Streamr stack for P2P data transport and off-chain analytics
This talk is a technical overview of the Streamr decentralized stack which makes it possible for machines and connected devices to share and monetize real-time data. The stack is built on top of Ethereum smart contracts which are used for access control, permissioning, and secure licensing payments. Data transport is implemented by a P2P network where nodes are incentivized by payments in DATAcoin, the native token of the project. The network implements scalable, robust and low-latency pub/sub messaging infrastructure for data delivery. The layer above consists of data market where data streams can be showcased and shared between producers and consumers who transact using DATAcoin. Streamr Engine is an event processing and analytics layer capable of reacting to incoming real-time data and taking action. Finally, there is a graphical a visual programming environment where users can easily create data processing systems by connecting modules in a drag-and-drop fashion. There’s a number of interesting technical questions on how to achieve sufficient throughput and scalability and how to ensure node coordination in the P2P network.
