1. There are relatively large 360 and thunderbolt, but I really don't know what is the regional chain
2. It's not the same thing
big data refers to the technical difficulties caused by too much data, mainly 4V, large amount of data, fast data generation, diverse data formats and low data value
there are many corresponding technical problems to be solved
blockchain is a technical term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance".

3. ① What is digital assets
MBA think tank defines "digital assets": digital assets refer to non monetary assets owned or controlled by enterprises, existing in the form of electronic data, held in daily activities for sale or in the process of proction
in our life, direct consumption in Alipay is a common way to use digital assets, that is, electronic payment system. Besides, we often use network assets, Internet stocks, online reading or audio and video broadcasting. We are using digital assets. For enterprises, online coupons or points are the use of digital assets, and some companies also distribute equity in the form of digital assets
2. Why digitalize assets<
as for the allocation of private digital assets, Xiao Feng, vice chairman of Wanxiang holdings and chairman of Tonglian data, said at a financial technology investment summit that in order to get more than expected returns, it means that we must adopt a different way of asset allocation from others. In the future, the most obvious opportunity for alternative asset allocation may be digital assets. In the next 10 years, This new asset class cannot be ignored. For the society, asset digitization is a major trend
for enterprises, asset digitization is the best solution to rece costs and increase efficiency. If the privacy file is encrypted and saved by technical means, the security will be far greater than that in the entity. And digital assets are also convenient for enterprises to manage. When the era of big asset management comes, asset management needs to face thousands of asset types, involving a large number of calculations, which can not be completed by manpower alone
③ why use blockchain technology to digitize assets
1. Distrust. Through the distributed system of the blockchain, the trust between people is transferred to the trust in the machine, and the machine will not cheat people - it has no feelings and only operates in its own way. This greatly reces the number of central links generated by trust. In some instries, intermediaries can even be removed. Supply and demand trust is entirely based on this magical machine
2. Decentralization. At present, if you want to transfer the equity you hold, you have to go through a lot of proceres and find different departments to do it well. It's a waste of time and money. If blockchain technology is combined with electronic contract, this problem can be solved. Shareholders can trade their shares just like buying and selling T + 0 shares, and they are also protected by law. What about cross chain technology Cross chain: for example, you directly use your shares to buy other people's digital rights, recing the steps of exchanging legal currency.) How convenient that would be
3. Highly transparent. Now the business's biggest fear is information opacity. The application of blockchain technology can solve this problem. As long as the public digital assets are set up, everyone can view them. If necessary, the number of assets held by the owner can even be displayed, and some shady transactions can be avoided
4. Anonymization. We often do "streaking" on the Internet carelessly. Our information is sold at a price in some bad companies. We check all the system records of a person for several hundred yuan. We can receive some sales calls from time to time in our daily life, and most of the fraud calls are successful only after we know your information. In the blockchain, we only display one address for transactions, which can effectively protect our own information and rece the possibility of information being sold publicly
in terms of digital assets, blockchain technology is a "customized" technology with its security, confidentiality, openness and transparency.

4. To be honest, there's no way. Ethereum will exceed 2T, even if only some blocks are synchronized, it will take 20g. And now it's blocked and dissatisfied, and it's bound to collapse
5. Xu Mingxing, as a veteran of the blockchain instry, has a very forward-looking vision. He has experienced the whole development process of the blockchain instry. Xu Mingxing realizes that many procts of domestic cutting-edge instries still rely on the introction of foreign technology or direct import. As an emerging instry, if talents are equally important in the field of blockchain, but we do not pay attention to the cultivation of talents, the future of blockchain will be restricted by developed countries just like many traditional instries because of talents.
6. The name blockchain as a "machine of trust" originated from an article in the economist. From the macro level, the Internet is a network for transmitting information. Today, we can shop through the Internet and send wechat. Now many technical experts and people in the traditional financial instry all over the world regard blockchain as a revolutionary technology because blockchain is a network for transmitting transactions. Therefore, a famous VC in the United States says that blockchain is the underlying protocol of finance
suppose that one user a wants to transfer money to another user B, what are the differences between traditional financial networks and blockchain networks? In today's existing financial network, such as transferring money from ICBC to China Merchants Bank, users can first access the database through ICBC's online banking or ATM, and the database can go through the clearing company of the blockchain center to the database of another bank, and then users receive the money. If the transaction is made on the blockchain, first of all, the transaction will be broadcast to a decentralized network or P2P network. The transaction will be verified by the bookkeeper elected by some mathematical mechanism on the network to verify whether the transaction is true. It ensures that the transaction can not be forged in principle through mathematical algorithm. When the bookkeeper agrees that the transaction is valid, it will form an account book and broadcast the account book to all people on the network, including the payee of course
centralized network, which is the earliest and most primitive network. Today's Internet is a distributed network. It has many small centers connected by backbone network to form a distributed network. The blockchain network is actually a very inefficient network, because the network has a lot of data rendancy, and the transmission is not very effective. But with the development of time, after the transmission becomes stronger, the rendancy problem is not a big problem
there is no strong center in the blockchain network to control or tamper with the data in the network. We can understand that the decentralized network is a kind of network built on the distributed network. In many countries, such as many reports made by the Bank of England, blockchain is also translated into distributed books. Blockchain originated from bitcoin. Now many traditional financial enterprises begin to study blockchain and try blockchain, such as ripple and R3 alliance
if we carefully analyze the role of distributed ledger such as blockchain, we can find that it has many applications. For example, in the field of personal finance, there are many payment companies and remittance companies based on blockchain. At the political level, there are those who apply blockchain technology to elections, which can technically ensure that votes cannot be tampered with. In the digital money field, England bank uses block chain technology to develop another digital currency, which is different from the balance of Alipay and internet bank. Of course, it is not an uncontrolled currency like bitcoin. Its issuing right is still in the hands of the central bank, but its clearing and circulation network is built on the opened blockchain network. Its advantages, such as our WeChat payment and Alipay can transfer each other. For example, when I run a parking card, the original system naturally forms some payment barriers, and the underlying digital technology can eliminate these barriers. IBM and others are trying to do this
another example is R3, which is an excellent company in the world. They try to build a clearing network for credit bonds and bank bonds. Domestic clearing companies are all sincere clearing companies. In fact, there is no such clearing center in the world. First, several large domestic banks carry out communication protocols, and then small banks make agreements in them. It's very complicated. Because there is no strong center in the world that can build an international settlement system, not even the world bank. Enterprises like R3 try to use technology to do it. In the world, countries do not trust each other, or banks trust each other. But we can all believe in technology. Blockchain is such a technology
we have also done some innovative work in this field. We started with the first application of bitcoin in blockchain. Our proct is called okcoin bank. This year, we launched a new blockchain financial network oklink. Oklink procts are mainly used for small amount of international remittance in Hong Kong
as we all know, there is a multi-layer capital flow in the world, and the separation of capital flow and information flow leads to a very high cost of international remittance. There is a prediction in the world that many people work outside and remit their money back to US $700 billion a year. A single sum is small, and the average handling charge is 10%. For example, Filipino domestic helpers earn 4000 Hong Kong dollars a month in Hong Kong, but they don't have 800 yuan when they get home
okcoin has put many companies in the blockchain, which can make them clear efficiently and at low cost, but they will not make false accounts, and they are not able to run. At present, we have opened up more than ten countries in the world. At present, there is no China. Only banks in China can legally transfer money. Blockchain has helped our enterprise to establish a credit in the world, which is not the credit of our company or investors, but the credit of technology. Therefore, we have some partners in Africa and Southeast Asia who are willing to believe in the security and resonance of the network
at the same time, we have an app at the C end to distribute remittance orders from all over the world to these remittance enterprises. At present, we are commercializing the blockchain operation network in the world. Every month, we have millions of dollars of processing amount, and all countries in the world are in compliance
summarize what blockchain technology can do. Blockchain technology is actually a technology to open your account book to the public. When do we need to open our books to the public? When others don't believe in your platform, its application is more suitable for areas with weak credibility in the short term. But in the long run, units with their own credit, such as NASDAQ and the New York Stock Exchange, will also use blockchain technology in the future. Because the current cost is very high, in the long run, such units with strong credit may use blockchain technology to rece costs in the future (Netease News)
of course, bitcoin, Ethereum, and decent are the same.

7. Blockchain is an important concept of bitcoin. In essence, it is a decentralized 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
in a narrow sense, blockchain is a kind of chained data structure, which is composed of data blocks connected in sequence according to the time sequence, and is a distributed account that can not be tampered with and forged by cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm, 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
blockchain and big blockchain are not the same concept. Big blockchain should be the name of a company. Bitcoin, Ethereum and decent are all successful cases of blockchain technology.

8. Looking back at the development of science and technology in 2016, the decline of wearable devices is obvious. Business insider, an American business media, made a very bold judgment in a recent review article that "wearable devices are dead"
to be honest, I quite agree
three years ago, the instry generally believed that wearable devices would set off the next wave of technology, replacing smart phones as a new hardware platform. Three years later, the instry's expectation of wearable devices did not come true, but saw the opposite result
is there a chain technology in Qing, as well as in large blocks?
