区块链的实际数据存储是什么,区块链的实际数据存储结构

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.

❷ Blockchain is a way of storing data in memory, right?

Yes, blockchain is a distributed database technology, and data is stored in blocks. The form is stored on multiple nodes in the network, and encryption technology is used to ensure the security and integrity of the data.

❸ In what form is the data in the blockchain stored?

Blockchain is a distributed data storage, but the specific storage forms of different chains are different. Distribution The traditional storage technology does not store complete data in each computer, but separates the data and stores it in different computers. It's like storing 100 eggs, not in the same basket, but in different places, the total sum

❹ How is the data storage in the blockchain completed? The super server is trusted Third party

Hello, how is the super server trusted third party used to store data in the blockchain? The main role of blockchain is to act as a trusted third party, such as building transaction centers and data centers based on blockchain. The existing centralized method of establishing a set of public databases or establishing connections between multiple enterprise databases presents shortcomings such as high cost, low efficiency, and low security. It is usually necessary to find a credible social organization, an authoritative government department, or a recognized third-party industry leader to establish a centralized database and complete data storage, exchange and sharing through interactive services. In this scenario, each enterprise also has its own associated database system. The consistency and synchronization between different databases need to be repeatedly confirmed and verified with a third party that owns the shared database, or even manually verified, resulting in the generation of shared data. The reuse process is complex and inefficient. Additionally, since allWhen data is placed in a so-called authoritative third party, there is a natural risk of external attacks and internal employees stealing data. Once this authoritative central server is paralyzed, all external businesses connected to it will be interrupted. This is actually a potential challenge currently faced by Internet service providers, especially giants, and it is also a time bomb. The core capability of blockchain is to provide a consistent set of accounts, using blockchain technology to replace the role of this third-party Internet service giant, allowing multiple companies to use the same accounting system and record the same ledger. In view of the blockchain database The consistency and history cannot be tampered with, which can simplify and transform business processes, protect data integrity, and improve business operation quality and management efficiency. And when a certain node is paralyzed, the entire business will not be interrupted. Please refer to it!

❺ What are the practical applications of blockchain technology

1. Financial field

Blockchain is used in international exchange, letters of credit, stock rights registration and Financial fields such as stock exchanges have potentially huge application value.

2. Internet of Things and Logistics Fields

Blockchain can also be naturally combined in the Internet of Things and logistics fields.

Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved.

3. Public service fields

Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields, but the centralization of these fields Characteristics also bring some problems, which can be transformed using blockchain.

4. Digital copyright field

Through blockchain technology, works can be authenticated, prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership. sex.

5. Insurance field

In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs. Through the application of smart contracts, there is no need for the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the insurance policy can automatically settle claims.

6. Public Welfare Field

The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for social welfare scenarios.

❻ Where is the data in the blockchain stored?

The data in the blockchain all exists in the terminal or in the server. Because we are talking about blockchain, its user terminal can also be a server, and the server can also be a user terminal, so it is all stored on these devices.
