Why is distributed storage IPFs popular? Ouke cloud chain five minutes to teach Xiaobai to understand

        Recently, as the blockchain has been included in the "14th five year plan", it has attracted wide attention again, and various new technologies and applications in this field have also been surging. Recently, filecoin (FIL) has attracted many people's attention due to its explosion. Fil was included in the five trust products launched by the international capital giant gray fund two days ago. The favor of the capital market reflects, to a certain extent, that the market is optimistic about the prospect of the new technology IPFs behind it. In fact, as early as November 6 last year, the general office of the State Administration of radio and television issued the notice on printing and distributing a series of white papers on the application of blockchain technology, which repeatedly mentioned IPFs and blockchain distributed storage, affirming the application value and technical advantages of IPFs.
        At the same time, distributed storage has also been a focus of Amazon, Alibaba cloud and Tencent cloud. IPFs protocol can be simply understood as a representative of distributed storage. It is essentially a kind of internet protocol like http. According to the definition of IPFs, "interstellar file system (IPFs) is a network transmission protocol designed to create persistent and distributed storage and shared files. It is a content addressable peer-to-peer hypermedia distribution protocol. Nodes in the IPFs network will constitute a distributed file system." As for the relationship with HTTP protocol, some people say that IPFs replaces HTTP, while others think that it is an important supplement to http.
        If we summarize the advantages and characteristics of IPFs, "distributed", "point-to-point" and "content addressing" are its long recognized potential. How to understand these three advantages?. First, let's talk about the "distributed" storage mode. It is simply understood that huge data no longer need to be stored in the same database, but are stored in all nodes within the network. According to the fault-tolerant mechanism of IPFs, the data will be copied in a sufficient amount and stored separately in databases in different regions. Even if a certain data is completely destroyed, it can be completely restored through the backup of other nodes, ensuring the security of data on IPFs.
        Secondly, how to understand the "point-to-point" characteristics of IPFs? That is, data transmission is no longer centralized through the same database, which is equivalent to private customization of data storage and retrieval. For example, I want to download an MP3 file. In the traditional way, this MP3 file may be stored in the database of kugou. However, the database of kugou is obviously not only this MP3 file. Therefore, when all people download the files they need at the same time, there will be downtime. The file access of IPFs is that the node (you) directly accesses the node (storage node) that stores the data, and no intermediate unified processing is required. For example, some relatively large files are usually not stored in the same node, but are cut into several copies by encryption algorithm, and then distributed and stored on nodes around the world.
        When the download is initiated, IPFs captures and assembles all these node lists into a complete file in parallel, and the parallel speed is much faster than that of downloading the complete file directly. For the non-public data of some users, effective privacy protection can also be achieved through encryption technology, and their access and download can only be authorized. Finally, let's talk about the "content addressing" retrieval method of IPFs core. In the HTTP protocol, it is addressed according to the address, that is, when you download a movie, you need to tell the computer the corresponding IP address or domain name of the movie. Content addressing is to hash map the movie to obtain a unique "hash value". When searching for the sum, it is directly retrieved through the hash value. When downloading, it is directly downloaded point-to-point.
        Moreover, IPFs will check whether the "hash" has been stored in advance. If it has been stored, it will be directly read from other nodes without repeated storage. In general, no matter whether it can really replace HTTP in the future, it does bring us a new breakthrough in data processing speed, security, low cost and security.
