Blockchain is, like all systems in the world, far from foolproof and perfect to answer all existent problems in the world today. However, in terms of bridging gaps in terms of data sharing and production, payment processes, high intermediary fees, hidden transaction fees etc., I believe that blockchain has quite effectively provided great solutions. For example, some crypto/blockchain projects delve into securing international payments for products and services without having to deal with processing fees or long waiting times, or even rewarding and incentivising content creators to create and share quality content to earn tokens, or making trading more accessible and convenient for first-time crypto traders etc, and even ensuring that private/individual data is more secure and minimising the chances of data manipulation, which is very often heard about, considering all the news about data leaks from major companies recently. If there is a current problem in a traditional system e.g. payment processes and transactions, blockchain is currently the best solution to deal with it. What do you think about, for example, integrating blockchain as a solution in online shopping and e-commerce?

I came across a project recently on Medium called BlockCart - It looks like they are helping online shopping customers to regain control over the data they enter into shopping carts when they checkout, and also incentivising them for sharing their data with businesses that may use such data for marketing campaigns and also to better provide customer service to these consumers. Imagine not having to worry about the security of your credit card details when you make purchases! Apparently, they are working on a global shopping cart across multiple e-commerce websites so customers like you and I don't have to open multiple carts and checkout multiple times. And if businesses have access to the data these customers willingly share, they'll also be able to better recommend products and promotions to consumers - blockchain sure is an exemplary solution in this case!
