IPFS (InterPlanetary File System) is a distributed peer-to-peer system for storing and accessing files in a decentralised manner. Instead of storing files in one central server, IPFS breaks files down into small pieces and stores them in a network of interconnected computers. This means that files can be downloaded from multiple sources simultaneously, making the data storage process faster and more efficient. IPFS also offers the advantage of greater security and resistance to interruptions than centralised systems.
