Blockchain and quality inspection

1. blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
blockchain is an important concept of bitcoin, which is essentially a decentralized database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
let's talk about the social or economic significance of blockchain. In fact, many of the previous technologies were devoted to "proctivity". For example, artificial intelligence is a kind of progress in proctivity. The blockchain, which has greatly improved the proction relations, is committed to the proction relations. So why do you say that
because the so-called proction relationship is actually how to do business between people and business partners. And these things, originally, are in the cognitive process between people, and there is no special program to program or quantify it
for example, if you and I are good friends now, we can do business. If someone stirs up our relationship and we are not good friends, we will not do business. Even if we can make money in business, we will not do business because there is no trust between us
as for blockchain, it is actually because the data is authenticated by all nodes and backed up at the same time, so my data is as real as possible and can't be tampered with. In this case, if you believe my data, you can make a program on this basis, and then use the data to make what kind of business contract, what kind of service, what kind of service, and what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, etc This "proction relationship" of commercial cooperation is programmed. In this way, we believe in the data and the program compiled by the algorithm. Because you believe in the data and the program, you can develop all kinds of apps in the program. These apps are the proction relations and what business to do. This is: blockchain is actually a reconstruction of "proction relationship".

2. From an academic point of view, blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is essentially a decentralized database
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry
future development and application scenarios of blockchain
1. Digital identity
many people will encounter the dilemma of "proving that my grandmother is an alt" and "my mother is my mother" when they open various certificates. With blockchain, they will never have to worry about it again. It turns out that our birth certificate, real estate certificate, marriage certificate and so on need a central node for everyone to recognize. Once transnational, contracts and certificates may become invalid because of the lack of a global central node
the tamper proof feature of blockchain technology has fundamentally changed this situation. Our birth certificate, real estate certificate and marriage certificate can be notarized on the blockchain and become something trusted by the whole world. Of course, it can also easily prove that "my grandmother is an alt" and "my mother is my mother"
2. Health care
in short, it is to use blockchain to establish a general record repository with time stamp, so as to achieve the purpose of extracting data information from different databases
3. Travel consumption
when we travel, we often use Ctrip, meituan and other apps to find and place orders for hotels and other services, and each platform gets a commission from them. The application of blockchain is to remove middlemen and create a secure and decentralized way for service providers and customers, so as to achieve the purpose of direct connection and transaction
4. More convenient transaction
blockchain can make payment and transaction more efficient and convenient. The blockchain platform allows users to create smart contracts that become active when certain conditions are met, which means that automatic payment can be released when both parties agree to meet their conditions
5. Strictly control the proct quality
if you buy an apple, under the blockchain technology, you can know the whole process from the proction of fruit farmers to the circulation. Among them, there are government regulatory information, professional testing data, quality inspection data of enterprises and so on. The smart supply chain will make the food we eat and the goods we use safer and more reassuring
6. Art of property rights protection
the creator puts his works on the blockchain. Once someone uses his works, he will know immediately. The corresponding royalty will also be automatically paid to the creator. Blockchain technology not only protects right, but also helps creators sell their works to consumers more directly without the assistance of distribution companies.

- yinlian answer:

blockchain can realize the traceability and non tampering of data, because it is based on the distributed database established by cryptographic links, thus forming non tamperable data sources. Therefore, in the whole process of procts from proction to circulation, complete information records can be achieved, and comprehensive data information can be provided for regulatory authorities, so that they can more efficiently complete proct quality inspection and data interconnection and sharing. In this process, blockchain can solve four problems:

first, information can not be tampered, consensus can be reached and trust can be built. In the network node composed of each participant, data records are formed in the business process, and the information of proct logistics, warehousing and proction, including raw material source, processing and assembly, is stored in the blockchain network to provide data information of each link for regulatory departments, cooperative enterprises or institutions

Second, the process is open and transparent. In the process of business process, the proct's anti-counterfeiting and circulation can be realized by implanting an identification chip into the proct and registering it on the blockchain, so that it can have a digital identity, and then record all the information of the digital identity, such as source and flow, through the account book maintained jointly, so as to achieve the verification effect

Third, save cost and improve efficiency. Under the condition of confidentiality, the data records on the blockchain are stored, transmitted, verified and analyzed by the regulatory department, and transferred among different departments, so as to achieve unified voucher, whole process record and enterprise credit reference, which can effectively solve the problems of multi-party participation, information fragmentation and repeated audit in circulation

Fourthly, information sharing. The circulation of enterprise proct certification depends on the interconnection of public data resources among departments and institutions such as commerce, customs, quality inspection, instry and commerce, banking, etc. under the review environment of blockchain construction, all departments can obtain information synchronously, establish credit evaluation mechanism based on supply chain, and organically connect various supply chain platforms, so as to improve the credit rating, credit record, risk warning, risk management, etc Information disclosure and sharing of illegal and dishonest behavior

the disadvantages of traditional anti-counterfeiting traceability are very obvious, and anti-counterfeiting traceability has always been an important scenario in blockchain application, such as yinlian, which also starts from the anti-counterfeiting traceability scenario, hoping to build a commercial blockchain

compared with the traditional centralized anti-counterfeiting Traceability Technology, yinlian uses the underlying technology of blockchain, and the merchants proce their own anti-counterfeiting codes to remove the trust problem of cheating by the intermediate anti-counterfeiting merchants. The main process is as follows:

5. New technology is born to overthrow tradition! The law of human competition! Traditional instries do not realize how to start transformation! Of course, transformation is as painful as cutting meat

6. It depends on whether you invest. If you don't invest, you can make money by checking in every day. If you invest in the miner, the income will be higher.

7. Pout your head.

8. The reason why blockchain is deceiving is that many funds and air coins are under the banner of blockchain to recruit people to "cut leeks" to cheat money. Therefore, if you want to make investment, you should be careful of this. If you just want to know, I will some information I found to you. The following content comes from the network and my personal opinions, so it is only for your reference< The br / > Bobbi block is actually a panoramic life service application of block chaining, which applies block chain's underlying technology, artificial intelligence technology and panoramic VR space technology to build block chain ecosystem. It can be used for personal safety wallet tools (aggregating UnionPay, Alipay, WeChat payment, PayPal, and bank card payment). You can also set conditions for the other party to receive
for enterprises or groups, they can make use of the Bobbi panoramic blockchain as an intelligent ERP management system, put the enterprise's information and services into the panoramic space, and display their blockchain encrypted procts in the panoramic block. They can also establish their own blockchain distribution system through the intelligent contract, so as to truly realize the integrated operation of proct promotion and drainage, user experience and authentic proct sales
let's talk about my personal opinion. In recent years, blockchain has a trend of combining with different popular technologies, such as AI + blockchain, AI + blockchain and so on. This blockchain is panoramic technology + blockchain, so it is also an innovation to comply with the trend. Anyway, it seems that the concept of panoramic + blockchain is their idea, You can see the proct application or landing project corresponding to their concept. If the concept and proct application do not match, it is a gimmick. If not, it is not a fraud blockchain. The rest depends on your own understanding and judgment
very attentive answer, if you think it is helpful, please take it, thank you!

9. Chongqing jinwowo analyzes and solves problems in the following ways:
first of all, by using all data chains in the blockchain for prediction and analysis, the regulatory authorities can timely discover and prevent possible systemic risks. The decentralized characteristics of the blockchain can eliminate the information island in big data risk control, and improve risk control through information sharing

secondly, the distributed database of blockchain can improve the poor quality of big data risk control data, and solve the problems of data format diversification, data form fragmentation, lack of effective data and incomplete data content

finally, blockchain can prevent data leakage. Because the blockchain database is a decentralized database, any node's operation on data will be found by other nodes, thus strengthening the monitoring of data leakage.
