1. The domestic blockchain technology has put forward the concept from the beginning, and now it has been applied to the actual business scenarios, such as the vonetracer traceability system of wanglian technology, and their blockchain Traceability Technology has been applied to the actual agricultural procts.
2. The following points are the characteristics of the blockchain summarized by jinwowo group:
1 - Decentralization: because the blockchain relies on each node to achieve system maintenance and ensure the authenticity of information transmission, it is based on distributed data storage without centralized management by a certain center, Therefore, the attack and tampering of a node will not affect the healthy operation of the whole network
2-DE Trust: the establishment of a connection between any two nodes does not need to trust each other's identity, and the data exchange between the two sides does not need the basis of mutual trust. Since all nodes in the network can act as "supervisors", there is no need to worry about fraud
3 - extensible: blockchain is an underlying open source technology, on which various kinds of extension, decentralized and distrusted applications can be realized<
4 - anonymization: the two sides of data exchange can be anonymous, and the nodes in the network can exchange data without knowing each other's identity and personal information
5 - Security and reliability: because the activities between any nodes are supervised by the whole network, and the database adopts distributed storage, for hackers, first, they can't disguise and cheat, Second, we can't control the network only by conquering a node.

3. 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.

In the bear market of blockchain, how to find the real valuable blockchain projects? Xiaobian explains from the following aspects:
1. Use the blockchain security technology testing center to see if it is MLM coin or air coin
no matter how advanced the concept is and how exaggerated the slogan is, the essence of any project still depends on technology. Blockchain projects without technology are just like the emperor's new clothes, We need a mirror that reflects the emperor's new clothes - blockchain security technology testing center
As one of the important initiators of blockchain security technology testing center, Tianhe Guoyun, the provider of ulord public chain technology, provides code audit function, which is a sharp tool for blockchain security technology testing center to identify blockchain projects. Code audit is to build a knowledge base of block chain code automatic audit with the help of machine learning and artificial intelligence. It can improve the efficiency of code audit and solve the security problem of intelligent contract. Through the quality evaluation of blockchain projects, exchanges, wallets and smart contract codes, blockchain code audit can prevent digital asset security accidents, provide code revision measures, security protection deployment and other services. It is reported that in addition to automatic audit, Tianhe cloud blockchain code audit can also customize expert team projects for all-round audit to help investors identify "fake projects" to a greater extent2. Look at the team of blockchain project
the blockchain field can be regarded as a comprehensive field, involving cryptography, mathematics, economics, even social management and other disciplines. We have a reliable team. As I mentioned above, the ulord project brings together a large number of high-level R & D and operation personnel
3. It is not only the concept of stir frying, but also the application of it
there are many startups in the field of blockchain. If you want to become a few widely recognized high-quality projects, it is not feasible to just speculate on a set of concepts or theories. Only the projects with the ability of making blood and doing things on the ground are good projects
at present, DAPP ushare, an application based on ulord public chain, has been officially tested on October 15. Ushare Youxiang is the first decentralized experience value sharing platform in the world, and the first DAPP based on ulord public chain. Through the decentralized consensus mechanism, we can build an open, fair and just content evaluation system, encourage high-quality experience procers and experience sharing disseminators, and let the value of high-quality experience flow
there are nearly 100 teams and projects carrying out negotiation and cooperation with ulord public chain
4. Communities have autonomy attributes
whether communities have Dao (distributed autonomous organization) attributes, which is naturally suitable for blockchain,
about community governance. Whether it's the operation mode of the community or the organizational form of the developer community, it's actually a process from quantitative change to qualitative change. We have realized the importance of community
ulord adopts the community autonomy mode of "everyone can participate and contribute to the ecology"
we will have some new community governance modes, including the cooperation of some developers and the cooperation mode of large-scale open source community, which will be born and flourish
The incentive system mainly includes three aspects: first, participation in bookkeeping; Second, the contribution of network resources; Third, participate in community construction. As mentioned above, in the accounting part of our whole budget system, the pow + POS part accounts for 60%, the contribution level of participating in open source community code accounts for 10%, and the remaining 10% is used as an incentive for community operation. Therefore, we hope that more people can participate in the construction and promotion of ulord. We hope to build a platform, but the dividends obtained by this platform should be shared with everyone in the largest range, which is essentially different from Internet procts5. Recently, the hottest investment is bitcoin. From financial tycoons to ordinary people, they are talking about the surge of bitcoin. Bitcoin is a kind of blockchain. I believe there are still many people who don't know much about blockchain, so today we will explain in detail what blockchain is? How to search blockchain technology patents? What is blockchain? More than 10000 years ago, human beings began to learn to use shells as an intermediary for exchanging materials, and later developed into currency. With the development of network, the circulation of digital currency has graally replaced the traditional currency, and now people's payment methods have undergone unprecedented changes. The emergence of encrypted electronic currencies such as bitcoin, Ethereum and litecoin has further prompted the whole financial system to face up to and start thinking about transformation. However, there is an important technical support behind the development of encrypted e-money which is not affected by the traditional financial system;; Block chain. 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. How to search blockchain technology patents Blockchain Revolution & sup1; A book has mentioned that blockchain is a public database, which records all transaction information and can effectively prevent tampering; It is a distributed system, which does not store on a specific server or node, but scattered in countless nodes on the network, each node only retains part of the information; It is a kind of consensus agreement, which follows a mechanism together. As the underlying technology behind cryptocurrency, including identity authentication, medical record preservation, market forecasting, asset trading, etc., blockchain is graally applied. To observe the patent applications related to global blockchain technology, the author suggests that you should refer to the definitions of block chain, distributed ledger and smart contract to expand your search conditions, rather than only limited to the patents using the word block chain. What is blockchain? How to search blockchain technology patents? If you have more questions about patent inquiry, you can continue to pay attention to Bajie intellectual property or contact us by telephone.
6. 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.
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.

7. There is a misunderstanding here. We all think that the technology is advanced and difficult to understand. It is difficult for us to understand the technology of non professional technicians, let alone use it to judge whether a project is worth investing or not. In fact, the technology is not so difficult to understand. The underlying technology of the blockchain is more of a kind of mathematical logic, which takes time to understand. However, it does not need the programming foundation, and ordinary investors can understand it. We can all make value investment by looking at technology.
