Blockchain is a basic technology

If you are familiar with cryptocurrency, then you might be familiar with blockchain. Blockchain is a basic technology that ensures transactions are accurate, transparent and unchanged. Why is this technology important? When you work in a large number of individual stakeholders, there is always a fundamental existence of inconsistency. Even if you really trust other people, human error cannot be avoided.
The main difference between the blockchain and the database is centralization. While all records are secured on a centralized database, each participant on the blockchain has a secure copy of all records and all changes so that each user can see the origin of the data. Miracles occur when there is inconsistency - because each participant keeps a copy of the record, blockchain technology will immediately identify and correct unreliable information.
