You can't cheat with blockchain technology

1. blockchain can be said to be a powerful high-tech tool to crack down on fake jadeite instry. Jiubao live broadcasting, as a live broadcasting platform for purchasing jadeite procts on behalf of the source, has used blockchain technology to open a precedent for fighting against counterfeiting in the jadeite instry. Jiubao live broadcasting is changing the traditional trading mode, from proction to trading, to match the real information of jadeite one by one. Distributed accounting is adopted from the beginning of raw material mining. Every link will be clearly recorded, and this record is open to consumers and businesses. Even if jadeite has not arrived at the designated place, people participating in this system can also check the status of jadeite. Through distributed bookkeeping, consensus and its tamper proof properties, the platform can solve the problem of one-to-one correspondence between electronic vouchers and physical objects, thus ensuring the authenticity of procts. Therefore, the introction of blockchain technology into reporting indicators does mean that transactions on the platform will be more open and transparent in the future.

2. A special database technology, which is based on elliptic curve digital signature algorithm in cryptography to achieve decentralized P2P system design. But the role of blockchain is not limited to bitcoin. Now, when people use the word "blockchain", sometimes it refers to data structure, sometimes it refers to database, sometimes it refers to database technology, but no matter what the meaning is, it has no inevitable connection with bitcoin

from the perspective of data: blockchain is a kind of distributed database. The "distributed" here is not only reflected in the distributed storage of data, but also reflected in the distributed records of data (that is, it is collectively maintained by system participants). In short, blockchain can realize distributed recording of global data information (which can be collectively recorded by system participants rather than centralized recording by a centralized organization) and distributed storage (which can be stored in all nodes participating in recording data rather than centralized storage in centralized organization nodes)

from the perspective of effect: blockchain can generate a set of time sequence, tamper proof and trustworthy database, which is decentralized storage and data security can be effectively guaranteed<

the working principle of blockchain technology

today's blockchain technology can be summarized as a technology to collectively maintain a reliable database through centralization and de trust in the past. In fact, blockchain technology is not a single and brand-new technology, but the result of the integration of a variety of existing technologies (such as encryption algorithm, P2P file transfer, etc.), which are cleverly combined with the database to form a new way of data recording, transmission, storage and presentation. In short, blockchain technology is a technology that everyone participates in recording and storing information. In the past, people entrusted the work of data recording and storage to the centralized organization, while the blockchain technology allows everyone in the system to participate in the data recording and storage. Under the distributed peer-to-peer network without central control point, blockchain technology uses the method of distributed collective operation to build a P2P self-organizing network. Through the complex verification mechanism, the blockchain database can maintain the integrity, continuity and consistency. Even if some participants commit fraud, the integrity of the blockchain cannot be changed, let alone tamper with the data in the blockchain

the source of blockchain technology principle can be summarized as a mathematical problem: Byzantine general problem. Byzantine general problem extends to Internet life, and its connotation can be summarized as: under the background of Internet, when we need to exchange value with unfamiliar opponents, how can we prevent people from being deceived and confused by malicious saboteurs, so as to make wrong decisions. The Byzantine general problem is further extended to the technical field. Its connotation can be summarized as: in the absence of trusted central nodes and trusted channels, how to reach a consensus among the nodes in the network. Blockchain technology solves the well-known Byzantine Generals Problem - it provides a way to create consensus networks without having to trust a single node<

Application of blockchain technology

blockchain technology overlaps three fields:
1, currency: issuance mechanism, distribution mechanism, adjustment mechanism
2, contract: equity, mutual insurance, right registration and transfer, smart contract, etc.
3, Governance: identity authentication, health management, notarization, judicial arbitration, decentralized autonomous organization, Voting, etc.

blockchain is like a "trust creating machine". What Bubi blockchain needs to do is a new technology and proct to realize real value circulation and make the Internet reach a new height

when it comes to blockchain technology, we have to mention bitcoin. Many people know that electronic currency bitcoin is not issued by a specific monetary institution, but generated by a large number of calculations of a specific algorithm. In fact, the core of real support for bitcoin is blockchain technology

How can invisible and intangible bitcoin operate through blockchain technology? The popular interpretation in the instry is that blockchain can be seen as a technical solution to collectively maintain reliable databases through "decentralization" and "distrust". Generally speaking, this technology can be understood as the technology of all participants in bookkeeping. In the past, people used a centralized server for bookkeeping. In the blockchain technology system, everyone can participate in bookkeeping and jointly identify the authenticity of records

"through this technology, even if there is no neutral third-party organization, the two sides who do not trust each other can cooperate. In short, blockchain is like a "trust creating machine."“ Blockchain technology is widely used in the era of big data. " At present, in addition to the field of Internet finance, blockchain technology has been applied in many fields and has shown great prospects

in addition, blockchain technology is also of great significance in law. Especially in the field of assets, whether it is physical assets such as real estate and automobile, or intangible assets such as health and reputation, we can use this technology to complete registration, transaction and tracking. It can be said that blockchain technology will be useful in any field of proction and life that lacks trust. "

blockchain technology concept stocks

it is recommended to pay attention to it manufacturers with blockchain technology and applications. We think that blockchain is more like a mechanism or technical solution. In the future, manufacturers who can combine this mechanism into different scenarios for promotion and application are expected to achieve subversive success. Blockchain technology can ensure that the data structure will not be tampered and forged, and has broad application prospects in the field of financial payment. Bubi blockchain has set up a special team around digital currency, focusing on the development trend of digital currency for a long time, and has set up a special team to carry out relevant work around the instry development demand of digital currency, including the research on blockchain technology.

We mainly apply blockchain technology to the field of electronic data distributed storage, including contract storage, e-mail storage, file storage, structured data storage, etc

the specific forms of electronic evidence in judicial practice are becoming more and more diversified, and the frequency and amount of electronic data are increasing significantly. Different types of electronic evidence have different forms of formation, but they are easy to die out, easy to tamper with, and highly dependent on technology. Compared with traditional physical evidence, it is more difficult to determine the authenticity, legitimacy, and relevance of electronic evidence through judicial review

in the whole life cycle of the generation, collection, transmission and storage of electronic data, blockchain technology can be used to protect electronic data, prevent tampering, and leave traces of data operation, so as to provide effective means for relevant institutions to review. Using blockchain technology to preserve electronic evidence, the electronic data that needs to be preserved is recorded in the form of transaction, stamped with time stamp, and recorded in the block, so as to complete the process of data preservation and preservation. In the process of data storage, multiple participant nodes witness together and maintain a distributed ledger, which greatly reces the possibility of data loss, tampering and attack. The combination of blockchain and electronic data storage can rece the cost of electronic data storage, facilitate electronic data collection and evidence identification, and improve the litigation efficiency in the field of judicial storage

4. When it comes to blockchain, we have to talk about bitcoin. Most people in the market begin to recognize bitcoin through its market influence, because bitcoin was born on the basis of blockchain technology. Blockchain is simply an innovative application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Applying this technology to the transaction of virtual currency can make each transaction proce a corresponding data block, so as to ensure the authenticity of information. The biggest advantage is that it cannot be forged, It solves the trust problem in data transaction environment

of course, as blockchain technology becomes more and more mature and stable, it will be more and more applied in various real instry business scenarios, including finance, social communication, Internet of things, e-commerce, games and securities trading, For example, our project of "intelligent system for ecological chain of structural hole investment and financing" is the first innovative application of this technology in the field of investment and financing. However, from the purely technical level, the main purpose of blockchain is to ensure the safety of data operation, which is the biggest advantage of this technology. So what is the relationship between blockchain technology and virtual currency? Take bitcoin as an example. Bitcoin is a virtual currency based on blockchain technology and proced through a large number of algorithms. Due to its special algorithm and the anti-counterfeiting function of blockchain technology, the total number of bitcoin will remain unchanged at 21 million. It is precisely because things are rare that bitcoin is loved by many people

so why are there a lot of virtual currency scams under the banner of blockchain in the market today? This is because these so-called innovative application companies of blockchain issue virtual currencies. Although they claim that the number of virtual currencies is very limited in the market promotion, and they can make investors earn a price difference by raising the price through currency speculation, in essence, the issuance of their virtual currencies is controlled by their companies and can be changed according to their own wishes and needs, The purpose is to make illegal profits. In the market, many investors who don't know the truth are cheated because they lack the knowledge of financial investment. They are in the spirit of speculation to earn profit. Once they are put in, these so-called virtual currencies will be manipulated by the company in the background, resulting in the loss of money. When investors enter into such a game, they often change from the original intention of speculation to gambling. When they buy at a high price and see that the price continues to fall, they will naturally make up their positions and make additional investment when there is a rebound. In this way, they are repeatedly cleaned up and cut leeks. Finally, they sink deeper and deeper and lose their property. It is precisely because the price is controlled by the company, Therefore, these companies make huge profits, even beyond the imagination of ordinary people. What we want to say about this market phenomenon is that it is not the fault of blockchain technology itself, but that it is caused by some illegal people in the market who stealthily changed the concept, took advantage of people's lack of professional knowledge of blockchain technology and financial investment, and grasped the psychology of greed for wealth< br />
​

the existence of these black sheep in the market confuses the public and disturbs the market. As a result, the innovative application of business scenarios based on blockchain technology has brought serious practical obstacles to the healthy development of social economy and value creation of entrepreneurial and innovative projects, such as the "structural hole investment and Financing Ecological Chain Intelligent System" project, In fact, it is based on the innovative application of blockchain + AI + OKR and other technologies in the investment and financing ecological business scenario, and redefines the investment and financing business model. The purpose is to provide enabling services for the three groups of project parties, resource providers and investors in the ecological chain to create value and fulfill value transactions, so as to significantly improve the success rate of investment and financing for the three groups of customers, without issuing virtual currency, Without manipulating the price of the virtual money market, it is a good project for the healthy development of the social economy, which is also affected. It is really painful and difficult, but it has nothing to do, and it can only bear the hardships silently. Today's view is: blockchain fraud is guilty, and blockchain technology cannot be innocent.

5. Blockchain technology is of great significance in the fight against luxury goods counterfeiting. As a solution cloud service for multi instry landing applications, Zhongan chain cloud has successful cases such as bubuji and diamond anti-counterfeiting, and it is slowly showing its talents in luxury goods.

6. There is no clear content for proposing blockchain technology. Blockchain technology is a key to proction and marketing with instrial park as the leading role. There are planting instry and breeding instry in rural areas. This is a very complex problem, and it is difficult to make it clear in one or two sentences.

blockchain can solve the problem of mutual trust in transactions

< H2 > smart contract solves the problem of mutual trust in transactions

since the beginning of bitcoin, blockchain technology has been developing continuously. In 2014, Ethereum further developed a variety of new functions of smart contract technology. Smart contract is linked in the form of digital, & quot; Once generated, the information recorded in the blockchain will be permanently recorded and cannot be tampered with; It can solve the trust problem of "strange trust"

ulord has the property of smart contract, which introces the design concept of gas, but different from Ethernet gas, every operation consumes gas. Compared with the gas concept of ether, ulord adopts a more simplified and abstract method. The resources and sites that users publish on the ulord consume the resources on the ulord network. Therefore, when users publish resources or sites, they need to bind a certain amount of ulordtoken. With the growth of block height, the ulordtoken will be consumed graally. Users need to fill in a new ulordtoken at the address corresponding to the consumed site to ensure the ownership of the domain name. At the same time, through the side chain technology, it can be compatible with the Ethernet virtual machine, publish smart contracts, and allow users to publish their own tokens. There is a certain proportion of exchange relationship between tokens and ulordtoken. Ulord allows users to customize the release of their own site services, and by issuing their own tokens, they can operate their own site

< H2 > ZK snark technology to protect transaction privacy

ulord will adopt the most mainstream privacy protection ZK snark technology to protect transaction privacy. In the ulord blockchain, creating an effective transaction includes the following three things:

1

2. The sender proves that he is the "holder" of the currency by means of authorized signature

The input of transaction is equal to its output

the work of proving that money has not been spent before is done by the ledger itself, which does not require the sender to do any work. The sender only needs to prove that he is the holder of these currencies, and he wants to send these currencies by means of electronic signature through the private key corresponding to the address. In order for the signature to be verified, the sender's address must be public. Correspondingly, the receiver must disclose the receiving address to complete the transaction process. In the use of ulord, it is simple to verify that the input and output of the transaction are equal, because the number of transmissions is fully revealed

8. The procts of block chain Baijiu have already been sold in the market, such as millet wine with grain, the Yanghe River Dream Blue high-end Baijiu, all support the technology of block chain. In this process, as long as we ensure the effectiveness of the tracking method and get through the relevant supply chain, we can achieve anti-counterfeiting traceability. Zhongan technology, an independent research and development company of blockchain in China, already has relevant solutions.

9. It is actually a little complicated, but the official account of Zhang Ji's block chain has already made this content very clear. It is said that these steps are: first, all raw data of the drug will be registered on the block chain, once the upper chain can not be modified. Secondly, all the data on the blockchain are completely protected, and no organization can tamper with and damage it at will. Most importantly, as a complete ecological existence, any participant can supervise the operation of the whole ecosystem. For example, anyone has the right to consult the drug proction approval issued by the supervision and administration department. If the drug information proced by an enterprise is inconsistent with the approval document, the system can automatically retrieve it. All the raw materials used by the manufacturer will also be registered on the blockchain, and the raw material suppliers can see the information. If the raw material information is inconsistent with the actual situation, the raw material suppliers can report the situation to the supervision and management department. Each proct, which proction batch, which proction line, what links it has gone through, and its responsible person are recorded one by one. In this way, whether it is internal audit self-examination, or external social supervision, it is possible to find false files for the first time. Combined with the Internet of things sensor technology, the system can automatically find the fake proction files. In this way, fake and shoddy drugs will not appear on the market, and will be found and intercepted halfway.
