Today, the international market belongs to blockchain

1.

blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects

on January 10, 2019, the state Internet Information Office issued the regulations on the management of blockchain information services. In October 24, 2019, ring the eighteenth collective learning of the Central Political Bureau, general secretary Xi Jinping stressed that "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". "Blockchain" has entered the public field of vision and become the focus of social attention

related extension: blockchain financial application:

since 2016, the major financial giants have also carried out blockchain innovation projects to explore the possibility of applying blockchain technology in various financial scenarios. In particular, Puyin group took the lead in creating a "blockchain +" standard digital currency

standard digital currency refers to the process of assets identification, evaluation, right confirmation and insurance completed by a third party organization, which is written into the blockchain through careful digital algorithm to form the standard corresponding relationship between assets and digital currency, which is called standard digital currency

in order to realize the great leap forward development of blockchain finance, promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that has been struggling for generations, Puyin group will hold the Guiyang strategic development ceremony of Puyin blockchain finance in Guizhou on December 9, 2016

the meeting will discuss the realization of digital circulation of assets by blockchain, the financial transaction mode of blockchain, and the application of blockchain services and social public instry. This conference will mark the beginning of the application of blockchain finance and the change and development of the new financial ecology

on June 1, 2020, Xinhua news agency was authorized to broadcast the "overall plan for the construction of Hainan free trade port" issued by the CPC Central Committee and the State Council, which will "actively participate in the formulation of international rules for cross-border data flow, and establish standards and rules for data rights confirmation, data trading, data security and blockchain finance" as one of the key tasks of Hainan free trade port before 2035

2. Blockchain mainly solves the trust and security problems of transactions, so it proposes four technological innovations to solve this problem:
(1) distributed ledger, that is, transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, so they can participate in monitoring the legitimacy of transactions, At the same time, they can testify together
different from traditional distributed storage, the uniqueness of distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to block chain structure, while traditional distributed storage generally stores data in multiple copies according to certain rules. Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes[ 8]
no single node can record the account data separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. In theory, unless all the nodes are destroyed, the accounts will not be lost, so as to ensure the security of the account data
(2) asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
(3) consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security
the consensus mechanism of blockchain has the characteristics of "the minority is subordinate to the majority" and "everyone is equal", in which "the minority is subordinate to the majority" does not completely refer to the number of nodes, but also can be the computing power, the number of shares or other characteristics that can be compared by computers“ "Everyone is equal" means that when the nodes meet the conditions, all nodes have the right to put forward the consensus results first, and then directly recognized by other nodes, and finally may become the final consensus results. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes in the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) smart contract, which is based on these trusted and tamperable data, can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts

Fried coins or something

at present, the application of blockchain technology is virtual currency. Therefore, virtual currency is also known as the first real birth proct of blockchain. The popularity of virtual currency is also obvious to all, which has set off a frenzy of investment in many countries. According to foreign media reports, the number of virtual currency transactions in the United States has reached 5 million; South Korea is estimated to be the craziest nation in the world, with one in every 50 people speculating, and 31% of the working class buying and selling virtual currency; Venezuela has also issued the world's first virtual currency with the nature of national sovereignty - oil currency

with the popularity of virtual currency, market investors are not only satisfied with the conventional trading mode of buying low and selling high, but also actively seek more simple and convenient trading ways to obtain more profits. The virtual currency trend trading method was born and successfully captured the hearts of investors in a short time, becoming a major mainstream trading mode

according to

{rrrrrrr}

, the trend trading method of virtual currency is exclusively launched by speedxo, an international financial service provider with deep experience. It mainly deals with the currency pair composed of virtual currency and real currency, and it can make profits as long as it is bullish or bearish. For example, if an investor trades in "bitcoin / US dollar", he or she only needs to judge whether the price will rise or fall after 30 seconds, and buy up or down according to the trend. If he or she buys in the right direction after 30 seconds, he or she can get 93% of the net income of the investment amount. It is this kind of rise and fall are profitable, time-consuming, no need to take advantage of the market, the trend trading method quickly swept the entire currency circle

5. Recently, the hottest topic is blockchain. The 24 eldest brothers formed a team to learn blockchain. This event can be regarded as an epic good in the blockchain circle. Starting from the evening of the 25th, bitcoin soared 40% in one day, and then more than n domestic concept coins soared in turn. The whole coin circle was beaten to death. Many aunts in the circle of friends microblog began to study blockchain; On the stock market, the blockchain sector is also very lively, with more than 1000 listed companies claiming to lay out the blockchain field. This shot is really 666. I remember everyone was busy getting rid of blockchain before! It's really forgetful
in a few days, the safe also released the blockchain development plan. It seems that the whole world will be transformed by blockchain. Many people have a kind of blockchain application, which will give the currency transaction and foreign exchange transaction a false identity
blockchain has a natural anti censorship international nature in terms of asset transaction and circulation, and can freely and conveniently circulate without the constraint of traditional concurrent management. On the one hand, there is a great risk, so the safe also said that in China, only RMB can be used for pricing, and anything that may threaten this basis should be prohibited. In a short period of time, it may be difficult for blockchain to achieve anything at the level of foreign exchange transactions. The foreign exchange bureau mentioned the application scenarios of blockchain technology in cross-border trade financing and macro Prudential Management. This direction belongs to the pure technology application direction, which is less related to transactions. At present, it is also the direction that the top priority is to develop, using blockchain technology to optimize the real instry
how to optimize it? Because blockchain has the characteristics of traceability, distributed transparency, tamper proof, etc., for example, in cross-border trade, the data of related parties involved in trade are linked and opened to third parties (such as banks) with permission. In the past, enterprises may need more practical asset mortgage to borrow money from banks, Now, by associating reliable trade data on the blockchain, the bank can know the future cash flow of the enterprise, and can use the operation of the enterprise as asset mortgage to give credit. This will greatly optimize the allocation of assets
another example is the patient information in the hospital. The traditional scenario is that the data of each hospital is independent. Every time you go to a new hospital, you will be asked to do a booklet or a set of examinations. If there is a medical chain open to all hospitals and all information is recorded in this account book, you can avoid a lot of plication and simplify efficiency
it is clear that the priority is to develop blockchain technology to optimize and transform traditional instries, with the focus on the combination with the real economy. I am also very optimistic about this, but in terms of asset trading, the expectation of currency trading and foreign exchange trading should not be too high. After the excitement, it will be calm.

6. There are many blockchain content projects in China, such as coin, stemmit, etc. However, aqua is a relatively distinctive blockchain content project. The owner can download its DAPP to observe its difference from other projects. It is very creative in terms of publicity, objectives and functions. I hope it can help you.
