Blockchain craze

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

2. Blockchain is the biggest trend in the next decade
if you look at the problem with the thinking of 30 years ago, you will think that others are crazy, but in fact you are out of date
the concept of blockchain can be traced back to the end of 2008. In the forum, a mysterious personage named "Nakamoto Tsung" published a paper "bitcoin: a peer-to-peer e-cash system" and proposed the concept of blockchain for the first time
on January 3, 2009, the first block of the blockchain was born, which is called the "Founding block"
almost with the birth of blockchain technology, bitcoin became the first thing to play its role. In the following years, bitcoin graally swept the world. In 2017, its crazy market made blockchain technology known to all
the idea of blockchain first appeared in the famous bitcoin open source project. In the process of its birth and development, bitcoin project draws on the technical achievements from digital currency, cryptography, game theory, distributed system, cybernetics and other fields. It can be said that bitcoin project is good at all. As its core supporting structure, blockchain technology is a remarkable innovation achievement
blockchain is a distributed database system with different nodes, which is an open ledger system<
three characteristics of blockchain
compared with the traditional centralized scheme, blockchain technology mainly has the following three characteristics:
the core idea of blockchain is decentralization
in the blockchain system, the rights and obligations between any node are equal, and all nodes have the ability to vote with computing power, Thus, the result recognized by more than half of the nodes is guaranteed. Even under serious hacker attacks, as long as the number of nodes controlled by hackers does not exceed half of the total number of nodes in the world, the system can still operate normally and the data will not be tampered with
block chain's biggest subversive is the establishment of credit
the collective maintenance of blockchain can rece the cost
in the centralized network system, the maintenance and operation of the system depend on the operation and operation of platforms such as data center, and the cost cannot be omitted. Anyone can participate in the nodes of the blockchain. Each node can verify the correctness of the results of other nodes' records while participating in the records, which improves the maintenance efficiency and reces the cost
in a word, blockchain touches money, trust and power, which are the fundamental basis for human survival< Its development has gone through three stages
1. Brewing period: from 2009 to 2012, bitcoin and its instrial ecology are the main economic forms
2. Embryonic period: from 2012 to 2015, with bitcoin entering the public view, new wallet payment and remittance companies appeared, and blockchain economy spread to the financial field. The underlying technology of blockchain is constantly innovated. Blockchain technology is separated from bitcoin system
3. Development period: in 2016, we began to explore instry applications, and a large number of blockchain start-ups appeared. The popularity of ICO in 2017 has given blockchain unprecedented attention
"blockchain 2.0 era" is coming
the application service layer is the driving force for the sustainable development of blockchain, which is divided into three stages of application: 1.0, 2.0 and 3.0
programmable currency: blockchain 1.0 application
programmable currency is the digital currency represented by bitcoin, but it is not the legal tender of any country or region, and there is no government authority to provide guarantee for it
programmable Finance: blockchain 2.0 application& quot; Smart contract& quot; Using program algorithm to replace the concept of contract execution. This enables blockchain to expand from the original monetary system to the registration and transfer of equity, creditor's rights and property rights, the transaction and execution of securities and financial contracts, and even the financial fields of gambling and anti-counterfeiting
programmable Society: blockchain 3.0 application
blockchain is the core of value Internet, which can confirm, measure and store the property rights of information and bytes representing value in each Internet. It can not only record the transactions of the financial instry, but also record almost anything valuable that can be expressed in the form of code. Its application can be extended to any field with demand, and then to the whole society
at present, the application of blockchain has begun to surpass bitcoin (blockchain 1.0), enter the era of blockchain 1.5, and transition to the financial field (blockchain 2.0)
in the next 3-5 years, blockchain may go beyond the financial field and enter the field of social notarization and intelligence (blockchain 3.0), including identity authentication, notarization, arbitration, audit, domain name, logistics, medical care, mail, visa, voting and other fields. Its application scope will be expanded to the whole society, and blockchain technology is likely to become a new technology& quot; All things are connected& quot; It's the lowest level protocol
at present, blockchain technology has been recognized by the world, and its development has become an inevitable trend. Accompanied by more people's attention, "in the next 30 years, new technologies will be integrated into all aspects of traditional instries, and human society will turn upside down. No matter who you are, no matter where you are, all of us will be a part of this great change."
this is the current situation. Blockchain has given the post-90s an opportunity. However, if you want to control blockchain technology without being affected by negative factors, the most important thing is to have a clear understanding of it, whether it is regulators, researchers, speculators or bystanders
it's time to devote more energy to blockchain technology
in China, the average annual salary of blockchain positions has reached more than 300000, and that of some enterprises has reached more than 1 million. The monthly salary of blockchain instry graates in Beijing, Shanghai and other places has exceeded 20K! If the post-90s seize the bonus of the times, they may become the next Alibaba in the future! If you miss it, you may regret it for ten years.

3. 1. Control
generally speaking, bitcoin and cryptocurrency tokens provide you with more control. You effectively cut the middleman between you and your money. No bank can decide how long a transaction will take and how much it will cost. You can also control where funds are stored and how they are accessed. Of course, control brings corresponding responsibilities
2. Affordability
since the middleman is not in the picture, you can save some transfer fees. Moving bitcoin from one wallet to another costs a negligible amount of money. It is cheaper for businesses to accept bitcoin payment than credit card payment
3. Speed
in addition to saving international transfer fees, you can also enjoy higher transaction speed. What does it take your bank a few days to do? Bitcoin can do it in a few minutes
4. Convenient
with bitcoin, online payment is easier and faster. If you want to donate or pay for something that will not be delivered, you do not need to disclose any personal details. Just send bitcoin to their wallet address
5. Security
it is safer for businesses to accept bitcoin than fiat money. When businesses accept credit card payments, they risk fraud and reverse payments. Bitcoin payment is irreversible, so there is no risk of reversal
6. Privacy
one of the main advantages of using bitcoin is that it provides privacy and relative anonymity. You don't need to provide any personal details to access the bitcoin wallet. All you need is a device to store it - even a piece of paper. Bitcoin transactions are only linked to your wallet address
7. Reliability
bitcoin network is essentially a point-to-point payment system. This allows you and you to remit money to anyone who participates in the party. You don't have to rely on the bank to do the work to make the transaction effective. In Ethernet, the risk of payment loss is small, which eventually makes it a more reliable way of payment
8. Investing in
bitcoin wasn't worth a lot of money ten years ago. Let's see where it has been since 2009. From a few dollars in December 2017 to nearly $20000. At the time of writing, it is now stable at around $6000. As more and more people adopt bitcoin, bitcoin will not be everywhere. Investing in it may be risky, but it's absolutely profitable.

4. DAPP has been widely used since Ethereum's smart contract came out.

5. The essence of these virtual currencies is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite solutions of a system of equations. Every particular solution can solve the equation and is unique
you can think that the action of digging virtual currency is to use the graphics card to do continuous general computing, and the computational complexity is relatively low and quite repetitive. The stream processor used by the graphics card is just suitable for such an algorithm
therefore, we used graphics cards to mine virtual currency at the beginning. After that, someone developed a specific algorithm to make the stream processor of the graphics card greatly strengthen the virtual currency solution, which is the origin of the mining machine.

6. First of all, because the opponent's immortality is the beginning of spider flow, the first response is the swordsman. After clearing a group of wild monsters, the swordsman should always harass the opponent's MF (enough red and blue medicine on his body), and when he has about three big G's, he will engage in a small-scale battle with the opponent to rece the number of the opponent's spiders and delay the opponent's technological speed. After Tauren comes out, it will quickly move to level 3. At this time, there should be at least 5 big G's and 3 wolf's riders who have already risen their nets. They can seek a decisive battle with one attack and one defense. Tauren should be equipped with acceleration, invincible, blue bottle and shoes. They are mainly used to kill each other's spiders. If they can limit the number of spiders, harass each other's MF level and ensure their hero level and army number from beginning to end, It shouldn't be hard to win
it is recommended to refer to fly's RP.

7. A virtual currency on the Internet

can be used to make money for a period of time

it can be converted into RMB by mining or other transactions

but China does not support it

8. The process is published on the platform. It is generally the process of submitting information, condition audit, resource matching and reaching cooperation. I read it specially. It was jointly launched by Hunan souyun Technology Co., Ltd. and Jiangsu, Gansu and Hengdian exchanges of culture and culture. The script, project and advertising resources are pretty good.

9. With the rapid popularization of mobile payment, people have rich reverie about "cashless society". China is the most widely used country of mobile payment in the world, and also one of the countries closest to "cashless society". However, only relying on mobile payment can not meet the reform requirements of the digital financial era, and the concept of "digital currency" with a deeper focus came into being.

10. Blockchain exploded at the end of 2017. It was influenced by the soaring bitcoin, thunderbolt, storm broadcast, cloud control, Renren blockchain and even Kodak. For a time, the slightly strange technology of "blockchain" seemed to be a magic drug for the stock price to come back to life. Even the prices of counterfeit tokens related to blockchain are like flying
different investors have different views. No matter they think it's a bubble sworn faction, or they regard it as a good candidate for the draught, they do not deny that the block chain is a tool that people can not ignore to change the society. Therefore, it is an important choice to join the blockchain investment platform.
