Post blockchain economy

1. blockchain is a public accounting mechanism
blockchain is decentralized, tamper resistant and anonymous
the blockchain system is actually a distributed system
bitcoin system is the earliest blockchain system and the simplest blockchain system
the whole bitcoin system is actually a distributed ledger. This ledger is backed up on each node. When a transaction occurs, it will be broadcast to the network. The miner node (the node solving the problem) in the network will mine (the node solving the problem) to record the transaction. The recorded block will be broadcast to the network, and other nodes will verify and synchronize to their own node's account book.

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if you look at the problem with the thinking of 30 years ago, you will think that others are crazy, but in fact you are out of date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.

From last year when I entered the field of blockchain and became a member of the coin circle, I found that there are many ways to make money from blockchain. It depends on what you can do to make money

< HR / >

first of all, the most direct way is to speculate in digital currency in the exchange . In the initial stage, you can choose some mainstream currencies with high value, such as bitcoin and Ethereum

the fifth way is other special ways . This is another special way, including helping some project parties do community operation, you will get some token, or helping the project parties write white papers, you can also get a certain amount of token reward

there are probably several ways to make money in blockchain. I wish you an early realization of wealth

4. ① What is digital assets
MBA think tank defines "digital assets": digital assets refer to non monetary assets owned or controlled by enterprises, existing in the form of electronic data, held in daily activities for sale or in the process of proction

in our life, direct consumption in Alipay is a common way to use digital assets, that is, the electronic payment system. Besides, we often use network office, Internet stocks, online reading or video broadcasting, which are using digital assets. For enterprises, online coupons or points are the use of digital assets, and some companies also distribute equity in the form of digital assets

2. Why digitalize assets<

as for the allocation of private digital assets, Xiao Feng, vice chairman of Wanxiang holdings and chairman of Tonglian data, said at a financial technology investment summit that in order to get more than expected returns, it means that we must adopt a different way of asset allocation from others. In the future, the most obvious opportunity for alternative asset allocation may be digital assets. In the next 10 years, This new asset class cannot be ignored. For the society, asset digitization is a major trend

the bat empire is soaring in the digital economy of the Internet. In recent years, Didi, meituan, P2P lending and ofo are all inseparable from two key factors: asset circulation and sharing economy. The most convenient way of asset circulation is undoubtedly to digitize assets! The essence of sharing economy is to make the real assets more convenient for resource sharing through intelligent digital way. Through technical means to rece the waste of resources and rece costs

for enterprises, asset digitization is the best solution to rece costs and increase efficiency. If the privacy file is encrypted and saved by technical means, the security will be far greater than that in the entity. And digital assets are also convenient for enterprises to manage. When the era of big asset management comes, asset management needs to face thousands of asset types, involving a large number of calculations, which can not be completed by manpower alone

③ why use blockchain technology to digitize assets

1. Distrust. Through the distributed system of the blockchain, the trust between people is transferred to the trust in the machine, and the machine will not cheat people - it has no feelings and only operates in its own way. This greatly reces the number of central links generated by trust. In some instries, intermediaries can even be removed. Supply and demand trust is entirely based on this magical machine

2. Decentralization. At present, if you want to transfer the equity you hold, you have to go through a lot of proceres and find different departments to do it well. It's a waste of time and money. If blockchain technology is combined with electronic contract, this problem can be solved. Shareholders can trade their shares just like buying and selling T + 0 shares, and they are also protected by law. What about cross chain technology Cross chain: for example, you directly use your shares to buy other people's digital rights, recing the steps of exchanging legal currency.) How convenient that would be

3. Highly transparent. Now the business's biggest fear is information opacity. The application of blockchain technology can solve this problem. As long as the public digital assets are set up, everyone can view them. If necessary, the number of assets held by the owner can even be displayed, and some shady transactions can be avoided

4. Anonymization. We often do "streaking" on the Internet carelessly. Our information is sold at a price in some bad companies. We check all the system records of a person for several hundred yuan. We can receive some sales calls from time to time in our daily life, and most of the fraud calls are successful only after we know your information. In the blockchain, we only display one address for transactions, which can effectively protect our own information and rece the possibility of information being sold publicly

blockchain technology is a "customized" technology for its security, confidentiality, openness and transparency in asset digitization.

5. 1、 Blockchain will play the role of "recing costs for the real economy". At present, the high cost and low profit of the real economy lead to the lack of capital support for the real economy. In the operating cost, the proportion of management cost and financial cost is not low. Blockchain technology can effectively help enterprises rece the cost of these two parts
secondly, blockchain will play a role of "improving the efficiency of instrial chain collaboration". Enhancing instrial collaboration is an important way to promote manufacturing in China to move towards the middle and high end. However, in many instries, the efficiency of instrial chain collaboration is still not high, especially in the field of international trade
thirdly, blockchain will play a role of "building an honest instrial environment". At present, the construction of China's social credit system is accelerating, but in some cases, the process of building trust among partners is still slow, it is difficult to obtain all kinds of credit information, and it is difficult for small, medium and micro enterprises to obtain credit loans from financial institutions. Through the "transaction on the chain", all aspects can more easily find out the accurate historical credit situation of the counterparties, and establish the cooperation mechanism faster; Banks can also give credit to enterprises more safely based on transaction records, and promote the solution of the problems of "difficult, expensive and slow financing" of small, medium and micro enterprises operating in good faith
in addition, blockchain can make use of smart contracts to avoid default and fraud to a large extent, and can also make efficient and convenient payment scenario applications in combination with blockchain asset wallet. As early as in the blockchain circle, there have been many innovation forums and Instry Summit aiming at the direction of blockchain enabling the real economy, and combining with the local economic instry to carry out landing optimization. For example, the world blockchain conference Macao station intends to make a deep integration with the local economic instry, and use and popularize the blockchain assets with the payment means of magic chain wallet.

6. Principle of blockchain: decentralized distributed accounting system
the core of blockchain technology is that all participating nodes jointly maintain the transaction and database, which makes the transaction based on the principle of cryptography rather than trust, so that any agreed parties can directly carry out payment transactions without the participation of a third party< br />?
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the blocks of the transactions that have been reached are connected together to form a main chain, and all the nodes participating in the calculation record the main chain or part of the main chain. A block contains the following three parts: transaction information, hash formed by the previous block, and random number. Transaction information is the task data carried by the block, including the private keys of both parties, the number of transactions, the digital signature of electronic currency, etc; The hash hash formed by the previous block is used to connect the blocks and realize the sequence of past transactions; Random number is the core of the transaction. All miners compete to calculate the answer of the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for updating, so as to complete a transaction

1.1 what is a blockchain

blockchain is a technical solution to collectively maintain a reliable database through centralization and de trust in the past. This technical solution mainly allows any number of nodes in the participating system to generate a series of data blocks by using cryptographic methods. Each data block contains all the information exchange data of the system in a certain period of time, and generates a data fingerprint to verify the validity of its information and link to the next database block< br />?
generally speaking, blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems, that is, a big ledger. So it's very important who keeps this account book. At present, whose system is responsible for bookkeeping, the account book of each bank is the account book of each bank, and the account book of each bank is the account book of Ali. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there are new transaction data changes in a certain period of time, everyone in the system can make bookkeeping. The system will judge the fastest and best bookkeeper in this period, write the recorded content into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. As a result, the data becomes very secure. Tamperers need to modify more than half of the system node data at the same time to truly tamper with the data. The cost of such tampering is so high that it is almost impossible. For example, bitcoin has been running for more than seven years, and countless hackers around the world have tried to attack bitcoin, but so far there have been no trading errors. It can be considered that bitcoin blockchain has been proved to be a safe and reliable system< br />?

1.2 why is there blockchain innovation

human beings need to communicate in the process of activities, and communication is based on information. In the past, information circulation was not convenient enough to meet the information needs of market participants, so the intermediary and center were born. This centralized system has the problems of high cost, low efficiency, scattered value, "information island" and unsafe data storage. However, e to technical and environmental factors, this system still continues to operate for many years until the emergence of the Internet. The starting point of the first generation Internet is TCP / IP protocol, which is to implement the open code of peer-to-peer transmission of information in a unified format of all nodes on the network, and to program, protocol and execute the basic values of freedom and equality needed by the global unified market. Internet eliminates the middle chain of low value and high cost, and realizes the low cost and high efficiency of global information transmission by decentralization< br />?< However, the first generation Internet did not solve the credit problem of information. The activities that can be decentralized on the Internet must be those that do not need credit endorsement, and those that need credit guarantee must be those that are centralized and participated by third-party intermediaries. As a result, Internet technology, which is unable to establish global credit, has encountered great obstacles in its progress - people can not participate in any value exchange activities on the Internet in a decentralized way. In order to realize value exchange, people still need the third-party intermediary (such as bank, clearing, exchange) based on credit. There are still some problems in the global centralized credit system, such as high operating cost, low efficiency and vulnerability to attack. For example, the legal currencies of different countries have different credit values and different clearing systems, which increase the cost of Global trade< br />?
therefore, what the second generation Internet must break through is: how to decentralize the establishment of global credit? So that the value transfer is also low-cost and efficient. We need to create a kind of technology in the Internet, which can also engage in value exchange activities on the premise that people can't trust each other, so as to achieve real decentralization and go to the third-party intermediary, and realize the transformation from information internet to value Internet

1.3 application of blockchain

Bubi blockchain has been applied to equity, supply chain, points and other fields, and is carrying out experiments and application tests with exchanges and banks
as an integral application on Bubi blockchain, Shubei Hebao has been launched recently, which is a good demonstration for the landing application of blockchain technology in various instries

1.4 why the financial instry needs blockchain

trust is the foundation of the financial instry. In order to maintain trust, the development of the financial instry has spawned a large number of high-cost, low-efficiency, single point of failure intermediaries, including trusteeship, third-party payment, notaries, banks, exchanges and so on. Blockchain technology uses new encryption authentication technology and decentralized consensus mechanism to maintain a complete, distributed and tamperable account book, so that participants can ensure the security of funds and information through a unified account book system without mutual recognition and trust. This is of great significance to finance. Therefore, global financial giants are exploring blockchain applications one after another. On the one hand, this is to prevent the risk of being subverted; on the other hand, it is also "for our own use" to improve efficiency and rece costs, so as to consolidate, optimize and expand the existing power< br />?
first, blockchain can rece trust risk. Blockchain technology has the characteristics of open source and transparency. The participants of the system can know the operation rules of the system, verify the authenticity and integrity of the account book content and account book construction history, and ensure that the transaction history is reliable and has not been tampered with, which is equivalent to improving the accountability of the system and recing the trust risk of the system. For example, blockchain can avoid the current Internet Financial P2P running, fraud and other events< br />?
secondly, blockchain can improve the efficiency of payment, transaction and settlement. On the blockchain, the process of transaction confirmation is the process of clearing, settlement and auditing. Blockchain uses distributed accounting, all transactions are displayed in real time on a spreadsheet similar to global sharing, real-time clearing, and efficiency is greatly improved. For example, the U.S. securities settlement system is t + 3, but the blockchain can improve the efficiency to the minute level, which can rece the settlement risk by 99%, thus effectively recing the cost of capital and systemic risk< br />?
thirdly, blockchain can rece operating costs. Financial business systems and back office work are often faced with long processes and multiple links. Nowadays, no matter visa, master or all of them operate in a centralized way, money transfer has to go through a third party, which makes the cost of cross-border transaction, currency exchange rate, internal accounting and time cost too high, and brings risks to capital. Blockchain can simplify and automate the lengthy financial service process, rece the interaction between foreground and background, and save a lot of human and material resources, which is of great significance to optimize the financial business process and improve the financial competitiveness. The Bank of Spain believes that by 2022, blockchain technology will help the financial instry rece its bookkeeping costs by $20 billion< br />?
fourthly, blockchain can effectively prevent failures and attacks. The traditional financial model takes the exchange or bank as the center. Once the center fails or is attacked, the whole network may be paralyzed and the transaction will be suspended. The blockchain is supported by many distributed nodes and computer servers on the point-to-point network. The problems of any part will not affect the overall operation, and each node keeps a of the blockchain data. Therefore, the built-in business continuity of blockchain has high reliability and fault tolerance< br />?
fifthly, blockchain can improve the level of automation. Since all files or assets can be represented in the form of codes or ledgers, smart contracts and automatic transactions can be realized on the blockchain by setting the data processing program on the blockchain. For example, a smart contract can write a set of financial terms into the agreement to ensure the automatic execution and default payment of the contract< br />?
sixth, blockchain can meet regulatory and audit requirements. The records stored on the blockchain are transparent, traceable and unchangeable. Any record, once written to the blockchain, is permanent and cannot be tampered with. Any transaction between two parties can be tracked and inquired< br />?
in addition to the above positive effects on existing systems and business models, blockchain can also drive the birth of new business models. On the one hand, the characteristics of blockchain technology enable it to achieve some business models that are difficult to achieve in the centralized mode. On the other hand, blockchain greatly encourages the innovation and cooperation of the whole society through the opening and cooperation of source code. Of course, there will be a lot of problems and challenges in the application of blockchain in finance. This paper also thinks about the specific application

the working principle of blockchain technology is not difficult to understand. If we focus on the application research of specific blockchain technology, we can find that the working principle of this blockchain technology is ubiquitous.

7. Because blockchain is characterized by "decentralized, trustworthy and independent value"
for example, two people who don't know each other can check whether they can be trusted or not through the historical bookkeeping function of blockchain
if they can be trusted, transfer transactions can be generated directly instead of through the bank or payment platform

8. I have been paying close attention to the blockchain economy recently. You can come to the blockchain news network to learn about the latest market. It provides proct information of digital currency, blockchain, bitcoin and other popular digital currencies. Recently, I chose bitcoin to pay attention to market changes. It is very helpful for me.
