IPFS (InterPlanetary File System) is a decentralized protocol for storing and sharing files using a peer-to-peer network. It allows content to be identified by its hash rather than its location, ensuring permanence and resilience against censorship.
To use IPFS, one can install a local node or use a hosted gateway. Providers like Pinata, Infura, and Web3.Storage offer pinning services to keep files available on the network. Costs vary: some offer free tiers, while premium plans depend on storage and bandwidth needs.
