1. 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.
2. The most important thing of blockchain is to solve the problem of intermediary credit. In the past, it was difficult for two people who didn't know and trust each other to reach cooperation, and they had to rely on a third party. For example, in the past, there must be a bank or an institution such as Alipay. However, through the blockchain technology, bitcoin is the first time for human beings to complete the transfer behavior that can be trusted by both parties without the participation of any intermediary. This is a major breakthrough in blockchain. Now there are many procts and applications based on blockchain technology. Lifechain is a medical and nursing enterprise based on blockchain technology. You can learn about it.
3. The relatively stable currencies in foreign exchange are US dollar and euro< Note:
1. Foreign exchange is the creditor's right that the monetary Administration (central bank, monetary administration, foreign exchange stabilization fund and the Ministry of Finance) can use in the event of balance of payments deficit in the form of bank deposits, treasury bonds of the Ministry of finance, long-term and short-term government securities, etc

4. Jinwowo thinks that if blockchain technology wants to be widely used in China, the first problems to be solved are as follows:
1 - blockchain is too large
2 - blockchain data confirmation time
3 - deal with the issue of transaction frequency
4 - the development of blockchain technology is restricted by the current system
5 - the integration cost of blockchain technology and existing systems is relatively high

5. 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.
6. Blockchain may affect all walks of life in the future, such as contracts, laws, exchanges and so on. Ruitai coin is a socialization attempt of blockchain digital asset.
7. In the blockchain database, each user node has a complete of the whole database, and when a user node wants to write data to the database, it needs to broadcast the data to the blockchain network, so that other user nodes can verify and audit the data. Data can only be written into the blockchain after the whole network has jointly verified and approved, and once the data is written into the blockchain, it cannot be modified or deleted at will.
