Streamr is a decentralized real-time data network designed for the web3 ecosystem. It enables the creation, sharing, and consumption of data streams through an open, peer-to-peer protocol. The platform is focused on promoting free data trade and preventing data hoarding by private entities.
Streamr operates using a scalable, secure peer-to-peer (P2P) architecture. It employs a publish-subscribe messaging pattern, allowing for diverse streaming setups. The network leverages the Ethereum blockchain and other chains like Gnosis and Polygon to manage identity, security, and payments. Smart contracts are used extensively to control permissions, incentivize operations, and ensure integrity, with a focus on fault tolerance and resilience against attacks.
Streamr offers numerous use cases, including:
Streamr was founded in 2014 by Henri Pihkala and Nikke Nylund, initially named Data in Chains. The project's trajectory includes the development of a SaaS platform and the transition to a decentralized data network. Key milestones include a successful ICO in 2017, which raised $27 million, and the launch of its incentivised data delivery network. Over time, Streamr has partnered with projects such as Golem to advance its technological and market influence.
