The size of blockchain distributed storage

1. In short, the data of the blockchain is formally stored in the blockchain through the formula algorithm process of the block. All nodes in the whole network express that they accept the block, and the way to express acceptance is to make the random hash value of the block the latest block hash value. Xingqun manufacturing will be extended based on the blockchain.
2. Blockchain distributed storage is a kind of decentralized storage, which does not store data on one or more specific nodes, but scattered storage
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. The central storage technology has developed very mature. But at the same time, new problems also appear, the centralized network is easy to be crowded, data is easy to be abused. The traditional way of data transmission is from the client to the cloud server, and from the server to the client to download. The distributed storage system qkfile is transmitted from the client to N nodes, and then downloaded from these nodes to the client, so the transmission speed is very fast. Compared with the central protocol, it has fast upload and download speed, can effectively gather idle storage resources, and can greatly rece the storage cost
with the increasing number of nodes, the trend of qkfile market is becoming prominent, and the number of users will increase exponentially in the future. Distributed storage will have many applications in the future, such as data storage, file transfer, network video, social media and decentralized transaction. The control of the Internet is more and more concentrated in the hands of a few large technology companies. Its network is decentralized. Just like distributed storage, it is always community-centered and user-oriented. Distributed storage is the future of information technology and Internet functions. With distributed storage, we can create a more free, innovative and democratic online experience. It's time to take the Internet to a new stage
as a very popular star project this year, the future development of qkfile will promote the progress of the Internet and bring great benefits to the whole market. Distributed storage is based on the infrastructure of the Internet, and blockchain distributed storage is superimposed with artificial intelligence and big data. Today's central storage is a huge supplement. The arrival of the distributed era is not to replace the current central Internet, but to make the future data storage develop better and bring unimaginable vitality to the whole market ecology. First look at the consensus, then look at the application. Qkfile creates an infrastructure platform, just like Alibaba cloud, which is a video website for game makers and e-commerce. This is called the application layer. At this stage, in terms of performance, frankly speaking, compared with traditional cloud storage, it has little competitiveness. However, on the other hand, a new trust environment of decentralized storage is very important. In this environment, many related applications can naturally be derived, and the market potential is very large
although qkfile is still far away from real business, first of all, the economic model of qkfile has not been finalized. Secondly, qkfile needs to focus on the development of distributed storage, business logic and Web3.0. Only by opening up the track of distributed storage can it have the strength to lead the development of the whole instry. People realize the disadvantages of centralized storage, Many enterprises have begun to accept the distributed storage mode, that is, distributed storage DAPP applications touch users. So qkfile will definitely have more commercial applications in the future. The ability to create super local and efficient storage mode. When users want to store data on the qkfile network, they can get rid of the huge limitations of centralized storage and geographical location. Users can see the miners and their market prices of online storage, and miners compete with each other to win the storage contract. The user selects the competitive miner, the transaction is completed, the user sends the data, and then the miner stores the data. The miner must prove the correct storage of the data in order to get the qkfile reward. In the network, the storage security of data is verified by password proof. Miners submit their storage certificates to the network through the new block chain. Through the verification of the new blockchain released on the Internet, only the correct blockchain can be accepted. After a period of time, miners can get transaction storage fees and get blockchain rewards. Data will be spread where it is more needed. Rotating data will flow within the scope of the earth, and data acquisition will be continuously optimized. From small mining machine to large data center, all people can lay a new foundation for the construction of human information society and benefit from it through joint efforts.

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.
the margin ratio and handling charge are stipulated by the exchange, but different companies add different amount on the exchange
our company adds the least amount: if the margin is not added, the handling charge is only 0.01 0.01
