News: Streamr launches Core app – News from Streamr

0 37


Free-to-use app gives developers and data scientists rapid insights and easy smart contract integration without needing to establish separate backend infrastructure.

Developers and data scientists working with real-time data will now be able to use an innovative free toolkit to leverage the power of smart contracts with complete ease.

Released today, the Streamr project’s open source app, Core, allows organisations who lack specialist Web3 programming skills to freely experiment with getting real-world events to automatically trigger monetary payments.

Core is seamlessly integrated into the project’s open data Marketplace and a dedicated backend data streaming network, so that programmers and data science teams will be able to fetch, push and sell new data products with total convenience.

Bypassing the need for specialist coding skills and complex data infrastructure, the new application is expected to save organisations days or even weeks of work when prototyping and testing new product ideas involving real-time data pipelines.

“Companies involved in industries like IoT, insurance, transport, social media and logistics should all find the Core app incredibly useful,” said Henri Pihkala, Streamr’s Co-Founder.

After a good number of months, with input from developers across four continents, we’re all looking forward to establishing a new way of working with real-time data that enables far more social sharing, easy smart contract integration, beautifully simple visualisations and proper Web3 integration.

Potential use cases include:

  • Linking Web2 data to trigger Web3 events: Streamr Core offers built-in modules to easily interact with smart contracts, deployed on the Ethereum blockchain, without any coding involved. With these modules, users will be able to listen to on-chain events, push data to smart contracts or bridge real-world events with smart contract triggers, via Oracles.
  • Gain insights into big data sets: Data scientists can quickly check and inspect data sources in real-time by connecting, for example, public transportation data and visualising this data as a heat map.
  • Ideation and prototyping: Create MVPs within your organisation without weeks of coding and the need to set up a backend.

Utilising a modular editing system similar to IBM’s Node-Red, Core’s inbuilt modules allow users to easily visualise their data and then share those results through social media on a live canvas.

Web3 sign-in and identity, alongside traditional email, allows decentralized accounts to ‘own’ data streams. This means that entities such as AIs, machines, or multisignature DAOs can control and benefit from Core app outputs, creating a paradigm shift in data ownership and management.

The app also offers rich developer documentation, smart guidance features on connecting and searching for modules, a stunningly designed user interface and nearly 170 modules readily available to cover most use cases.

Other useful modules include aggregate functions applied to streaming data to do real-time calculations and easy drag-n-drop charts creation, all of which immediately update as events are received.

Streamr Core also offers an advanced option for users to build their own custom module in Java, directly from the same UI interface, ready to be used on the spot, without any build or deployment requirements.

Developers and data scientists who would like to learn more can join an upcoming webinar taking place on the 4th of September. Further details will be announced soon on Twitter, Reddit and Telegram. Core app documentation can be found here: streamr.com/docs

If you’re attending Web3 Summit or EthBerlinZwei in Berlin this week Streamr Core devs will be available to give live demos on site. We will also be at a series of events.

  • Tuesday: developer workshop with Amber Data and Chainlink, diving into the details of the Core app.
  • Wednesday: developer Jonathan Wolff will present Ethereum canvases created with Core.

Both of those sessions take place at the Chainlink Hackernode at Web3.

  • Friday — Sunday: you will be able to find the Streamr team in the EthBerlin exhibition area showcasing Core.

With Core, there’s no need to set up a backend. Users simply log into the Core app where they can then create and manage data streams, and use visual programming to manipulate and visualise real-time data flows with a few clicks.

The underlying component powering the Core app is the Streamr Network, which is a peer-to-peer, decentralized, publish/subscribe messaging network. The Streamr Network is a set of open protocols for real-time data distribution and exchange in a decentralized fashion. In addition to the Network, the Streamr stack includes a Marketplace for data sharing and monetisation, and canvases for data processing and analytics as part of the Core web app. Users can interact with Streamr today using the Core user interface, SDKs, or directly via the API.
