Blockchain economic model

2. I'd like to know about blockchain. It's said that blockchain can create ten times the value of the Internet, so I'd like to ask you to use blockchain to create 1 million value for me. Anyway, it's just a small amount of money for blockchain.

3. The profit model of blockchain trading platform
1. Exchanges. Now there are 220 well-known transactions in the world, and about 2000 unknown ones
2. Mobile mining machine: the original mining machine, which costs money and energy, will be replaced by some online games, small videos and articles
3. Blockchain scenario Trading: the blockchain trading platform can be used not only in financial scenarios, but also in e-commerce trading scenarios, game mining scenarios

4. 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.

5. Positioning as "technology driven enterprise service platform", zhubajie has been exploring new development mode in the field of digital economy. A year ago, zhubajie network began to introce blockchain technology for service transactions
taking zhubajie.com platform as an example, blockchain technology has played a role in the field of service transaction, quietly providing strong technical empowerment for service transaction protection. In zhubajie, blockchain technology has helped many users provide service transaction protection and right protection.

Share from DTV: how does the blockchain of DTV make profits in the end:

1. Build a blockchain ecosystem

Why do start-ups join in blockchain public chain projects one after another? Because it's a great opportunity. Any enterprise has the opportunity to create an ecosystem that subverts the existing pattern with its own ideas and operations. In this system, the currency designated by the ecosystem owner will circulate

because start-ups hold a certain amount of money and reserve some money for enterprises to dig, and the total amount of money is fixed, the faster the flow speed of the ecosystem is, the greater the demand for money is. More transactions chase less money, and the currency is bound to appreciate, but this idea is based on the fact that the currency is irreplaceable

now many research groups are developing cross chain technology to connect blockchains in different fields, so as to achieve the free circulation of money flow and data flow, and finally go to the exchange

in this case, the impact of a chain of money shortage on the ecosystem may not be as simple as the classical monetary theory, and the money price is likely not to follow the simple relationship between supply and demand. Designers need to think about this from a macroeconomic perspective

this is also the most attractive part of blockchain project: everyone is likely to establish new rules in this new field and become the manager of Qu centralized system. By then, the owners of the blockchain will have the ability to control the economy of the whole field - selling or inhaling digital currency will have a huge impact on the instry

2. Providing services for enterprises

providing services for enterprises is the main profit model of blockchain projects at the present stage, and cloud storage security skeptics are likely to turn to traceable and tamper proof blockchain service providers to seek maximum data security

for example, a blockchain start-up operating a data sharing platform, its main business includes providing data storage and data transaction services for customers, thus charging service fees and handling charges

there are many domestic start-up companies operating such businesses, such as cloud nest, border intelligence, magic chain technology, etc. Each company has excellent technology, but to make a profit, it may have to work hard on the operation

today, Tencent cloud's tbaas has joined this field and can provide services covering finance, supply chain, Internet of things, medical and other fields. It is believed that the competition and expansion of customers will become more difficult in the future

3. Smart contract participates in profit making

smart contract is like a contract that can be executed automatically. The validity of the contract is judged and enforced by machines instead of people. Its essence is still a piece of code, but the traceability and non tampering characteristics of blockchain can ensure that this piece of code runs automatically under the non trust mechanism. Blockchain is the precondition of smart contract operation

in practice, there are many opportunities for profit making through smart contracts, and smart contracts can solve these problems in a non black box way

in the running process of the program, the smart contract performs audit, classification information and other operations, which eliminates the interference of middlemen, and the record will not be artificially damaged, and the font on the file will not be blurred for a long time

but to some extent, the operators of smart contracts themselves become middlemen, and they automatically collect and pay audit fees through smart contracts. This kind of special intermediary service saves a lot of costs for customers, and its essence is realized by improving efficiency

4. Operation of special service driven system

many enterprises have their own exclusive fields in building blockchain community. Take the neurogenomics project led by geneticist church as an example. After enjoying the gene sequencing service provided by neurola, consumers can not pay in the form of legal money, but have to exchange legal money into the token issued by neurola

as more people exchange legal money for this token, nebula will successfully build a blockchain platform with gene data as the core, and after that, it will better carry out precision medical services

generally speaking, this mode relies on the actual technology, makes profits from offline services at the beginning of the project, and converts the legal money in the income into token in the process of making profits. With the progress of the project, the platform can carry out more precision medical services with the help of the data obtained from the start mode, and its profit methods have become diversified, but the whole process will not be separated from the entity

in the whole process of enterprise operation, token is mainly used as incentive, and token appreciation is not a problem that geneticists should consider

The original purpose of project 1CO is to crowdfunding in the market through pre-sale service. In 2013, the early 1CO company appeared in the financial field, and then quickly detonated the entire digital money market, resulting in the rise of speculation

however, this storm came and went quickly. From 2013 to 2014 alone, many projects died in the speculation or were directly judged as fraud

according to Engadget data, 45.6% of the 902 crowdfunding based digital currencies have failed in 2017

Even so, there are still many survivors. These enterprises (including those that build the ecosystem) attach great importance to the role of token, and the appreciation of token will be calculated as part of the profits

In essence, it is similar to an enterprise operating both financial assets (token) and operating assets (service) to manage operating assets to make financial assets profitable. However, if the proportion of "financial assets" is too large, the risk will come uninvited

The foundation of sharing economy is to monitor the available resources and corresponding demands in real time and make adjustments to maximize the utilization of resources. For unicorns like airbnb, they have a mature management mode and stable cash flow. They try blockchain because blockchain technology can bring more transparent, more efficient and fairer systems

this kind of enterprises use blockchain in the way of private chain or alliance chain. They don't need token to participate in circulation, and the nodes don't exist anonymously. They are interested in blockchain technology itself

with the blessing of blockchain technology, the manual input of ID information issued by the government will be transformed into the safe storage and verification of ID issued by the government. Customers and landlords can completely rely on the evaluation content. At the same time, the comments can be traced back to avoid the possibility of negative comments being deleted and the participation of the Navy

the profit model of airbnb and Tencent

7. What is blockchain? The explanation given by the network is that blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system. What are the characteristics? As for the characteristics of blockchain technology, combined with the definition of blockchain, jinwowo Group believes that blockchain should have these four characteristics: decentralized, trustless, collectively maintained and reliable database. And from the four features will be extended to another two features: open source, anonymity. If a system does not have these characteristics, it can not be regarded as an application based on blockchain technology.
