blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
blockchain is an important concept of bitcoin. In essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
extended data
according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:
1. The blockchain with the whole network open and without user authorization mechanism is called public chain
2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain
3. All the nodes in the network are in the hands of one organization, which is called private chain
alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain
blockchain features
1, decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain
2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention
4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously
There is no doubt that blockchain has development prospects, and the necessary condition for development prospects is to enter the mainstream market
North America blockchain infrastructure the oan (former aion network) founder and CEO Matt spoke published an article entitled "in order to successfully enter the mainstream market, blockchain projects must" eat dog food "in Forbes on July 24, in which Matt mentioned his views on how blockchain should enter the mainstream market - & quot; Eat dog food
in the science and technology circle, there is a jargon called & quot; Eat dog food Dogfood (also known as eating your own dog food) refers to companies using their own procts and becoming users of their own procts. Many high growth companies (such as Microsoft, Facebook, Amazon, apple, Netflix and Google) also test their procts by "eating dog food" or help build credibility“ "Eat dog food" is often used to find and fix bugs, but it has another value: to create reliable use cases for the company's procts
this is worth learning from blockchain projects, because blockchain projects often hold & quot; Once built, they (users) will come naturally, which habitually leaves the responsibility of creating new and interesting blockchain applications to a third party
this attitude is very common, even the well-known blockchain summit consensus 2019 also held a conference entitled & quot; Once built, they (users) will naturally come: to build a global blockchain Center & quot; To discuss how governments around the world can make efforts to attract blockchain projects while balancing regulatory, investment and innovation needs
to be fair, this strategy may be effective for blockchains that only focus on people in the currency circle. For the security token, especially for the exchange represented by the transaction, it makes more sense - "supply creates demand" is the usual idea here, especially considering that the realization of these transactions requires the construction of complex infrastructure
in contrast, "eat dog food" is more likely to be adopted by blockchain project developers who seek mainstream audiences (such as those in financial instry, manufacturing and supply chain, identity management, etc.). If blockchain technology wants to enter these mainstream fields, blockchain companies must first "eat dog food". This can not only clearly prove that blockchain technology is feasible outside the coin circle, but also highlight that blockchain can not only optimize existing use cases, but also create new use cases
and the oan team has been adhering to this concept, and relying on the oan and aion's technology stack built over the years, it has developed a financial technology platform moves for independent workers
Matt said that in the development and development of moves, the team hopes that the relevant functions of the OAN blockchain network can be brought into full play, so it will focus on the following three aspects:
1. How to use the OAN blockchain network to improve the credit efficiency of the proct there are two main considerations to improve credit efficiency: 1) can we use the mechanism of the defi market to rece the cost of capital; 2) Can the blockchain technology be used to increase the external trust in the credit process of moves. Here, moves will form a mechanism of "pooling wisdom", so that everyone can contribute to recing credit risk and increasing the credibility of credit process, and may even develop a micro guarantee mechanism in the future. Therefore, users will be able to participate in the market established by the platform as borrowers, lenders or guarantors
specifically, by connecting moves with the oan network, and with the help of digital asset aion, a relationship of interest consistency is formed between procts and users, so that users can personally experience the success of moves procts and directly participate in the oan, a blockchain network supporting moves
3. How to create the first open system of financial reputation data with moves
this open system may become a substitute for traditional credit scores or related mechanisms. Over the years, banks and financial institutions have been using Equifax, Fico or other similar institutions' scores as risk indicators, and the moves team believes that the procts they are building will be a good start - the beginning of a more perfect and modern financial reputation system. This is a long-term goal
moves supports North American mainstream carpooling, take out and other casual work economic platforms, and will be the flagship open application developed by the oan on its blockchain network. In June, moves expanded its operations from Ontario to Alberta and British Columbia into western Canada
all the initiatives of the oan team adhere to the spirit of "eating dog food" and strive to make blockchain technology enter the mainstream market as soon as possible. Blockchain is not for the minority, but for the mainstream. In addition to the oan team, many projects and institutions in the blockchain instry are also aiming at this goal. Can you say that such an excellent and targeted blockchain has no development prospects
At present, companies in medical, government, transportation, technology, manufacturing, entertainment, games and other fields are already using blockchain technology. As shown in the figure below, blockchain has proved to be very useful in various fields. Currently, the listed companies using blockchain include Facebook, Alibaba group, Microsoft, Siemens, Ford Motor Company, etc
According to reports, the coin circle, which has been silent for a long time e to the bear market, has been broken recently. This time, Li Xiaolai, who is known as the "richest man in the coin circle" by the outside world, is still standing at the muzzle of the gun
on July 4, 2018, a recording of Li Xiaolai's private conversation spread on the Internet. In this conversation, which lasted for more than 50 minutes, Li Xiaolai denounced the well-known figures and blockchain projects in the coin circle in a vulgar tone, and told the interviewees about his investment tactics as a winner
this recording sounds like an explosion of information, which once again pushed Li Xiaolai to the forefront of public opinion. Due to the sensitive words mentioned in the recording, such as "don't blindly believe in value investment", "sell air currency" and so on, Li Xiaolai was identified as the banker of "cutting leeks" in the currency circle in the later public opinion
at the same time, as a former New Oriental teacher and best-selling author, Li Xiaolai has many fans after entering the blockchain instry. But in that recording, Li Xiaolai thinks that his IP and traffic are very important in the coin circle, while disdaining blind followers
What kind of person is the real Li Xiaolai? What is his way of accumulating real wealth and investing in blockchain? What kind of world is the blockchain instry todayon July 12, 2018, Li Xiaolai received an exclusive interview with the media and responded to questions from the outside world
media: who are you most optimistic about in the blockchain instry
Li Xiaolai: Wu Jihan in mainland China. I think this person is a wounded and bloody soldier in the blockchain instry. About three years ago, I told my friends about it. If there is an opponent in the world that I may not be able to fight, it is Wu Jihan. It's just that we're not on the same track, so it's also my luck
media: your little Luo Yonghao is working hard in instry, and you are working in blockchain. What do you think of the relationship between blockchain and entities
Li Xiaolai: finance is the embodiment of real economy. Finance cannot be separated from the existence of real economy. Blockchain will certainly drive the real instry, but it is still unknown how to drive itI admire Luo Yonghao's work in the real instry. He has a higher sense of happiness than me, because making a mobile phone has a much greater sense of achievement than I do in an unknown instry, and they are more easily recognized by the society
media: did Luo Yonghao comfort you after the recording leakage
Li Xiaolai: our habit is to keep quiet when we are in trouble, because how to comfort others is a very difficult thing. But then we'll talk to each other about what happened
Li Xiaolai: do you have any other questions? Today is my birthday. I'll have dinner with my wife latercontent source: phoenix.com
for example, blockchain can be applied to P2P, bills, securities and other financial fields, as well as contracts. Of course, it can also protect intellectual property rights, such as distributed content publishing platform decent

future trend
1. In November 2016, the central bank prepared digital currency, and it is likely that cash will not exist in ten years
2. In November 2016, China digital currency Research Institute was established to cultivate high-level talents of digital currency, carry out digital currency research, consultation, development planning and related activities. It is a non-profit unit with legal license approved by relevant ministries and commissions, and is committed to promoting the integrated development of scientific research and practice of digital currency instry
Up to now, Hangzhou City, Shenzhen City and Guizhou Province have become the three hot areas for the central bank's digital currency pilot. It is reported that Hangzhou is actively promoting the planning and construction of Qiantang River financial harbor, including the blockchain instry. Hangzhou will build the first blockchain Instrial Park in China, which is located in the Internet Finance town of Xihu District, surrounded by ant financial services, e-commerce bank, Zhejiang University and its science and Technology Park and other well-known enterprises and parks legislation
in August 2018, Elina sidorenko, an official of Russia's digital currency risk assessment department, wrote in her own telegram that a Russian digital currency bill, which takes into account social comments and the interests of enterprises and financial institutions, will be issued soon, and will clarify the rights, responsibilities and obligations of relevant participants in digital currency
It's about RMB 0.1, but it can't be used for cash withdrawal. It can only be used for virtual games
global currency is a kind of currency similar to bitcoin. A virtual currency, not protected by law. Five ministries and commissions, including the China Banking and Insurance Regulatory Commission, jointly issued the "risk warning on preventing illegal fund-raising in the name of virtual currency and blockchain", pointing out that many criminals, under the banner of financial innovation, use virtual currency, blockchain, digital currency and other projects to speculate and fund-raising, even to engage in fraud, pyramid schemes and other illegal activities
the majority of investors rationally treat blockchain, virtual currency and other investment projects, establish a correct and rational investment concept, recognize the risk level, and then improve the risk awareness
The biggest advantage of bitcoin is that it is a decentralized digital currency, which is not controlled by anyone. Bitcoin holders do not need to report to the central government, but this may not be the case with globalcoinunlike bitcoin, Facebook's globalcoin will be controlled by the social media company. Because Facebook will be entitled to the identity of all those who hold its digital currency. Globalcoin has forgotten the anonymity of digital money
Sun Yuchen's sudden cancellation of lunch with Buffett is the biggest joke of the year
more than a month ago, BoChang CEO sun Yuchen used more than 30 million yuan to shoot the sky high price lunch of billionaire Warren Buffet. The lunch time is scheled for July 25. However, this morning, sun Yuchen suddenly tweeted that he canceled the lunch e to kidney stones
a twitter user suggested that sun can ask Buffett if he regrets not investing in apple, Microsoft, Amazon, Google, Netflix and Facebook earlier. Now encryption is still in its infancy, he said. If Mr. Buffett doesn't invest in bitcoin and cryptocurrency now, he may regret missing the same early technology opportunities as those above
In fact, it's a pity that Mr. Buffett didn't invest in Amazon many years ago. In May, Mr. Buffett said: "I've always been a fool and didn't buy [Amazon's stock] earlier." Earlier, he revealed that he had bought shares in AmazonSUN Yuchen: I would like to tell Warren Buffett that the whole encryption instry of Amway is excited about the coming lunch, but Sun said that it is unrealistic to think that one meal can change Warren Buffett's idea of encryption
it may be unrealistic to persuade Warren Buffett to buy cryptocurrency in just three hours. But we want to show him the latest developments in cryptocurrency and blockchain technology. "
although many people initially worried that sun Yuchen would use the lunch to promote his wave currency to Buffett, he insisted that he would present the whole encryption ecosystem to Buffett
SUN Yuchen said that not only wave field, but also encryption and blockchain, that is, the whole instry. Our goal is to decentralize the Internet
