The blockchain technology is being actively adopted by finance, retail, insurance, and other industries as it helps to achieve well established workflows through simplifying record / identity management, transaction processing, goods provenance and traceability. By excluding an intermediary, the technology also allows for minimizing or eliminating the counter party risks, as well as reducing overhead costs, transaction time, and the related fees. Basically blockchain connects the world to crypto. A 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. This allows the participants to verify and audit transactions inexpensively.
