IPFs is a point-to-point distributed file system, dedicated to replace http
the difference between IPFs and HTTP
Security: http is centralized, and all traffic is directly carried on the centralized server, which carries great pressure and is easy to cause system crash. HTTP is also vulnerable to DDoS attacks; The storage mode of IPFs is decentralized and partitioned distributed storage, which can not be attacked by hackers, files are not easy to be lost, and security is guaranteed
efficiency: http relies on the centralized service network, so the server is easy to be shut down and the files on the server are easy to be deleted. The server needs to be turned on 24 hours; IPFs adopts P2P network topology, all computers in the whole network can become storage nodes, and the nearby distributed storage greatly improves the network efficiency
cost: http centralized server needs high maintenance cost. Once the centralized database is attacked by DDoS or damaged by force majeure, all data will be lost; IPFs greatly reces the cost of server storage and bandwidth
most of HTTP customers' network access is not localized, and there is network delay. IPFs can greatly accelerate the speed of network access, and the sense of experience will be significantly improved with the localization of network access
usage scenarios of IPFs:
< UL >as a mounted global file system, mounted in IPFs and IPNs
as a mounted personal synchronization folder, version management and publishing are automatically performed, As an encrypted file or data sharing system, as the version package manager of all software, as the root file system of virtual machine, as the boot file system of VM, as a database, applications can write data directly to Merkle da In G data model, obtain all versions, buffers, and IPFs provided allocation
as a linked (and encrypted) communication platform
as a CDN for integrity check of large files (without SSL)
as an encrypted CDN
on Web pages, As a web CDN
as a link, there will always be a new and eternal web
