The legality of IPFs / filecoin: protecting personal privacy from disclosure

5 Line code , Can let wechat small program on the shelf to their own APP in | Register and send it to Dajiang 、 Huawei 、 Cherry keyboard ！>>>

A lot of people find out , You can click on a piece of clothing or other goods on the web , Later, we will receive a series of related advertisements , It makes people wonder ： Whether they're being tracked , Whether your data is leaked ？

　　 The present , We go online 、 Use APP The data generated is stored on the centralized server . These centralized servers have a say in our data , It may lead to the disclosure of our data without consent or authorization 、 The abuse of .

　　 If one day , There is an error or problem with this centralized server , Then the data could be lost , It can never be restored . It's just like the one I used before APP, Later this one APP We need to reform our company , This project has no staff to maintain and upgrade regularly , Addressing error occurs directly , Before Xiaobian, the words and photos on it can't be displayed , Only dumb people can eat Coptis ...

　　 and IPFS（ Interstellar file system ） Unlike a centralized server , It's a point-to-point agreement . The difference is the way it handles files ： Don't use location based addressing （ For example, domain name 、IP Address 、 File path, etc ）, Instead, use content-based addressing . Will file （ Or directory ） Add to IPFS After the repository , It can be referenced by its encrypted hash .

　　 that IPFS How is the data stored ？

　　 When we upload a video to IPFS On the Internet , First copy the file , After that, a complete copy is stored in a server . If it is greater than 256KB, It will be fragmented asymmetric encryption , And then it's distributed to the memory of storage providers around the world .

　　 Some of this may be in your friend's memory , It may also be stored in the United States by a blonde . This is it. IPFS One of the characteristics of ： De centralization .

IPFS Let's replicate our data N+1 And keep them in different areas , If the data of an area is destroyed by human activities or natural disasters , Through data backup in other regions, all data can be recovered completely .

　　 meanwhile , And don't worry about our data being stolen or tampered with , The encrypted data is part of the data , Can't be viewed , The person who provides storage doesn't know what's inside , This is it. IPFS Another ： tamper-proof , It protects privacy better than centralized storage , Guaranteed storage in IPFS Data security on .

IPFS Compared with the current storage hard disk , It will cost less , When we need this video , We just need to ask IPFS System “ Who has this document ”, here , The searcher will find that there are several storage providers who own this file , But each provider, due to the distance of transmission or other reasons , The set transmission costs vary , thus , According to their own needs, searchers can choose the relatively convenient and less expensive one .

　　 In terms of data transmission speed ,IPFS There are different ,IPFS It's point-to-point protocol transmission , Different from the one to many mode of centralized transmission , This avoids the cluster pressure and overload caused by centralized transmission , Reduce the chance of mistakes and crashes , More convenient , quick , guaranteed , Access loading is definitely faster than centralized http Faster in mode .

　　 therefore IPFS It can provide space for people with storage needs , At the same time, it can also make people who have extra storage space use their own resources effectively , The heart has a direction 、 Work and gain , In order to make more people willing to contribute their own hard disk to save other people's data , There's a reward mechanism for storing data ——Filecion, It all becomes more interesting .

　　 at present ,IPFS Still on the way to decentralized storage , Now , Its motivating layer Filecoin After the launch , Expect it to perform better .
