethereum, developers can always transfer the platform to another blockchain.
