We all by now have passed the level I of blockchain learning defining it as a Distributed/Decentralized ledger to store transactions. We all know the technology part of it but the true revolution blockchain brings is by social engineering. In the blockchain network participants are not anonymous rather pseudonymous. Anyone in this world from any place can participate in the network only using his smart phone and internet. Anyone means nobody (google or goverment or anyone) can block any participant or service in and from the network respectively.
