The efficiency of blockchain

1. As a kind of decentralized database, blockchain has the characteristics of openness, distribution and irreversibility. As an electronic data storage platform, blockchain has the advantages of low cost, high efficiency and stability. At present, blockchain has been applied in many fields and has brought many changes to our life. Now many electronic contract platforms, such as Fada This kind of blockchain technology has been applied in the chain of evidence, and the blockchain technology has also been accepted by the court

2. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry
taking the tourism instry as an example, blockchain applications mainly focus on tourism travel, tourism community reviews, digital identity management, credit consumption management, tracking pilot's professional certificate and qualification, loyalty plan of hotels and airlines, reservation management and consumption points management. In addition, blockchain also has applications in finance, games, entertainment and other fields.

3. Blockchain has a high degree of technical security and broad technology prospects. It is still in continuous development, improving enterprise efficiency and recing operating costs, and will graally be promoted and applied in other fields and instries
Renren chain is an enterprise level platform service based on mainstream blockchain technology, which can help you quickly build a more secure and stable blockchain environment, rece challenges in blockchain deployment, operation and maintenance, and development, and enable you to focus more on core business innovation, so as to realize fast business on the chain
in the current enterprise management mode, no matter customer relationship management, project management, procurement management, human resource management, there are data security and reliability problems to some extent. For example, sometimes transaction data under the market mechanism is untrue / fake / deleted and changed, and some problems such as making ill considered decisions e to data resource blocking occur, In the long run, it will cause harmful business impact on enterprises. Moreover, some enterprise systems are lack of real-time tracking in the process of the project, which is prone to data disorder and lag, resulting in the inability to timely monitor the project and track the responsibility, low management efficiency and so on, which can be avoided in the early selection of enterprises!

4. I choose Chinese currency! Low operation delay, idle can also save money mining EOS, very suitable.

5. In fact, the level of Kung Fu has a physical change, but I don't know. Your martial arts is called scientific martial arts.

6. In one sentence, it is decentralization. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system. In a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing method, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data. Advantages: 1) the algorithm is simple and easy to implement; 2) There is no need to exchange additional information between nodes to reach a consensus; 3) It costs a lot to destroy the system. Disadvantages: 1) waste of energy; 2) It is difficult to shorten the block confirmation time; 3) The new blockchain must find a different hash algorithm, otherwise it will face bitcoin attack; 4) It is easy to proce bifurcation and needs to wait for multiple confirmations; 5) There is never finality, and checkpoint mechanism is needed to make up for it.

7. Most business development needs to establish a certain trust foundation, especially in the cross agent scenario. Blockchain can provide very effective help for application scenarios with difficult trust establishment and high trust maintenance cost.
