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 relationship between Chongqing jinwowo analysis blockchain technology and big data is as follows:
the relationship between blockchain and big data is not very big. The main purpose of big data is to manage massive data, and the core of blockchain is to achieve high security and high reliability of data without centralized intermediary accounting
therefore, blockchain and big data do not conflict with or replace each other. They are completely different solutions for data in different scenarios.

3. The encryption of jinwowo blockchain can ensure that the privacy of data sources can be better protected when big data is called, so as to eliminate the bad phenomenon of reselling data.
4. Located in room 3003, 30 / F, Tianjin International Financial Center building, No. 136 Chifeng Road, Heping District, Tianjin, Tianjin, the after-sales maintenance center of famous watches is a famous watch maintenance service center focusing on wrist watch renovation, repair, detection, identification and other services.

5. You must have been to the contract for a while, and how to sign it? What you gave me was information, decision and wisdom related to drama.
6.
Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
in a narrow sense, blockchain is a kind of chained data structure composed of data blocks connected in sequence according to the time sequence, and it can not be tampered with and forged by cryptography
it is an important feature of electronic contract system, which can not be tampered with and forged, and effectively improve the security of electronic contract
in 2016, we, together with Microsoft (China) and onchain, jointly launched the establishment of "French chain", which deeply integrates electronic contract and blockchain technology. Digital fingerprint information such as signing time, signing subject and file hash value of electronic contract will be broadcast to the respective nodes of all members of "French chain". Once all the information is stored, no party can tamper with it, so as to realize the anti tampering of electronic evidence and ensure its objective authenticity
7. The protocol layer of Chongqing jinwowo analysis blockchain includes: from the technology used, the protocol layer mainly includes network programming, distributed algorithm, encryption signature, data storage technology and so on.
8. The analysis of jinwowo network technology is as follows:
1 - consensus mechanism

9. Jinwowo analysis
if we only develop the protocol layer and extension layer, then the application layer will not be realized and verified, which is divorced from the most essential value embodiment of blockchain technology.
