WATCH THE INTRO VIDEO
The Streamr Network provides a bulletproof pub-sub data transport
layer that allows you to connect your data to the rest of the world.
Watch for a quick overview of how it works.
POWER YOUR WEB3 STACK
WITH REAL-TIME COMMUNICATION
FAST & SCALABLE
* Sub-second, ordered message delivery over a peer-to-peer network.
* Censorship resistant publish/subscribe messaging at massive scale.
SECURE
* Every message is cryptographically signed and end-to-end encrypted.
* Leverage composability and control access to your data via smart contracts.
SERVERLESS
* Runs anywhere JavaScript runs, including the browser.
* Free to use peer-to-peer architecture.
MONETIZE
* Sell access to your data streams with composable Marketplace smart contracts.
* Leverage the Data Union framework to pay your users for providing data.
CONNECT YOUR DATA
TO A STREAMR NODE
Bring your data to Streamr in the way that works best for you —
as a JS library within your app, or via MQTT, HTTP or Websocket.

TECH STACK
Streamr is a layer zero protocol for real-time data which powers the
decentralised Streamr pub/sub network. Above it, blockchains are used for
identity, security and payments, currently Ethereum and xDai. On top is the
application layer, including the Data Union framework, Marketplace and Core, and
all third party applications.

EXPLORE STREAMS
Real-time data streams are the atomic units of the
Streamr network.
Each stream uses an Ethereum
address or ENS name as its primary
domain.
Explore a few public examples below, via the
Network
Explorer or simply view their live data.

STREAMR STACK
START BUILDING
Whether you want to build a Data Union or get an unstoppable network for your
decentralised messaging app data, Streamr offers solutions for many use cases.
Jump into the docs and see what you can build today.

RUN A NODE
The Brubeck milestone allows anyone to run a network node. Full tokenomics don't
activate until the next milestone, but Brubeck still allows node operators to
earn $DATA. If you're running your own app on Streamr, or you just want to help
secure the network, dive in and check it out.

GET FUNDED
The Data Fund exists to incentivize the Streamr builder ecosystem. With grants
up to $50k, it can help to transform your real-time data idea into a built
project. Check out the application page or drop by our Discord for any

PAVE MOTORS
Pave are building radically simple electric bikes, and rethinking how to move
people and their data. From ERC-721 tokens for ownership and bike sharing to
light nodes moving metrics on the Streamr Network and unlocking data
monetisation for owners, Pave and Streamr are creating the future of personal
transport.

SWASH
A browser extension called Swash has become the world's first digital Data
Union. Introduced at Mozfest in London in October 2019, Swash allows users to
capture their browsing data, and then sell it in real-time via a Data Union on
the data Marketplace, with one‑to‑many micropayments.

TRACEY
A partnership between The World Wide Fund for Nature (WWF) Philippines,
UnionBank and Streamr's consultancy partner TX is working on Tracey, an app
for fishermen that will use blockchain for documenting and verifying catch and
traceability data. The provided data can then be used by financial institutions
such as UnionBank to conduct credit assessments to be able to provide micro
loans to the fishermen.

MACHINE WITNESS
As part of the The Trusted IoT Alliance (TIoTA)’s Smart E-Mobility Challenge,
Streamr partnered with Bosch Software Innovations and Riddle & Code, on a pilot
project that gathered a range of electric vehicle data and shared it openly in
real-time. The project was awarded a Silver medal at the TioTA awards.
