Blockchain will be issued as currency

1. As a rookie of Bubi blockchain, I'll tell you
Application of blockchain technology in banking

2.1 self regulatory platform

we rarely see a platform that can conct self-regulation without intervention. In all areas similar to the financial instry, central banks and regulators (such as the securities and Exchange Commission) come to set uniform rules and manage them. Blockchain technology makes the system no longer need the supervision from enterprises or government entities, so as to regulate the operation of the system. Blockchain provides a mechanism called "workload proof", which allows each computer node in the system to participate in the approval of each transaction. The system has built-in check and balance mechanism to ensure that no computer in the system can deceive the system. All of these reviews and supervisions are completely automated by the computer. At present, there are many other consensus models that can replace the "workload proof" mechanism, but still retain the core idea that each client or node can manage the system point-to-point. What's more, blockchain makes every element in the system completely transparent. Therefore, for such a large-scale community all over the world, blockchain technology can easily review and manage it - "supervision from the public", thus effectively recing fraud. Imagine how much it can save costs and improve efficiency

2.2 compliance with the law and easy tracking

actors (users) and their behaviors (sending money or assets to others) are recorded on the blockchain. Any transaction between the two parties can be tracked and inquired, and can be proved in court. This is because all transactions need a set of public key / private key to encrypt and decrypt processing and transactions. Once they are added to the blockchain, they are permanent and unchangeable. Any record, once written to the blockchain, cannot be tampered with. Anyone holding assets or digital currency on the blockchain will have their own public key on the blockchain. When a transaction occurs, it needs to be signed by the previous holder who controls these assets using the private key. Blockchain also allows a variety of mechanisms for transactions. For example, it can be set to require two people to jointly sign a transaction. In a system without endorsement of enterprises or government, the legally binding mechanism can greatly enhance the trust factor for the system

2.3 built in business continuity

a global platform can not bear the risk of downtime when concting major transactions. Blockchain, a complete point-to-point network, has many distributed nodes and computer servers to support, which has high reliability. Every node in the system keeps a of the complete blockchain data. This makes the whole network highly fault-tolerant, if any part of a few nodes have problems, it will not affect the other parts of the network continue to operate. This makes it possible to achieve 24 / 7 all-weather operation characteristics like disaster recovery center or database rendancy center without using complex technology

2.4 evolution model without burden

in the system, there are a series of rules and key points to help decide who has the right to approve the transaction and what needs to be reviewed before the transaction is written into the blockchain. Blockchain technology can fork out new versions according to different environments and business model requirements. The new version also needs to conform to the overall concept of blockchain. All these changes must be approved by all members of the system, and everyone can get the same benefits. In addition, these changes will not affect the transactions that have occurred and confirmed on the blockchain. For a system, it has enough robustness and flexibility. People often compare the similarities between the Internet and blockchain, including their growth potential and business prospects. These two systems have very similar characteristics. The Internet does not need or does not have a centralized management department (except for a few for the management of agreed URL and domain name registration), but also has enough rendancy and strong fault tolerance. The Internet has been developing for so many years, from basic text to rich graphics, video, animation, and all this has not affected other existing systems and content. Blockchain has fully proved its function and practicability in bitcoin system. Just as the famous Chinese philosopher Lao Tzu said, "the tree that embraces is born at the end of a tree."; The platform of nine layers starts from the base soil; A journey of a thousand miles begins with a single step. " I think this should be the creed of all the pioneers of blockchain technology

2. We know that the state has always advocated "no money" blockchain. That is to say, don't use the chain&# 8204;&# 8204;&# 8204; Currency, support technology development, do not support issuing currency

of course, the coin here is what we often call token, which originally means token (temporary) in computer identity authentication. With the popularity of blockchain and digital currency, people have a variety of translations for token, including token, integral, certificate, logo, indicator, etc

the understanding of token in the market can be divided into two categories

in the first category, 99% of the people think token means token, because 99.9% of the projects do the same thing. Set up a foundation, build a website, write a white paper, and then go to ICO. Because most of the projects are still in the conceptual stage, token itself has no other meaning except trading, so people call it token, which performs the function of currency to some extent

in the second category, professionals and institutions are more willing to translate token into proof of equity, or token. For example, a person's identity certificate, academic certificate, equity, bonds, points, bills, etc., are authentic and tamperable because of the proof of rights and interests. Every proof of interest becomes more secure and reliable through the protection of cryptography

therefore, blockchain is not only a technology, but also a new mode of proction and organization, even a new thinking

so, the question now is, does the blockchain project have to issue currency

answer: you may not issue currency. Not all blockchain projects need to be issued with currency, and it is not necessarily blockchain projects that issue currency

for example, the alliance chain does not need to issue coins. For example, Tencent's q-coin, in principle, is also a kind of currency, but it is not a blockchain project

therefore, the two are not related, but if they are public chains, they need to issue coins. Why

let's take bitcoin as an example. Bitcoin system as a public chain must rely on the existence of bitcoin. Public chain obtains the stability and non tamperability of its system through the nodes distributed all over the world, and these properties are the basis for the existence of public chain

imagine that if the bitcoin system is unstable or can be easily tampered with, bitcoin will be worthless. These nodes are not set up by one or several companies, otherwise they are equivalent to private chain or alliance chain. These nodes must be built dynamically by many participants. And the existence of these nodes must need some kind of incentive, otherwise why do the builders of these nodes want to participate in your system. And this kind of incentive must be integrated with the blockchain system, and it must be money

then why is it currency, not legal currency, such as RMB, as an incentive

if RMB is used as incentive, because RMB should be stored in the RMB account, and the account itself is centralized, so it's easy to be controlled. Just think about why domestic bitcoin exchanges are so afraid of the central bank, and they are afraid of being weaned. In addition, RMB can't react with smart contracts within the blockchain

the electronic currency issued by the central bank can not be used as the original currency and incentive of a blockchain system. Why

if the central bank or a rich person wants to destroy a project, they just need to take out enough e-money to do enough nodes and attack 51%. Therefore, it is impossible to use the e-money issued by the central bank as the original currency and incentive blockchain system. However, blockchain projects with independent native currency and incentives have no such worries

If a person or organization wants to get enough nodes to carry out 51% attacks, it must first get more than 50% enough coins, and the amount of coins in the market is certain, so before it gets enough coins, the soaring price will make it hard for him to bear

therefore, a public chain project must have money. A public chain project without money is like a castrated person

in addition, only through the token and reasonable stimulation of output, can the proction relationship be changed and the value of blockchain be brought into play. Therefore, the project must have token, which can promote the development of the project faster. Token solves the problem of incentive and consensus, and incentive solves the problem of autonomy. The positive autonomous economic ecosystem and the underlying technology of blockchain are a perfect combination.

Why is the Internet era coming to an end and the blockchain era coming

Once the

blockchain develops, it will burst out more innovation. As the first proct of blockchain, bitcoin has proced many innovations since its birth. For example, small cross-border payment, recording transfer transactions between currencies, recording various stocks, registering housing property rights, recording program codes, etc.

the steam age liberates social proctivity, the electrical age enlivens social cooperation ability, the Internet age connects the world, and the blockchain era will let us truly realize freedom

4. Blockchain technology is the underlying technology of bitcoin, and bitcoin is the first application of blockchain
the transaction information of bitcoin is recorded in a decentralized ledger, which is called blockchain
according to the principle of cryptography, each block is connected in chronological order to form a chain structure, so it is named blockchain.

5. Hehe, I just went there to sign up for a taxi yesterday. When I came back, I saw No.79 passing by our house. Another one was No.51. Look how many routes there are in your house. You can get on the bus and ask the driver where to get off~

6. Bitcoin is a "digital currency" based on blockchain technology. In 2013, the central bank made it clear that bitcoin, as a specific virtual commodity, does not have the same legal status as currency and cannot and should not be used as currency in the market. The reason why bitcoin has become the "accomplice" of hackers this time lies in the characteristics of bitcoin: anonymity and difficulty in supervision

compared with other ways, using bitcoin to remit money is much more "secret". Normal cross-border remittance will go through the examination of exchange control institutions at all levels, and the transaction records will be recorded by banks and other parties. Transactions exceeding a certain amount should be reported to relevant departments to prevent money laundering and other violations. Bitcoin, with the characteristics of globalization, is usually used as a tool for cross-border payment and remittance. As a kind of network encryption virtual currency, bitcoin has the characteristics of decentralization and anonymity,
capital flow is not easy to track, and it is easier to hide identity
wannacry blackmail virus prevention method:
1. Install the latest security patch for the computer. Microsoft has released patch ms17-010 to fix the system vulnerability of "eternal blue" attack. Please install this security patch as soon as possible; For Windows XP, 2003 and other machines that Microsoft no longer provides security updates, we can use 360 "NSA Arsenal immunity tool" to detect whether there are vulnerabilities in the system, and close the ports affected by the vulnerabilities, so as to avoid being infringed by blackmail software and other viruses
2. Close ports 445, 135, 137, 138 and 139, and close network sharing
3. Strengthen the awareness of network security: don't click the unknown link, don't download the unknown file, don't open the unknown email...
4. Back up the important files in your computer to the mobile hard disk and U disk as soon as possible (regularly in the future), and save the disk offline after the backup
5. It is recommended that users who are still using Windows XP and windows 2003 should upgrade to Windows 7 / windows 10 or windows 2008 / 2012 / 2016 as soon as possible.

7. In addition to the postal service and Weizhong, the Bank of Changsha is now cooperating with a public platform called SMIC blockchain, which seems to be a blockchain loan business.

In 1991, the Journal of cryptography published an article by S. Harper and w. stonetta, which discussed the method of adding time stamps to digital documents. In 1992, the same group of people discussed how to increase efficiency. This is the origin of blockchain technology. In 2008, the "blockchain" created by people or groups under the pseudonym of Nakamoto Tsung by bitcoin has a more idealistic color exclusive to the Internet

as one of many solutions of distributed computing, the most significant feature of blockchain compared with other distributed computing is that there is no need for administrators. For this reason, blockchain has paid a huge price in efficiency

Secondly, since digital currency is likely to become an important form of payment for sovereign currency in the future and contribute to the global use of sovereign currency, digital currency and gold are complementary and symbiotic. Blockchain provides a window to observe the real exchange rate and interest rate of sovereign currency. If we need to make the world generally accept the digital currency of sovereign countries, we need to first generally accept the credit currency of sovereign countries. As an ancient and widely accepted credit collateral, gold is obviously an important part of sovereign state reserves. With the impact of digital currency on traditional settlement system, the importance of local currency value will rise

especially with the explosive growth of global negative interest rate bonds, the number of credit collateral that can stably support the value of local currency is decreasing. At present, whether negative interest rate can last is a controversial topic in the academic circle. We tend to think that negative interest rate itself is a short-term phenomenon, and in the long run, it must be settled once and for all. In the process, as a traditional safe haven asset, gold is bound to have more space, and the trinity of gold (credit support), sovereign currency (credit medium) and digital currency (circulation means) will also be the international strategy of sovereign currency

the ideal of blockchain has failed, but the application of blockchain has just begun. The gold instry and gold should play an active role in this wave and contribute to RMB internationalization and instrial upgrading
