Exposition: we've all heard of google, facebook and other tech giants collecting and selling end user data. There have been many eras in human history. Bronze, iron and industrial ages. Some refer to the current era as an information age. An era where information and data can be as valuable and coveted as bronze, industrialization or gold in previous eras. Retailers and big business utilize collected data to build better businesses and gain advantages over business rivals and consumers.
You are very right, but it remain one you have not mentioned, the information collected can be leaked to hackers, having valuable information to steal money from banks, stealing bitcoin and other cryptocurrencies from wallets. These data collection of a thing is turning the world towards stealing and privacy depriving.
Question: could there be a market for crypto currencies which focus on client side data mining, which work to the benefit and advantage of consumers. A market which might be undervalued and neglected atm.
I do not think this question is clear, but did you mean is there a way this data can be accessed using decentralized means?
Implementation: a working model of this could be defined by a blockchain and social media platform built around sharing and validating financial data in the form of purchases, investments and transactions inside of a public ledger. Sharing of client side information could help consumers to find the best investments, sales and deals. With the best information sharers being rewarded with crypto.
Have you heard about internet 3.0 before, this will be the next internet age the world will move towards and into, the internet will be robust and decentralized in a way mining will be used, people can use their computer for it and earn good, we will at the time not focus on centralized platforms like the current social media. At the time, information will not be managed in a centralized way but completely decentralized.
Marketing pitch: imagine if you could see every financial transaction and investment move made by Warren Buffett. Imagine if all of that data were shared and verified by a blockchain on a volunteer basis. In theory it could help consumers to learn better spending and saving habits. Perhaps manage their finances more like the pros. Could it help consumers to coordinate and cooperate to find better business deals and spending habits. Which could nullify advantages big tech and big business have with data mining schemes.
If internet 3.0 is allowed to be implemented, people will prefer to move towards privacy with time, or if they prefer to, you will see the powerful centralized bodies like Facebook and the likes reducing in usefulness, thereby nullifying the advantages of the big companies.
