Video: Lecture on OK Blockchain 60-Features of Blockchain: Decentralization

From PC Internet to mobile Internet, from e-commerce to cloud computing, 20-year-old Ali can be said to have a very sensitive technical sense of smell, did not miss any trend of the times, and this time, Ali is staring at the blockchain. Ma Yun once said that for Alibaba, blockchain is not a gold mine, but a solution. Alibaba must have a blockchain, and no blockchain is dead .

Of course, this sentence may be a bit exaggerated, but it is by no means an empty talk. After all, taking history as a mirror, Nokia did nothing wrong, but just lost. At present, it is not only the Ali family that is optimistic about the blockchain. Tencent ’s blockchain invoice has been piloted in Shenzhen, and blockchain games have been launched. ’s blockchain logistics, Baidu ’s public chain, and Huawei ’s blockchain + Cloud computing has been pushed into the process one by one, and it is intriguing to think about it. Why do the giants optimistic about the blockchain?

Therefore, today, Xiao Kjun will talk about its characteristics, what advantages does the blockchain have, and why should it be favored by giants.

We all know that big data is a trend. For the giants, whoever can manage the data better in the future will have the advantage. The blockchain is equivalent to a database, which can help giants solve this problem. Compared with the database of the Internet, the unique feature of the blockchain is its decentralized characteristics, which is also the most important feature of the blockchain. So what is centralization?

For example, the software we usually use for shopping is actually a centralized platform. Whether you choose a product or a payment transaction, there is an inescapable role for buyers and sellers, the company that created the software. It can obtain all the data of the user in this process, and can even determine the quality of the seller's store sales (such as search ranking). The power is very large and is the central role in the entire process. This is centralized.

The so-called decentralization is to remove this center to decentralize the power that originally belonged to the centralized role, and users can freely conduct point-to-point transactions. For example, the data generated by the original user's shopping is managed by the user. The centralized company can only retrieve it and has no right to view it. For another example, the quality of the merchant will be determined by the user. The centralized company has no way to do it. Search ranking, affecting the sales of businesses, etc., this is decentralized.

The benefits of decentralization are reflected in two aspects. On the one hand, it reduces the network security risk . For example, the original Internet data is stored in a central node, and once the hacker attacks the central node, the entire network can be destroyed. After decentralization, because the network is maintained by multiple nodes, each node has equal rights, even if one node has a problem, it will not cause a large impact. On the other hand, it is to decentralize the power of centralized companies , avoid the emergence of data monopoly, and ensure the privacy of users' information. Therefore, to some extent, decentralization can be described as communism in the Internet world.

The reason why blockchain is favored by giants is also a general trend, because as data becomes more and more important, more and more people realize the importance of data, and ultimately the decentralization of data rights is definitely an inevitable result Of those data monopoly companies, it is impossible to really let this product appear). Therefore, who can balance the relationship between data processing efficiency and user information security, who can better face the future.
