For example, a dormitory ABCD four people, usually more public expenditure, let the head of the dormitory accounts, and later discovered that the head of the dormitory quietly changed the books in order to bribe some money money.

A recorded an expense, there is also 88 yuan; B expenses 10 yuan, his account book is 88 yuan at the start and 78 yuan at the end, and C in the record at the start is 88 yuan.

C begins with $78 at the start of the entry. Before and after each sale, the "chain" is connected.

Let us now explain in academic terms.

Definition of blockchain: A blockchain is a shared, tamper-evident ledger that is used in a business network to facilitate transaction details and asset tracking steps. Property can be tangible (for example, a house, a car, cash, or land) or intangible (e.g., patent rights, patents, copyrights, brands). Almost any valuable item can be tracked and traded on a blockchain network, lowering risk and cost in all areas.

Blockchain is significant because business operations rely on information. The more quickly and accurately information is received, the more beneficial it is to business operations. Blockchain is the best option for delivering this data because it provides real-time, shared, and fully transparent information that is stored in a tamper-proof ledger and can only be accessed by authorized network members. Orders, payments, gtx 1080 ethereum hashrateaccount numbers, production, and other data can be tracked using blockchain networks. Because members share a single, reliable view, you have end-to-end access to all details of purchases and sales, giving you more confidence and opportunity while increasing efficiency.
