Are tightening regulations one of the reasons why decentralized marketplaces aren't taking off? Considering what happened to Silk Road in the past (although not truly-decentralized), it's likely such projects will remain a "niche" forever. Too bad because this had the potential to radically change e-commerce for the better.
Thoughts?
I don't think we are ready and the technology far enough for such market to have success. The current centralized marketplace provides much more benefits, discounts and safe place to trade and return. An open and fee marketplace would be overwhelmed by fake products, sellers and reviews. There would be no safe way of exchanging or returning products. The centralized market do make it easy for the suppliers and customers while decentralized market may mean suppliers need to be tech friendly to get listed. A good supplier would rather focus on decreasing cost of production and maintaining the quality rather than worrying about being listed.
