All blockchain technologies are interworking in the world
blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
blockchain is an important concept of bitcoin. In essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
extended data
according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:
1. The blockchain with the whole network open and without user authorization mechanism is called public chain
2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain
3. All the nodes in the network are in the hands of one organization, which is called private chain
alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain
blockchain features
1, decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain
2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention
4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously
Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
blockchain money making methods:
1. Promotion to earn commission
the method of blockchain is to first register the exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates a transaction, you will have a commission
2
currency speculation is like stock speculation. Currency speculation is the lowest threshold for blockchain to make money
3. mining
Mining in bitcoin is the process of bookkeeping. This process needs to be tackled. If you seize the opportunity of bookkeeping right, there will be a reward. The reward is bitcoin. This behavior is called "mining"
4
wallet is the infrastructure of the block chain, just like the "Alipay" or "WeChat payment" of the block chain. p>
development materials:
1. Blockchain is an important concept of bitcoin, which is essentially a decentralized database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
2. The blockchain was born from the bitcoin of Nakamoto Tsung. Since 2009, there have been various digital currencies similar to the bitcoin, which are all based on the public blockchain
On January 20, 2016, the digital currency seminar of the people's Bank of China announced that the research on digital currency has achieved phased results. The meeting affirmed the value of digital currency in recing the issuance of traditional currency, and indicated that the central bank was exploring the issue of digital currency. The expression of the digital currency seminar of the people's Bank of China has greatly enhanced the confidence of the digital currency instry. This is the first time that the five ministries and commissions of the people's Bank of China have expressed a clear attitude towards digital currency since they issued a notice on preventing bitcoin risks on December 5, 2013 blockchain network

Digital China is the first major development strategy explicitly put forward in the report of the 19th National Congress of the Communist Party of China. The application of digital technology represented by cloud computing, big data and mobile Internet is no longer limited to the economic field, but widely penetrated into all aspects of public services, social development and people's life, which requires macro coordination, overall control and integrated development
with the deepening of a new round of scientific and technological revolution and instrial change, the tide of digital economy in the world is unstoppable. The development of digital economy has become a global consensus, known as the key to the fourth instrial revolution
adhering to the connotation of the University of nice's world inclusive humanistic spirit, always embracing change, standing up to the tide, conforming to the development trend of the digital economy era, and integrating the essence of Chinese and Western cultural thinking, the University of nice's doctor of blockchain and digital economy management (DDE) came into being
based on this, we can enable the managers of digital economy instry to have global vision and global integration thinking, integrate knowledge, operate digital economy intelligently, promote the sustainable development of the instry, and contribute to the community of human destiny. Therefore, DDE project will cooperate with colleagues in the field of digital economy

- yinlian answer:
blockchain can realize the traceability and non tampering of data, because it is based on the distributed database established by cryptographic links, thus forming non tamperable data sources. Therefore, in the whole process of procts from proction to circulation, complete information records can be achieved, and comprehensive data information can be provided for regulatory authorities, so that they can more efficiently complete proct quality inspection and data interconnection and sharing. In this process, blockchain can solve four problems:
first, information can not be tampered, consensus can be reached and trust can be built. In the network node composed of each participant, data records are formed in the business process, and the information of proct logistics, warehousing and proction, including raw material source, processing and assembly, is stored in the blockchain network to provide data information of each link for regulatory departments, cooperative enterprises or institutions
Second, the process is open and transparent. In the process of business process, the proct's anti-counterfeiting and circulation can be realized by implanting an identification chip into the proct and registering it on the blockchain, so that it can have a digital identity, and then record all the information of the digital identity, such as source and flow, through the account book maintained jointly, so as to achieve the verification effect Third, save cost and improve efficiency. Under the condition of confidentiality, the data records on the blockchain are stored, transmitted, verified and analyzed by the regulatory department, and transferred among different departments, so as to achieve unified voucher, whole process record and enterprise credit reference, which can effectively solve the problems of multi-party participation, information fragmentation and repeated audit in circulation Fourthly, information sharing. The circulation of enterprise proct certification depends on the interconnection of public data resources among departments and institutions such as commerce, customs, quality inspection, instry and commerce, banking, etc. under the review environment of blockchain construction, all departments can obtain information synchronously, establish credit evaluation mechanism based on supply chain, and organically connect various supply chain platforms, so as to improve the credit rating, credit record, risk warning, risk management, etc Information disclosure and sharing of illegal and dishonest behaviorthe disadvantages of traditional anti-counterfeiting traceability are very obvious, and anti-counterfeiting traceability has always been an important scenario in blockchain application, such as yinlian, which also starts from the anti-counterfeiting traceability scenario, hoping to build a commercial blockchain
compared with the traditional centralized anti-counterfeiting Traceability Technology, yinlian uses the underlying technology of blockchain, and the merchants proce their own anti-counterfeiting codes to remove the trust problem of cheating by the intermediate anti-counterfeiting merchants. The main process is as follows:
first, if there is not much start-up capital in hand, how to raise funds to set up a company with a registered capital of 1 million yuan
Second, we are going to start business at home at the beginning, but we can't complete the instrial and commercial registration of family residence. What should we do< In fact, since March 1, 2014, the state has begun to adjust its policies and implement the system of subscription of registered capital. Even if there is no start-up capital, other methods can be used to register the company. In the new policy, the restrictions on the way, time limit and amount of capital contribution are cancelled. The purpose of the state's move is to encourage entrepreneurship. Even if you don't have any money, you can easily register a company with 1 million yuan in this way. In the future, when you make money, you can supplement the registered capital
What are the fees for registering a company in Shanghai, regardless of the registered capital? Zhihao has sorted out for you the expenses of business registration, seal engraving and tax registration certificate in the process of company registration, as well as the expenses of subsequent business tax declaration, taxpayer and registered address of the company
I. business registration fees. In the national policy, business registration does not need to spend money, free of charge
2. The cost of official seal engraving. A very important step to complete the instrial and commercial registration is to obtain the official seal. The cost of carving the official seal is 50 yuan / set, which is a necessary cost< Third, the cost of tax registration certificate. The fee is free< 4. Fees for Instry license and food hygiene license. If the company needs to apply for these certificates, there may be corresponding expenses< 5. The bank opens the basic account of the company. For bank account opening, the fee charged by each company may vary to a certain extent. The general fee is more than 500 yuan< 6. The cost of purchasing invoice. The company needs to buy tax cards, special printers, billing software and so on. The total cost is about 2000-3000 yuan< 7. If you need to apply for general taxpayer qualification and issue VAT invoice, the cost will be increased. If an enterprise is engaged in import and export trade, there are administrative charges when it goes through the import and export filing proceres, and the cost is about 2000 yuan.
8. If it is entrusted to an agent company, the cost of registering a million companies in Shanghai is not much, but in the process of registering a company, there may be a lot of cumbersome affairs to deal with, In this case, in fact, looking for an agent to complete the registration can save more time and energy. The total agent fee is about 500 yuan
simply speaking, the process of business registration in Shanghai is as follows:
check the name - register online - hand in the business establishment information - get the business license - engrave the seal - do the organization code certificate - do the tax registration certificate - open the basic account (taxpayer)
the detailed steps and cycle are as follows:
1. To approve a company name, it is better to submit 3-5 company names in the preferred order at a time to prevent plicate names. If it is submitted again, the approval time will be longer. The name of the company requires the company name, shareholder name, ID number and capital contribution ratio. 1-3 days
2. After the name is approved, fill in all the delivery materials, make an appointment, and submit the documents to the Administration for Instry and commerce; 7 days
3 and 7 days later, after obtaining the business license, we will handle the tax, code and stamp. 7 days to complete the documents
1. Network experience (the one with the most income in my part-time job at present)
many people don't understand how to make money from network experience. In fact, it's very simple. You can register and open an account, and then you can collect some pictures and texts online and publish them. I'm just carrying them. I don't need to think about what to write, just them all, More time may be spent looking for material. How to find, official account and other non network series can be, of course, many will decide that no original, no gains, never mind, you insist.
compared with the current income at the beginning,
it may be a few cents at the beginning. With the increase of the number and level, the income also increases. I have three accounts for more than a year, and now I have experienced the highest level of Dashen Lv2. With a fixed income of more than 10 yuan per day, plus red envelopes, good pen farming and other subsidies, I can add up to more than 1000 yuan a month. Before that, I had to punch in, I can earn more than 2000 yuan a month, but now it's less. Basically, I talk for more than an hour every day, and I send 5 articles to each number, with a total of about 15 articles. It's relatively easier<
the subsidy for clocking is gone
2. E-commerce platforms take orders
for goods taken on e-commerce platforms (mainly: Taobao, Jingdong, pinoo, etc.), sellers will give commissions or small gifts such as data lines, paper towels, umbrellas and so on. I usually add business cards shared by everyone in the group, and some of them will give you tasks, Accumulated for a period of time, there are fixed businesses looking for you. Now I have fixed those shops to do tasks every month to earn some small gifts and commissions. Generally, I earn about 100 yuan a month. If you have enough leisure, you can do more. A friend of mine, Bao Ma, said that he could earn more than 600 yuan a month with three titles. What leisure and perseverance he had
anyway, I can't stand the comparison of goods and screenshots operated by Xiao, which wastes my time. However, students and Baoma are the main force in the group. Generally, this is more suitable for idle people, but novices should also pay attention to fraud prevention. Generally, shops have margin and sales volume, and it's basically OK to shoot physical goods. Many businesses return immediately, and the seller is the vulnerable group
3, Taobao customer commission
many people do Taobao customers will establish a website or group to promote, I believe many people will be pulled into the coupon group, Business Internal group and so on, this is what they promote to earn commission. Ordinary people can not maintain the group, or help friends to buy or their own shopping to earn some commission, save money is more practical. I usually recommend procts that I think are good to my friends. It's OK to help them earn some commission, and it's also hard to earn a lot of pocket money to help friends, relatives and neighbors buy on their behalf
4. Information reading software
now many information apps have been launched to exchange points for money by reading articles. I have tried more than ten apps, and many one yuan tasks are easier to complete. Then I basically rely on apprentices to earn points to earn rewards. I can't earn much money by reading on my own every month. I have tried more than ten apps on four micro signals, and basically I earn rewards for apprentices, I earned more than 100 yuan in two days, no
