Tiktok can be called block chain

1. During September 4-7, 2019, CIOE will hold relevant meetings. The following is an introction to the 2018 Asia Pacific blockchain and artificial intelligence Innovation Forum exhibition last year. I believe that the exhibition in 2019 will be more professional and breakthrough
APCA (Asia Pacific cloud application alliance) and bcai (Asia Pacific blockchain and artificial intelligence innovation and Application Research Institute) will jointly hold the "2018 Asia Pacific blockchain and artificial intelligence Innovation Forum (Shenzhen)" in the conference hall of hall 3 of Shenzhen Convention and Exhibition Center on the afternoon of September 6, 2018 (Thursday)

blockchain block chain is considered to be the fourth generation of disruptive core technology after steam engine, electric power and Internet. As a machine for building trust, blockchain will completely change the way of value transmission of the whole human society, making the information internet a value Internet

blockchain is of revolutionary significance. It will reshape the fulcrum of the world economy. Because it uses decentralized disruptive technology, it can "reshape instry services and business architecture". As the most popular vocabulary, blockchain technology has rapidly gathered the high focus of the government, science and technology and financial circles

in 2016, the Chinese government wrote "artificial intelligence and blockchain" into the 13th five year plan, and blockchain technology was listed in the National Informatization Plan of the Chinese government for the first time. At the present stage, AI and blockchain technology are paid more and more attention by government agencies and international organizations. In 2018, artificial intelligence will affect our lives in a tangible way. In 2018, artificial intelligence will become the mainstream and begin to influence all aspects of our lives in a truly ubiquitous and meaningful way

in order to further promote the innovative application and development of blockchain technology and artificial intelligence technology, let blockchain technology serve the real instry and digital economy, further promote the instrialization process of blockchain technology and artificial intelligence technology, and serve the public entrepreneurship and innovation, APCA and bcai will invite BC and AI experts from Silicon Valley, Singapore, Hong Kong, Tokyo, Beijing, Shanghai, Guangzhou and Shenzhen as well as manufacturers of excellent technologies, procts and solutions to participate in this forum, The forum will exchange and introce the relevant innovative applications and development trends with the participants, so as to help enterprises better participate in the field of blockchain applications and artificial intelligence applications and obtain greater development opportunities. At the same time, interpret the pitfalls and opportunities in the application, and help enterprises realize the marketization and digital capitalization of blockchain technology and artificial intelligence technology procts
nowadays, the innovative application of blockchain is a great force. It can provide a trust tool to expand the global business opportunities of enterprises
nowadays, the innovative application of artificial intelligence is an outlet, which can provide an intelligent service and facilitate people's work and life
when blockchain 3.0 / 4.0 comes, are you still hesitating and waiting
when neural network computing is applied, you haven't got on the bus yet

the future has come, are you here?

2. Blockchain is composed of a series of block links generated by cryptographic algorithm, so it is called blockchain
each block is filled with transaction records, and the blocks are connected in sequence to form a chain structure, which is the blockchain ledger
blockchain technology divides the data to be stored in the database into different blocks. Taking bitcoin as an example, when miners generate new blocks, they need to calculate the new hash value and random number according to the hash value of the previous block, the new transaction block and the random number. Each block is linked to the back of the previous block through specific information, and connected in chronological order to present a complete set of data. In other words, each block is generated on the basis of the previous block data, which ensures the uniqueness of the blockchain data
each blockchain database is essentially an event chain connected in chronological order, which uses the cryptographic mechanism specified in the protocol for authentication to ensure that it will not be tampered with or forged. With the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry
blockchain technology has three obvious characteristics: openness, security and uniqueness
openness mainly refers to that the stored information in the blockchain is completely open to all participants. This is mainly determined by the point-to-point network storage mode of the blockchain. In the blockchain network, each node can store a of the blockchain, and the uniqueness of the blockchain can ensure that the is exactly the same between different nodes
security mainly refers to that the information stored in the blockchain block is saved after being processed by digital encryption technology, and only the private key holder can decrypt the information to obtain the real information. Other members can only see and verify the integrity and uniqueness of information, but cannot see the real information
uniqueness is mainly e to the fact that the information on the blockchain cannot be tampered with once it is on the chain, so it is unique. Of course, the uniqueness here also includes the uniqueness in space, that is, all nodes have only one version of information, and also includes the uniqueness in time, that is, the historical data cannot be changed. This uniqueness also means that the blockchain maintains the characteristics of a unique main chain in the process of operation, and once other chains appear, it is a bifurcation. The emergence of bifurcation will lead to the plication of blockchain in two different spatial dimensions. Of course, to solve this problem, we need to set reasonable consensus rules to avoid
there is no distinction between mobile and non mobile end in blockchain, and if there is one, it is also a gimmick.

3. QQ coin is a kind of virtual currency issued by Tencent in order to facilitate users to purchase the virtual goods and services it provides. Its official price is: 1q coin = 1 yuan. However, if the amount of recharge is large, there will be a certain amount of discount on some recharge platforms
it should be noted that this is the recharge price. If it's selling q-coin, because q-coin recycling is now done by some third-party platforms, there will be a certain cost. Therefore, the recovery price of Q coin is generally lower than the recharge price, remember!

4. There is no need to specify the browser, as long as you enter the official website of star guest, you can access it in any browser normally.

5. 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.

6. Learning from blockchain, the fate will change and develop in a good direction. Indivials can sign up to study the block chain consultant certificate, and have many choices in the future high salary employment. For enterprises, hashton business school can make enterprises to a higher level.

7. Talk about love

8. The content of blockchain science popularization can be published, and other evidences are not clear. The application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.
