> Somebody else could build a centralized trading platform, and if you use that, it will be cheaper for all parties. Oh absolutely, a centralized digital assets trading platform for general digital goods would be better in almost every (at least technical) way compared to a blockchain/decentralized platform. The challenge isn't technical, it's getting parties to trust you and your platform, and to use it. That's maybe the one (if not the only) upshot to using a blockchain; I don't necessarily have to trust the platform. That said, Visa and Mastercard basically have a duopoly on digital payments, so it's not unrealistic to think someone could do the same but with trading/tracking ownership of digital assets.
