1. Distributed ledger Technology
2. In essence, jinwowo thinks that blockchain technology mainly includes the following points:
1. Data storage: breaking the big data monopoly and promoting the growth of big data
2. Data analysis: providing detailed data reports and helping enterprises operate accurately
3. Data tracking: tracing the proct service process and ensuring the integrity image of enterprises
4 Data security: stop illegal data reselling and reshape data circulation rules

3. 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.

4. 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.

5. 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
6. The analysis of jinwowo network is as follows:
blockchain technology is essentially a kind of database technology, specifically a kind of account book technology
the account book records the asset changes and transactions of one or more accounts. In fact, it is a kind of database with the simplest structure. The daily accounts we usually record in the small account book and the statements sent by the bank are typical account books.

7. Chongqing jinwowo: blockchain technology is essentially a decentralized distributed database. It uses multiple computing nodes in the network to participate in data calculation and recording, and mutually verify the effectiveness of their information. It is characterized by decentralization, consensus mechanism, high transparency, and no need to rely on trust.

analysis
the essence of blockchain
technology is as follows:
blockchain is essentially a value based on P2P
transmission protocol
, we can not only see P2P, but not value transmission
similarly, we can not only see the value transmission, but also the underlying technology of blockchain.

9. 1. Data blockchain is an important concept in the bitcoin financial system. It records the transaction data of the whole bitcoin network, and these data are shared by all bitcoin nodes. Through the data block, we can query the history of each bitcoin transaction
2. Example:
Party A, Party B and Party C. all funds of Party A and Party B are kept by Party C. Moreover, each capital transaction should be recorded by C. Now suppose that Party A and Party B each have one million yuan in their custody. Then:
If Party A spends 80000 yuan to Party B, then Party C will subtract 80000 yuan from the account book and increase 80000 yuan from Party B
If Party B returns 50000 yuan to Party A, Party C will add 50000 yuan to Party A's account book and subtract 50000 yuan from Party B's account book
If Party A spends 50000 yuan to Party B, then Party C subtracts 50000 yuan from the account book and adds 50000 yuan to the account book
3. The function of data blockchain is similar to that of C's account book, which records the ownership of bitcoin and the transaction of bitcoin. But this "account book" is recorded by every bitcoin miner's mining software on the network. If a bitcoin transaction is confirmed by the data blockchain, the relevant information will be recorded in the data blockchain. Bitcoin's "account book" is called data blockchain. All the data blockchains on the network constitute the distributed network database system of bitcoin
4. The essence of data blockchain technology is a decentralized and distributed data storage, transmission and proof method, which replaces the dependence of the Internet on the central server with data blocks, so that all data changes or transactions are recorded in a cloud system. In theory, it realizes the self proof of data in data transmission, This kind of point-to-point verification will proce a "basic protocol", which is a new form of distributed artificial intelligence. It will establish a new interface and sharing interface between human brain intelligence and machine intelligence.
