Blockchain is really a basis of an ongoing digital revolution. This technology is a decentralized chain of blocks that record the information about data transfers. Blocks store encrypted information about transactions, deals and any other forms of data transfers. The chain does not have a common server — all blocks are located on each user’s device. Blockchain actually works similar to torrent. If you want to download the latest season of your favourite TV series, you connect directly to other users who have these files on their device. Each user of the blockchain network maintains its entire operation.
