CCTV blockchain explanation
At the beginning of self-learning blockchain related knowledge, we can adopt the "bottom-up" method, that is, through reading books, reading white papers , we can check the information , and then summarize and connect these knowledge , and integrate them into a relatively complete knowledge system so I went to the bookstore and bought a of the Analects of Confucius. I read it from the beginning to the end and found that there were too many details and insights in it, which could not be transmitted through any interpretation. Actually, I spent a lot of time and read a lot of interpretation before. I really want to abandon the essence and pursue the end. I have to work hard it's the same in every field. When you don't understand it, you will have a kind of inexplicable fear of it, thinking that it is high and unattainable. In order to step into these fields quickly, you will look for a lot of so-called "interpretation" and "news" around it 2. technical perspective Basic Stage: 1. Blockchain Development Guide - author Shentu Qingchun: the author's research on the bottom layer of rendant bitcoin is very in-depth, and the explanation is very easy to understand 2. Blockchain technology guide - author Zou Jun: as the first domestic book to explain blockchain from a technical perspective, it is worth reading. Since its publication in 2016, it has been consistently evaluated well 3. Principles, design and application of blockchain by Yang Baohua and Chen Chang: as the CTO of Zhigui, Chen Chang remembers that the previous ink chain was based on hyperledger fabric, so this book has a thorough explanation of hyperledger related open source procts 3. Blockchain world is divided into two parts. The first part comprehensively reviews the birth, growth and graal development of blockchain in 2008 through full and accurate information, introces in detail the originality of blockchain technology, the scientific mechanism and the artistic logic, and introces the application characteristics of blockchain through more than ten instry scenarios such as finance, anti-counterfeiting and medical treatment. In the second part, combined with the spirit of G20 summit and the 13th five year plan, the author explores the combination of blockchain and digital economy, as well as the author's views and suggestions on the development trend of the instry
blockchain is actually two words, block and chain. Every bill is a block, which is linked together to form a blockchain.
first, at the beginning of bitcoin's operation, Xiaoming was given 200 yuan, and it was stipulated that whoever recorded the account first could get 10 yuan (this is the consensus mechanism, which encourages everyone to agree to do the same thing), Then give you a lot of blank bills, once a transaction occurs, you can fight for bookkeeping
1 one day, Xiao Ming gave Li Si 100 yuan (that's the deal). Then Xiao Ming could roar in the crowd and I gave Li Si 100 yuan (and sign his name). When you hear this, you can fight for bookkeeping.
2 because Wang Wu remembers quickly, he yells in the group when he finishes it first, and I remember well. This is Wang Wu, and he sends the bill to others. Wang Wu remembers very well, and there is no mistake after confirmation (Li Si signed his name), so Wang Wu gets a reward of 10 yuan, Then everyone put the bill on the last page of their books& lt; There can be multiple transactions at a time & gt
3 Wang Wu likes the glory of the king. He always likes a hero, demacia, but it costs 25 yuan, but Wang Wu only costs 10 yuan, which is obviously not enough. Wang Wu starts to think that I can keep my own account. Anyway, I can't see anything from the account book. Soon, Wang Wu got another chance to keep accounts. Besides keeping good records of other accounts, Wang Wu added one. Wang Wu gave Tencent 25 and then announced it in the group
4 while Wang Wu was waiting for demacia, Li Si carefully looked at the bill and found that it was all his own signature, no problem. However, Li Si found that Wang Wu had only 10 yuan to pay for the bill, so he refused. Similarly, everyone refused
5 Wang Wu's plan failed at the cost of wasting a lot of energy without rewards
the above basically explains the process of regional chain,
is the above explanation clear? Do not understand the place, you go to ask, lieyun finance it
blockchain is a decentralized distributed ledger database . The advantage of this distributed ledger is that buyers and sellers can trade directly without any intermediary. Everyone has a backup, even if you lose this, it will not be affected
{rrrrrrr}
extended data:
blockchain application field
1, financial field
blockchain has potential huge application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields. The application of blockchain technology in the financial instry can save the third-party intermediary link and realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment
2. The 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. This field is considered as a promising application direction of blockchain
3. The data stored on the public welfare field
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
4. In the field of insurance
in terms 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
using ordinary computer CPU does carry out bitcoin mining. Because bitcoin mining has formed a huge instry all over the world, ordinary computer is difficult to dig bitcoin. You need to buy expensive and professional bitcoin ASIC mining machine and join bitcoin miners' organization to dig bitcoin, that is, join the mine to dig Mining
bitcoin mining machine market has a high threshold. It is suggested that new players who want to dig for gold should be cautious.
at present, bitcoin mining needs professional ASIC mining machine. For example, Avalon mining machine, the mainstream of the market, is said that Avalon's fourth generation 28nm process chip, that is, chip flow, is expected to focus on the fifth generation 16nm process chip
