Using blockchain abroad

1. This is because foreign universities have been paying attention to blockchain technology for a long time. Foreign universities pay more attention to academic, while domestic universities pay more attention to utilitarian. Moreover, foreign countries have a high degree of acceptance of new things, and domestic technology is basically mature and applied, lacking innovation

the well-known blockchain projects such as Ethereum, decent and Ruibo laboratory are all from abroad.

2. 1. Weizhong bank uses blockchain technology for loan clearing
in September 2016, Weizhong bank and Shanghai Huarui bank put into trial operation the inter-bank joint loan clearing platform based on alliance blockchain technology to optimize the settlement and clearing of "micro loan" joint loans of the two banks. With the introction of the blockchain system, all the information is recorded on the blockchain network, which can not be tampered with. The transaction process is cleared at the same time, realizing real-time clearing, saving a lot of manpower and material resources
2. China UnionPay uses blockchain technology to realize inter-bank points exchange
in September 2016, China UnionPay and IBM tried out a shared points system based on blockchain technology. Using this blockchain system allows users to exchange bonus points across banks and platforms. In other words, the bonus points of one bank can be exchanged for bonus points of other banks, or even multiple airline mileage and supermarket awards. It greatly improves the use efficiency of bank points
3. Toyota uses blockchain technology to track auto parts
in October 2016, Toyota joined R3 alliance to store the proction, processing and use of each part in the blockchain through blockchain technology, so that when there is a problem with auto parts, the source of the parts can be easily and quickly found
4. Central bank's blockchain digital bill trading platform
in January 2017, the central bank's blockchain based digital bill trading platform was successfully tested. The introction of digital currency for settlement can realize the synchronous transfer of capital flow and information flow of digital bill transaction, so as to realize DVP bill settlement. At the same time, the blockchain digital identity solution solves the problem of repeated KYC authentication between different financial institutions. It not only solves the problem that the transaction amount of digital bills is confidential to the unrelated parties, but also ensures that the regulatory parties such as the exchange have the mechanism of seeing through when necessary
5. Ant financial services blockchain application
in August 2017, ant financial services blockchain technology tested water insurance and helped Xinmei mutual insurance company to launch the first love rescue account in the domestic insurance instry. Blockchain technology makes every capital flow open and transparent, the data of every capital flow can not be tampered with, and the whereabouts and uses of every capital can be traced. In November of the same year, ant chain was used in food safety traceability and traceability of genuine procts. At present, the milk powder proced in Australia and New Zealand and Moutai in China, users can only know if they are genuine procts by scanning Alipay.
there are many other successful cases at home and abroad, all of which indicate that the application of blockchain technology is graally promoted, and is favored by various instries. Accompanied by the emergence of many blockchain technology companies, they want to take a share in this field. However, after the people's Bank of China and other seven ministries and commissions issued the "notice on preventing the financing risk of token issuance"), with the increasing difficulty of registration, there are more empty shell companies in the intermediary instry chain, and few companies have practical applications
in addition, the security technology of blockchain has always been concerned and controversial. Nowadays, blockchain mainly faces five security problems: the security of underlying code, cryptographic algorithm, consensus mechanism, smart contract and digital wallet.

3. It's said that bgcc is being speculated in foreign blockchain exchanges, so it should be realized in foreign exchanges. We'll start with a little bit, and then we'll make a move. The market value of this bgcc is only 1 yuan now. It is estimated that it is not difficult to increase it 10 times.

4. Some foreign legal blockchain platforms will be regulated in China, and the laws of the two countries are different.

Recently, there are three popular concepts: blockchain, bitcoin and ICO

one is the blockchain, which is the blockchain in Xu Xiaoping's internal letter that "if it goes along, it will prosper, if it goes against, it will die"

the other is that it has been hyped for several years, and the price keeps going up and down, but some people have been advocating bitcoin that "each bitcoin will rise to $10000"

Another is the ICO, which Xue Manzi cheered and advocated a few months ago and later was strongly concerned by the regulatory authorities. On the night of January 12, the day before yesterday, the China Internet Finance Association issued an announcement entitled "risk tips on preventing disguised ICO activities", in which it named the digital currency "chain gram" (formerly "play guest currency") released by Xunlei, saying that it "replaces the legal currency payment obligation for the services contributed by the participants, which is essentially a financing behavior and a disguised ICO". As soon as the news came out, Xunlei's share price fell sharply in the early trading of us time on Friday

"bitcoin" does not solve any problems

besides bitcoin, Xiaotao has always been a loser of bitcoin, because in Xiaotao's view, bitcoin has not solved any new problems. In other words, what would the world lose without bitcoin today? Who and which transactions will be affected? The answer is that no one will be affected except the most special people. What are the advantages of bitcoin over existing currencies? Stable currency? Security? Low cost

the decentralization advocated by bitcoin is nothing more than evading regulation. For example, the goods between the two countries should have gone through the customs. The Customs has eight channels. Now you have an underground channel. Although the distance may be closer and many customs ties may be exempted, it is illegal. It is a typical Arbitrage Behavior to evade supervision. Solving one's own problems on the premise of harming social interests and order is not desirable and can not last

What's more, in order to obtain bitcoin, the huge "mining" workload consumed a lot of power and computer computing power, and did not create any value, which is a huge waste of social resources. It is said that the cost of digging a bitcoin has reached 3000 to 4000 US dollars...

"ICO" is a typical Ponzi scheme

as for ICO, the so-called IPO project with digital currency as the media, sticking to its own hot speculation concept, holding the idea that it is not ready to cash, or the idea that the feasibility is almost invisible, relies on a kind of digital currency that evades the supervision to let people buy and hype the price... This is a typical Ponzi scheme, or open a casino in disguise

there are many such cases in history. A few years ago, some people divided any painting into tens of thousands of shares, marked a price for everyone to buy and hype; Hundreds of years ago, the Dutch were crazy about tulips. A tulip price could buy a castle... Everyone knew that it was a bubble. They all knew that the bubble would burst, but everyone wanted to beggar the neighbour, hoping to get a.

before the bubble burst.

6. DAPP has been widely used since Ethereum's smart contract came out.

7. According to McKinsey's analysis, the impact of blockchain technology is most likely to occur in the main application scenarios of payment and trading banking, capital market and investment banking business
digital currency: to improve the convenience of currency issuance and use, for example, the central bank plans to issue its own digital currency; Cross border payment and settlement: realize point-to-point transaction and rece intermediate costs; Bill and supply chain financial business: rece human intervention, rece costs and operational risks; Securities issuance and Trading: realize quasi real-time asset transfer and accelerate the speed of transaction clearing (European crowdfunding is a typical model); Customer credit investigation and anti fraud: rece the cost of legal compliance and prevent financial crimes.

8. No, many domestic experts have made great achievements. The core team of bitbox is in China, but there are also overseas teams
