1.
In the past, when it comes to blockchain, we always think of foreign procts, such as Ethereum. But when I talk about this topic today, I think more about China's own blockchain technology
at present, the mature application of blockchain technology is more concentrated in some public chain projects, because many application projects need to be developed based on this, so I think the current global landing direction is public chain projects, and it is still too early to talk about maturity. After all, bitcoin and Ethereum are still blocked, and many old problems have not been solved, There will be many new problems. The well-known ones are Biyuan chain, ulord (the project is abroad, but the technical party provides it in the domestic company, Hunan Tianhe Guoyun Co., Ltd.), quantum chain, Xiaoyi Neo, gongxinbao, etc
ulord is a point-to-point value delivery public chain. By building the underlying architecture of blockchain and digital resource distribution protocol, it supports third-party developers to build their own applications on top of their open source protocol, and works with many instry partners to build a complete ecosystem of blockchain technology and applications
based on various rules and protocols created by ulord, it is convenient to graft various digital resource application scenarios including text, pictures, music, video, software, etc., providing a direct docking platform for information creators and consumers. Third party developers can build their own economic system in ulord, or focus on building all kinds of applications around ulord, and use the ulordtoken in ulord as the voucher in the system
for example, an experience sharing platform can be built on ulord, where the experience sharers price the published experience, and the people who obtain the experience information trade on the platform, and each fee paid to the experience sharers will arrive at the account immediately; Proct promoters can publish ads on ulord, price ads, and people who are interested in ads can get certain profits by clicking on ads. The first mock exam is to separate information from the past, and to use platform or other centralized organizations to spread profit. This mode eliminates intermediate links, and information providers and consumers directly connect with Ulord, which ensures the maximization of the interests of the originator. p>
2. From an academic point of view, blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is essentially a decentralized database
for example, if you are a woman, every time your boyfriend says something to you or promises to buy something for you, you immediately record it and send it to you and all his friends, classmates, colleagues, as well as various groups and circles of friends, so that he can no longer deny it. This is called blockchain
the core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
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.

3. Blockchain exchange
you mean platform trading. Domestic illegal, international and mostly deceptive, you find the well-known ones. There is a special introction to blockchain network. Remember to be legal, otherwise you can't withdraw cash and it's useless to make money.

4. 1. Bitcoin
it is the birthplace of blockchain technology, and the market has confidence in it. It still maintains a stable growth under the adverse situation of major policies. Once it solves the problem of capacity expansion, the price rise can be predicted
2. Ethereum
compared with bitcoin, the advantage of Ethereum is that it has no policy problems. Although the event led to its bifurcation, the establishment of enterprise version Ethereum alliance may solve this problem. Its concept and Prospect of smart contract attract many developers to follow
the essence of community operation is that the majority decides the minority when indivials support eth
3. Zec
compared with bitcoin and Ethereum, the risk of z-coin will be greater, and its value will take a longer time to reflect. But in the long run, the value of anonymity will be one of the values that human beings generally pursue
4. BTS
bitstocks are very powerful and the system is very stable. Decentralized trading, anchoring system and so on. Although the founder bm's brain damage has hurt the community, the value of bitstocks is obviously undervalued. It is a wise choice to hold bitstocks on the cheap.

5. Before October 2018, it seems that the fastest one is REBO, next to EOS. After October, these public chains are basically silent in terms of speed, because bitconch of Baker chain has achieved 120000 TPS Based on many technical advantages, which makes it possible for applications to land. Therefore, the world's fastest public chain is the world's fastest public chain, which can be said to be the leader.
6. Currently known blockchain technology classification, jinwowo Group believes that it can be roughly divided into three categories:
1 - public blockchain: refers to the blockchain that anyone can read, send transactions for validity confirmation, and anyone can participate in its consensus process, so as to jointly maintain the security, transparency and tamper proof of public blockchain data
2-community blockchain: also known as alliance chain, it means that the nodes participating in the blockchain are selected in advance, and there are usually good network connections and other cooperative relationships between the nodes
3-private blockchain: the participating nodes only have a limited range, the access and use of data have strict permission management, the write permission is only in the hands of the participants, and the read permission can be opened to the outside world.

7. 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.

8. Blockchain is a very front-end technology of Distributed Accounting, and it will also be a trend in the future. The second question you asked is based on Ethereum smart contract, and the underlying technology is also based on blockchain. Moreover, the scope is global and valuable. I hope the answer can help you.
