Despite the tremendous amounts spent to experiment with blockchain, few proof of concepts have been turned into pilots and even fewer into industrialized solutions. These many failures have left some people skeptical and assuming that the technology is not suitable for broad market applicability, as it only answers specific needs.
Most critics deplore the use of blockchain solely for marketing purposes, increasing the value of a brand by showing shareholders and customers the firm's ability to innovate. Misjudged expenses, difficulty-to-estimate profitability, and the impeding of stable revenue streams are also arguments pointed out by detractors, as well as the complications in developing scaled-up solutions.
Lots of technical challenges such as scalability and user-friendliness still have to be overcome as the technology gains popularity...
