What impact does the blessing of blockchain have on the security field?

In recent years, the concept of blockchain has been very hot. As many companies have touched the chain and deployed the blockchain industry, the blockchain has developed rapidly.
The essence of blockchain is a distributed ledger technology. Through a series of high-tech combinations such as distributed data storage, consensus algorithm, encryption algorithm, and point-to-point transmission network, it has the characteristics of distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Its core feature is: decentralization.
In a narrow sense, a blockchain is a chained data structure that combines data blocks in a sequential manner in a chronological order, and is a distributed ledger that cannot be tampered with and is guaranteed by cryptography. This This kind of distributed ledger can be completed by multiple nodes in different places, and each node records a complete account to ensure the legality of participating in monitoring transactions, and at the same time can jointly testify for it.
Broadly speaking, blockchain technology uses blockchain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses automated scripts. A new distributed infrastructure and calculation method for programming and operating data by smart contracts composed of codes.
So, what impact does the blessing of blockchain have on the security field?
Blockchain solves smart home network security
The intelligence, convenience, and efficiency brought by smart homes are the life we ​​look forward to and one of the future development trends. However, in the development process, we will inevitably encounter various difficulties that lie in front of us. Network security is one of them. Undoubtedly, Blockchain technology can solve the problem by generating, updating, and protecting data transmission and access security through a consensus algorithm between nodes.
Blockchain helps build an intelligent transportation system
Through blockchain technology, the intelligent transportation system can better improve road safety, ease and dredge traffic congestion, reduce energy consumption, reduce environmental pollution, and even improve the energy efficiency of the transportation system, strengthen the integration of traffic information, and better Cooperate with traffic management and monitoring.
Blockchain helps the construction of smart cities
The development of smart cities involves all aspects of the city and development. It requires the use of information and communication technologies such as information perception, automatic control, network transmission, and intelligent processing. It requires the development of various emerging technologies. Blockchain is undoubtedly one of the emerging technologies. For the application of blockchain, provide more secure, transparent and efficient solutions.
Blockchain breaks information silos
Data silos and information leakage* are important obstacles to the development of the security industry. The emergence of the blockchain is a good way to resume its navigation, integrating and transmitting multi-dimensional data, plus the decentralization of the blockchain, the data cannot be tampered with, The characteristics of permanent traceability, etc., can make the security data information play a greater role in a short time through the distributed accounting of the whole network, the win-win of the free public and the data monopoly.
