Inter Planetary File System, or IPFS, is a way to store and share digital information in a decentralized manner. Instead of relying on a single server or computer to hold all the data, IPFS uses a network of computers, called nodes, to store and share the data across the network. This means that the data is not located in just one place, but is distributed across the network.

One of the main benefits of IPFS is that it is decentralized, meaning that it is not controlled by any one company or organization. This makes it resistant to censorship and interference, as there is no central point of control that can be targeted.

IPFS also uses a special system for storing and retrieving data called a content-addressable system. This means that each piece of data is given a unique identifier, called a "hash," based on the content of the data itself. The hash serves as a permanent, immutable identifier for the data and can be used to retrieve the data from any node in the network that has a copy.

To help nodes find the data they need, IPFS uses a distributed hash table (DHT). This is a decentralized data structure that allows nodes to locate other nodes with the data they are searching for.

IPFS can be used to store and share a wide range of digital information, including documents, images, videos, and more. It has the potential to revolutionize the way we store and share data online and is already being used in a variety of industries.
