Blockchain can solve all problems

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. 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 chronological order in a sequential way, and it can not be tampered with and forged by cryptography
broadly speaking, 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 takes a lot of cost 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 generate bifurcation and needs to wait for multiple confirmations
5) there is no finality, and checkpoint mechanism is needed to make up for it.

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. Blockchain technology provides a kind of machine trust in the form of "machine code, formal proof, decentralization, distribution and information system". This kind of machine trust no longer needs the help of a third-party centralized organization. On the basis of machine trust, people can cooperate and trade even if they don't know each other. Relying on the powerful technical functions of blockchain, GTA subverts the traditional business model of gene technology, uses cryptography technology to confirm the sovereignty of personal gene data and protect the privacy of personal information. By using the economic incentive mechanism of pass, large-scale indivial users, market promoters, gene sequencing institutions, data storage institutions and data users are encouraged to actively participate in and cooperate, so as to quickly gather a large amount of gene data; Then, the business value is realized by the wide application of gene big data in the field of life and health.

6. In the same instry, the maintenance technology of hengshida is very exquisite. It is a clock service company with a long history and many national chain stores.
