Tencent applied for blockchain patent

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. 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. 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.

7. All countries are seizing the patent of blockchain. There are still many blockchain applications in China, such as Alibaba, Tencent and Bank of China. Blockchain applications are very popular now. There is a SMIC blockchain service platform project initiated by Changsha high tech Zone, which is blockchain + public service mode, and enterprises are being recruited to join the chain.

According to the information released by the South Korean Intellectual Property Office (KIPO), the number of patent applications for blockchain has increased significantly worldwide

the South Korean Intellectual Property Office released a report on Wednesday (March 21), which showed that the number of patent applications for global blockchain reached 1248 in 2017, and the top five countries and regions were the United States, the European Union, China, Japan and South Korea

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.
