As a game-changer,the emergence of blockchain technology is profoundly shaping the business,organization,economy,and society around the world.The blockchain is an open,distributed ledger that records transactions between two parties efficiently and in a verifiable and permanent way.It exhibits a chain structure composed of increasing blocks.The transaction data per unit time is encrypted into the block for that time period and used to generate a cryptographic hash of the next block.Underlying the novel technology,there are several distinguished features including distributed database,peer-to-peer transmission,transparency with pseudonymity,irreversibility of records,and computational logic.With blockchain,a new world could be imaged in which all form of transactions are embedded in digital code and protected from deletion,tampering and revision.The trust could be perfectly established by using the“algorithmic proof mechanism”in an asymmetric,uncertain,and insecure environment.
