The era of credit in blockchain

1. At present, blockchain technology is mainly applied in smart contract, identity authentication and asset transaction

in addition to solving the security problem, blockchain technology can also change the following areas:

1. In the future, music right distribution is likely to enter the stage of blockchain, removing the intermediate link, so that musicians can get more direct income. In the past, record companies or the Internet were required to increase user stickiness. There were a lot of fees in the middle of promotion or song playing, but not many were really given to the authors, because the original right was still in the hands of several major record companies

2. Writing right is the same. For example, you may have to find a publisher before. This right can't be sold many times, and the money given to the author is also very small. With blockchain technology, all users need to pay the right fee to the author, not limited to a single publisher. Previously, Mr. Li Xiaolai did the press one project, which is mainly aimed at right distribution

3. The Internet of things and blockchain technology will combine to proce the blockchain Internet of things (Biot). Blockchain Internet of things can greatly rece the risk of hacker attacks. With the help of blockchain Internet of things, it may be as convenient as mobile phones to obtain warehouse sensor data

Kevin Kelly's book out of control has become the wind vane of the development of the Internet. In his later book necessity, he also mentioned that "technology has a preference in nature, which makes it move in a certain direction. On the premise that other conditions are the same, the physical and mathematical principles that determine the development of science and technology will favor certain specific behaviors

the development of blockchain technology is an "inevitable" trend, and bitcoin and some valuable digital currencies are only proced because of one of the needs. Today's blockchain is like the Internet in 1994. The development of the times will screen out the best technology and procts. It's just a matter of time

now there are too many "pseudo blockchain" projects focusing on blockchain, because too many people blindly invest in them without understanding. I want to make a fortune in this market. Those people are aiming at leeks that enter the coin circle without learning anything. They casually make small packages on the open public chain, issue a coin, hold a roadshow and want to circle a group of people to come in. They want to run after they circle money. In fact, they have no actual technical content and can't solve any practical problems.

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. Yunnan metallurgy used to be called Gejiu Yunxi company, Dongchuan Mining Bureau, Yimen copper mine and Huize Lead zinc mine.

4. It mainly depends on your technology. You can do it separately,
my foreign exchange cost is low, only a little difference, no hand fee

6. Blockchain technology is characterized by anonymity, decentralization, openness and transparency. Blockchain is not a newly invented technology, but an integration of a series of technologies, including asymmetric encryption technology, timestamp, consensus mechanism and so on
taking bitcoin as an example, blockchain solves double spending and Byzantine Generals' problem through timestamp and proof of work mechanism, that is, it ensures that the same bitcoin can not be spent twice, and keeps consistency among all nodes in the whole decentralized blockchain network
the asymmetric encryption mechanism ensures the security of the private key, the timestamp ensures that the blocks are connected into chains in sequence, and the workload proof mechanism solves the problem of how to distribute 21 million bitcoins fairly in the decentralized system.

7. Theoretically, so far, blockchain can represent the highest standard of credit
the block in the concept of blockchain is the information fast formed by the combination of bitcoin information and time stamp, and then every information fast is linked together to form a chain, that is, blockchain. Such chains can be verified with each other, can be added or removed at any node, and the update frequency is extremely fast. The wide range of distribution and the transparent and open data make the blockchain technology have its own credit attribute
the attributes of blockchain technology can be used to centralize the financial infrastructure, disintermediate the credit of traditional intermediate institutions, and evade the risk of financial instry by relying on the security of blockchain technology. However, these technologies can be realized because blockchain technology reflects the value of credit
for example, equity crowdfunding, the traditional way is to promote the completion of crowdfunding activities through equity crowdfunding platform, which is not only inefficient, but also investors can get less return, and the use of blockchain technology can quickly complete the transaction, so that investors can get richer returns, and these returns can be guaranteed, This is e to the distrust intermediation of blockchain technology
of course, as an emerging technology, blockchain must have some myths in the development process. For example, the underlying technologies and protocols of block chaining technology need to be improved, the time of chain formation is not long enough, and the centralization mode is not absolute enough. These problems may lead to the failure, elimination, bubble or new prosperity of the block chain technology. The emergence of this new technology is based on breaking the shackles caused by the lack of contemporary social credit China trade finance website)
the most important function of blockchain is to keep the records of information and not tamper with it. European crowdfunding uses blockchain technology to make crowdfunding project information more transparent.

8. With the rise and continuous development of blockchain technology, many enterprises, institutions and indivials have taken the lead in the field of blockchain for in-depth analysis. At present, blockchain technology is in the rising stage. With the continuous growth and improvement of blockchain technology, it will have the opportunity to become a new credit mechanism based on the bottom decentralization. In the future, jinwowo will focus on promoting the legal circulation and commercial application of big data with blockchain technology, and provide a good Internet big data environment for the majority of small and medium-sized enterprises and users
