Blockchain is a decentralized, distributed and public digital ledger that is used to record transactions across many computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network. Blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography (is the practice and study of techniques for secure communication in the presence of third parties called adversaries, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages). Blockchain was invented by Satoshi Nakamoto in 2008 to serve as the public transaction ledger (computer file for recording and totaling economic transactions measured in terms of a monetary unit of account by account type, with debits and credits in separate columns and a beginning monetary balance and ending monetary balance for each account) of the crypt...
