The adoption of blockchain technology is a work in progress. There are details that have to be worked out; a fully secure and decentralized system needs to be built; scalability and performance must be optimized. Yet there is one major tension that must be resolved first: there needs to be a strong consensus mechanism.
You are hitting the main bottleneck of blockchain i.e. integrating scalabilty, security and decentralization in one place. So far there is always a tradeoff b/w these three features. Bringing all these at one single table will be like a revolution.
