Blockchain process

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

on December 2, 2019, the word was selected into the top ten catchwords of "biting words" in 2019

extended data:

Application of blockchain Finance:

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

first, define the

blockchain as an open network ledger. It originated from bitcoin and is the underlying technology of bitcoin. In bitcoin transactions, all the information of transaction records will be packaged into a "block" for storage. With the expansion of information exchange, one block links with another, forming a blockchain

Second, the digital currency represented by bitcoin is a point-to-point e-cash system. Among them, every transaction will broadcast to all participants in the network, and it will be recorded in the account book after repeated confirmation, which is called "blockchain". Each participant will have his own account book. In this way, when false information occurs, it can be broken through mutual verification, so as to ensure network security

in the blockchain, every node is equal, and there is no centralized management organization. This "decentralized" feature makes the blockchain do not need to rely on a third party, its operation does not need any human intervention, and it can independently conct self verification. In addition, the network of blockchain is open to the world, and anyone can query data through the public port, so the whole system is highly transparent

In a word, blockchain is a reliable database and a reliable "account book". In the future, it will be applied in cross-border payment, securities, loans, voting, etc. For example, in cross-border payment, with the security of blockchain, you can remit money to the world anytime and anywhere, which saves a lot of intermediate links and high fees

3. First of all, we must pass the technical audit. Different exchanges have different needs. Most of the processes are relatively simple, but the audit takes a long time. Star Trading in the audit will be very fast, on the currency process do not understand the place there is a special 1v1 service, simple and fast.

4.

Seeing some answers to the debate on the definition of blockchain, I suddenly realize that my answer to this explanation principle has always been directed at bitcoin. There is no specific and unique answer in the instry between the definition of blockchain. Here I first summarize the characteristics of "blockchain" according to the papers I read:

1; Hash chain & quot There are several nodes participating in the system operation (distributed)

3. Reach a consensus on the consistency of basic data (consensus agreement / algorithm) through a certain protocol or algorithm

since bitcoin is currently one of the most typical and influential applications of blockchain, it will be much easier to understand how bitcoin uses blockchain before understanding other forms of blockchain applications

5. The procurement process includes information collection, inquiry, price comparison, price negotiation, evaluation, sample request, decision, requisition, order, coordination and communication, expediting, purchase acceptance and payment.

6. First of all, suppose a person with an empty backpack who has just started the game. On the first morning, it's better to roll the trees first to get enough boards and sticks, and make a wooden manuscript ahead of time. When you see the sun to the west, you're going to start looking for the mine

how to find it<

first press "m" to change the map type to cave

the place with deep color on the map is the mine cave, and the place with light color indicates high altitude.

if you can't see the mine cave, it means there is no cave in a certain depth, then you can try to dig down for a period of time, and generally you can see the mine cave

now what you need to do is to find a small mine - because what you need to do is not to dig, but to find a center for your mine

it would be better if you could get some coal

when you get to the mine cave, you'd better not dig the mine first, which may cause you to fall into a big mine cave

don't act rashly after you find the mine cave, check the whole cave first, and insert the torch. Seal all entrances to the ground

you can make a workbench first

you can also consider making a box, but I don't recommend that unless you have enough wood

you have to wait here for the next day unless you have a bed

on the second day, the first thing is to get out of the cave and build a cabin above your mine cave. It should be fully equipped with boxes, furnaces and fires. It's better to have a bed and a door. It's also necessary to figure out with the mine cave, but it's necessary to put a trap door to prevent monsters from climbing up in the middle of the night

you can do these things in a day

on the third day, you will start mining. First of all, you should take a good wooden manuscript (if you have stone, you can use stone manuscript), torch, food, wooden sword, and bow and arrow

and some stone and wood

of course, if there are stones, first integrate stone manuscript and stone sword< In the early stage, there were two kinds of most important ores:

coal mine and iron mine

iron ore is a necessary tool for making iron tools

if you want to excavate from your mine, you'd better make a door to separate your mine from other mines

the best shape of the excavated mine is 2 * 2 square type

if monsters are found, they should be eliminated in time, especially JJ monsters

remember, don't go into the big mine blindly, and don't go into the underground Canyon or abandoned mine.

Bitcoin is a kind of cryptocurrency based on decentralization, using peer-to-peer network and consensus initiative, open source, and blockchain as the underlying technology

on January 3, 2009, Chuangshi block was born. Anyone can participate in bitcoin activities and issue bitcoin through a computer operation called mining. Since the number of bitcoin protocols is up to 21 million, some people think that inflation can be avoided

in 2010, bitcoin proced a price in the transaction, and the initial price was about US $0.0025 per coin. If compared with the current $30000 each, the "value" of bitcoin has increased by more than 12 million times in about 10 years

many people in the "coin circle" believe that the players behind bitcoin are no longer technicians and blockchain enthusiasts, but global financial institutions

when bitcoin and other blockchain digital assets increasingly get the participation of mainstream investment institutions, it will help to rece the concern about the legitimacy of bitcoin

in November 2020, PayPal, an online payment giant with more than 300 million users, announced to provide bitcoin trading services for qualified US customers after purchasing a large number of bitcoin

in December 2020, Singapore DBS Bank launched bitcoin and other digital asset trading services for institutional investors. In the past three years, the bank has been calling bitcoin a Ponzi scheme...

however, the soaring virtual currency represented by bitcoin has not changed the reality that it is not generally recognized by the mainstream financial market, which means that the higher the value of bitcoin, the higher the value of bitcoin, The more risky investors are

After all, behind the virtual currency, there is nothing but artificial scarcity caused by technology

8. Print to the nearest Social Security Bureau
there are three types:
1.

therefore, enterprises sometimes mention that printing enterprise payment details is actually printing payment notice; In the system, the enterprise can not see the details of the payment to a specific employee. If you want to know, you can enter the ID number of the employee in the social security center to inquire, or the employee will log in to the Tianjin city's human resources or social security net to inquire. Basic medical insurance is a social insurance system established to compensate workers for the economic losses caused by disease risks. Through the payment of employers and indivials, the medical insurance fund is established. After the medical expenses of the insured are incurred, the medical insurance agency will give certain economic compensation, so as to avoid or rece the economic risks caused by the illness and treatment of workers
basic medical insurance is one of the most important types of insurance in the social insurance system, which, together with basic endowment insurance, work-related injury insurance, unemployment insurance and maternity insurance, constitutes a modern social insurance system
on May 1, 2016, provinces (autonomous regions and municipalities) that have paid more than 20% of the basic endowment insurance for enterprise employees will rece the payment ratio to 20%
provinces (autonomous regions and municipalities) with 20% of the unit contribution and more than 9 months of the accumulated balance of the basic endowment insurance fund for enterprise employees at the end of 2015 can rece the unit contribution to 19% in stages, and the period for recing the rate is temporarily two years. The specific plan is determined by each province (region, city)
