Founder of blockchain co Heng B & B
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

I. blockchain 1.0 cryptocurrency era (2008-2013)
&
in 2008, Nakamoto first proposed the concepts of bitcoin and blockchain, and then in January 2009, the first blockchain came out. At this stage, people pay more attention to the transaction of cryptocurrency, and blockchain is only used as the underlying technology to act as a "public account book"< br />
2. Blockchain 2.0 smart contract era (2014-2017)
&
in 2014, & quot; Blockchain 2.0 "has become the pronoun of decentralized blockchain database. At this stage, people mainly focus on the application of the platform. Anyone can upload and execute the smart contract on the blockchain, and will be rewarded automatically after the execution. Because this transaction process does not need any intermediary, so people's privacy has been greatly protected< br />
III. blockchain 3.0 large scale application era (2018 -)
&
at this stage, people begin to build a completely decentralized data network, and the application of blockchain technology is no longer limited to the economic field, but expanded to the fields of art, law, real estate, hospital, human resources and so on.
If the time is t, the landing velocity is V, and the impact force is f. It can be calculated by the formula ft = MV
objects that fall only under the action of gravity without any resistance are called & quot; Free fall & quot;. An object, such as one that begins to fall from a static state under the action of the earth's gravity. The sky near the earth's surface can be regarded as a constant gravitational field. If the atmospheric resistance is not taken into account, the motion of the free falling body in this region is uniformly accelerated linear motion. Its acceleration is equal to the acceleration of gravity G
extended data:
the main characteristics of free falling body
the characteristics of free falling body motion are reflected in the word "free", which means that the object is stationary when it begins to fall, that is, the initial velocity v = 0. If the initial velocity of the object is not zero, even if it falls vertically, it cannot be regarded as a free falling body
(2) in the process of falling, the object is not affected by any other external forces (including air resistance) except gravity, and the resultant force of external forces is 0
(3) the falling time of any object is the same when it falls freely at the same heightsource of reference:
network free fall
Dongyang Public Security Bureau of Zhejiang Province immediately started the investigation and found that Qiao was not the only one who suffered losses. Through efforts, the police of the special task force determined the identity of the manager of the GBL trading platform and implemented the pursuit in time. The first case of fraud on bitcoin trading platform in China was solved
lawyer analysis:
Zhang Yanlai, senior special researcher of China e-commerce research center and lawyer of Zhejiang Jin law firm, believes that virtual currency is not a new concept. Q-coin and online game currency have long been known by people. However, the emergence of bitcoin once again makes people realize the power of virtual currency. Compared with the traditional q-coin, the biggest feature of bitcoin is that it does not have a unified issuing agency. The generation of bitcoin completely depends on computer algorithms, and anyone can participate in the issuance of bitcoin
this makes it difficult to trace the source of bitcoin, which makes it a real virtual currency. The anonymity, cross-border and other Internet genes of bitcoin make people see a new form of currency that may circulate in the future society, so the pursuit and use of bitcoin also continued to rise in 2013. Some foreign governments have recognized the legal status of bitcoin. In China, some online stores have begun to use bitcoin for trading. Restaurants that accept "bitcoin" consumption have appeared in Beijing. The first "bitcoin" investment fund in China is also being raised. After the Ya'an earthquake, one foundation has received a total of 65 bitcoin donations, with a market price of about 50000 yuan
of course, money laundering, fraud, gambling and so on will follow. This case is a typical case of fraud under the banner of bitcoin trading. As the first case of bitcoin fraud in China, the public security organs have also concted in-depth study and understanding of the professional knowledge related to bitcoin, and finally cracked the case. On December 5, 2013, the people's Bank of China, the Ministry of instry and information technology and other five ministries and commissions issued the notice on prevention of bitcoin risk, which first made it clear that bitcoin does not have the status of legal tender, and required financial institutions and Payment institutions not to price procts or services with bitcoin. The central bank believes that there are three risks in bitcoin Trading: high speculative risk; High risk of money laundering and being used by criminals or organizations. In the future, the future of bitcoin is not clear, especially in sovereign countries, which will take a prudent and conservative attitude towards currency, which involves financial order and national security. Therefore, the public should also raise enough risk awareness.
data storage and computing tasks respectively. In the client, the user data is encrypted into blocks, and each
part will enter a different storage node, and the hash credentials will be uploaded to all nodes in the blockchain network, so that the data can be
verified, confirmed, and so on. The parallel distributed architecture separates the data layer from the blockchain, which not only ensures the security and centrality of the blockchain system, but also improves the scalability of the system and greatly reces the size of the block
at present, many blockchain platforms are facing the problem of capacity expansion, such as: block capacity, but only increasing the block capacity
will increase the maintenance cost of blockchain nodes, resulting in the rection of the number of nodes and the rection of system security. With the system architecture of
wotchain, the number of transactions packed in a single block can be greatly increased under the same block size,
the transaction processing speed of the platform can be greatly improved< Wotchain
for the Internet of things and ecological network, and for all the data that can be obtained, perceived and processed, wotchain
mainly does two things well: the first is to ensure that the data is reliable; The second is to ensure the circulation of data value.
