"Two years of dabbling and experimentation and it’s mostly just been changing itself (so as to become even barely usable in capital markets)."

If it is moving from a distributed model to a shared model it is moving away from blocks. If it is moving from a distributed to a centralised model is its integrity compromised?

The more it moves these ways the less disruptive it comes and the more you will have to question its widespread use rather than niche use cases. 

In which case the question evolves into "Will it have been worth it economically?"
