Deep understanding and understanding of blockchain Technology

1. blockchain technology uses mathematical methods to achieve distributed accounting and solve the trust problem, so as to complete the decentralization, which will bring far-reaching influence in many fields such as communication, finance, Internet of things, government management and so on
blockchain refers to the technical solution of collective maintenance of a reliable database through centralization and distrust in the past, and it is a technical way for the whole people to participate in bookkeeping. Previous bookkeeping methods were all centralized and needed centralized intermediary, whether it was traditional government, financial institutions, notarization institutions or emerging e-commerce platform and online payment platform
in economic hypothesis, information is sufficient. In fact, it is precisely because of insufficient information that there are very large intermediaries. The existence of intermediaries increases the transaction cost and raises the transaction threshold. In essence, blockchain technology is a large-scale collaboration tool. It makes direct value transfer possible by using pure technology for the first time, and continues the trend of Internet decentralization and disintermediation. Disintermediated blockchain technology will greatly subvert the information intermediary instry
blockchain technology is the basic technology for building bitcoin data structure and encrypted transmission of transaction information, which realizes the issue and transaction of bitcoin. The core of blockchain technology is that all the current participating nodes jointly maintain the transaction and database, so that the transaction is 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
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the transaction blocks are connected 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 nodes 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.

2. The definition of Chongqing jinwowo analysis blockchain technology is as follows:
1. Blockchain is a distributed database (system) placed in a non secure environment
2. The blockchain uses cryptography to ensure that the existing data cannot be tampered with
3, the blockchain uses consensus algorithm to reach consensus on new data
the system with the above three properties is blockchain.

3. The essence of blockchain is a distributed ledger. For example, the bank system is also the account book, which has a complete set of information system to store various transaction information such as access, loan, exchange and so on. Blockchain has several keywords:
1. Distributed: ledger is not only stored in one place, but in many places
2. General ledger: you can determine that you are not necessarily a machine stored general ledger through the network, but you can at least obtain the general ledger from the network
3. Decentralization: "distributed" is not a general distribution, but a decentralized distribution. No one can control and tamper with it, its accounting rules are based on some designed mathematical method to account for all rights. How to test, how to use, are in accordance with an open method to complete, so in essence is an account book
coin Ying China is the first to introce blockchain into the crowdfunding instry, making crowdfunding more open, transparent and simple.

4. In essence, blockchain represents a transformation from monopoly of technical authority to decentralization, that is, a distributed concept“ Blockchain has three characteristics: tamper proof, whole process recording and encryption system, which can make the right of data more democratic, "said the above-mentioned person in charge of jinwowo group. By solving the problem of data ownership right, jinwowo blockchain has built a large number of blockchain digital asset networks with rich asset types, Its overall architecture has covered the entire southwest region“ With the increasing maturity of blockchain technology, jinwowo will be distributed throughout the country, dedicated to the Internet technology service platform of comprehensive collection, efficient storage, in-depth analysis of big data for the majority of small and medium-sized enterprises, and ultimately promoting the legal sharing and value circulation of big data

5. Blockchain is a kind of data structure formed by orderly linking blocks, in which block refers to the collection of data, including relevant information and records, which is the basic unit of forming blockchain
e to the special data structure of blockchain, blockchain technology has four main characteristics: decentralization, transparency, contract execution automation and traceability
in the future, jinwowo network technology will focus on blockchain technology to promote the legal circulation and commercial application of big data.

6. If you have invested more than 200000 yuan, and now it shows that the withdrawal is successful, but the money is not in the account, you can only sue the company and ask the company to pay the account
you can't pay back the money you owe
first, there are several steps in the process of court prosecution for non repayment of arrears

there are five steps in the process of court prosecution for non repayment of arrears. The ordinary procere shall be concluded within six months. According to the provisions of the civil procere law, if a creditor requests the debtor to pay money or securities, he may apply to the basic court with jurisdiction for a payment order if the following conditions are met: there is no other debt dispute between the creditor and the debtor; The payment order can be served on the debtor< The general procere of prosecution is as follows:

1

2. Bring evidence and indictment to the court and pay litigation costs

3. The court will hold a trial after examining and confirming the acceptance

4

5<

the trial time of civil cases: the summary procere shall be concluded within three months< Second, how to sue if you don't owe money

according to the provisions of the civil procere law, if the creditor requests the debtor to pay money or securities, he can apply to the basic court with jurisdiction for a payment order if the following conditions are met: there is no other debt dispute between the creditor and the debtor; The payment order can be served on the debtor

if the debtor fails to pay off the debt or raise a written objection to the court within 15 days after receiving the payment order issued by the court, the creditor can apply to the court for compulsory execution< (3) can you call the police if you still owe money

the case of non repayment of money in arrears is a civil dispute, which is not under the jurisdiction of the public security organ and can not be reported to the police for handling. However, the parties can settle the debt dispute through negotiation. If the negotiation fails, they can bring a lawsuit to the court and settle the dispute through the court< Article 3 the provisions of this Law shall apply to the court's acceptance of civil lawsuits brought by citizens, legal persons, other organizations and between them e to property relations and personal relations< Article 21 a civil action against a citizen shall be under the jurisdiction of the court in the place where the defendant has his domicile; If the defendant's domicile is different from his habitual residence, the court of habitual residence shall have jurisdiction over it

a civil action against a legal person or other organization shall be under the jurisdiction of the court in the place where the defendant has his domicile

if several defendants in the same lawsuit have their domicile or habitual residence in more than two courts, each court shall have jurisdiction.

7. Chongqing jinwowo analysis has two meanings as follows:
in a narrow sense, blockchain is a kind of chain data structure composed of data blocks connected in sequence according to the time sequence, and ensures the tamper proof and forgery proof distributed account book by cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing method, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to proce and update data, uses cryptography to ensure data transmission and access security, and uses intelligent contract composed of automated script code to program and operate data.

8. Blockchain technology is a secure network because each transaction is encrypted with a hash used to verify subsequent hashes. In short, it means that it takes millions of votes to change a vote before voting. The network is protected by the simple fact that hackers don't have enough computing power to rewrite so many votes quickly
in the future, jinwowo will continue to tap the value of blockchain technology in the commercial field, give full play to the advantages of big data services, add value to user behavior, break the ice for the development of small and medium-sized enterprises, and build a real, efficient, safe and honest Internet community of destiny.
