IPFs is a content addressable peer-to-peer hypermedia distribution protocol. IPFs combines the existing successful systems, such as distributed hash table, BitTorrent, version control system git, self certified file system and blockchain, to form a file storage and content distribution network protocol. IPFs is also an open source project
IPFs attributes:
1, permanent, decentralized save and share files
Peer to peer hypermedia: P2P stores all kinds of data3. Versioning: it can trace the modification history of documents
extended data
advantages of IPFs:
1. Content addressing: all content (including links) is uniquely identified by its multi hash check sum
2. Tamper proof: all contents are verified by their checksums. If the data is tampered with or damaged, IPFs will detect the data
3. De rendancy: all objects with identical contents are stored only once
PFS does not require every node to store all the content. The owner of the node can choose the data he wants to maintain freely. Besides backing up his own data, he voluntarily provides services for other concerned content source: network interstellar file system
