1, filcoin: The Chinese name of filcoin is Filcoin, which is an open source and public-oriented encrypted currency and digital payment system. The file currency system aims to create a data storage and retrieval method based on the blockchain system, which is created by the "protocol laboratory" based on the interstellar file system. The full name of IPFS is Inter Planetary File System, which is generally translated as "interstellar file system". It is a peer-to-peer (P2P) distributed file system proposed by the protocol lab.
2. Although it is a file system and data storage technology, more accurately, IPFS is a transport protocol. IPFS regards HTTP as an opponent and advertises for it. HTTP (Hypertext Transfer Protocol) is one of the most commonly used transfer protocols at present. If we want to find what we want on the internet, we must enter the website address, which mostly starts with HTTP. HTTP passes through domain name, IP and multiple central servers, and then uploads and downloads files. The advantages of HTTP are irreplaceable. Now we all rely on HTTP for surfing the Internet. However, HTTP also has some problems, such as low execution efficiency, excessive dependence on central servers and backbone networks, and so on.
3. Compared with IPFS, this is a multi-center solution. Content addressing is not through domain name and IP, but through a unique hash key to find data. IPFS is a distributed file storage system. File data is not stored on the central server, but on all eligible computers on the network. Of course, IPFS is not only that, but also has many other functions, and its level and application range are beyond the simple P2P download. In IPFS, there is an incentive mechanism-Filecoin. Participants (miners) can get the cryptocurrency Filecoin reward by contributing storage space and bandwidth.
