That virtual currency can be bought
virtual currency is a currency that can buy goods and services in a specific community in a virtual space. It has the monetary function of medium of exchange and unit of account
virtual currency can be roughly divided into three categories
the first category
has nothing to do with real currency, and can only be used in a closed virtual environment, usually online games, such as world of Warcraft
the second type of one-way exchange can only be used in a virtual environment, and sometimes physical goods and services can be purchased, such as frequent flyer award program, microsoft points, Nintendo points, Facebook credits and Amazon coin
the third type of two-way exchange, which has a buying price and a selling price, is the same as "real" currency, including those issued by issuers, such as second life Linden coin, two-way exchangeable game currency, etc., as well as decentralized cryptocurrencies, such as bitcoin, Leyte coin, Ethereum, etc; Virtual currency & quot; But cryptocurrency is only one of the subcategories of virtual currency.
advantages
complete decentralization, without issuing institutions, it is impossible to manipulate the number of issues. Its distribution and circulation are realized through open-source P2P algorithm
anonymity, tax exemption and supervision free
robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally. Bitcoin price may fluctuate and collapse, and many governments may declare it illegal, but bitcoin and its huge P2P network will not disappear
cross border. Cross border remittance will go through layers of exchange control agencies, and the transaction records will be recorded by many parties. But if you trade with bitcoin, enter the digital address directly, click the mouse and wait for the P2P network to confirm the transaction, a lot of money will pass. It does not go through any regulatory agencies and will not leave any cross-border transaction records
it is difficult for the cat to survive. Because bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile, and create a new P2P currency. But these counterfeit currencies are fragile and vulnerable to 51% attacks. Any indivial or organization, as long as it controls 51% of the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency. Many Shanzhai coins die in this link. The bitcoin network is robust enough. If you want to control 51% of the computing power of the bitcoin network, the number of CPUs / GPUs required will be astronomical.
there is no release at present, just internal testing
even after the issue, there is no saying of buying, because the essence is cash.
Background: the financial application of blockchain technology brings high investment value
2018 China international big data instry Expo opened in Guiyang City, Guizhou Province on the 26th. At the meeting, it was pointed out that China will vigorously develop the digital economy in the future, deeply implement the action plan for the development of big data and cloud computing, and deeply study blockchain technology and application. Especially in the field of finance, the landing application has become the focus of the scientific and financial circles
1. The value source of blockchain is that it can perfectly solve the pain points of the current financial instry:
in today's asset securitization, insurance, supply chain finance, commodity trading, asset custody and other financial scenarios, e to many participants, high cost of credit evaluation, low settlement efficiency of intermediary institutions and other reasons, Traditional financial service methods are difficult to effectively solve the long-standing core pain points in the instry, such as information asymmetry, complex and rendant processes, and high information verification cost
2. Why can blockchain solve the above pain points:
blockchain technology integrates many basic technologies, such as distributed accounting, tamper proof, built-in contract, etc., and constructs a trust building mechanism with lower cost. The financial application based on blockchain technology can realize the ability of all market participants to obtain all transaction information and asset ownership records in the market without discrimination, and effectively solve the problem of information asymmetry; Smart contract embedding reces the error rate of payment and settlement, simplifies the process and improves efficiency; At the same time, based on transparent information and brand-new trust mechanism, there is no need to spend manpower, material resources and financial resources to confirm information among participants, which will greatly rece the trust cost between institutions, and then rece the price of financial services and transaction costs
3. The application of blockchain technology in the financial field mainly includes the following aspects:
① digital currency
among which bitcoin is the most famous. On the basis of bitcoin, a large number of other types of decentralized digital currencies have been derived. Such as: the heyday of bits
Compared with the traditional payment system, blockchain payment can directly carry out end-to-end payment for both parties without the help of the banking system, which can greatly improve the speed and rece the cost③ digital bills
④ bank credit management: the advantage of blockchain is that it can rely on program algorithm to automatically record credit related information and store it on every computer in the blockchain network, with transparent information, tamper proof and low cost
The major financial institutions and exchanges in Europe and the United States have explored the application research of building the next generation of financial asset trading platform based on blockchain technology4. The development prospect of blockchain. The future development of blockchain technology will have the most vitality with alliance chain as the entry point, and will have a significant effect and far-reaching impact on the transformation of traditional financial instry pain points
in response to the good investment prospects of blockchain, domestic enterprises such as Alibaba, Jingdong and Netcom have entered the market. The application of financial scenarios based on blockchain technology not only brings us security and convenience, but also provides us with broader investment space. The rise and price surge of digital currency represented by bitcoin (bitcoin was about RMB 20 cents when it was first listed in 2009, and its current price is about US $7300!) It's the best proof that people with a keen sense of smell have made a lot of money from it
Abstract: This is an encrypted digital currency based on the bitcoin developed by Nakamoto Tsung, which improves and adds many new functions, such as the double-layer reward system network, also known as the main node network. It also includes anonymous payment to improve the interchangeability (bitage) and real-time payment function docking to realize real-time transaction confirmation without relying on the authority of the center (P2P mall) In 2009, Nakamoto put forward the concept of bitcoin. Since then, bitcoin has spread rapidly in mainstream applications and commercial uses, becoming the first digital currency to attract a large number of users, which is a milestone in the history of digital currency. However, from the perspective of completing the transaction, we can find an important problem, that is, it takes too long for bitcoin block to confirm the transaction. Traditional payment companies have found a solution to enable the buyer and the seller to realize zero confirmation of bitcoin transaction, but this solution usually requires a trusted third party to complete the transaction outside the agreementbitcoin provides pseudonym transaction, realizes the one-to-one transaction relationship between sender and receiver, and can always record the transactions occurred in the whole network. Bitcoin only provides low-level privacy protection, which is well known in academia. Despite this deficiency, many people still believe in the transfer history recorded by blockchain
based on Nakamoto's achievements, bitshengshi is an encrypted digital currency with the purpose of protecting privacy. We have made a series of improvements on the basis of the concept of bitcoin, resulting in a decentralized cryptocurrency with good anonymity. It supports tamper proof real-time transactions, and has a point-to-point sub network that can provide service reward system for bitsheng network
2. Master node network
the whole node is the server running on the P2P network, so that small nodes can use them to accept the dynamic changes from the whole network. These all nodes need significant traffic and other resources that consume a lot of cost. Therefore, it will be observed that the number of these nodes on the bitcoin network presents a steady downward trend over a period of time, so that the block broadcast time needs an additional 40 seconds. In order to solve this problem, many solutions have been put forward, such as the introction of Microsoft Research's new incentive plan and bitnodes incentive plan

e to the decentralized programming of bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes.
