❶ What is blockchain

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Simply put, blockchain is a decentralized distributed ledger database.

The meaning of data storage:

Data storage is a temporary file generated during the processing of data flow Or the information you need to find during processing. Commonly used storage media are disks and tapes. How storage is organized varies depending on the storage medium. Data on the tape is only accessed in sequential file mode; on the disk, it can be accessed sequentially or directly according to the usage requirements.

The data storage method is closely related to the organization of data files. The key is to establish the corresponding relationship between the logical and physical order of the records and determine the storage address to improve the data access speed. Among the various connection methods between servers and storage, DAS was once considered an inefficient structure and inconvenient for data protection.

Direct-attached storage cannot be shared, so it often happens that a certain server has insufficient storage space, while other servers have a large amount of idle storage space that cannot be used.
