Jiuding digital currency

1. Q: What is blockchain technology? A: Blockchain technology can be understood as a public accounting mechanism. It is a technical solution rather than a specific proct. The basic idea is to establish a set of public account books on the Internet, in which all users in the network keep accounts and check accounts together, so as to ensure the authenticity and non tamperability of information. The reason why it is called "blockchain" is that the structure of blockchain storage data is composed of a chain of "storage blocks" on the network. Each block contains all the information exchange data in the network within a certain period of time, and the chain continues to grow over time. Q: What is the relationship between blockchain and bitcoin? A: Bitcoin used to be one of the most successful applications of blockchain technology. Specifically, the blockchain is a series of data blocks generated by the use of cryptography Association, and each data block contains the information of effective confirmation of multiple bitcoin network transactions. It can be said that bitcoin is a "killer application" of blockchain idea. Blockchain is the underlying technology of bitcoin, but its role is not limited to bitcoin. Q: What are the technical features of blockchain? A: Based on open source software and peer-to-peer network, blockchain can bring more advantages than traditional network in currency related fields such as transaction payment. These advantages include: decentralization, no need to trust the system, disintermediation, tamper proof, encryption security. Q: How does blockchain technology improve the authenticity and non tamperability of data? A: The newly added data blocks are linearly added to the end of the original block in chronological order, which constitutes the blockchain. In this process, the data is distributed in each computer. This decentralized storage method improves the authenticity and non tamperability of the data. When a transaction occurs, users all over the world can act as regulators. If we do not recognize the legitimacy of the transaction, the transaction cannot be concluded, and the data on the blockchain is maintained by us collectively. Q: Is there any potential defect in such a brain burning "blockchain"? A: Blockchain also has some defects to be solved, such as security risks, work efficiency and resource consumption. Since the supervision of blockchain depends on all nodes in the network, theoretically speaking, if you master more than 50% of the computing power of the whole network, you will be able to successfully tamper with and forge blockchain data. Secondly, e to the distributed storage, each node in the blockchain needs to keep a database, and any transaction in the network needs to be authenticated and recorded by other nodes, so the efficiency of the system is low. Finally, because the operation of the blockchain relies on the computing power contributed by the network nodes, these computing power do not proce actual social value, so it is generally considered that these computing power resources are "wasted". Application of blockchain in various fields when blockchain technology is published, many people think it is possible to realize DAC. DAC (full name) can be translated into distributed autonomous system, which refers to an organization system that runs autonomously without intervention and management through a series of open and fair rules. DAC has many forms. It may be a digital currency, a system or an entity, or even a driverless car. This kind of organization system can provide valuable services for customers in the form of currency transfer (such as bitcoin), asset transaction, domain name service, or any other business model. Therefore, through the idea of information sharing, blockchain technology is likely to bring profound changes in cost rection and security improvement to various instries. Application scenarios that existing blockchain technology can achieve: proof of existence can be used to confirm rights in the field of Internet finance, that is, blockchain can really realize "proving your mother is your mother". The smart contract guarantees the validity of the contract, such as the generation required by the electronic signature law; Reliability of methods for storing or transmitting data messages; The reliability of the method of maintaining content integrity; The reliability of the method used to identify the sender. The blockchain of the Internet of things can solve the problem of the coding standard interaction interface of the Internet of things. When an e-signature is signed by identity verification, the signature data is only under the exclusive control of the signer. Any changes to the e-signature after signing can be found, and any changes to the content and form of the data message after signing can also be found. The market forecasting community, August, is an example. Anyone can access and use August anywhere in the world, which may bring unprecedented liquidity and trading volume to the market. Asset trading NASDAQ OMX Group Inc is testing blockchain technology, which NASDAQ believes has the opportunity to transform traditional financial trading methods into bitcoin like ones. The bitcoin mode of e-commerce can be applied directly. Is it possible for e-commerce to become a "harmonious" market without supervision? Social news magmavc has invested $400000 in getgems (formerly known as gems), a start-up project for decentralized social communications applications. File storage directly impacts and even subverts the traditional cloud computing architecture. Chain, a data API blockchain API service provider, has received a $9.5 million investment led by Khosla ventures. Wall Street's financial companies are investing in blockchain and seizing the beach. Visa, NASDAQ and Citigroup also invested in chain, an old Jinshan blockchain start-up, with a financing amount of US $30 million. In the financial field, what can blockchain do? Specifically, in the financial field, in addition to providing a trading platform for bitcoin, Jiuding investment believes that blockchain technology can also greatly improve various asset trading systems other than the existing digital currency. For example, it plays an important role in the post transaction market proceres such as the liquidation and settlement of financial derivatives, foreign exchange, private equity, energy credit linked investment procts and other assets. In terms of speed, the time required for settlement audit in the U.S. securities market is 2 to 3 days. The application of blockchain technology is expected to rece the settlement audit time from hour level to minute level or even second level, thus recing the settlement risk by 99%, and recing the capital cost and system risk. In the blockchain, transaction confirmation and settlement are carried out at the same time. After the node transaction is confirmed by the system, it is automatically written into the distributed ledger, and the corresponding distributed ledgers of all other nodes are updated at the same time. The automatic operation mechanism can greatly shorten the settlement cycle. In terms of expenses, under the current settlement mechanism, in order to achieve a shorter settlement cycle, it is necessary to increase the settlement cost and initial investment expenses significantly. The emergence of blockchain technology makes it possible to rece the settlement cycle more efficiently and quickly, and rece the transaction intermediate proceres, so as to save a lot of money, which is the market space of the related blockchain instry. In terms of security, the integration of blockchain technology into smart contract technology can process complex derivatives transactions programmatically, making clearing more standardized and automated. The time linear stacking feature of the block itself can help the regulators identify and discover illegal operations. At the same time, the smart contract can change the compliance inspection into automation and minimize the possibility of violation from the beginning of liquidation. The 24-hour uninterrupted operation of blockchain technology can also make the data exchange processing of Pan state exchange more stable and reliable. In addition to securities transaction settlement, blockchain can also be used to register and issue digital asset ownership. Blockchain technology can greatly enhance program automation, while smart contract can write many complex derivatives trading terms into the registration and issuance program supported by blockchain technology. When a transaction occurs, blockchain network can quickly and correctly execute. In November 2015, LINQ, a new blockchain technology project cooperated by Nasdaq and chain, has completed the first private equity transaction using the blockchain based issuance and trading platform. The application prospect of blockchain in the field of accounting has also attracted the attention of a large number of people in the instry. Accounting, auditing and compilation cost a lot for global enterprises and the four accounting firms. Automatic accounting based on blockchain technology can greatly rece the relevant costs. The company does not need to recruit special auditors to audit the account book, and all transactions can be stored in the internal blockchain. Due to the irreversibility and time stamp function of the blockchain, the external auditors and regulators of the four major accounting firms can monitor the company's account books in real time by tracking these blockchains. At the same time, the institutions can greatly rece the dependence on the auditors to audit financial transactions and make the audit business more efficient. With the increasing maturity and application expansion of blockchain technology, blockchain start-ups in developed countries have sprung up. At present, the world's leading blockchain companies generally focus on transaction, payment, clearing, Internet of things and other pain point businesses. Some companies have achieved a certain scale, and have developed a relatively clear business model. At the same time, many companies have extended their business in the blockchain instrial chain, covering payment, transaction, risk control, etc., making full use of the multi-point coordination effect. At present, Jiuding investment is also focusing on the projects and applications of various blockchain technologies.

2. Blockchain is its underlying application technology, and digital currency is its currency. Its practical application has little impact on the fluctuation of digital currency
when the economy is stable, it doesn't rise. When the economy is in turmoil, people begin to store digital currency. Of course, it is convenient for some corrupt elements
now the economy is stable, the digital currency is in a bear market, the financial crisis, the crisis, and only when there is a crisis can there be an opportunity. At that time, the rapid growth of bitcoin was the opportunity in the financial crisis. Don't worry, there will be a bull market in digital currency, which is expected to come in the second half of next year

3. Jiuding finance and economics live broadcasting room is with these people, and is also a liar. It has been reported to the police for several months, and the public security organ has not made any reply yet

4. The United Nations is an international organization established after the Second World War. According to the Charter of the United Nations signed in San Francisco in June 1945, it was formally established on October 24 of the same year. The 51 countries that signed the Charter are founding members of the United Nations. China is one of the founding members of the United Nations, but e to the obstruction of the United States, the legitimate rights of new China in the United Nations were not restored until October 1971. According to the Charter, the purposes of the United Nations are to "maintain international peace and security", "stop acts of aggression" and "promote international cooperation". The Charter stipulates that the United Nations and its member states shall abide by the following principles: the sovereign equality of all States; Settling international disputes by peaceful means; No threat or force or other means inconsistent with the purposes of the United Nations shall be used to infringe upon the territorial integrity or political independence of other states; The United Nations shall not interfere in matters which are essentially within the domestic jurisdiction of any state. The main bodies are the general assembly, the Security Council, the economic and Social Council, the Trusteeship Council, the International Court of justice and the Secretariat. The headquarters are in New York. There is a European office in Geneva< The charter is the fundamental constitution of the United Nations, which stipulates the rights and obligations of Member States and defines the organs and proceres of the United Nations< According to the Charter, the purpose of the United Nations is to maintain international peace and security; To develop friendly international relations; To cooperate in solving international problems of economic, social, cultural and human welfare nature, and to promote respect for human rights and fundamental freedoms of all mankind; And form a center to coordinate the actions of all countries in order to achieve the above common goals< The six major organs of the United Nations are: the general assembly, the Security Council, the economic and Social Council, the Trusteeship Council, the International Court of justice and the Secretariat. However, the United Nations family is much larger, with a budget of US $2.535 billion for 2000-2001. The main source of funds is the assessed contributions of member states according to the scale approved by the general assembly
the fundamental criterion of the scale of assessments is the capacity to pay of each country. When determining the capacity to pay, the relative share of each country in the total GNP should be taken into account, and adjusted in connection with factors such as per capita income of each country
in addition, countries share the cost of peace keeping operations; In 2000, the cost of peacekeeping was about $2 billion. The basic scale has been revised to become the basis for apportioning the cost

the United Nations family of agencies is composed of the United Nations Secretariat, United Nations programmes and funds, such as the United Nations Children's Fund (UNICEF) and the United Nations Development Programme (UNDP), as well as specialized agencies. Each programme, fund and specialized agency has its own governing Council and budget and sets its own standards and guidelines. Together, they provide technical assistance and other forms of practical assistance in almost all aspects of economic and social activities< The United Nations was established on October 24, 1945, with 51 countries committed to maintaining peace through international cooperation and collective security. Today, almost every country in the world has joined the United Nations. The United Nations has 191 member states< When a country becomes a member of the United Nations, it agrees to accept its obligations under the Charter of the United Nations The Charter of the United Nations is an international treaty, which stipulates the basic principles of international relations. According to the Charter, the four purposes of the United Nations are: to maintain international peace and security; Developing friendly relations among countries; Cooperation in solving international problems and promoting respect for human rights; To become the center of coordinating the actions of all countries
the United Nations is not a world government and does not make laws. But the United Nations provides solutions to international conflicts and formulates policies on matters that affect us all. In the United Nations, all Member States, big or small, rich or poor, regardless of their political views and social systems, have the right to speak and vote in this process
there are six main organs of the United Nations. The general assembly, the Security Council, the economic and Social Council, the Trusteeship Council and the Secretariat are located at the United Nations headquarters in New York. The sixth principal organ is the International Court of justice, which is located in the Hague, the Netherlands< All Member States of the United Nations send representatives to the general assembly. The general assembly is a "world parliament", meeting to consider the most urgent issues in the world. Each member has one vote. Key issues such as the maintenance of international peace and security, the admission of new members and the formulation of the United Nations budget were decided by a two-thirds majority. Other matters are decided by a simple majority. In recent years, the general assembly has made a special effort to take decisions by consensus rather than by formal vote< At its 2001 / 2002 session, the General Assembly considered 180 different topics, including globalization, AIDS, conflicts in Africa, environmental protection and the strengthening of new democratic institutions. The general assembly cannot force any country to take action, but its recommendations are an important voice of world public opinion and represent the moral authority of the international community
the general assembly holds regular sessions from September to December every year, and holds resumed sessions or special or emergency meetings on issues of special concern when necessary. During the recess of the general assembly, the work of the assembly is carried out by the six main committees, other subsidiary organs and the United Nations Secretariat<

the Security Council
the main responsibility entrusted to the Security Council by the Charter of the United Nations is to maintain international peace and security. Whenever peace is threatened, the Security Council can meet at any time. All Member States have an obligation to implement the Council's decisions in accordance with the provisions of the Charter
the Security Council has 15 members. China, France, the Russian Federation, the United Kingdom and the United States are permanent members. The other 10 members are elected by the general assembly for a term of two years. In recent years, member states are discussing the issue of changing the composition of the Security Council to reflect the current political and economic reality
the Security Council needs nine votes to make a decision. Except for the voting on proceral issues, as long as any permanent member votes against (veto), the Security Council will not be able to make a decision
when considering issues that threaten international peace, the Security Council should first explore ways to settle disputes peacefully. The Council may propose principles for settlement or mediate. In the event of fighting, the Security Council strives for a cease-fire. The Security Council may send peacekeeping missions to assist the parties in maintaining a truce and separating hostile forces
the Security Council can take measures to enforce its decisions. The Security Council may impose economic sanctions or order an arms embargo. In rare cases, the Security Council has authorized member states to use "all necessary means", including collective military action, to implement their decisions< The Security Council also made recommendations to the General Assembly on the selection of the Secretary General and the admission of new members of the United Nations< The economic and Social Council coordinates the economic and social work of the United Nations and the organizations of the United Nations system under the overall leadership of the general assembly. As a central forum for discussing international economic and social issues and formulating policy recommendations, ECOSOC plays a key role in strengthening international cooperation for development. The Council has also consulted with non-governmental organizations to maintain key links between the United Nations and civil society
the Council has 54 members elected by the general assembly for a three-year term. The council meets throughout the year, with major meetings in July each year, including a special ministerial meeting, to discuss major economic, social and humanitarian issues
the subsidiary bodies of ECOSOC meet regularly and report to ECOSOC. For example, the Commission on human rights monitors respect for human rights around the world. Other institutions focus on social development, the status of women, crime prevention, narcotic drugs, environmental protection and other issues. The five regional commissions are responsible for promoting economic development and cooperation in their respective regions<

Trusteeship Council
the Trusteeship Council was established to exercise international supervision over the 11 trusteeship territories administered by seven Member States and to ensure that appropriate steps are taken to prepare for the autonomy or independence of the trusteeship territories. By 1994, all trust territories had achieved self-government or independence. Some became independent states, while others joined neighboring Independent States. Finally, Palau, the trust territory of the Pacific Islands administered by the United States, became the 185th member of the United Nations< The Trusteeship Council is now composed of five permanent members of the Security Council. In view of the substantial completion of its work, the Trusteeship Council has revised its rules of procere to enable it to meet when necessary<

the International Court of Justice (ICJ) is the main judicial organ of the United Nations, which is composed of 15 judges jointly elected by the general assembly and the Security Council and is responsible for adjudicating disputes between states. The state voluntarily participates in the proceedings, but if a state agrees to participate, it has the obligation to comply with the court's ruling. The court also advises the general assembly and the Security Council upon request< According to the instructions of the general assembly, the Security Council and other organs, the Secretariat carries out the substantive and administrative work of the United Nations. The head of the Secretariat is the secretary general, who is responsible for providing overall administrative guidance< At present, there are several departments and offices in the Secretariat. There are about 7500 staff in the regular budget, and the number of staff in the special budget is about the same. The staff come from more than 170 countries. The ty stations include United Nations headquarters in New York and United Nations offices in Geneva, Vienna, Nairobi and other locations<

the United Nations system
the International Monetary Fund, the world bank and 12 other independent organizations called "specialized agencies" maintain contact with the United Nations in accordance with cooperation agreements. The World Health Organization and the international civil aviation organization also belong to this category. These are self-governing bodies established by intergovernmental agreements. These institutions have a wide range of international responsibilities in the economic, social, cultural, ecational, health and related fields. Some of them, such as the international labor organization and the Universal Postal Union, were founded earlier than the United Nations
in addition, some United Nations offices, programmes and funds, such as the office of the United Nations High Commissioner for refugees, the United Nations Development Programme or the United Nations Children's fund, are responsible for improving the economic and social conditions of people around the world. These bodies are accountable to the general assembly or the economic and Social Council

all of the above organizations have their own governing body, budget and Secretariat. These organizations, together with the United Nations, are collectively referred to as the United Nations family, or the United Nations system. Together, they provide technical assistance and other forms of practical assistance. It covers almost all economic and social fields
● the United Nations has formulated the Universal Declaration of human rights (1948), which is of great historical significance, and has formulated more than 80 human rights treaties that help to protect and promote specific rights
● UN peace keeping operations are important tools for peace keeping. Currently, 87 countries provide about 47650 United Nations military and civilian personnel to carry out 15 peace keeping operations around the world
● the United Nations
