Hi! Currently blockchain technology is disrupting many traditional processes and systems in the world, presenting the possibility of removing intermediaries in areas such as the one you have raised - data. This means data production, data sharing, data dissemination and more. One sector that comes to mind is the retail/e-commerce industry where customers/shoppers like me enter my details (email, name, address, payment details etc.) every time I make a purchase. Or even social media accounts like FB, Instagram etc. especially as the system remembers your preferences e.g. what kind of videos/photos you like, how long you watch it for etc.

The problem with this is that I don't own my data - most people probably aren't conscious of the digital trail they leave behind when they surf the internet - and huge companies like FB are vulnerable to data breaches/hacking, where such personal data can be stolen and this has been proven true. Blockchain developments in this case is great for businesses and individuals like you and I to secure and actually own personal data - if via a smart contract the terms are set for me to share my data as a user, and businesses are required through the smart contract to pay me for the data I provide directly, this would possibly eliminate the need for data brokers/intermediaries that sometimes charge exorbitantly high fees on their data (and we don't even know if the owner of the data willingly allowed it to be shared/sold)

Last week I came across an interesting project that is intending to solve this problem of data ownership! What do you think about this?
