Application purpose of blockchain
what is distributed and decentralized? Take marriage registration as an example. In the past, when two people got married, they had to go to the Civil Affairs Bureau to go through the formalities, and then enter the information into the computer before they could finish the legal process. What if we use blockchain technology? As long as two people agree to get married, and then release a message in the circle of friends, the process of marriage is completed, and there is no need to go to the Civil Affairs Bureau. Your friends are common witnesses, they may be distributed all over the world, but their mobile phones will help you record the information and tell others who want to know
if you want to hide the marriage information, you used to just modify the records on the computer of the Civil Affairs Bureau, but now you have to modify the records on the mobile phones of all the people who know the truth at the same time. The more people who know the truth, the less likely they are to modify it, so it is an impossible task. This is distributed and decentralized
deepen the understanding
on the network, every once in a while, a block will be generated. This block is equivalent to a network logbook, which is used to record the relevant information that happened in a period of time. When the logbook is full, a new logbook will be generated. Once the information is recorded, all participants will be informed, and everyone's logbook will be updated synchronously
these logbooks are finally connected in series, which is blockchain technology. Because of the use of cryptography technology, if someone wants to tamper with the message unilaterally, through the verification of blockchain algorithm protection mechanism, if the time point is not right and the associated information is not right, other people will not update their own record book, and the information will be invalid
therefore, compared with the traditional information storage technology, blockchain technology is more secure, transparent and irreversible
concept differentiation
blockchain is not equal to bitcoin, it is just a kind of underlying technology invented to realize bitcoin as a digital currency. Blockchain can be applied to a wider range. In addition to digital currency, it can also be applied to P2P loan, global payment, micro finance, electronic payment, remittance and other financial aspects. It can also be applied to intellectual property, election, notarization and other aspects of people's livelihood.
China's blockchain instry ecology has initially taken shape, and the number of enterprises has increased rapidly. According to the white paper on China's blockchain instry in 2018 previously released by the information center of the Ministry of instry and information technology, as of the end of March 2018, the number of blockchain companies with blockchain business as the main business in China has exceeded 450, and the instry has initially taken shape
the Ministry of instry and information technology proposes that the blockchain instry is still in the initial stage, and the positive value of technology is graally emerging, but there are still risks that can not be ignored in the development process, such as challenges to the current system and norms, technical loopholes, etc. The Ministry of instry and information technology proposed that it will accelerate the innovation and application of blockchain technology, especially strengthen the improvement of computing capacity, storage capacity and integration penetration capacity, build a good instrial ecology, and promote the healthy development of blockchain instry
blockchain can improve transparency and rece the cost and risk of the whole supply chain. Through the blockchain, we can digitize the physical assets and create a decentralized and immutable transaction record, so that we can track all the relevant information that may take several weeks to obtain.
with the rise of blockchain technology, the encryption of blockchain technology can provide solutions for the protection of personal information. Blockchain technology can store personal information in a distributed way to avoid the security risks faced by a single server
and as one of the most ice breakers in the research of blockchain technology, jinwowo network technology has concted in-depth research and application of blockchain technology. Jinwowo's big data service based on blockchain can eliminate illegal data reselling and reestablish data circulation rules from four aspects of data storage, data analysis, data tracking and data security.
