1. The characteristics of blockchain ensure that the information can not be tampered with and stored in a decentralized way, which can greatly promote data sharing, optimize business processes, rece operating costs, improve collaboration efficiency, and build a trusted system
at present, many local governments in China are promoting blockchain government application platforms, such as Chongqing's blockchain government service platform, Guangzhou's tax chain platform, Hunan Changsha's SMIC blockchain public service platform, etc
from the perspective of technical characteristics, value and domestic cases, it is very necessary.

bus line: Metro Line 2, the whole journey is about 3.4 km
1. Walk about 10 meters from Beijing station to Beijing station
2. Take Metro Line 2, pass through 2 stations to Qianmen station
3. Walk about 720 meters to the National Museum of China
3. 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.

4.
There have been blockchain projects launched, such as utispace. Blockchain is the general trend of the tuyere project, but in the selection of blockchain projects, we must shine our eyes, we must find a team with technology, application landing and real down-to-earth work. Otherwise, it may come to nothing, because since it is a trend, naturally there are a lot of speculation and fraud projects
here, we mainly introce utispace, the first blockchain distributed storage project with perfect technology and real application in the world
give a brief introction to utispace: is 5g here? Have big data, artificial intelligence, wearable devices, Internet of things and AI entered our lives? Is the phone running out of memory
stuck
the high-speed information flow inevitably needs infinite storage space, but the current storage space is never enough
for example, the storage space of 4G mobile phone determines the price of mobile phone, but what about 5g mobile phone? More to 10 times the demand for 4G space storage, the price will be expensive
where there is demand, there is market. In the past, we need to build a big data storage base station for big data storage. The cost is very high. It costs 10 billion yuan at any time, and the security is very low (the base station will be hot and prone to fire and earthquake, what should we do? If hackers attack all data, they will be paralyzed). In addition, no matter how big the base station is, its storage capacity is limited, and it can never meet the demand of doubling the amount of data generated by the market, resulting in a large number of useful data homeless. At present, 67% of the data has been deleted, which is a great loss
so who can solve the data storage with large storage, high security, low cost and low energy consumption
today, the decentralized distributed storage space of China's own brand utispace, together with the digital pulse chain Laboratory of Zhejiang University, has solved this worldwide problem. Thus, it takes the lead in occupying the big cake of distributed data storage
5. With the increasing maturity of blockchain, more and more enterprises begin to look forward to using this technology for innovation. So, what is the impact of blockchain on enterprises? What can it bring to enterprises<
Renren blockchain technology services
blockchain has the ability to innovate trade, transaction and business processes
the two basic concepts supporting blockchain are "business network" and "account book" -- it is thanks to these two concepts that blockchain can become a wise and unchangeable way of trade, transaction and business process execution
network members exchange various assets through an account book that can be accessed by all members. When the network synchronizes the account book, all members need to confirm the transaction of tangible or intangible assets. This shared view helps to establish legitimacy and transparency, even when the parties are not familiar with each other
blockchain can improve visibility and trust in business
by providing visibility to all participants, blockchain can rece transaction settlement time from days or weeks to seconds. The technology can also eliminate the intermediate third party that is usually needed to verify transactions in the past, so as to rece the excessive cost
because blockchain is built on the concept of trust, it can help enterprises rece the risk of illegal behavior on the payment network, thus helping to rece fraud and cyber crime
speed, cost, efficiency and transparency are the most important advantages of blockchain within enterprises and in the company ecosystem where trade activities are carried out. It is precisely because of such advantages that far sighted enterprises are more looking forward to using blockchain technology to innovate infrastructure and better carry out business
the value of blockchain development lies in the growth of the ecosystem
as a business network, blockchain can accommodate a variety of different types of participants. According to the number of participants in the blockchain network, the value of the assets exchanged, and the need to authorize members with different credentials, the adopters of blockchain technology should pay attention to the differences between "licensed" and "unlicensed" blockchain networks
when these business networks continue to expand, the real value of blockchain will be realized. With a strong ecosystem, business networks can reach critical scale more easily, enabling users to build new business models and innovate transaction processes.

6. Development trend:
1. Development trend of core key technologies
from the point of view of the current technology and application of blockchain, its core is distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other existing computer technologies. With the deepening of blockchain application, new and higher requirements will be put forward for these core technologies. The research results in consensus mechanism, security algorithm, privacy protection and other related technology fields will play an important role in the leapfrog development of blockchain technology and application, and will be very critical to the continuous innovation and breakthrough of these technologies
(1) the development trend of consensus mechanism
in the public chain, the common consensus mechanism has the disadvantages of low performance and high energy consumption“ The "side chain" technology can only solve some problems under certain conditions. At present, most of the mainstream consensus mechanisms in alliance chain are based on pbft and its variants. Although access control can greatly improve the performance, it also sacrifices the efficiency, constraints, fault tolerance and other aspects of the consensus. It can be predicted that consensus algorithms and decision-making with universality and better performance for some typical scenarios will continue to appear
(2) the development trend of security algorithm
security is particularly important for financial application systems. On the one hand, most of the traditional security algorithms currently used have potential "backdoor" risks, which need to be replaced by more secure national security algorithms, and the strength of the algorithms also needs to be upgraded; On the other hand, we should also prevent some new technologies, such as quantum computing, from impacting or even subverting the traditional security algorithms
(3) development trend of privacy protection
at present, the privacy protection related to blockchain is still relatively weak. Especially for sensitive data, we need to balance privacy protection and compliance supervision. Information privacy protection technology, such as zero knowledge proof, homomorphic encryption, is also an important direction of follow-up development
the above core technologies tend to be low-level computer technologies, and their development requires considerable personnel and time investment, which will be a progressive process. The research achievements and cooperation of related enterprises, scientific research institutions and colleges and universities in these fields are very important for the development of blockchain technology
2. Development trend of general development platform
at present, many IT enterprises, consulting companies, communities and technology alliances have invested in the application research and development of blockchain, established and improved the general development platform, which has a great role in promoting the application of the whole blockchain technology
similar to IAAs (infrastructure as a service) and PAAS (platform as a service) of cloud computing, the blockchain general development platform is composed of infrastructure support layer, blockchain core component service layer, and corresponding development test suite, which can provide one-stop, low-cost technical services for building and deploying blockchain applications. At present, there are some such platforms. With the rapid development of blockchain applications and the strong investment of relevant participants, its service coverage, R & D convenience, operation and maintenance intelligence, as well as high stability, large capacity and low cost are the predictable development direction.

7. The first is whether the project can actually solve the problem, the second is whether there are powerful investors, and the third is whether there are powerful operators. There is a SMIC blockchain service platform project initiated by Changsha high tech Zone, which is a blockchain + public service mode, and enterprises are being recruited to join the chain. In the future, relevant enterprise affairs and government affairs can cooperate on the chain. It mainly has the background of state-owned assets.
