1. Alibaba
IPR daily, an intellectual property media, recently released a report, which listed the number of
blockchain invention patents published in the world from January 1, 2019 to June 30, 2019, among which China ranked first, accounting for 67% of patent applications. Alibaba ranked first with 322 patents, followed by Ping An of China, with 274 patents, Third, nchain has 241 patents.
2. China has started to establish a national standard for blockchain to promote the construction of blockchain standard system from top-level design, which is expected to be completed by the end of 2019 at the earliest
in this regard, Zhao Wu, founder of Beijing Huashun Xin'an Technology Co., Ltd., also said that although the blockchain has disruptive technology potential, we must realize that the blockchain is still in its infancy, far from reaching the stage of subverting the world
Yu Kequn stressed that the independent and controllable blockchain network is intended not to be controlled by others technically, but also to promote the healthy development of blockchain. Security is the future life of blockchain. Only its own security can make blockchain technology landing. This requires us to pay equal attention to the development of blockchain technology and its security attributes, even ahead of time
in this regard, Li Ming also said that an important part of the standard is the information security standard, which can also see the importance of security to blockchain technology. He also pointed out that the development of blockchain standards does not mean that it will rapidly promote the development of the instry, but give the instry certain guidance. Previously, China has suffered a lot in terms of international intellectual property rights and standards. In terms of blockchain, China has formed more than 200 patents in terms of international blockchain, and even stands in the forefront of world technology. Therefore, we also need to firmly grasp our right to speak

3. Each data block contains time stamp, block number of the previous block, hash value of the previous block, current block data content, etc. In a block, only one person can broadcast first, and the others can make synchronous copies, and can't make changes. Therefore, as long as your chain is complete, and there is no dispute, no modification, you can basically solve the problem of self certification. There are more and more projects of blockchain technology, which can overturn the theory that blockchain is useless.
4. 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.
5. the definition of blockchain
in a narrow sense, blockchain is a kind of chained data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography
broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code
there are many channels to learn blockchain
① you can buy some books related to blockchain, learn some knowledge related to blockchain, take notes in your spare time, and consult relevant information
② watch some videos of blockchain on the Internet, the contents of which are easy to understand, with relevant examples, It's also a very good way to learn
③ you can take part in some offline blockchain learning exchange meetings, or take part in some training courses, and some teachers will answer questions for you
to sum up,
all roads lead to Rome. There are many channels to learn blockchain, and the best one is suitable for you
6. At present, Internet breeding software includes all people raising cattle, Lenong's home, Aishang raising pig, chicken housekeeper, ugly ckling farm, etc. all people raising cattle, falling in love with raising pig and chicken housekeeper are income oriented apps with little user interaction. They are investment income oriented apps. Ugly ckling farm is an app developed by Shenzhen ugly ckling Innovation Technology Co., Ltd., focusing on user breeding experience, Real time online breeding and offline breeding can be synchronized. Those who have children at home and need to raise their own cks to supplement their families can raise their own cks and eat by themselves through this platform, which is visible in real time, green and pollution-free, and recommended by the wall.
7. With more and more blockchain technologies, more and more people apply for blockchain patents. However, in the process of applying for blockchain patent, there are more or less legal and practical obstacles. For example, to determine whether they are qualified for patent, to distinguish which are abstract concepts and can not apply for patent, and so on
however, blockchain technology is still in an open state, just like the Internet in the 1990s, which is open source. Anyone can use it, but they can apply for relevant patents instead of blockchain patents. European crowdfunding has created a new crowdfunding model combining blockchain, digital currency and real assets, which should enable us to apply for a patent.
8. In fact, as of August last year, Bank of America had filed at least 30 patent applications for blockchain technology, while in February last year alone, they filed nine applications with the U.S. patent and Trademark Office
9. Specifically, a large number of distributed points are used to record transactions instead of central records. In this way, the data can not be changed and trust is generated. Further, mediation is used. Logic comes step by step. Now, there are a lot of online blockchain training, which are the most basic contents. No one raised or answered the problems of distributed storage. Through research, I think the most important point for blockchain to be implemented is whether distributed storage can be realized? This problem is actually a problem, at least for now. Is the capacity of the storage point sufficient? Many training institutions often use Taobao to do the case. Buyers and sellers have data on Taobao. Alipay makes intermediary guarantees to ensure that both parties can trade normally. Blockchain technology allows each distribution point to keep accounts, so the storage capacity of each distribution point is estimated to be less than 1 / 100 million of Taobao. How can it be stored? It is impossible to make every point prepare the same storage as Taobao. From the scale, capital are not allowed, even if it can, it can not, because this rendancy is too large, you can imagine, millions of Taobao storage scale, how a waste of resources. The storage space of home computers is not enough for blockchain data storage. So, how to solve this problem? First of all, we should reach a consensus on the scale of bookkeeping. For example, 10000 is the upper limit. In this way, bookkeeping can not be unlimited. Secondly, storage and sharing. Nowadays, computers in many families are hardly used, and the rich space can be shared. Thirdly, the storage technology has made great progress, and the storage capacity is growing exponentially.
