Blockchain configuration requirements
first, how to make a fixed investment
1, why should we make a fixed investment? Because no one can determine where the bottom is, blockchain is high-risk and high-yield, and only through fixed investment can the risk be reced
2. What kind of assets are worth fixed investment
one is hard currency bitcoin, the other is widely used ether currency, and the third is a new currency with good credit endorsement. Team background must be strong
3. When is the fixed time
you can make a fixed investment every week, every two weeks and every month. If you even have trouble making a fixed investment every month, I suggest you stop making money and go to sleep
4, how much capital will be invested
the suggestion of blockchain Dashen laomao is that within the range of 10% ~ 30% of your disposable assets, I will calculate it by 20%. For example, if you have a disposable asset of 100000 yuan, you can arrange 3000 yuan for investment from your income every month. If your fixed investment period is two years, then your total investable capital is 100000 * 20% + 3000 * 24 = 92000 yuan. Divided by 24 months, you can invest 3833 yuan per month and 958 yuan per week< Second, diversify investment
after listening to the sharing of laomao and other gods, the suggestions for blockchain assets are as follows: 50% bitcoin + 15% eth + 15% your favorite small currency + 20% crowdfunding new currency.
the mainstream currency is low-risk and low-income. Small currency is a hobby, and the potential of new currency is huge. Its income will one day become your main asset, such as 1 yuan crowdfunding ant stocks, up to 1400 + yuan. Strong background of the team + pragmatic landing, as long as given the time, in this circle to return a hundred times a thousand times is very normal! Among them, blockchain + finance is the easiest scene to implement, so the projects of asset chain have always been popular
we recommend a popular project, sealchain financial public chain, which directly covers seven financial application scenarios, including Inclusive Finance, supply chain finance, ABS, insurance, equity, corporate bonds and intelligent investment advisory. It is expected to become a black horse in the money circle from 2019 to 2021! And in 2019, the exchange price is only 1 yuan!
according to Xiao Wang, the concept of blockchain as a service (baas) is mainly proposed by Microsoft and IBM. To put it bluntly, it is actually a new type of cloud service, a cloud service combined with blockchain technology. For example, Microsoft's azure cloud computing platform and IBM's bluemix garage cloud platform all provide blockchain as a service baas
blockchain as a service (baas) is a space created by enterprises such as Microsoft and IBM from their own cloud service network to run a blockchain node. Compared with ordinary nodes and exchange nodes, the main purpose of baas nodes is to quickly establish the development environment they need, and provide a series of operation services based on blockchain, such as search query, transaction submission, data analysis, etc. these services can be centralized or decentralized to help developers verify their concepts and models faster. The service of baas node is reflected in: it is more instrumental and easy to create, deploy, run and monitor blockchain.
If bitcoin represents blockchain version 1.0, it proves to the world that digital currency can be realized. Then Ethereum represents blockchain version 2.0, which lets you know more about the play of blockchain, decentralized applications and smart contracts. In 2018, blockchain will enter the stage of 3.0, application and scenario landing will be the core of blockchain, and blockchain based applications in various instries will spring up, which will be the early dividend period of the last stage of blockchain development. The demand for talents driven by the application of blockchain technology has become increasingly large. Blockchain technical talents have become the new professional talents, which are highly competitive, and also have enviable high salaries
whether to form a meaningful large-scale consensus: one of the outstanding advantages of blockchain is that it can effectively form a large-scale consensus by opening account books and notifying the whole network. At present, there is no need to form a network wide consensus for many projects. Some projects are just for crowdfunding and token issuance. The blockchain consensus of projects is meaningless. Does this model have network effect: network effect means that a project will become more and more valuable with more and more users of the project, because the value of the project is not in the users themselves, but in the connection network between users. Bitcoin is a typical example. The more user nodes there are, the more links between nodes will grow exponentially, and the whole ecosystem of bitcoin will be more valuable
of course, in addition to these points, there are many basic principles to judge the project, such as effective incentive mechanism, strong team, project solving pain points, and so on
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< Second, openness:
the foundation of blockchain technology is open source. In addition to the private information of all parties to the transaction is encrypted, the data of blockchain is open to all. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent< Third, 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< Fourth, security:
as long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily controlled 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 information transmission can be carried out anonymously
Digital China is the first major development strategy explicitly put forward in the report of the 19th National Congress of the Communist Party of China. The application of digital technology represented by cloud computing, big data and mobile Internet is no longer limited to the economic field, but widely penetrated into all aspects of public services, social development and people's life, which requires macro coordination, overall control and integrated development
with the deepening of a new round of scientific and technological revolution and instrial change, the tide of digital economy in the world is unstoppable. The development of digital economy has become a global consensus, known as the key to the fourth instrial revolution
adhering to the connotation of the University of nice's world inclusive humanistic spirit, always embracing change, standing up to the tide, conforming to the development trend of the digital economy era, and integrating the essence of Chinese and Western cultural thinking, the University of nice's doctor of blockchain and digital economy management (DDE) came into being
based on this, we can enable the managers of digital economy instry to have global vision and global integration thinking, integrate knowledge, operate digital economy intelligently, promote the sustainable development of the instry, and contribute to the community of human destiny. Therefore, DDE project will cooperate with colleagues in the field of digital economy

1. Most people don't know what a blockchain is
compared with traditional stocks, real estate, bonds, gold, etc., blockchain assets are a very abstract and virtual form of assets. Blockchain assets represented by bitcoin are a very specialized computer language and program running mode, There is no credit endorsement from any country behind it, nor does any enterprise give it securitization income, which completely depends on the mutual consensus trust between strangers. In this case, although the operation logic of decentralization has been completed, its experiment is only in the initial stage and development stage, and participating in relevant investment is actually a kind of brave adventurer behavior
2. The price of blockchain assets fluctuates violently
because there is not much support from the use level of entities, many blockchain projects are completely dependent on community operation and market speculation, so it is difficult for investors to hold blockchain assets from the perspective of value investment, which leads to frequent capital flow, and the situation of price fluctuations has become a normal. A blockchain related token can soar by 500% in a day, or fall by 90% in a few hours. This kind of drastic price fluctuation is not affordable to ordinary investors
3. The uncertainty of national policies is too great
as an underlying technology, blockchain has basically accepted its value all over the world. However, as the "companion proct" of blockchain, there are still great disputes on national policies, and with the continuous increase of digital currency trading volume, the impact on the global financial market is also increasing. At present, the daily trading volume of the whole digital currency field exceeds US $60 billion, which is comparable to the trading volume of China's Shanghai and Shenzhen stock exchanges, or the average daily trading volume of the New York Stock Exchange. It is impossible to continue to operate outside the supervision. There is a very large regulatory game cycle, and the policies of various countries in this regard may be introced one after another, The impact on the market cannot be ignored
4. All kinds of blockchain projects are good and bad
blockchain technology is originally a very basic architecture technology. At present, e to the global pursuit of funds, many project parties who have nothing to do with blockchain begin to use the concept of blockchain to design procts, And can complete the writing of the white paper of blockchain in a very short time, and then raise market funds. In this case, the technical threshold of the whole blockchain has been lowered. Many companies without the strength and willingness of blockchain development have developed the concept of blockchain purely to obtain financial support, resulting in the flooding of projects. The gap between projects is widening, but ordinary investors are difficult to identify and easy to fall into the trap
5. Currency speculation is not equal to blockchain investment
at present, there are many views that blockchain and digital currency are a whole. You can't develop blockchain technology while suppressing digital currency. I agree with this logic, but currency speculation is not the same as blockchain investment in the real sense. The thing with real investment value must be the thing with scarce supply. If any digital currency is issued, it can represent the application value of the blockchain and bring some innovation to the society. Then any blockchain technology team that can issue digital currency can issue dozens of digital currencies and change its name in a very short time. Therefore, digital currency itself has little logical relationship with blockchain assets. Blockchain projects must be a market with obvious scarcity, but digital currency does not have great scarcity. This is like saying that any Internet company can develop a chat software similar to wechat, but the chat software itself does not have much value. The real value lies in how many people participate in the chat software. Digital money is just a chat software. The current situation is that everyone is frying the software, and few people are concerned about what is on the software. p>
6. Short term overheating, easy to be used by lawless elements
the particularity of the blockchain instry is that many of the ecology has become very financial, in the whole process of operation, capital will be very concentrated, and most of the links are related to capital. From raising funds by ICO to sending tokens to investors, to online trading of exchanges, and trading of tokens by users in exchanges, the whole process is almost full of financialization. If the practitioners are not professional enough, have no self-discipline ability, and lack of supervision, then every link may be used by criminals to manipulate the market, Obtain all kinds of illegal income
In order to catch up with the next round of financial technology and digital revolution, Japan holds a very open attitude towards bitcoin and other transactions. Digital currency transactions denominated in Japanese yen occupy half of the whole legal currency trading area in the world, Japan hopes to use digital currency to revive its financial competitiveness. The United States hopes to use mainstream financial markets, such as futures and options derivatives market, to tame bitcoin and make it another powerful tool for us dollar hegemony. And China is also trying to promote sovereign cryptocurrency, one of the important purposes is to promote the internationalization of RMB. The field of digital currency and blockchain assets is likely to become the next big country's game and contention point, which will virtually increase the systematic risk to investors. It's hard to know what unexpected policies appear behind this big country's game and what impact they will bring to the whole market8. The threat of quantum computer
blockchain generates a set of self-motivated system to ensure that it can run on its own under decentralized conditions. Most of them use asymmetric encryption, and use the corresponding public key to verify the transactions signed by the private key, so as to ensure that bitcoin and other blockchain assets can only be used by legitimate owners. But quantum computer can solve the problem of asymmetric encryption. Quantum computer can calculate the private key from the public key in a few minutes. After knowing all the private keys, people with quantum computer can spend bitcoin and other digital currency at will. Of course, when the quantum computer will come out is also a problem. The digital currency protocol is constantly adding new encryption standards, but the potential threat brought by the quantum computer has to attract the attention of investors
9. There is a possibility of a big reversal in the supply and demand level
the market value of the blockchain token market has hovered around us $trillion. Although OTC funds are still pouring in, the stability and growth rate of the capital inflow are questionable. The supply of encrypted digital currency is a very embarrassing thing. From the perspective of a single digital currency, the total amount is strictly limited. For example, there are only 21 million bitcoins, but the threshold of issuing encrypted digital currency is getting lower and lower. Anyone and any organization can issue encrypted digital currency anytime and anywhere, and the supply is almost unlimited. On the other hand, the increasing transaction cost is restraining the demand side. At present, investors in the transaction link need to pay the transaction fees in the exchange, and also pay the miners' fees when transferring money. If countries begin to tax digital currency transactions in the future, it means that this market will have to bear more operating costs without generating its own profitability, If coupled with the increasing supply level, the overall market supply and demand expectations may reverse in a moment
10. Lack of legal protection for blockchain assets
it is not uncommon that global digital currency exchanges have been "hacked", and in the process of all kinds of over-the-counter and on-the-spot transactions, fraud also occurs from time to time, and the legal protection for investors is very limited. Especially for domestic investors, once they are stolen or cheated because of trading digital currency, it is almost difficult to recover effectively. Due to the lack of intermediary guarantee from banks and other levels, the security of digital currency is entirely under their own responsibility. Although this is in line with the logic of self preservation of private property, it also brings greater uncertainty to the storage and transaction of digital currency assets. Before there is no complete legal system to protect the rights and interests of personal digital currency assets, the legal security of investment in blockchain related assets is a very serious problem
this kind of stacking design of eth 2.0 is compatible with its fragmentation chain structure. By setting the fixed mortgage number of 32eth compulsorily, the number of nodes in the whole network is relatively large, and the head node with huge mortgage number will not have monopoly accounting control right in a fragmentation chain, Therefore, the degree of decentralization of eth 2.0 mining will be improved to a certain extent
the second difference: principal and income are not one kind of currency, which can not be traded in the early stage
except for ontology, vechain and other al currency structure design projects, generally speaking, stacking mining is "lock what currency, earn what currency", but eth 2.0 locks eth token on the main chain of pow, and the income released is Beth token on the beacon chain. They are essentially two kinds of currency. Because the two chains will not be interconnected soon, the transaction prices of Eth and Beth in the open market will not be exactly the same
at stage 0, which is expected to go online next year, ETH 2.0 will not have the trading function. Even if the verifier (node) withdraws from staging, the principal and income can not be transferred out of the account. Therefore, all the principal and income of the early participating nodes are almost locked. We can only wait for the further development of eth 2.0 to graally realize the account trading function
the third difference: in the early stage, there was no decentralized entrusted mining
the function of "entrustment" can separate the token from the block right carried by the token, and the token holder can entrust the block right to trusted nodes to participate in consensus and win awards on behalf of them, which is also the reason why stacking is widely known by the public and is becoming popular. However, in the first two phases of eth2.0 (phase 0 and phase 1), there is no decentralized entrusted mining, which means that the coin holder can only set up its own node to run, or hand over the coin to the centralized mine pool to mine on behalf of it. However, agent mining is equivalent to transferring the coin to someone else for trusteeship, which has the security risk of capital
secondly, we need to understand the participation conditions of Ethereum staging
the participation threshold of Ethereum staging is not very high. In terms of hardware, the performance of home computer can run a node. Ethereum hopes to encourage more money holders to participate through low threshold, so as to achieve the goal of decentralization as much as possible
because the coin holder is not a professional node operator, it is generally unable to guarantee the 24-hour operation of the node. Therefore, in the design of the economic model, the penalty of Ethereum stacking for the node offline is very small, about 1% for three consecutive days, but the longer the offline time is, the greater the penalty will be, and 50% for 21 days offline
for the participants, 24-hour operation of the node can ensure the maximum revenue. At the same time, it is also necessary to do a good job in node version upgrade, prevention of "double flowers", fault monitoring and disaster prevention. At that time, some node operators will launch professional node operation services
after understanding the above information, let's take a look at the revenue analysis of Ethereum stacking
the annual SEO rate of eth 2.0 changes dynamically with the whole network pledge rate. According to the published rules, the relationship between the annual SEO rate and the whole network pledge rate is 0.5 power. The higher the pledge rate of the whole network, the higher the annual additional issue rate, and the lower the annual return rate of a single node. When the whole network pledge is 10%, the annual yield of the node is 5.72%.
