Streamr Review – DATA ICO P2P Streaming Data Blockchain Coin Tokens?

Streamr tokenizes streaming data, allowing machines and people to trade streaming data on a decentralized P2P network. Here’s our Streamr review.

What Is Streamr?

Streamr aims to provide a complete system “to create unstoppable real-time data apps, even without writing code.”

Under today’s system, the data you produce is at the mercy of large corporations. With Streamr, data is kept in control of users, and users can sell that data however they like. The data travels through a decentralized peer-to-peer network. There’s no centralized marketplace. You’re conducting sales directly with other parties.

Streamr’s main platform is already up and running at The platform is running in a centralized environment, but will migrate to decentralized blockchain technology in the future.

How Does Streamr Work?

The Streamr ecosystem uses the DATAcoin token.

The best way to envision how Streamr works is to consider a self-driving electric car. For optimal operation, that car needs data from other machines. It needs traffic information from other cars, for example, electricity prices from nearby charging stations, weather forecasts from weather monitoring stations, etc. Streamr provides a single interface for real-time data delivery and payment, making data streams tradeable using the DATAcoin token.

The car can autonomously get the data it needs and pay for it. In turn, the car can sell the data it produces – like traffic data to other vehicles, road condition measurements to a smart city, and location information to advertisers. This leads to the creation of a “data stream economy.”

Streamr Features

Here are the key technologies at work behind Streamr:

Visual Editor:

Streamr’s visual programming environment makes it easy to create data-driven decentralized apps (DApps). Streamr seamlessly combines data streams, smart contracts, visualizations, and off-chain analytics models, so developers can start building with open data and templates. You can execute your processes in real-time on the Streamr Engine.

Streamr Engine:

The engine aggregates, filters, and combines raw data with other data to extract the information and value within. It’s designed to process a high volume of real-time data from IoT devices, financial exchanges, social media, and so on. Processes running on the Streamr engine can read from and write to blockchains.

Data Market:

Streamr’s developers describe this as “the app store for data streams.” It’s an open, decentralized marketplace where users can buy and sell data streams. The market displays publicly available data streams on the Streamr Network, including both free streams and commercial streams. Data producers and consumers make transactions using DATAcoins.

Streamr Network:

This is the core layer of the Streamr System. It’s powered by the DATAcoin token and provides scalable, real-time data delivery I a publish/subscribe pattern over a peer-to-peer network. The Streamr network is a low-latency transport layer for real-time decentralized apps, as well as data streams on the marketplace. Network nodes earn DATAcoin in exchange for the bandwidth and validation they provide.

Smart Contracts:

The Streamr Network exists above the blockchain to provide speed and scalability, although it uses smart contracts for security-critical operations, including DATAcoin transfers, permissioning, and network self-governance. Smart contracts are used on the marketplace as well, where they implement data stream licensing models (i.e. consumers and producers can setup an agreement through smart contracts to buy and sell data stream licenses).

The entire platform is built on Ethereum, and the first supported blockchain will be Ethereum. However, the ultimate goal of Streamr is to make it blockchain-agnostic.

Who’s Behind Streamr?

Streamr is led by founder and CEO Henri Pihkala, COO Risto Karjalainen, Founder Nikke Nylund, and Chief Design Officer Matt Innes.

The company is based in Zug, Switzerland.

The Streamr Token Sale

The Streamr pre-sale lasted between September 14 and September 17, during which you could buy 18.25 DATA for 1 CHF. There was a minimum contribution of 5,000 CHF and a maximum contribution of 75,000 CHF, with a 5 million CHF cap for the pre-sale.

There’s a total supply of 650 million DATA tokens, along with a funding cap of 30 million CHF. 65% of those tokens will be sold through crowdsales. 15% will be given to the founding team. 15% will be held by Streamr, 3% for partners and advisors, and 2% for community building.

The company has not yet announced a date or time for the main crowdsale. However, it’s expected to take place in September or October.

The token sale is not available to citizens of the United States, Japan, or Finland.

Streamr Conclusion

The Streamr platform is already up and running. You can access the Streamr Network, Engine, and Editor today by signing up at

The technical infrastructure is currently built off-chain using a centralized model. However, the company plans to migrate to the Ethereum blockchain in the future. The project will ultimately be blockchain agnostic, although Streamr will be the first supported blockchain.

The Streamr pre-sale was recently completed, with a general crowdsale occurring in the near future (a date and time has not yet been announced). If successful, Streamr will create a unique “data streaming” ecosystem where data producers and consumers can interact over data.
