now a days we are hearing a lot that blockchain can change the way we use technology but in reality i could not explore anything till now which is based on this new age technology. I agree that I may be asking for it too early since few big companies have already started exploring blockchain. I am pretty sure that blockchain can change the way of payment and i am eagerly looking forward to see that change. Can you name out some companies which have started working in Blockchain? in your post you explained everything nicely.
