Blockchain system is a technology used by many businesses and commercial structures in recent years. Thanks to its many advantages and functionality, it is preferred more and more every day. Blockchain advantages can be listed as follows; More Confidence As a member of a members-only network with Blockchain, you can receive accurate and timely data. Also, your confidential blockchain records are only shared with network members you have specifically granted access to. This gives more confidence in the system. More Security Consensus on data accuracy from all network members is required. Since all verified transactions are permanently recorded, they cannot be changed again. No one, not even a system administrator, can delete a process. Therefore, security measures are at the highest level. More Efficiency Time-consuming record reconciliations are eliminated with a distributed ledger shared among members of a network. To speed up transactions, a set of rules called smart contracts can be stored on the blockchain and executed automatically. In this way, working efficiency and unnecessary workload are eliminated.
