IPFS stands for InterPlanetary File System, a protocol designed to create a peer-to-peer file-sharing network. An IPFS node is a computer that participates in this network, storing files and helping to distribute them.When a file is added to IPFS, it is broken into smaller pieces, each identified by a unique hash. This allows users to retrieve files by searching for their hashes rather than relying on a single server location. Each node can store a portion of the data, making the network decentralized and reducing the chances of data loss.IPFS nodes communicate with each other to share files efficiently. When a user requests a file, the network finds the nearest node that has it, allowing for quicker retrieval. This method also enhances security and privacy, as files aren’t dependent on one location.Overall, IPFS nodes significantly enhance the way files are shared and accessed across the internet, promoting decentralization and resilience against censorship and downtime.
