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. At present, there are four main types of consensus mechanisms: pow, POS, dpos, pool
1. POW workload proof, which is familiar with mining, calculates a random number that meets the rules through and or operation, that is, obtains the bookkeeping right, sends out the data that needs to be recorded in this round, and stores it together with other nodes in the whole network after verification
advantages: complete decentralization, free access of nodes
disadvantages: bitcoin has attracted most of the computing power in the world, and other blockchain applications using POW consensus mechanism are difficult to obtain the same computing power to ensure their own security; Mining causes a lot of waste of resources; The period of reaching consensus is long, which is not suitable for commercial application.
2. Proof of rights and interests of POS, a mechanism of upgrading consensus of pow; According to the token proportion and time of each node; It can rece the difficulty of mining in equal proportion, so as to speed up the speed of finding random numbers< Advantages: to a certain extent, it shortens the time to reach a consensus
disadvantages: mining is still needed, which does not solve the pain point of commercial application in essence
3. Dpos share authorization certification mechanism is similar to the voting of the board of directors, in which the coin holders cast a certain number of nodes to verify and account on their behalf
advantages: greatly rece the number of participating verification and accounting nodes, which can achieve second level consensus verification
disadvantages: the whole consensus mechanism still depends on token, and many commercial applications do not need token to exist
4. Pool verification pool, which is based on traditional distributed consistency technology and data verification mechanism; It is a consensus mechanism widely used in the instry chain at present.
advantages: it can work without token, and realizes second level consensus verification on the basis of mature distributed consistency algorithms (pasox and raft)
disadvantages: the degree of decentralization is not as good as that of bictin; The multi center business model is more suitable for multi-party participation
it has great advantages in using consensus mechanism to ensure data consistency (the consensus mechanism is first proposed by ripple, and the network transaction synchronization mechanism with data correctness priority. In the consensus network, no matter how the software code changes, if you can't reach a consensus, you can't enter the network, let alone fork)
- - - - - - - -
PS: a little black, although the consensus mechanism can absolutely ensure that there will be no hard bifurcation at any time. However, the disadvantage of this mechanism is obvious, that is, it is much longer than the current bitcoin network to reach a consensus with other nodes. In extreme cases, the consequences of disconnection in ripple consensus mechanism network are also very terrible
it is possible that one day after the power failure in your home, the whole system will no longer be able to reach a consensus with other rippled nodes (in fact, the consensus mechanism requires more than 80% of the nodes to acknowledge your data before your submission will be accepted by other nodes, otherwise it will be rejected by exclusive nodes), Even you can only empty all your 500 GB data and resynchronize to connect to other ripple nodes
so at present, the existing rippled end is not suitable for civil use (if it is commercial, the impact is relatively small. For example, RL's own rippled node is hosted in Amazon cloud data center. If it has no response for a long time, it can make high claims, and there is almost no break in that place except for large disasters). This is one of the aspects RL has always wanted to improve.

3. If we simplify the description of the operation process of the traditional notarial certificate, it should be like this: the parties apply for notarization - the notary office evaluates the application - confirms the authenticity and legality of the application items - makes, issues and delivers the notarial certificate. The running process of blockchain public certificate is similar. However, the operation mechanism behind the same operation process is not the same. The reason why the public certificate of blockchain is regarded as the Manifesto of the new environment of notarization is that it has made a subversive change to the traditional notarization certificate in the operation mechanism
01, the core operation mechanism of blockchain public certificate
the operation mechanism of blockchain public certificate is composed of two moles: "Notarization management" and "intelligent assistance". After the applicant submits the application, the blockchain notarization system relies on AI technology to audit the identity and information of the applicant. At the same time, the system will review the content of notarial evidence, and then issue a notarial certificate, at the same time on the chain filing. At the same time, the public certificate of blockchain has been formally formed, which immediately meets the online verification needs of users
the core of the operation mechanism of the notarial certificate of the blockchain lies in the application of the blockchain technology. No matter audio, video, photo or document, as long as it is stamped with a time stamp and then put on the chain, it can become an unchangeable and indestructible evidence document
the second important support in the operation mechanism of the notarial certificate of blockchain is the application of artificial intelligence. The application of this technology greatly saves the applicant's application and waiting time, and also greatly improves the speed and accuracy of the notarial office's document confirmation, eliminating the time delay of manual confirmation and possible operational errors<
02, analysis of the characteristics of the operation mechanism of the notarial certificate of blockchain
through the detailed disassembly of the operation mechanism diagram of the notarial certificate of blockchain, it is not difficult to find that compared with the operation mechanism of the traditional notarial certificate, the operation mechanism of the notarial certificate of blockchain has many noteworthy characteristics
the first is synchronization. In the process of generating the public certificate of blockchain, the actions of the applicant and the notary organization are almost synchronous, and the applicant's application and the notary organization's examination, certificate preparation and certificate issuance are almost synchronous. However, in traditional notarization, there is a time interval between the actions of all parties, which is prone to usurpation. Moreover, e to manual operation, a large amount of time cost will be generated, It further causes the delay of the process. The actions of all parties of blockchain notarization are synchronized online, and the action traces and data are generated instantaneously, thus recing the possibility of tampering and ensuring the authenticity and judicial effect of data files
the second is interactivity. In the process of generating the public certificate of blockchain, the actions of the applicant and the notarization institution are interactive - the applicant submits the application, the notarization institution's artificial intelligence audit, the certificate preparation, the certificate issuance, the data archiving, and the applicant's query are carried out alternately. Different from the traditional notarization, the applicant is more in a passive waiting state after submitting the application, which reces the participation of the applicant
dynamic again. In the process of generating the public certificate of blockchain, the evidence file is a dynamic generation process. The process of applying for the notarial certificate is the process of generating the notarial evidence, and this process itself is a part of the notarial certificate. The traditional notarization is that before the notarization, the evidence documents have been basically finalized. What the notary office does is just a process of confirmation and seal, and the dispute prevention function of notarization is weakened
it is precisely because the operation mechanism of the block chain notarial certificate is quite different from that of the traditional notarial certificate, which determines its absolute advantage over the traditional notarial certificate. On the one hand, it meets the people's requirements for efficiency in the digital age; On the other hand, it also strengthens the authenticity and legal validity of notarial documents. Its interactive feature adapts to the Internet era thinking of emphasizing interaction, which makes all parties involved in notarization enter a positive interactive state. Finally, the dynamic nature of the generation of the public certificate of the blockchain greatly gives play to the initiative of the notary organization, rather than passively confirming the existing evidence documents, which can give full play to the original preventive function of the notary.

4. Generally speaking, blockchain = block + chain. Block refers to the form of data, which is stored in the form of block (using higher-level encryption technology, which is difficult to tamper with). Chain is distributed storage technology. After block information is stored on the chain, distributed storage is carried out, which is linked with each other, and it is invalid to modify a single node
using blockchain technology, we can trace the source of food safety. This is an application scenario where blockchain technology is easy to implement and the technology is more mature. There are many procts that can be applied, including common commodities, high and low value-added procts
blockchain technology can improve mutual distrust, effectively improve proction relations, make it more transparent and digitally present traceability results
I'm going to develop the blockchain system. My friend introced Guangzhou Xuanling Network Technology Co., Ltd., which is a company engaged in software development and blockchain system development. Their development cases are not bad, involving a lot of business content, and the team strength is good. I feel the working atmosphere of this kind of company is comfortable, and I hope I can meet a good team.

5. By using blockchain, food companies can more quickly trace back to the source of food problems. This can not only help rece consumer risk, provide security, but also rece financial losses through targeted recall.
6. From 2009 to now, blockchain technology has developed from blockchain 1.0 era to blockchain 3.0 era, from the special technology of digital currency to the open technology of social field. With the promotion of the 13th five year plan for national informatization and the national big data strategy, the deep integration of blockchain and real economy is becoming the general trend
as China's agricultural instry has been facing many problems such as highly dispersed operators and long instrial chain, there are many obstacles on the road of transformation and upgrading. The blockchain has the point-to-point trust under the distributed cooperation, and the tamperable records can just solve many pain points in the uplink of agricultural procts, eliminate the information asymmetry to the greatest extent, improve the information transparency and timely response ability of the whole instrial chain, and realize the value-added of the whole instry. Therefore, blockchain technology is entering the field of agricultural procts proction and circulation, and is profoundly transforming China's agriculture
recently, China's first white paper on agricultural blockchain was released by China rural network. Through analyzing the actual case of China rural network's efficient integration of proction end and sales end by using Internet of things and blockchain technology, it is confirmed that the application of blockchain in agricultural instry is not simply to make the traditional offline process online, but to empower and enhance the efficiency of the instry
SUN Wei, CEO of China rural power grid, interprets the methodology of blockchain
as a representative enterprise of B2B e-commerce of agricultural procts in China, the core transaction category of China rural power grid is silk, with an annual transaction volume of several billion yuan. However, the upstream proction monomer of silk instry is small and scattered, the instrial chain is long and inefficient, the transaction cost is too high, and the buyer and seller will often break the contract artificially
China rural power grid blockchain + cocoon and silk instry supply chain
through blockchain Distributed Accounting and tamper proof technology, China rural power grid can present the information of buyers and sellers to upstream and downstream parties and relevant third parties openly and transparently, and the defaulter will be abandoned by the instry, thus establishing a positive reputation ecology through mutual chain, and letting good currency drive out bad currency
at present, the agricultural blockchain platform of China rural power grid has achieved success in the first stage, which can not only reshape the trust relationship between all parties, but also significantly improve the transaction efficiency and rece the transaction cost
generally speaking, the instry generally believes that blockchain will be used in the Internet of things, agricultural procts traceability, rural finance and other six fields
1 Internet of things
the combination of Internet of things and blockchain will enable Internet of things devices to achieve self-management and maintenance, saving the high maintenance cost of cloud control as the center
2 big data
blockchain technology has point-to-point trust, and tamperable records will become an excellent way to solve the problem of data authenticity and effectiveness
3 quality and safety traceability
the agricultural procts traceability system based on blockchain technology, all data can not be tampered with, making the information more transparent, true and accurate
4 rural finance
the open and tamperable nature of blockchain technology makes it possible for decentralized trust mechanism. When applying for loans, it is no longer dependent on banks, credit reference companies and other intermediary institutions to provide credit certificates. The lending institutions can obtain the corresponding information data of the blockchain
5 agricultural insurance
blockchain technology can improve the protection of agricultural intellectual property rights and the transaction of agricultural property rights, and greatly simplify the process of agricultural insurance. At the same time, smart contract will also make agricultural insurance payment more intelligent
6 supply chain
e to the openness and transparency of data among all parties, a complete and smooth information flow is formed in the whole supply chain, which helps to improve the efficiency of supply chain management. The characteristics of non tampering data and transaction traceability can also eliminate the problem of fake and inferior procts in the process of proct circulation in the supply chain
in fact, some powerful agricultural enterprises have been aware of the opportunities of blockchain and have made an early layout to explore.

7. The value of blockchain lies in safety, and the value of blockchain agriculture is for food safety, and these data have a very important reference role for the reproction of agricultural procts
with the development of value oriented agriculture, precision agriculture and central agricultural system, this kind of blockchain technology will promote the continuous development of the agricultural instry, and its technology can also bring more jobs
blockchain agriculture has existed for a long time, but some places are not mature enough, especially traceability. However, a dmtc agricultural traceability project was launched this year to fill the gap
in terms of data collection, through the application of artificial intelligence and Internet of things technology, it runs through the whole agricultural ecological chain. During agricultural proction, it automatically records the proction environment data and proction process data of agricultural procts, when agricultural procts are transported, it automatically records the transportation data, and when selling, dmtc terminal connects with intelligent micro supermarket to collect consumer behavior data, Through the popularization of intelligent micro supermarket, terminals are all over the living quarters, collecting rich data for instrial development, and carrying the value transmission and information transmission of agricultural ecological chain more perfectly
