They have control over an unprecedented amount of data in their data silos.&nbsp;&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p>Here is a scenario! What if everyone &#8211; individual or organization- can contribute their private data and get compensated to create a database that preserves the privacy of the data yet allows AI models to train on them? It would provide data scientists with the required organized and labeled data. Decentralized Machine Learning (DML) can assist in making this feat possible.&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p>DML involves training a machine learning model on data from a blockchain-based data marketplace. It is an infrastructure that addresses issues related to centralization in AI. These include data privacy, centralized model training, and expensive computation.&nbsp;&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p>Let&#8217;s see in detail how DML solves these problems. Decentralization can mainly affect ML&#8217;s three main building blocks: the data, the model, and the computing power.&nbsp;&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p>We recommend a smart contract-based data marketplace where individuals get incentives to provide data. This data is referred to but is not limited to the medical and financial sectors, where data security and privacy are of utmost importance. Interested researchers can use this data with permission to train their ML models. Some of these data marketplaces are Datum, Ocean-Protocol, and BigChainDB.&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p>Let&#8217;s discuss in brief how they work.&nbsp;&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Datum&nbsp;<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Datum Network provides a blockchain-based decentralized private data storage platform. Here the users can securely store their private data or the data extracted from edge devices like smartphones, IoT sensors etc. with which they interact. Here are some of its key features-&nbsp;&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Here the users can decide with whom to share the data.&nbsp;&nbsp;<\/li><li>The Data scientists and researchers can request the data from the owners.&nbsp;&nbsp;<\/li><li>Storing and monetizing data are powered by Datum&#8217;s native token, Data Access Token (DAT), based on the ERC-20 on Ethereum Mainnet.&nbsp;&nbsp;<\/li><li>The data is stored as a key-value pair, ensuring data integrity, availability, low latency, and data searching.&nbsp;<\/li><li>Data providers, data consumers, and storage nodes are the critical stakeholders of Datum and are suitably rewarded for their contributions.&nbsp;<\/li><\/ul>\n\n\n\n<ol class=\"wp-block-list\"><li>Data providers &#8211; They are rewarded for providing the data and giving permission to use it.

They introduced an exciting concept where data owners can tokenize their dataset into ERC721 data-NFTs and ERC20 data tokens. Anyone who owns the Data-NFT owns that data and can decide who uses it and how to generate revenues from it. The data tokens are a medium to transfer data ownership.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p>Along with this, they provide a compute-to-data algorithm that lets the data stay on-premise of the user, yet (by consent of data owners) allowing researchers or data scientists to run AI models or any other computing jobs on the data without ever sharing the data itself.&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p>Data owners can create a liquidity pool and launch an initial data offering (IDO) which allows data to be investable via ERC20 tokens.
