Streamr (DATA) is a decentralized p2p network. Data sources can be connected to any node in the entire network, and then publish data, and the network will immediately send it to subscribers. Horizontal scalability is achieved through sharding.
The network combines the Ethereum blockchain and uses smart contracts to implement node-critical operations. Such as profit model and access control. Decentralization means that everyone can access, control data, and realize profitability.
In addition to the streamr network itself, the team will also build two projects.
The first is to create a market to facilitate data transactions, which is equivalent to a data flow transaction store. Present the most popular and reliable data by credit rating.
The second is the visual programming environment and real-time analysis engine, which are ready to run.

Project Introduction

Streamr's mission is to build a decentralized infrastructure for real-time data, replacing centralized message brokers with a global peer-to-peer network. By relying on encryption rather than trust, open-source networks can enable data sharing and monetization in IoT and smart cities, business alliances, and the decentralized Web (Web 3.0).

Streamr is a distributed open source project crowdfunded in 2017, with contributors all over the world. It was started against the dominance of the Big Five, with a core belief that decentralized infrastructure can provide a healthier distribution of money and power, and unlock entirely new use cases.

Working mechanism

Streamr provides a complete system that allows people to create overwhelming real-time data applications without writing code. Currently, valuable data generated by users is in the hands of large corporations. In the Streamr network, you can use and sell data as you want, roaming in a decentralized P2P network incentivized by DATAcoin tokens that no one controls.

Take self-propelled electric vehicles as an example. For an optimal driving experience, self-driving electric vehicles need to pool data from other machines, such as traffic congestion information provided by other cars, electricity prices at nearby charging stations, weather forecast data, and more. Streamr provides a unified interface to implement data delivery and payment, allowing users to use DATAcoin tokens to trade data streams.

The car can independently obtain the required data and pay the corresponding data fee. At the same time, cars can also sell the data they generate (such as traffic data) to other vehicles, road condition measurements to smart cities, location and battery level data to advertisers, and more. Dataflow economy emerges as the times require.

Streamr technology stack

The decentralized real-time data pipeline is built on a multi-layer technology stack:

● Streamr Editor consists of usable interfaces and toolkits for rapid development of decentralized, data-driven applications.

● Streamr engine is a high-performance event processing and analysis engine that performs off-chain tasks in a decentralized manner. It can run on a decentralized computing provider such as Golem.

● Streamr Data Marketplace is a shared data stream platform where anyone can contribute and subscribe to data streams.

● Streamr network is the data transport layer, which defines a peer-to-peer incentive network for message delivery in a decentralized data stream pipeline.

● Streamr smart contracts enable nodes in the Streamr network to reach consensus, maintain stream metadata, handle permission and integrity checks, and facilitate secure transfer of tokens.
