VP virtual currency wechat group
Contracts, transactions and their records are an important part of our social, economic, legal and political systems. They protect our assets and define the boundaries of the organization. They formed and verified our personal identity and various historical events. They manage a series of activities between the state, organizations, communities and indivials. They direct all management and social activities. But these key tools and the bureaucracy that manages them have not kept pace with the digital transformation of the economy. It's like F1 racing in a big jam. In a digital world, our way of supervision and administrative control must be changed
blockchain has the potential to solve this problem. As the core supporting technology of bitcoin and other virtual currencies, blockchain is an open, distributed ledger, which can effectively record the transaction records between the two parties, and can be verified and permanently saved. The ledger itself can be programmed to automatically trigger transaction completion
five basic principles of blockchain technology
1. Distributed database
each party on the blockchain can obtain all data and complete historical records. No one can control data or information. Each party can directly verify the records of all parties to the transaction without mediation
2. Point to point communication
each independent point can communicate directly without a central node. Each node can store information and transfer all information to all other nodes
3. Limited transparency
users who have access to the system can see every transaction and its value. Each node or user on the blockchain has a unique address composed of letters and numbers, which can be used as the identity of the user. Users can choose to remain anonymous or disclose their identity to others. Transactions occur between addresses on the blockchain
4. Records cannot be changed
once the transaction results enter the database, the account information will be updated accordingly, and the records cannot be changed, because these information are related to all previous transaction records (this is the source of the term "chain"). Various calculation algorithms and methods are used to ensure that the records in the database are permanent, sorted in chronological order, and can be seen by all other people in the network
5. Computational logic
the digital nature of the ledger means that blockchain transactions can be connected with computational logic, and can actually be realized by programming. All users can set algorithms and rules, so that transactions can be automatically triggered between nodes
with blockchain technology, we can imagine that in a new world, contracts are stored in a transparent shared database in the form of digital programming, and will not be deleted, tampered with or revised. In such a world, every protocol, every process, every task and every payment will have a digital record and a digital signature that can be identified, verified, stored and shared. Intermediaries such as lawyers, brokers and bankers are no longer necessary. Indivials, organizations, machines and algorithms can freely interact and trade with each other without friction. This is the infinite potential of blockchain
in fact, almost everyone has heard that blockchain will bring revolutionary impact on enterprises and redefine enterprises and economy. Although we are enthusiastic about the potential of blockchain, we are also worried about exaggeration. It's not just security issues (such as the collapse of a bitcoin exchange in 2014 and the recent hacker attacks) that worry us. The experience of research on technological innovation tells us that if there is a blockchain revolution in the future, there will be many obstacles - technological, governance, organizational and social obstacles. It is likely to lead to a big mistake to rashly apply blockchain technology innovation before we really understand blockchain thoroughly
we believe that it will take many years for blockchain to bring real changes to enterprises and governments. Because blockchain is not a "disruptive" technology, disruptive technology can impact the traditional business model with low-cost solutions, and can quickly replace traditional enterprises. We believe that blockchain is a basic technology: it has the potential to create a new foundation for our economic and social system. But its impact is very extensive, and it will take decades for blockchain to penetrate into economic and social infrastructure. The process of blockchain popularization will be graal, and this process and its strategic significance will be the focus of this paper
technology adoption mode
before discussing blockchain strategy and investment, let's recall the technology adoption process we know below, especially the adoption process of other basic technologies. One of the most relevant examples is the distributed computer network technology, that is, the adoption of TCP / IP protocol, which has laid the foundation for the development of the Internet
TCP / IP first appeared in 1972 and has been widely concerned in an independent application scenario: it is the basis for sending e-mail between researchers on ARPANET, which is the predecessor of the commercial Internet developed by the U.S. Department of defense. Before TCP / IP, the communication system architecture was built on the basis of "circuit switching". The connection between two parties or two machines must be preset and maintained through the switch. In order to ensure that any two nodes can communicate, telecom service providers and equipment manufacturers have invested billions of dollars in dedicated lines
TCP / IP has completely changed the above mode. The new protocol digitizes the information and decomposes it into many small packets, each packet contains address information. Once these packets are released into the network, they can reach the receiver by any route. The data sending point and receiving point in the network can decompose the data packets, combine the data packets again, and interpret the data. There is no need for dedicated lines or large-scale infrastructure. TCP / IP creates an open and shared public network, which has no central organization or main body responsible for maintenance and update
traditional telecom enterprises and related enterprises are suspicious of TCP / IP. Rarely imagine that data, information, audio and video can be established under the new system, and rarely imagine that the related system will be very safe and develop rapidly. However, from the late 1980s to the 1990s, more and more enterprises, such as sun, next, HP and silicon graphics, used TCP / IP to develop their internal LAN. By doing so, they have developed technologies that go beyond e-mail and graally replace traditional LAN technologies and standards. With the adoption of these newly developed technologies and tools, the proction efficiency of enterprises has been greatly improved< In the mid-1990s, the emergence of the world wide web made TCP / IP widely used. The newly founded high-tech enterprises began to provide relevant "tools" - hardware, software and related services, which are necessary for connecting with the current open network and exchanging information. Netscape has commercialized browsers, web servers and other tools and components. Sun company promotes the development of Java. With the exponential growth of information on the Internet, Infoseek, excite, Altavista, and Yahoo are leading users to use TCP / IP technology
once this basic infrastructure is widely accepted, the new generation of enterprises can seize the opportunity brought by low-cost Internet access to create more Internet services, which in turn helps to replace the original business model. CNET has moved news online. Amazon sells more books than any physical bookstore. Priceline and Expedia make it easier to buy tickets, and the whole purchase process is more transparent. These new enterprises expand their business at a very low cost, making traditional enterprises such as newspapers and physical retail stores feel unprecedented pressure
relying on the widespread Internet, enterprises can create novel and revolutionary applications, which are enough to fundamentally change the traditional business model and create value. These enterprises are built on the new P2P architecture, and generate value by coordinating the users of the distributed network. Imagine how eBay has changed the online retail business through auction mode, Napster has changed the music instry, Skype has changed the telecommunications instry, and Google has changed the Internet search by using the links formed by users to provide more accurate search results
many enterprises have used blockchain to track goods in the supply chain. Finally, it took more than 30 years for TCP / IP to become widely accepted - used alone, locally applied, replaced and transformed - and reshape our economy. Today, more than half of the world's most valuable listed companies are Internet driven, platform based business models. The foundation of our economy has fundamentally changed. Physical assets and proprietary intellectual property rights are no longer the guarantee of competitive advantage; Enterprises that lead economic development can play a key role, especially in organizing, influencing and coordinating a wide range of community networks, users and organizations
new system
blockchain, the P2P network at the top of the Internet, came into people's view as the core foundation of bitcoin in October 2008. Bitcoin is a virtual monetary system, which does not issue currency through the central authority, transfers ownership and confirms transactions. Bitcoin is the first practical application of blockchain technology
the similarities between blockchain and TCP / IP are obvious. Just as email allows people to exchange information, bitcoin allows people to trade with each other. The development and maintenance of blockchain is open, distributed and shared - just like TCP / IP. There's a group of volunteers around the world maintaining their core software. Like email, bitcoin has received enthusiastic support from people at the beginning, but only a relatively small number of people
TCP / IP greatly reces the cost of interconnection, thus creating new value for economic development. Similarly, blockchain can significantly rece transaction costs. Blockchain has the potential to become all transaction recording systems. If this becomes a reality, new enterprises based on blockchain technology will influence and control emerging instries, and the economy will experience fundamental changes again
let's first look at how enterprises operate. Recording transactions is the core work that every enterprise must do. These records track past activities and achievements and provide guidance for the future. They can not only let people understand how the enterprise operates internally, but also let people know how to keep in touch with the outside world. Every enterprise or organization has its own records, and these records are private and confidential. Many enterprises do not have a general ledger record of all activities of the enterprise; On the contrary, all records are scattered in various branches or departments within the enterprise. The problem is that it takes a long time to coordinate transactions between indivials and private ledgers
virtual currency is still a chaotic instry, and MLM is very popular in China. However, there are also some applied digital currencies, such as the tokens of Euroland crowdfunding and crowdfunding projects.
virtual currency is the proct of the Internet, which refers to non real currency. In the case of the connection between virtual and reality, virtual currency has its real value
the well-known virtual currencies are familiar to everyone, such as the network currency of the network company, the Q currency of Tencent company, the Q point, the voucher of Shanda company, and the micro currency launched by Sina; In recent years, the popular digital currencies include bitcoin, Wright coin, infinite coin, quark coin, zeta coin, barbecue coin, penny coin, invisible gold bar, red coin, prime currency, etc. at present, there are more than 100 kinds of digital virtual currencies issued all over the world
Second, the classification of virtual currency
the first category is the familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money and so on, and uses these to buy materials and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency
the second category is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third category is virtual currency on the Internet, such as bitcoin (BTC), lightmoney (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency< Third, the development of virtual currency has just begun in the long history of mankind, and the decentralized cryptography currency bitcoin is the most famous. Bitcoin, as a concept, came into being in 2008 and was put forward by a mysterious expert with the pseudonym of "Nakamoto Tsung". At that time, bitcoin was worthless, but there were always player transactions, which made it grow slowly from 2009 to 2012, especially in the second half of 2012, showing explosive growth, with the highest value of 8000 yuan per currency. This makes many players who are not bitcoin come in and regard it as a way of investment and financial management. From 2009 to now, bitcoin has been recognized by one country, and now more than 100 countries are using and circulating bitcoin
since 2015, the application process of cryptocurrency has begun to accelerate, and more and more cryptocurrency has graally entered the life of ordinary people, and is increasingly widely used in the world. Virtual currency can not only be used for financial management, but also can be used to buy goods. In the future, it will circulate in the world like traditional currency
all kinds of signs show that virtual currency will replace traditional currency.

cryptocurrency other than bitcoin
cryptocurrency other than bitcoin, also known as Shanzhai currency and competitive currency (English: altcoin), part of which is generated by referring to bitcoin ideas, principles and source code, Virtual currency similar to bitcoin has more than 800 cryptocurrencies in circulation
from February to April 2017, the proportion of Shanzhai currency in the total cryptocurrency market value increased from 15% to nearly 40%
because bitcoin itself does not have an authoritative issuing institution and state power to maintain its authority and uniqueness, bitcoin and its imitators can only live on an equal footing, although it is the earliest virtual currency, the most well-known and familiar one, and has the largest user network community with strong network effect, Most of the time, it is also the password currency with the highest market value, but it does not have the absolute exclusive status[ 1]
Fuyuan coin, formerly known as fortune coin, or FTC for short, is a new type of decentralized digital encryption virtual currency, which is operated as a whole by the China US Association for the promotion of encrypted digital currency. Fuyuan coin will be used in all enterprises of the global jewelry Association in the future, mainly through the digital currency into points, to create a decentralized business circle, to promote business cooperation and expand business scope. At present, some large financial, trade, energy and other traditional enterprises at home and abroad are trying to develop this new business model (www.saidi.com)
there are two kinds of showdown accessories: ordinary and special. The ordinary one is to improve players' basic attribute ability, while the special one can provide some special abilities. The proction of ordinary jewelry can be made as long as the ore is mined, while the proction of special jewelry needs not only ore, but also ancient stone, which can be dropped by boss. Jewelry can be made in the smelter by Gleason or in ark by Leite.

But I don't suggest you buy AMD. Second level cache now amd has no advantage< The main board Gigabyte ga-ep43-ds3l 620 yuan Gigabyte version is relatively stable. Now all the four core machines in Internet cafes are equipped with Gigabyte version. Do you need me to explain why?
seven rainbow video card igome 9600gt-gd3 up flame ares 5F 512M R10 640 yuan seven rainbow is the most outstanding OEM manufacturer in China for the time being. The most important thing is that compared with Yingchi in terms of price, IFLYTEK and other aspects have more advantages, but in the same frequency, the effect of the graphics card of each medium block manufacturer is almost the same. It's cheaper there, of course. Onda sells the motherboard crazily, not the graphics card, so don't make a mistake. Moreover, Onda is mainly aimed at the middle and lower end of the player market. If the graphics card is used for a long time, the heat sink will fall off. Don't buy it<
