1. Distributed ledger Technology
2. blockchain is a new application mode of computer technology, such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and so on. As an important concept of bitcoin, blockchain is essentially 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, which is used to verify the validity of the information and generate the next block
this is a passage in Alibaba's documentary dreamer. When ps: is repeated many times, it can explain the term "third parties" very well. This is also the beginning of Taobao and Alipay's birth. In other words, at that time, Ali was forced to act as a "third party" because no company could play such a role, so Ali became a center of trust. Businesses and users chose to give money to Ali because of "trust". But what if Ali absconds with money (though impossible...) or if the financial operator has problems (after all, it's human...)? If only there was a machine or a "super system" to do these things! Today, more than ten years after the replacement of Internet technology, blockchain appears in front of us, right! It's the super system;! A machine of trust
with blockchain, things start to change
traditional centralized mode:
decentralized mode under blockchain network:
in decentralized network, each user can be directly contacted without any third party's participation, and the transfer between users is like hand-in-hand cash, which is why bitcoin is called "e-cash"
well, now that a has transferred the money to B, who will charge the account? Alipay has helped me keep account of accounts, which will be unified in Alipay backstage system. In order to make all the transactions of the users recorded and the accounts are correct, Alipay will make great efforts to this end. Look at Alipay's initial
1000 bills per day. Artificial reconciliation is already very painful. With the volume of Alipay now, there are less than hundreds of thousands of bills per day, even if the system reconciliation is unavoidable, and it is necessary to pay the corresponding manpower and material resources to maintain this very complex revenue and expenditure clearing system. Having said so much, how does the blockchain reconcile? The answer is: no! There is no need for reconciliation and zero clearing in the blockchain network, because every node in the blockchain (a computer or a user) has its own account book, which is updated in real time. Any transaction in the blockchain network will be recorded in your own account book. Yes, you also have other people's accounts, But you don't know who this person is, because they all look like this:

this is the general content of popular science. If you want to know more about it, you can take a look at Nakamoto's paper and the official popular science video below
The price of a bitcoin soared from more than $20000 to $40000. This can not help but arouse my research interest, or simply understand what bitcoin is, what its mechanism looks like, and uncover its mystery. Therefore, after a simple search of some information and some understanding of the special currency, I sorted out the information on hand< (3) purpose: decentralize, rece risk
all servers in the distributed network can store and process data, and each server has equal status, which can store more data and has higher security<

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 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.

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.
