So this really started from a long time ago. Really nice to see that someone took out their time to record all these and put them together, so that everyone can be able to see where and how it started. They have been on this since the 70s and it continued till the last decade and we have got bitcoin from Satoshi who we are yet to know who he is. A lot of people are still confuse at what us the purpose of all this and what bitcoin us really meant for, sometime in the future we will get to know, as for now, it is for a peer-to-peer transaction.
