Xianyun blockchain distributed private cloud storage network

1. blockchain distributed storage is a kind of decentralized storage, which does not store data on one or more specific nodes, but scattered storage

2. Cloud computing is usually defined as providing dynamic, scalable and often virtualized resources through the Internet, but it is often a centralized organization that provides cloud computing platform. The network composed of blockchain generally has no specific organization, so blockchain is closer to the definition of distributed computing system and belongs to a kind of distributed computing. However, blockchain is able to realize cloud storage. Unlike the centralized cloud storage, blockchain has some cloud storage solutions that are decentralized.

3. One is that each node of the blockchain stores complete data according to the block chain structure. Traditional distributed storage generally divides the data into multiple copies according to certain rules
Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes
data nodes can be different physical machines or different instances in the cloud
the above is the difference between the blockchain technology of jinwowo network analysis and the traditional distributed storage, for reference.

4. Centralized storage and distributed storage
most of the current storage is centralized storage, which is stored in the traditional centralized server. If the server goes down or fails, or the server stops operating, a lot of data will be lost
blockchain, as a distributed database, can solve this problem well. This is determined by the technical characteristics of blockchain. The digital records on the blockchain can not be tampered with or forged. The smart contract enables us to work together more efficiently, so as to establish a credible digital economic order, improve the efficiency of data flow, break the isolated island of data, and create a new storage mode.

5. IPFs is a permanent, decentralized method of saving and sharing files based on blockchain. It is a point-to-point distributed protocol. Focus on Shanyan data, mainly do data storage in finance, new energy, medical, big data and other instries, and provide overall solutions!

6. IBM, Microsoft, Oracle, Accenture, Tencent, Alibaba, Jingdong, network, etc. have all done it. Many large banks, including Ping An Bank, have also launched their own blockchain solution platforms or solutions. However, it should be added that large companies do not mean strong technical strength, because blockchain is still in the hot stage of concept in the world. Unicorn blockchain companies are likely to emerge in the future, such as EOS abroad and Binhe Yun patent technology and application landing in China are much higher than those of large companies.

7. What is risk? Futures contracts provide leverage (inversely proportional to the guarantee rate). The volatility of underlying assets determines the volatility of futures
it's normal for the stock market to fluctuate by 30-40% a year, and the fluctuation of exchange rate by more than 20% is very large. However, if the leverage ratio is included, the profit and loss fluctuation of foreign exchange futures may be much higher than that of stock market futures, but these are just numbers games< In the end, derivatives only provide a mathematical calculation.

8. It can be
e-dinar internal market allows P2P transactions without commission and foreign exchange restrictions, and digital gold currency e-dinar supports any means of payment in the market< br /> http://pinpai.szonline.net/pp0615/20160615/567354.html?__ r=138

9. Filecoin is a token on IPFs, and filecoin is a way to reward miners by contributing idle hard disks. Filecoin adopts a new algorithm (proof of workload). In short, if you have enough hard disk capacity, you will get more rewards for filecoin
filecoin is a decentralized distributed storage network and the only incentive layer of IPFs. Filecoin uses the blockchain token system to issue the token, which is referred to as fil. Based on IPFs protocol, filecoin constructs a decentralized storage trading market for cloud storage, including "storage" and "retrieval". This market runs in a blockchain with local protocol token (FIL), and miners can obtain fil by providing storage for customers; Similarly, customers can use fil to hire miners to store or distribute data<

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.
