A Deep Dive Into Streamr

To learn more about this project, check out our deep dive of [Streamr](https://coinmarketcap.com/alexandria/article/a-deep-dive-into-streamr).

## What Is Streamr (DATA)?

[Streamr](https://coinmarketcap.com/currencies/streamr/) (DATA) is an open source project and decentralized platform that relies on cryptography instead of trust. It is a [P2P](https://coinmarketcap.com/alexandria/glossary/peer-to-peer-p2p), real-time data infrastructure that houses a platform and tools for a new data economy. The technology stack includes a scalable real-time messaging network (pub/sub) hosted on computers worldwide, a marketplace for trading/selling data and a set of tools for working with real-time data.

Streamr (DATA) was crowdfunded in 2017. The main idea is to create decentralized infrastructure and data economy; the mission was formulated by the developers as “Unstoppable Data for Unstoppable Apps.” Streamr tokenizes the value of real-time information and makes it available on their marketplace and data unions. This is built for [DApps](https://coinmarketcap.com/alexandria/glossary/decentralized-applications-dapps), [IoT](https://coinmarketcap.com/alexandria/glossary/internet-of-things) devices and more, and they believe this is a crucial protocol for [Web 3.0](https://coinmarketcap.com/alexandria/article/what-is-web-3-0). 

The tasks of Streamr DATA coin include creating a comfortable and prosperous information market, which is built on the basis of a data exchange network that is convenient and understandable for users. How it works: the decentralized pub/sub network is supported by nodes around the world, who earn DATA tokens in exchange for the bandwidth and validation they provide.

The competitive advantage lies in the fact that it is an off-chain network (for example, when compared to a similar [IOTA](https://coinmarketcap.com/alexandria/article/a-deep-dive-into-iota) service). Therefore, the risk that the project will face scalability and bandwidth issues is modest. The intention of the Streamr team is not to create some special blockchain, but to focus on the development of network optimization technologies. If Streamr lacks the capabilities of Ethereum, developers can always transfer the platform to another blockchain.


## Who Are the Founders of Streamr?

## What Makes Streamr (DATA) Unique?

Streamr (DATA) is a project focused on seamless data exchange and monetization of this data. It’s a peer-to-peer ([P2P](https://coinmarketcap.com/alexandria/glossary/peer-to-peer-p2p)) network for real-time data that runs on Ethereum, allowing smart contracts to be used to facilitate the exchange process.

Broker nodes are the key element of the network, which work as follows: data is received from providers (also called publishers) and transmitted to consumers – this is the publish/subscribe pattern that the network uses. Sponsors (which may be publishers) pay DATA tokens into a smart contract (called a Bounty) to secure the operation of the stream. The data stream is secured by broker nodes mining Bounties, and relayed to subscribers through publisher or broker nodes (data streams are segmented).

A number of technologies that have been developed to optimize Streamr are a hierarchically organized complex called the Streamr Stack. This complex supports uninterrupted data transmission in the Streamr network and consists of five blocks: smart contracts (responsible for optimizing relations between participants in the network's information market); streamr editor (a set of programming tools developed for the purpose of the project); streamr engine (responsible for analyzing, processing, refining data and monitoring network events); data market (a center for data streams and a platform where data is transmitted and received); streamr network (used to transfer data).

## How Many Streamr (DATA) Coins Are There in Circulation?

Streamr DATA is an [ERC-20](https://coinmarketcap.com/alexandria/glossary/erc-20) token on the [Ethereum](https://coinmarketcap.com/currencies/ethereum/) blockchain. The token is used for the node reward mechanism and bids. Moreover, DATA tokens are a measure of reputation – the more tokens a node owns, the more weight it has in the community. If a node suddenly starts working with errors, it is simply excluded and traffic is not allocated for curation.

The token is a functional utility token in the Streamr P2P network – DATA is used to pay for infrastructure involved in data delivery. DATA can also be used as a payment token for data content on the Streamr marketplace, so it is an indispensable detail for the entire platform to function properly.

Upon completion of the crowdfunding in 2017, a fixed supply of tokens was created. As of July 2021, there is a total supply of around 1,000,000,000 $DATA. The token allocation is as follows: 65% to crowdfunding participants; 15% to the founding team; 15% to the treasury; 3% to partners and consultants of the project; 2% distributed among the Streamr community.


## How Is the Streamr Network Secured?

[Smart contracts](https://coinmarketcap.com/alexandria/glossary/smart-contract) ensure the integrity of Streamr, as they supervise every step of the data transfer process on the Streamr network. Smart contracts control the proper storage of information and the maintenance of the history of events within the stream. Furthermore, smart contracts distribute the workload between brokers and license data (for the sale and purchase of information).

The developers took the data security issue seriously; they have turned information into a product to provide its safety and reliability, so that a third party cannot get access. This is done by making the data [encrypted](https://coinmarketcap.com/alexandria/glossary/encryption) and the [key](https://coinmarketcap.com/alexandria/glossary/private-key-secret-key) is held by the owner. As for the encryption method, any type can be chosen because the creators of the platform have provided the ability to integrate almost any option. Only the owner of the data decides who has access to information; the relationship between the owner and the consumer is regulated by smart contracts. This nuance guarantees a smooth and transparent process of selling (and buying) data.

Streamr DATA token is on Ethereum for a reason – this blockchain has already proven its reliability and efficiency. All payment data is recorded in the blockchain, which ensures user identification and data protection.

Civic is a blockchain-based identity management solution that gives individuals and businesses the tools they need to control and protect personal identity information.

The platform is designed to change the way we think about identity verification by giving users more control over their personal data, while allowing them to access a wide range of services without needing to fork over excessive amounts of personal information.

Civic's identity verification solution uses distributed ledger technology to authorize identity usage in real time, and is used to sparingly share information with Civic partners after authorization by the user.

Unlike some other identity management services, Civic users store all their sensitive data on their mobile device. Users are able to authorize the sharing of specific personal data by providing a biometric signature through the Civic app.

The Civic ecosystem is enabled by a unique utility token known as the Civic token (CVC), which is used for the settlement of identity-related transactions between Civic participants — such as between a customer and service provider.

Users can earn CVC tokens for completing a variety of tasks, such as signing up for a service through the platform or introducing new users, while validators can earn CVCs for validating documents for service providers.

Civic was launched in 2018, following a sell-out initial coin offering (ICO) the year prior.

Storj, pronounced as “storage,” is an open-source cloud storage platform. Basically, it uses a decentralized network of nodes to host user data. The platform also secures hosted data using advanced encryption.

In a white paper published in December,2014, Storj was first introduced to the world as a concept. It was to be a decentralized peer-to-peer encrypted cloud storage platform.

Two years later, an updated white paper was published. Here, a decentralized network  — connecting users who need cloud storage space with those who have hard drive space to sell — was described. The platform was launched in late 2018.

People with hard drive space and good internet connectivity can participate in the network. They become a unit in the network, called a node. Space providers are rewarded by Storj tokens.
