Multi party usage of blockchain
I have seen your question. In which aspects can blockchain be applied? Below by the small series to answer for you
bitcoin is the first specific application of blockchain. It was proposed in a paper by one person or a group of people in 2008. Bitcoin uses blockchain to send digital messages to bitcoin, and the name of bitcoin is bitcoin, without the intervention of a third party middleman
However, bitcoin is not the only application of blockchain, as follows:
1. Financial field: the application of blockchain technology in the financial instry can eliminate the third-party intermediary link, realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment
2. Internet of things and logistics: blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management
3. Public service: blockchain is closely related to people's proction and life in public management, energy, transportation and other fields, but the centralization of these fields also brings some problems, which can be transformed by blockchain
4. In the field of digital right: through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership
5. In the field of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs. Through the application of smart contract, there is no need for the applicant to apply or the insurance company to approve. As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized
6. Public welfare field: the data stored on the blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision
the above is for your reference only, hope you can adopt it, thank you
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.
