Future digital currency blockchain Technology
in the Internet era, there is a database behind every system. This database can be regarded as a large account book. In the past, the person who maintained the system was responsible for managing the database and recording the user's behavior, that is, bookkeeping. However, the blockchain is "decentralized", which allows every member of the system to participate in it, not only everyone bookkeeping, but also through links, Everyone can have a complete account book
"blockchain is essentially a collective recording mode. What's special is that it adopts a set of techniques in an ingenious way to realize the authenticity and credibility of the recorded results, which is difficult to destroy and tamper with. " Zhang Xiaorong said, "first, everyone has the right to record and authenticate with each other to distinguish the true from the false, which is called consensus mechanism; Second, no one can tamper with the records, because there are cryptographic signatures; Third, everyone has a , so even if some account books are damaged, the whole will not be affected. This is called distributed storage. The information recorded in this way is presented in block mode according to the time chain, so it is called blockchain. "
various cryptocurrencies represented by bitcoin are originally an application of blockchain technology, which can be described as blockchain version 1.0. However, around 2014, the instry began to realize the important value of blockchain technology. Blockchain graally separated from digital currency and applied to various economic and social fields other than digital currency
it has broad application prospects
blockchain technology is considered as a disruptive innovation after steam engine, electric power and Internet. If the steam engine and electricity liberate the proctivity, and the Internet has changed the way of information transmission, the blockchain, as a machine for building trust, may change the way of value transmission
for example, in the financial field, the cost of reconciliation, clearing and settlement between financial institutions, especially cross-border financial institutions, has always been very high, and there are complex manual processes. The application of blockchain technology can help rece the cost of reconciliation and dispute resolution between financial institutions, and significantly improve the processing speed and efficiency of payment business, It also makes small cross-border payments possible. In December 2017, China Merchants Bank completed the RMB position transfer business from Hongkong Wing Lung Bank to Shenzhen Branch of Wing Lung Bank. This is the world's first interbank cross-border RMB clearing business based on blockchain technology
in addition, according to the white paper 2016 on China's blockchain technology and application development issued by the Ministry of instry and information technology of China, the application of blockchain has been extended to medical and health, ecation, charity, social management and other fields. Taking the cultural instry as an example, the low cost of reproction, the high cost of safeguarding rights, and the difficulty of providing evidence make the protection of intellectual property rights a pain point for the instry. With blockchain, the proction, dissemination and transaction records of cultural procts are true, transparent and reliable, and the problem can be solved
Zhang Xiaorong said that blockchain technology has solved two major problems in the era of Digital Economy: one is the visible flow direction, and the other is zero trust cost. In the past, the circulation of physical paper money was invisible, but the flow of all digital assets had a "chain" to check. Yang Yanchao, a researcher at the intellectual property center of the Chinese Academy of Social Sciences, also believes that the biggest advantage of blockchain is that it has truly completed the credit construction in an anonymous society, bringing new opportunities to many fields, thus making various innovative applications possible
there is a long way to go in the future development
in terms of technology promotion, there is no big barrier to blockchain, which has been confirmed in the global practice of bitcoin, and its main resistance comes from the obstacles in concept and implementation
"on the one hand, the society may be very concerned about the" naked "state in the blockchain. Blockchain has built a "Skynet" for the commercial society. The company's economic activities are all recorded, so there is no secret to speak of. In this way, some business strategies may not be implemented under the blockchain. "
"on the other hand, the current legal system lags behind the development of information technology, so how to put the emerging blockchain technology under the legal supervision needs to be studied." Duan Yongchao said
the core of blockchain is decentralization, which will have an impact on the long-standing central management model. In addition to the law, how to establish a regulatory environment that can promote the application of blockchain technology, so that the technology can benefit the society and not be used to do evil, is also an urgent problem to be solved.
Here you need to understand the correct digital currency issuance process, which is roughly divided into eight steps:
the first step is to build a digital token system
this is very simple. The code of bitcoin is public, and it is a kind of counterfeit currency after simple change; Ethereum's technology is open source. You can find a program to issue a coin on Ethereum's public chain. Now most of the counterfeit coins are on the public chain of Ethereum, and the distribution of tokens is also directly in Ethereum's wallet, which is very convenient
Step 2: find someone to endorse
if the project can be implemented, you may find a real influential tycoon, and by the way, you can take an angel wheel to do marketing. If the project is air money, it may be a grassroots tycoon. In any case, now that the coin circle is just emerging, many "tycoons" are actually grassroots. If you can't, you can send candy directly by virus marketing
Step 3: prepare a white paper
this has to be written on the top. For high-quality coin, vision, code, planning, team and so on need to be well written, which takes a lot of time. But for air coin, it's OK to find a professional agent directly, and it can be written in one day
The fourth step is to promote marketingfind all kinds of coin circle media to advertise, or get a virus activity to invite candy delivery, and brush the popularity
Step 5: love Western Europewith a certain popularity, he began to love Western Europe directly. Good projects are very simple, and they are often looted in a small scale. It doesn't matter if the air currency can't attract people. It's easy to find the agent investment channel to help you package the project
Step 6: contact the exchange
generally, they try their best to go to a well-known exchange. If there is no angel round, you can only take the money from aisio. It's not good. It's OK to go to an easy exchange
Step 7: public offering
once on the stock exchange, you will have enough confidence to speak. At this time, we can continue another wave of public offering. Anyway, what we give out are tokens, which can also attract more attention from the market
Step 8: go online
once the funds are sufficient and the quality of the project is good, there will be more mainstream exchanges. Once the mainstream exchange is finished, this is a reliable project
if it is normal, through the above eight steps is the use of blockchain technology of digital currency
but more often is the digital currency issued by indivials, belongs to MLM currency, more common in online private placement, such as the task Gang blocked before strong>
in view of the bright future of blockchain, the capital has long been in the lead. According to the data of foresight Instry Research Institute, the scale of global blockchain venture capital has increased from US $2 million in 2012 to US $484 million in 2015, with about 205 venture capital institutions participating in it. The high capital fever can be seen. However, the blockchain instry is still in its infancy, and has not yet formed a unified specification and technical standards. At the same time, it lacks killer applications.
first of all, it can be determined that digital RMB can be exchanged for gold and foreign exchange
Digital RMB is only a payment method of legal tender, which is endorsed by the state. The research and application of legal digital currency is concive to meeting the public's demand for legal currency under the condition of intelligent digital economy, improving the convenience, security and anti-counterfeiting level of retail payment, so as to accelerate the development of China's digital economy. It has all the functions of paper money, including the exchange of gold and foreign exchange strong>
At present, the most successful application of blockchain technology is the digital currency represented by bitcoin, and blockchain also benefits from the deeper development of digital currency
instry insiders said that if a wants to send a bitcoin to B, it first needs to send a transaction request to the blockchain network, provide the addresses of a and B as well as the number of bitcoins sent, and at the same time use the private key to digitally sign the sent information to prove its identity to B. After the information is sent, the miner needs to determine the uniqueness of the transaction, the legitimacy of the address involved in the transaction, the authenticity of the digital signature and the correctness of the number of bitcoins after receiving the information sent by A
after successful verification, the transaction will be added to the block, and each block contains all the transactions in the past ten minutes. Generally speaking, each transaction must be confirmed six times before it can be recognized as a legal transaction on the blockchain. Finally, the block is chained, the transaction is completed, and B receives 1 bitcoin

block chain is a public record of bitcoin transactions in chronological order. The block chain is shared by all bitcoin users. It is used to verify the permanence of bitcoin transactions and prevent double consumption
a block is a record in the block chain, which contains and confirms the transactions to be processed. On average, a new block containing transactions is added to the block chain by mining every 10 minutes.
