Technical scheme of digital currency
Generally speaking, there are not many technologies available for blockchain development. The mainstream development languages are generally divided into the following four types. Different development languages require different timely configuration. You can also visit the blockchain development language selection.
first, go language is selected for development. The high concurrency of go language is very suitable for blockchain development
Secondly, C + + language and C + + technology are mature and fast Thirdly, Java language Four is, node, JSblockchain technology has been questioned by the collapse of the centralized currency exchange, but its potential to solve the trust and centralization problems of the existing information architecture has attracted a lot of attention. Blockchain technology first gained great popularity in the field of bitcoin and digital currency. It uses a single shared ledger to store information. It is no longer to let a single central organization obtain the account book, but to obtain multiple copies of the same distributed account book by different nodes in the peer-to-peer network. Shenzhen yuanzhongrui blockchain technology adopts advanced encryption technology to ensure that any new information in the account book can not be tampered, unless it meets some preset parameters. Moreover, this kind of Ledger has stronger defense against external attacks, such as network attacks, because this decentralized system does not have a single point of failure with high cost of centralized information architecture. At the same time, all trusted nodes can affect any modification of the ledger, provided that they meet the specific preset parameters. These changes will be immediately reflected in the ledger, and all trusted nodes can obtain relevant data to make correct decisions. It can also adjust the design of the distributed ledger, create a hierarchical system within the architecture, and configure appropriate access rights and different levels of authority
blockchain and distributed ledger technology are concive to change the management mode of land registration. At present, the credibility of the real estate market is at the lowest level, which is attributed to the inefficient and opaque property registration system. The system relies on the centralized acquisition of land registration and corresponding property transaction information. Using distributed ledger technology to obtain, manage and modify these information can ensure that the public will not be infringed by land transaction fraud. Similarly, distributed ledger can simplify and integrate cross instry and cross regulatory compliance process, because it contains real-time compliance information needed by government departments, banks, investors and other third parties. By integrating data points of multiple projects and providing feedback on beneficiaries' project participation, we can better track the implementation of social welfare plans
at present, the biggest problems of technology development include: transformation cost of unique data storage system, data reliability verification of network nodes or all levels, privacy and security dimension of decentralized data acquisition, and revision of information technology act. What's important is that blockchain technology will change the way the government interacts with citizens, and this huge change is bound to be resisted by civil servants. These are all possible problems. We should take immediate action to formulate a regulatory framework to guide application development in addition to adopting blockchain technology.
even though many enterprises have invested in the research of blockchain, there are few domestic projects of blockchain, so we should make a certain distinction. At present, there are few enterprises applying blockchain technology to develop digital currency system. For example, the digital currency system scheme developed by Yingtang Zhongchuang has many references. There are many systems developed by Yingtang Zhongchuang. You can have a look at them.
moreover, the development of digital currency is still immature.
The "perfect set of commemorative banknotes" includes ten Hong Kong dollars with a face value of 10 yuan, ten Australian dollars with a face value of 10 yuan, ten new Taiwan dollars with a face value of 100 yuan, and one 50th anniversary banknote with a face value of 50 yuan; A thousand rupiah worth only 0.5 yuan falsely claimed to be worth 300 yuan; The so-called "wrong currency" is actually the fifth set of RMB in the 1999 edition...
according to the Beijing News, in Soho modern city, Dawang Road, Beijing, some cultural companies selling commemorative coins and coins coax the old people to the company by collecting souvenirs for free, and then make them spend tens of thousands of yuan through sales promotion, Buy some cheap commemorative coins and even currency in circulation
Yes, you are right. Even the currency in circulation dares to sell as collection currency. It can be said that the routine of these companies is not clever at all, and even ridiculous, but Rao is so, many old people are cheated. For no other reason, these companies recognize that some old people have money, but they lack knowledge about money
This is obviously against the law. In essence, this is a fraud committed intentionally by taking advantage of the poor discrimination and market information of the elderly, which is suspected to constitute a crime of fraud. According to the criminal law of our country, the crime of fraud refers to the act of defrauding a large amount of public and private property by making up facts or concealing the truth for the purpose of illegal possession. In this regard, it is also necessary to carry out the corresponding special strike, find out and eradicate the relevant instrial chain; And the establishment of effective daily supervision, so that they do not dare to move their minds on the elderly When we were young, our parents were our tutors; Today's elderly parents, in terms of social experience and cognition of new things, often become "children" who need to learn from usin addition, the community, banks and other relevant institutions and departments can also organize some activities to care for the elderly, go deep into the elderly group, and explain the knowledge of prevention of being cheated. In a word, let the old people be "smart" and form a cognitive defense line, so that similar scams will not succeed easily
With the continuous development of Internet and computer technology, whether it is the third-party payment or automatic settlement function, it has brought great convenience to people's life. Recently, another good news is that the era of digital currency is coming. Major banks have successively joined the digital currency pilot work of the central bank. The good news of digital currency appears frequently. The digital currency wallet launched by CCB app is currently being tested, which is one step closer to the official use of digital RMB
The contract transaction of digital currency is not safe. There are still many loopholes in the digital currency trading platform, for example, the most common ones are as follows:
1. Denial of service attack
denial of service attack is the most important attack against the digital currency trading platform at present. Through the denial of service attack, the attacker makes the trading platform unable to access normally, while the user cannot accurately distinguish the attack degree, It often leads to panic asset transfer, which brings some loss
