The hardware equipment includes mining machinery, ore pool, chip manufacturer, etc; General technologies include distributed storage, decentralized transaction, data service, distributed computing and other related technologies
the downstream application fields include the combination of application blockchain technology and existing instries, mainly including financial instry, logistics instry, right protection, medical health, instrial energy and many other fields. As an emerging technology, blockchain has many downstream application fields and great development potential
the application and service of midstream blockchain includes the construction of infrastructure platform and the provision of technical service support. The construction of infrastructure platform is divided into general infrastructure chain and vertical domain infrastructure chain; Technical service support includes technical support and service support. Similar to upstream technology, technical support is responsible for providing buyers with a series of technical support based on blockchain procts, such as blockchain security protection; Service support includes a series of services such as digital asset trading place, digital asset storage, media community, etc
analysis of instrial chain of blockchain instry
1. Litcoin (LTC) is an improved version of digital currency inspired by bitcoin (BTC). It was designed and implemented by a programmer who worked in Google. It was released on November 9, 2011. Lightcoin and bitcoin have the same implementation principle in technology, but the creation and transfer of lightcoin is based on an open source encryption protocol, which is not managed by any central organization
2. Sunshine coin (SSC for short) is sponsored by Liu Chunyang, vice president of Jinhua express delivery Association of Zhejiang Province, instrial entrepreneur and philanthropist of express delivery instry. As a legal person, Zhejiang Dongyang Yueyin Technology Co., Ltd. is registered with the formal instry and Commerce Bureau, with a registered capital of 10 million yuan. With this as the backing and support, the sunshine elite team affiliated to the company launched the first virtual coin sunshine coin
The English name of Vicat is onecoin, which is a kind of Internet virtual currency term created by the government and is suspected of pyramid selling fraudin 2017, CCTV announced the list of 350 fund pyramid schemes, with Vicat in the list
in May 2018, Zhuzhou County Procuratorate of Hunan Province prosecuted the last four suspects involved in the third batch of the "3.15" Vicat money online pyramid scheme case supervised by the Ministry of public security to the court
4. Amazon coin
Amazon announced in early February 2013 that it is expected to launch Amazon coins in the United States in May 2013. Amazon coins is a new virtual currency that allows U.S. users to buy apps, games and props in the kindle fire. Amazon will provide tens of millions of US dollars of Amazon coins at that time to let users try and consume the apps, games and props in the app on the kindle fire for free
5. Eth is a kind of digital token of ethereum, which is regarded as "bitcoin version 2.0". It adopts the blockchain technology "Ethereum", which is different from bitcoin. It is an open-source public blockchain platform with intelligent contract results, and a resonance network composed of thousands of computers around the world. Developers need to pay eth to support the application. Like other digital currencies, ether currency can be bought and sold on the trading platform
Bitcoin uses SHA-256 encryption algorithm. When mining, it competes with computing power. In order to improve computing power, bitcoin has gone through four stages: CPU mining, GPU mining, FPGA mining and now ASIC mining machine mining, and the degree of specialization is getting higher and higher
Ethereum uses the ethash encryption algorithm. In the process of mining, it needs to read the memory and store the DAG file. Because the bandwidth of each read memory is limited, and the existing computer technology is difficult to have a qualitative breakthrough in this problem, so no matter how to improve the computing efficiency of the computer, the memory read efficiency will not be greatly improved. Therefore, in a sense, Ethereum's ethash encryption algorithm is ASIC resistant.
different encryption algorithms lead to great differences in mining equipment and computing power between bitcoin and Ethereum
at present, bitcoin mining equipment is mainly ASIC mining machine with a very high degree of specialization. The maximum computing power of a single mining machine is 110t / s, and the scale of computing power of the whole network is more than 120eh / s
the main mining equipment of Ethereum is video card miner, and there are very few specialized ASIC miner. On the one hand, the "ASIC resistance" of Ethereum mining algorithm improves the threshold of developing ASIC miner. On the other hand, after Ethereum is upgraded to 2.0, the consensus mechanism will be transformed into POS, and the miner can not continue mining
compared with the ASIC miner, the graphics card miner has two orders of magnitude difference in computing power. At present, the computing power of mainstream graphics card miner (8 cards) is about 420mh / s, and that of Ethereum is about 230th / s.
from the time dimension of the past two years, bitcoin's computing power of the whole network is growing rapidly, while Ethereum's computing power of the whole network is growing relatively slowly
The ASIC mining machine of
bitcoin is monopolized by several major mining machine manufacturers, and miners can only buy it from the market; Although the graphics card miner of Ethereum is also manufactured by a special miner, the miner can buy accessories from the market and assemble them according to his own demand
compared with the existing cloud computing, fog computing does not rely on the remote server located in the central computer room, but intelligently connects to the nearest distributed computer resources, so as to achieve the most efficient utilization of computing resources. This topology is characterized by decentralized peer-to-peer network, which is a perfect match with blockchain. If cloud computing represents efficient computing power in the Internet era, then in the era of Internet of things and value networking blockchain, fog computing should be the most efficient way of computing power networking
therefore, compared with the evolution of cloud computing, which is a kind of centralized computing, fog computing is to share computing tasks with all kinds of powerful devices around us, and realize the evolution of decentralized and distributed computing, which coincides with the philosophy of blockchain itself. However, it is necessary to encourage the owners of distributed computing resources to contribute computing power to the fog computing network. It is not only difficult for centralized enterprises (such as Cisco) to organize supply and demand market settlement in real time and monopolize, but also contrary to the decentralized distributed philosophy of fog computing itself, which is difficult to be widely recognized, It is difficult to find a satisfactory solution on how to settle the compensation of fog calculation reasonably
we can see that Amazon's AWS, Microsoft's azure and Alibaba's aliyun are all centralized operators operating centralized computing services, and the combination of blockchain value network and cloud computing network, which are both decentralized philosophy, is almost perfect. Ethereumfog is born for this purpose. Upgrading Ethereum based on Ethereum will really bring fog computing to us. In the near future, many personal computing devices may contribute their computing power to do useful things on ethereumfog chain, and do not waste every resource to earn corresponding returns< We use cloud computing, but it runs in the remote data center; Fog is close to the ground and lingers around us. Fog computing makes both computing and storage decentralized distributed on the devices around us. The combination of blockchain and value Internet makes more people willing to let their computing resources participate in it. The organic combination of supply and demand is becoming more powerful. Ethereumfog etherfog (ETF) is opening the door to the new world of Ethereum.
Lao Xue has always been conservative about e-money investment. Listening to what my friend said, I don't think it's very reliable, so I paid close attention to it. It doesn't matter if you don't look at it. I really found some twists and turns in it<
let's talk about its issuer first:
FVI (finatech capital investment) is a cryptocurrency fund company from the Netherlands, which was founded in 2016, focusing on the investment of blockchain technology, cryptocurrency and related assets
the company claims to have offices in the United States, Australia and Hong Kong. It has previously launched bitcoin contracts (456% of profits) and Ethereum contracts (the current contract period is not expired, but it claims to have positive profits). This sale is the company's new project ICO contract - Ethereum payment
what is etheric payment?? I found the relevant white papers and dozens of pages of PDF documents. I was dazzled by them. After studying them all afternoon, I finally understood that the so-called Ethernet payment is not only the name of electronic currency, but also the name of a transnational electronic payment project
according to the white paper, Ethereum is a general decentralized market based on Ethereum blockchain. In short, it is a Taobao or Amazon that can pay with e-money, and there is also a debit card for Ethereum, which can be used for cross-border consumption and can withdraw the e-money at any time. The most important thing is to pay through Ethernet. The service charge of online or cross-border payment is only 0.88%, which is lower than that of traditional e-commerce or bank
as an investment project, the most attractive thing is its income. Taifu private placement project plans to issue 800 million tokens, accounting for 80% of the total issue. The private placement period is one year, and the starting price is $1.00, which is expected to rise to $6.40 after the lock-in period (52 weeks), so if the first batch of purchase income is considerable
but Lao Xue, I'm a professional at least. As soon as I say that, my career sensitivity tells me that etherpay is not as beautiful as it says
for the online payment and cross-border payment claimed in the white paper, I can't tell the authenticity of such a large project for a moment, but I'm sure it's a difficult problem to realize it. First of all, cross-border payment and ether payment debit card have basically crossed the bottom line of central banks. E-money is not recognized by all countries. In addition to the possible capital outflow caused by cross-border payment and the impact on traditional commercial banking business, I think our central bank can not pass this pass. Let's talk about online shopping and e-commerce, because etherpay is equivalent to re establishing an independent payment platform, which can move the cake of traditional Internet giants. It will be fresh for Ma Yun and Bezos to watch it thrive and grab their own jobs
there are many difficulties in realizing the "lofty ideal" of this project, so whether this project can achieve this degree of profitability naturally has to be questioned. The project is unreliable. Isn't there a way to sell tokens? Let's study token appreciation
since the whole project is based on Ethereum technology environment, it is natural to check on Ethereum before investment. As a result, the white paper says the name of the token on Ethereum - ethepay, and it has been put on sale since August this year. It should be valuable now, but the value of ethepay found on Ethereum's website is at present $0@0Eth In other words, at present, the intrinsic value of aether payment token is "air"
in order to avoid my mistake, Lao Xue checked all the links similar to ethepay and Epay (including the differences between case and case), and found that all the links had zero value. I doubt that the etherpay project is an "air currency" ICO project in the final analysis, but the packaging is more realistic and advanced
seeing this, we should understand what is the situation of the etheric payment. The project itself and the future appreciation space of the token are basically impossible to make money. If we rely on the development of the MLM mode to get the Commission, we can still make some money. So whether you can participate or not depends on your IQ and conscience.
Digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields besides digital currency , which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market, financial stability and so on. Specific Wu Xiaoxia:
1. Impact on monetary policy
if digital currency is widely accepted and can play the role of currency, it will weaken the effectiveness of monetary policy and bring difficulties to policy-making
because digital currency issuers are usually unregulated third parties, money is created outside the banking system, and the amount of circulation depends entirely on the wishes of the issuers, which will lead to the instability of money supply. In addition, the authorities are unable to monitor the issuance and circulation of digital currency, which will lead to the inability to accurately judge the economic operation and bring trouble to policy-making, At the same time, it will weaken the effectiveness of policy transmission and implementation
2. Impact on financial infrastructure. The use of distributed ledgers also poses challenges to trading, clearing and settlement, as it promotes the disintermediation of traditional service providers in different markets and infrastructures. These changes may have potential impacts on market infrastructure other than retail payment systems, such as large payment systems, securities settlement systems or trading databases
3. The impact on financial intermediation and financial market in a broad sense. As a financial intermediary, banks perform the ties of acting supervisors and supervise borrowers on behalf of depositors
generally, banks also carry out liquidity and maturity conversion business to realize the financing from depositors to borrowers. If digital currency and distributed ledger are widely used, any subsequent disintermediation may have an impact on savings or credit evaluation mechanisms
4. The impact of security risks and financial stability
assuming that digital currency is recognized by the public, its use increases significantly and replaces legal currency to a certain extent, negative events such as network attacks on user terminals related to digital currency will lead to currency fluctuations, which will have an impact on the financial order and the real economy
in addition, the virtual currency based on blockchain technology is usually held by a few people at the beginning. For example, the first purchase of bitcoin in May 2010 was $25 pizza purchased by 10000 BTC, and the price of each bitcoin rose to $1200 in more than three years by the end of 2013
{rrrrrrr}
extended materials
Amazon will launch digital currency project in Mexico. Amazon is recruiting software development managers for digital and emerging payments (DEP) to develop new payment procts that will enable customers to convert cash into digital currency
the digital and emerging payments sector intends to launch the proct in Mexico first. The follow-up will be extended to Brazil and India. It is reported that the digital currency project will completely focus on payment services in emerging markets
digital currency is another form of existence and circulation of fiat money, which exists in the form of numbers relative to the current circulation of banknotes and coins. It is legal digital currency in essence. But in the long run, based on a statement issued by the central bank in the public media, through observation, the risks in the new digital currency field of cryptocurrency represented by bitcoin have been greatly reced and mitigated
at present, there are many places in China, including Shenzhen, Beijing, Hangzhou and so on. The government wants to seize the opportunity in the new field of blockchain. For example, Hangzhou announced to launch a 10 billion blockchain fund. This shows that the development of blockchain technology is basically recognized by the government. Whether a new technology can be finally transformed and successfully implemented. In fact, we need to refer to many complex factors, and the key point is whether we can find the appropriate application scenarios and have a strong technical concept.
compared with the current Linux based distributions, there are far more popular ones on the market, and there will certainly be many Ethereum optimized public chains in the future, but why Ethereum
according to the current information of Xiaobian, etherfog integrates additional storage and computing capabilities. And storage and computing are the basic resources that can be foreseen to be used in high frequency, which brings more extensive applicability to ether fog. In the von Neumann structure computer, memory and arithmetic unit are essential, and now the application needs to consume a lot of storage and computing resources to provide services, which makes the addition of powerful storage and computing capacity is even a very necessary condition to become a qualified world computer
we can imagine that in the near future, developing decentralized applications (DAPP) and providing corresponding network services based on ethereumfog will be as convenient as using Alibaba cloud's ECs, Amazon's AWS and Microsoft's azure, and more project parties and developers can migrate to ether fog with lower barriers, Enjoy the new world brought by the truly decentralized distributed fog computing and blockchain value Internet
putting forward a problem correctly is often equal to solving more than half of the problem. At present, etheric fog not only raises the problem correctly, but also solves it in practice. Nowadays, such as status, mixin, beechat and kcash are approaching ordinary users with good user experience. The world of blockchain value Internet is no longer far away from ordinary people. We can hope that in the near future, Ethereum fog in Ethereum world may provide basic services for many dapps like Android in Linux ecosystem. This is the real value realization of ETF.
