IPFS
IPFS (InterPlanetary File System) is a peer-to-peer distributed file system protocol designed to create a permanent and decentralized method of storing and sharing hypermedia in a distributed file system. It uses content-addressing to uniquely identify each file in a global namespace, connecting all computing devices with the same system of files. This enables resilient, censorship-resistant web applications and data storage without reliance on centralized servers.
Developers should learn IPFS when building decentralized applications (dApps), content distribution networks, or systems requiring immutable, permanent data storage, as it provides a robust alternative to HTTP for hosting and accessing files. It is particularly useful in blockchain projects, peer-to-peer sharing, and scenarios where data availability and censorship resistance are critical, such as in Web3 ecosystems or archival systems.
