1. "blockchain" is an important concept in the new era. In essence, it is a centralized database, and also an underlying technology such as digital currency. According to our popular explanation, "blockchain" can be regarded as an account book. Every bill is every block, but this account book is centralized, and it can be said that no enterprise or team has jurisdiction over it“ "Blockchain" technology is a unique information technology, such as centralization, information can not be changed in series. Now this technology has been applied to a series of applications such as electronic invoice, payment code and so on
in today's life, many people use this pretext to cheat, such as direct selling, capital, technology, etc. There is no right or wrong in technology, but in people
with the progress of the times and society, the beginning of the application of any technology will be questioned positively and negatively. However, with the relative application and maturity of technology and the improvement of technology, the various applications around people will continue to improve. I believe that in the near future, these doubts will graally dissipate
the following is a summary of some blockchain scams around us
trap 1: block chain is the coin trap
trap two: virtual currency transactions, promise low investment, high return
trap three: centralization can solve all problems
trap four: block chain extension procts can be laid down with a mining machine to earn money
trap five: WeChat, Alipay trading transactions virtual currency

Because the blockchain technology is not mature at this stage, and the infrastructure is not perfect, many applications are limited, and the overall application is still in a very early stage
First of all, the main function of blockchain is to store information. Any information that needs to be saved can be written to or read from the blockchain, so it is a database. Secondly, anyone can set up a server and join the blockchain network to become a node. In the world of blockchain, there is no central node (decentralization). Every node is equal and keeps the whole database. You can write / read data to any node, because all nodes will be synchronized in the end to ensure the consistency of the blockchain3. Yes, it supports. There are many policies on record. You can see that there are also policies to encourage blockchain entrepreneurship. There are different preferential policies in different places

4. It mainly depends on the functions of the blockchain application app. For example, starting technology is to calculate the development cost of the blockchain according to its functions. If there are many functions and high complexity, the corresponding cost will be relatively high, and the function will be simple, and the price will be very low. Whether it's blockchain wallet, blockchain exchange, blockchain pet game or blockchain points mall, the price is estimated in this way. The main accounting of the development cost is the labor cost and hardware consumption cost, plus some marketing expenses, we can almost determine the price. In one case, the price of the app will be very low, that is, there is a ready-made source code that can meet the needs of customers, and you only need to modify and add some functions to use it.
5. The story of blockchain and Chinese pork starts from Wal Mart. The retail giant recently opened a new "food safety cooperation center" in Beijing and will work with IBM and Tsinghua University to trace China's pork supply chain using blockchain technology
Wal Mart is looking at the potential of blockchain and hopes to use blockchain technology to help it trace food. China has the world's largest pork market, and its pork imports rose 76% in February, according to the Wall Street Journal. Wal Mart intends to cooperate with pork suppliers in China first. If it succeeds in pork procts, it will expand to other procts
most of the previous applications of blockchain were in the field of financial services, and this application in food supply will be an eye-catching case. Wal Mart is very concerned about the traceability of food and thinks that the tracking and records of China's food supply chain are not perfect. Gopinath said that traceability is the key. From slaughterhouse carcasses to packaged finished procts, if bar codes are pasted on every step and all handover work is recorded, the traceability of procts will be greatly improved, and consumers certainly want their food to be safe
this and European crowdfunding, the crowdfunding platform, make the perfect combination of digital currency and real assets by using blockchain technology, and make users' investment more secure.

6. Blockchain is the underlying technology of bitcoin. You can think of blockchain as a distributed database for storing bitcoin transactions. In the whole network, each node will have a complete blockchain
blockchain technology has realized the key characteristics of tamper proof, decentralization, anonymity, security and reliability. Now more and more instries choose to use blockchain technology. For example, NASDAQ has adopted blockchain technology to realize LINQ, a private equity trading platform. It is more secure, and the transactions stored in the blockchain can not be tampered with, that is to say, once written, it is impossible to be modified. In the future, the application of blockchain will be very wide, and all aspects can be applied to blockchain technology. For example, in the future, schools can store the electronic version of Graation Certificate in the blockchain, which will not be tampered with. Employers can check the authenticity of students' graation certificate by querying the information in the blockchain.
