Streamr (DATA) is an open-source project and decentralized platform that utilizes cryptography to ensure security, eliminating the need for trust. It functions as a P2P, real-time data infrastructure, providing a platform and tools for fostering a new data economy. The technology stack comprises a scalable real-time messaging network (pub/sub) distributed across computers worldwide, a marketplace for trading and selling data, and a suite of tools for managing real-time data. Streamr (DATA) was funded through a crowdfunding campaign in 2017. The core objective is to establish decentralized infrastructure and a data economy; the developers articulate the mission as “Unstoppable Data for Unstoppable Apps.” Streamr tokenizes the value of real-time information, making it accessible on their marketplace and through data unions. It is designed for DApps, IoT devices, and more, positioning itself as a critical protocol for Web 3.0. The functions of the Streamr DATA coin involve creating a user-friendly and prosperous information market based on a data exchange network that is straightforward and comprehensible for users. The decentralized pub/sub network operates through nodes worldwide, which earn DATA tokens in return for the bandwidth and validation services they provide. The competitive edge of Streamr lies in its off-chain network architecture, distinguishing itself from similar services like IOTA. This design reduces the risk of scalability and bandwidth challenges. The Streamr team focuses on developing network optimization technologies rather than creating a specific blockchain. Should Streamr encounter limitations with Ethereum, developers have the flexibility to migrate the platform to another blockchain.

Streamr Network AG, the legal entity driving the protocol's implementation, was established in 2017 and is headquartered in Switzerland. The Streamr open source team is composed of proficient programmers, financial experts, and software developers who operate across diverse time zones. Henri Pihkala, the founder and CEO of Streamr, holds a Master of Science in Computer Science from the Helsinki University of Technology. He brings experience in software development for real-time data processing, along with a decade of freelance IT consulting. Pihkala has served as a lead software engineer at RIQ Yhtiöt Oy and Hedgehog Oy, and as the founder and CTO of Unifina and Data in Chains. Risto Karjalainen, the founder and COO of Streamr, possesses a Ph.D. in decision sciences from The Wharton School of the University of Pennsylvania. Before joining Streamr, he worked as a quantitative analyst at Buchanan Partners Limited, an analyst at JP Morgan and Wadhwani Capital Limited, and an investment portfolio manager at Merrill Lynch and Estlander & Partners. He is deeply interested in real-time data and decentralized computing. Nikke Nylund, co-founder and director of business development, is a seasoned serial entrepreneur who has played a pivotal role in founding and expanding companies like Quartal Flife (acquired by Investis Ltd), Quartal Financial Solutions (acquired by KMU Capital AG), and Quartal Content Management (acquired by Satama Plc). Michael Malka leads Streamr Labs and has a background in computer science from the University of Helsinki. With over 20 years of software industry experience, he has progressed from developer to CEO. Malka has previously held development roles at Bitwise Oy, RTSe, and Quartal, and has served as CTO and later CEO at Sujuva.

Streamr (DATA) is a project dedicated to facilitating seamless data exchange and enabling the monetization of data. It operates as a peer-to-peer (P2P) network for real-time data running on Ethereum, which leverages smart contracts to streamline the exchange process. The network's core element is broker nodes, functioning in the following manner: data is received from providers, also known as publishers, and then transmitted to consumers. This operates on a publish/subscribe model, which the network adopts. Sponsors, who may also be publishers, pay DATA tokens into a smart contract referred to as a Bounty, ensuring the stream's operation. The data stream's security is maintained by broker nodes through mining Bounties and is relayed to subscribers via either publisher or broker nodes, with data streams being segmented. Several technologies developed to enhance Streamr are collectively known as the Streamr Stack, a hierarchically organized complex. This stack facilitates continuous data transmission within the Streamr network and is composed of five components: smart contracts (which optimize interactions among participants in the network's information market), the Streamr editor (a collection of programming tools designed specifically for the project), the Streamr engine (responsible for analyzing, processing, refining data, and monitoring network events), the data market (a hub for data streams and a platform for data transmission and reception), and the Streamr network (utilized for data transfer).

Streamr DATA is an ERC-20 token on the Ethereum blockchain, utilized for the node reward mechanism and bidding processes. Additionally, DATA tokens serve as a measure of reputation—nodes with a greater number of tokens hold more influence within the community. If a node begins to operate with errors, it is simply excluded, and traffic is not allocated for its curation. This token functions as a utility token within the Streamr P2P network, where DATA is used to compensate for infrastructure involved in data delivery. DATA can also serve as a payment method for data content on the Streamr marketplace, making it an essential component for the proper functioning of the entire platform. Following the completion of crowdfunding in 2017, a fixed supply of tokens was established. As of July 2021, the total supply is approximately 1,000,000,000 $DATA. The token allocation is structured as follows: 65% to crowdfunding participants; 15% to the founding team; 15% to the treasury; 3% to partners and consultants of the project; and 2% distributed among the Streamr community.

Smart contracts ensure the integrity of Streamr by overseeing every step of the data transfer process within the Streamr network. They manage the correct storage of information and maintain the history of events within each stream. Additionally, smart contracts facilitate the distribution of workload among brokers and license data for the sale and purchase of information. The development team has prioritized data security, transforming information into a product to ensure safety and reliability, preventing unauthorized third-party access. This is achieved through encryption, with the owner retaining the key. The platform supports integration with a wide range of encryption methods, allowing the owner to select their preferred option. Access to the data is determined solely by the owner, with smart contracts regulating the relationship between the owner and the consumer. This setup ensures a smooth and transparent process for buying and selling data. The Streamr DATA token is hosted on Ethereum due to its established reliability and efficiency. All transaction data is recorded on the blockchain, ensuring user identification and data protection.

Streamr (DATA) is currently available for trading on over 40 different exchange platforms. Several major exchanges that support DATAcoin include Binance, Uniswap (V2), Gate.io, Bitfinex, WazirX, Bancor Network, CoinDCX, Pionex, BKEX, LATOKEN, Omgfin, Hotbit, Mercatox, HitBTC, Folgory, Coinone, Hotcoin Global, NiceHash, Bitsonic, DragonEX, and BiONE.
