1. There are a lot of
blockchains in China, although compared with the number of enterprises in other instries, they are very few. For example, Yingtang Zhongchuang has a good reputation at present, mainly for the underlying technical services and instry solutions of blockchain. That is to say, an underlying blockchain is built, and an adaptation layer is built on it, so that enterprises can quickly establish commercial applications.
2. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
if such technology wants to be put into application, the biggest problem is the "Impossible Triangle problem"
that is, scalability, decentralization and security cannot be achieved at the same time, and only two of them can be achieved
most of the existing public chain projects in the market are difficult to put into use on a large scale

3. I don't think it's expensive to build a blockchain system. Last time I cooperated with Shengshi Huacai company, their company's fees are reasonable and they are very conscientious in the blockchain system instry.
4. You can understand blockchain as technology. Cryptocurrency is based on blockchain technology. The technology itself is reliable and can also be applied in other instries. But after the fire of cryptocurrency, a lot of people came in. If you want to invest in it, you have to recognize which projects are real and which are fraulent. Novices suggest to know more about the blockchain instry. Besides, there are risks in investment. Whether you lose money depends on you. Cryptography focuses on blockchain information
5. Yes, blockchain is a new distributed infrastructure and computing method that 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, Self development costs are high, you can find related service providers, such as: Renren chain

7. This is fake. At first, I tell you that if you can brush 500 diamonds, you can withdraw 150 yuan. Then when you withdraw money, you say that you need to buy a big gift bag first, 2000 diamonds. The big gift bag is full of useless garbage. Then coax you to recharge to become what platinum member, in short, you can't get the money.
8. In the two sessions of this year, many provinces have incorporated the blockchain into the local "14th five year plan". It can be seen that the role of the blockchain is still very big. It is understood that at present, blockchain has been applied in many instries, such as government affairs, finance, supply chain, energy, chemical instry, agriculture, medicine, automobile, intellectual property and so on. It can be said that it is one of the core technology engines of new infrastructure
let's talk about the most understandable one. Isn't garbage sorting advocated now? In order to better promote the implementation of waste classification policy and effectively enhance the well-being of residents, Hangzhou Qulian Technology Co., Ltd. and Xi'an Sikes Internet of things Co., Ltd. jointly developed the first "Qulian intelligent waste classification system" based on "blockchain + aiot" technology in China. This system has been implemented in many communities and instrial parks in Hangzhou, such as "new lake Shangri La", "new lake film" and "cloud fox science and Technology Park", and has been widely praised.
9. In the field of Internet and games, blockchain is now a hot topic. Some people may even say that blockchain technology is the fifth disruptive innovation of computing paradigm after mainframe, personal computer, Internet and mobile Internet. It is difficult for us to determine what the future of blockchain will be like, but I firmly believe that the application of blockchain will be the development trend in the future.
10. Yes, they are
