1.
Because the design of blockchain is a kind of protection measure, such as distributed computing system with high fault tolerance. Blockchain makes hybrid consistency possible. This makes blockchain suitable for recording events, titles, medical records and other activities that need to include data, identity management, transaction process management and provenance management. Blockchain has great potential for financial disintermediation and has great influence on guiding Global trade
extended data :
1. Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
2. Blockchain is an important concept of bitcoin, which is essentially a disintermediated database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
3. Blockchain - the original blockchain is a kind of decentralized database, which contains a list called blocks, with continuously growing and orderly records. Each block contains a time stamp and a link with the previous block. The block chain is designed so that the data can not be tampered with. Once recorded, the data in a block will be irreversible

2. IBM, Microsoft, Oracle, Accenture, Tencent, Alibaba, Jingdong, network, etc. have all done it. Many large banks, including Ping An Bank, have also launched their own blockchain solution platforms or solutions. However, it should be added that large companies do not mean strong technical strength, because blockchain is still in the hot stage of concept in the world. Unicorn blockchain companies are likely to emerge in the future, such as EOS in foreign countries and honeycomb chain of Fanrong technology in China. The efficiency of TPS and packing into blocks may be much higher than that of large companies.
3. Now there are many people doing his blockchain, and his loopholes make money. I think we can really make money, but her family should also choose through formal channels.
4. 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
blockchain technology is considered to be the next generation of disruptive core technology after steam engine, power and Internet. If the steam engine has released people's proctivity, the power has solved people's basic living needs, and the Internet has completely changed the way of information transmission, then the blockchain, as a machine for building trust, may completely change the way of value transmission of the whole human society
first, the essence of blockchain is a distributed public ledger
take a popular example to explain that Mr. w's family, including Mr. W, Mrs. W, Mr. w's grandfather and Mrs. w's grandmother, all record their expenses in their respective books. Because Mr. w's family doesn't trust each other. Mr. W is diligent in raising his wife every month, but Mrs. w may receive 1000 yuan, but she receives 100 yuan. Isn't that a big loss
how to solve this problem with blockchain
if Mr. w gives Mrs. w $1000 one day, he just shouts at the whole family that Mr. w gives Mrs. w $1000. Please write down "Mr. w gives Mrs. w $1000" on their respective account books
so everyone in Mr. w's family becomes a node, and every transaction of Mr. w's family is recorded by everyone (each node)
every night who washes the dishes (proof of workload) can settle the bill in the public ledger, and there is a reward for washing the dishes. A new transaction must be added to the universally recognized ledger of the previous day, and other people will also participate in verifying the transactions of the day
Second, it seems very simple, but blockchain may bring revolutionary changes to human society
1. Machine trust
machine trust is actually trust without trust. For the first time in human history, a large-scale cooperation network unprecedented on earth can be established at near zero cost, which is bound to be a great mass movement
2. Value transfer
the emergence of the Internet has made the means of information dissemination achieve a leap, and information has realized efficient flow, but the efficiency of Internet value transfer is still very slow. At present, e-money on the Internet is still the traditional paper money in essence, and transnational payment is still a big problem
the birth of blockchain is the beginning of human value transmission network. It will enable people to transfer value as conveniently and cheaply as information on the Internet, which can be expressed as capital, assets or other forms
3. Smart contract
smart contract can replace all paper contracts, and more importantly, blockchain can perfectly connect the physical world and virtual world. The perfect combination of blockchain, Internet of things and artificial intelligence makes the imagination more huge
the blockchain itself is actually a super platform. The commercial characteristics of building machine trust, value transfer and smart contract on the blockchain are: ① close to zero trust cost. ② The marginal cost of constructing and trading assets tends to zero
so Mark Anderson, a web browser pioneer, said: in 20 years' time, we will talk about blockchain as we talk about the Internet today.

5. Yes, there are some, but I don't know which one to do
6. Yes, but it's better to have your own arms. Where there is no gun, the security is relatively poor. Gold is a thing that can easily make people crazy. You can go to the website of amanbo to have a look. There is a lot of information. I wish you good luck and hope to adopt it. Thank you!!
7. Big companies will do their own instry open platform< Make complaints about br />

8. Blockchain is a technical solution to maintain a reliable database collectively through centralization and distrust in the past
generally speaking, blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems. You can think of the database as a big ledger. So it's very important who keeps this account book. At present, whose system will keep accounts, wechat's account book is Tencent's account book, and Taobao's account book is Ali's account book. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there is any data change in a certain period of time, everyone in the system can conct bookkeeping. The system will judge the person who has the fastest and best bookkeeping in this period, write the content of his records into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. This way, we call it blockchain technology
cryptocurrencies such as bitcoin, Puyin, Ethereum and dogcoin are just an application of blockchain.

9. It has nothing to do with designers, but it has a great relationship with everyone. The popularization of blockchain technology will change the existing mode of life, involving all aspects of the field.
10. When we talk about blockchain, we mean the blockchain technology, which is an architecture design method to realize the open, transparent and traceable data of procts. It can be regarded as a broad blockchain. With the graal growth of blockchain technology, it is more and more difficult to be ignored by the general public. The business community will pay more and more attention to blockchain technology. At present, many blockchain technology development enterprises, Renren chain is one of the more prominent blockchain system development platform. Blockchain technology can be fully used in value storage, transaction process and payment. Compared with traditional financial institutions or intermediaries, blockchain system can complete fund transfer at a lower cost and higher speed in domestic or cross-border transactions.
