Hey, Nashons, thanks for the proposal!

Can you expand a little more on the journey of the data? Where it comes from, how it enters a Cartesi machine, how its processed (can be an example) and how the user will be rewarded?

Also, whats the plan for the data being kept anonymous until the owner decides to reveal it?


Hi Pedro,
Thank for the questions, below is a detailed breakdown for data journey in our platform

Journey of the Data

Origin and Collection

  • Where It Comes From: Data originates from the users themselves. This could be any form of digital information that a user generates or interacts with online, such as browsing history, online shopping behavior, social media activity, and personal health data.
  • Entry into the System: Users voluntarily opt into the MyData platform and submit their data. This could be through various interfaces or apps designed to interact with the MyData ecosystem. Upon submission, the data is encrypted to ensure privacy and security before it’s stored on the blockchain.

Processing through Cartesi

  • Entering a Cartesi Machine: Once data is submitted, it enters a Cartesi Machine—a virtual machine capable of executing complex computations off-chain. This is where the Cartesi Rollups technology plays a crucial role.
  • Processing Example: Consider a user submits data about their online shopping habits. The Cartesi Machine can process this data to generate insights about shopping preferences, trends, and potential rewards without revealing the identity of the user. All processing is done off-chain, ensuring scalability and efficiency, while the final outcomes or proofs are recorded on the blockchain, maintaining the integrity and security of the data.

Rewarding the User

  • ME Tokens: After the data is processed, users are rewarded with ME tokens. The amount of tokens awarded can depend on various factors, such as the volume of data shared, its perceived value, or the demand by third parties for that type of data.
  • Mechanism of Reward: Smart contracts on the blockchain govern the distribution of ME tokens. These contracts automatically execute the reward distribution based on predefined criteria, ensuring a fair and transparent reward system for users contributing their data.

Maintaining Anonymity

  • Encryption and Anonymization: Upon entry, all user data is encrypted to protect privacy. The MyData platform employs advanced encryption techniques to ensure that data remains anonymous and secure.
  • Control Over Data: The platform gives users complete control over their data, including whether or not to reveal it. Users can decide to keep their data anonymous or disclose it for additional benefits, such as higher rewards or personalized services. This is facilitated through the user interface, where users can manage permissions and control the visibility of their data.
  • Decentralized Storage: Utilizing decentralized data storage solutions like IPFS enhances anonymity by scattering encrypted data across multiple nodes. This minimizes the risk of data being linked back to the user unless they choose to reveal their identity.

Plan for Anonymity

The MyData project implements a robust framework to ensure data remains anonymous until the owner decides otherwise. This includes:

  • Using secure, encrypted channels for data submission.
  • Processing data in a way that does not require decryption to derive value, thus maintaining anonymity.
  • Giving users the power to selectively disclose information based on their comfort and the rewards they wish to receive.

In summary, the MyData project carefully handles user data from the moment it’s collected, through processing with Cartesi technology, to rewarding users with ME tokens, all while prioritizing user control and anonymity. The platform’s design reflects a strong commitment to data privacy, security, and user empowerment in the digital age.
