Distributed and decentralized

1. Sharing from regional TV network: in a system with many nodes, each node has a high degree of autonomy. Nodes can connect freely to each other to form a new connection unit. Any node may become the stage center, but it does not have the mandatory central control function. The influence between nodes will form nonlinear causality through the network. This open, flat and equal system phenomenon or structure is called & quot; Decentralization & quot;.

2. Decentralization is a phenomenon or structure, which can only appear in a system with many users or nodes, and each user can connect and influence other nodes. Generally speaking, everyone is the center, and everyone can connect and influence other nodes. This flat, open-source and equal phenomenon or structure is called "decentralization"< Br > at the same time, "decentralization" is one of the typical features of blockchain, which uses distributed storage and computing power. The rights and obligations of the whole network nodes are the same, and the data in the system is jointly maintained by the whole network nodes, so that the blockchain no longer relies on the central processing node to realize the distributed storage, recording and updating of data. Each blockchain follows a unified rule, which is based on a cryptographic algorithm rather than a credit certificate, and the data update process needs to be approved by the user, so that the blockchain does not need the endorsement of intermediaries and trust institutions< The characteristics of br> de centralization:
centralization is first reflected in diversification. In the Internet world, there are no more than several portals has the final say. Various websites have begun to voice their own voice, express different choices and different hobbies, and these websites are distributed in every corner of the Internet world. Br > decentralisation is followed by the centralization of people, and decentralisation of content has become a trend, and people have become the key force to determine the survival of websites. It's a great change to build a website with indivials who lack interaction to gather talents and contribute their wisdom in the form of a circle. That is user-oriented, humanized< < br > decentralized content: < br > decentralization is the form of social relationship and content generation formed in the development of the Internet, which is a new network content proction process relative to "centralization"< Br > compared with the early Internet (Web1.0) era, today's Web (Web2.0) content is no longer proced by professional websites or specific groups of people, but is created by all Internet users with equal rights. Anyone can express their views or create original content on the Internet to proce information together< Br > with the diversification of network service forms, the decentralized network model is becoming clearer and more possible. After the rise of Web2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can create or contribute content together< After that, with the emergence of more simple and easy-to-use decentralized network services, the characteristics of Web2.0 became more and more obvious. For example, the birth of services more suitable for ordinary Internet users, such as twitter and Facebook, made it easier and more diversified to proce or contribute content to the Internet, thus enhancing the enthusiasm of Internet users to participate in the contribution and recing the threshold of procing content. Eventually, every netizen becomes a tiny and independent information provider, making the Internet more flat and content proction more diversified.

3. Compared with the traditional centralized storage and centralized cloud services, the two complement each other and expand the market of data storage and computing, which will constitute the two cornerstones of the future digital economy. China has efficient, stable and cheap power and network infrastructure, which provides sufficient soil for the development of decentralized cloud computing. Taking IPFs as an example, 90% of the total network computing power of IPFs is located in China. In the future, China will become the leader of IPFs. Taking xnmatrix as an example, it has become a global computing power leading decentralized cloud computing platform.

4. Due to the use of Distributed Accounting and storage, there is no centralized hardware or management organization, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system
in the future, jinwowo will continue to tap the value of blockchain technology in the commercial field, give full play to the advantages of big data services, add value to user behavior, break the ice for the development of small and medium-sized enterprises, and build a real, efficient, safe and honest Internet community of destiny.

5. Massive data has brought three problems: higher cost of data storage, privacy and data security; The liquidity of data assets. The traditional centralized storage and computing does not solve these three problems well. Since there is the advantage of centralization, there will be the logic of decentralization. Based on decentralization, the world will proce new proction factors and new application ecology. At present, IPFs storage and distributed storage is the representative of decentralized storage, corresponding to the decentralized cloud computing platform represented by xnmatrix and Berkeley.

1、 What is a distributed system

A: distributed system is more accurately a system architecture concept, not a technology. In short, it is to distribute the operating system in different computers, which are managed together

Second, what is the function? What are the benefits

A: improve safety and efficiency

When it comes to blockchain, we often encounter the concept of "decentralization". So what is decentralization? Nakamoto has solved the difficult problem of "point-to-point e-cash" defined by himself. In this process, he "invented" the blockchain technology. Bitcoin system integrates technology and theory of cryptography, game theory and software engineering. Blockchain technology is an innovation formed by ingenious combination of existing technologies. Nakamoto didn't solve the problem of "peer-to-peer e-cash" out of thin air. He followed the footsteps of his predecessors, but he completed the last leap

"decentralization" is the competitive advantage of removing the centralized central node. It does not mean that there is no center, but the center node is a relatively neutral existence. These central nodes will not be mandatory. For a fully decentralized system, the connection between nodes is not completed by specific nodes, and all nodes can store and update data on the system, so as to achieve openness

decentralized blockchain is essentially a decentralized distributed ledger database. The simple understanding is that the data of blockchain is stored in many nodes of the network. The traditional way of data storage exists in one or several large nodes in the network. From this point of view, the so-called centralization and decentralization is the difference in the number of nodes storing data. Therefore, the decentralization of blockchain is relative. Data only exists on one node, which must be centralized. But if there are 100 nodes, they can be said to be decentralized relative to one node, but the degree of decentralization is not the same. At the same time, centralization and decentralization are not contradictory, and they are not completely opposite, because the word "de" in decentralization means the process of weakening and eliminating the center, rather than the concept that there is absolutely no center, which is completely opposite to non centralization
