Rocket speed bitcoin and blockchain

Satoshi Nakamoto, who designed and developed the blockchain system and the first cryptocurrency bitcoin for it, is now seen by some of the world's leading technologists as the banking technology of the future and some banks in some influential countries are already investing billions of dollars behind it. The word 'who' is probably not correct here, it is assumed that Satoshi Nakamoto is the codename of a group of hackers whose real identities are still unknown.
A blockchain is the process of storing data by encrypting the encrypted information of all the financial or asset transactions that are taking place around the world in a fairly specific period of time. In this system, a distributed and decentralized laser is completely immutable with that block. It is actually a little difficult to understand in one sentence.
