Intro to Data Unions
An overview of the Data Union framework
🧱 Fundamentals
The Data Union Framework
The Data Union framework powers applications that incentivize people to participate in the crowdsourcing of valuable data. It enables people to earn with their data.
Smart contracts and decentralized networks are used to transfer tokens and data. It is the infrastructure that powers data unions.
The framework is a token distributer and a member manager.
Framework Infrastructure
for the distribution of data sales between members, the Data Union admin, and the Data Union DAO.
The smart contract handles:
data price/data sells
admin fee (royalties from sold data to the contract owner, i.e. Data Union admin)
distributing and withdrawing earnings
member management
ownership
Your Data Union Application/Device
This is your client application/device that provides the data. Ideally, it's an application with a continuous flow of data coming from the client. For example, a temperature measurement, browsing data, or user behavior.
Check out some existing data unions for more examples here.
Streamr Network (data transfer) OPTIONAL
a peer-to-peer network for the transfer of real-time data.
All the client data gets published to a data stream that flows through the Streamr network. We visualized the data stream with the black arrow in the illustration below.
The official documentation of Streamr can be found here.
Workflow of the Data Union framework infrastructure with Streamr
User joins a Data Union
User grants permission and consent to the data union to have their data monetized
Data is created and crowd-sourced through the Data Unions' application
Data flows through Streamr Network into the marketplace
Data is bundled as a product for sale on data marketplaces
Data is bought by a buyer
Revenue from data sales flows through the smart contracts via the EVM-chain of your choice and is split between the members, the data union admin and the DU DAO (1%).
The more active members/data providers in a Data Union the more valuable it becomes to potential data buyers/data subscribers.
A Data Union earns a percentage of the data sale for maintaining and growing the organization and its members. That percentage can be set anywhere from 0% to 100% (although it is usually around 30%). The Data Union DAO (DU DAO) receives a 1% protocol tax from data sales for providing the Framework and for growing the Data Union ecosystem.
