IPFS

The InterPlanetary File System (IPFS) is a decentralized, peer-to-peer protocol for storing and accessing files across a distributed network of computers rather than relying on centralized servers. IPFS uses content-addressable hashing to identify files by their cryptographic fingerprint, enabling resilient, censorship-resistant file distribution. When integrated with blockchain, IPFS solves critical problems around data permanence and decentralization, allowing NFT metadata and smart contract artifacts to exist independently of any single entity. The protocol creates a redundant network where files remain accessible even if individual nodes go offline. Example: NFT creators use IPFS to store artwork and metadata, linking their blockchain tokens to files accessed through IPFS gateways, ensuring the media persists even if the original hosting service disappears. Why it matters for blockchain infrastructure: IPFS is foundational to blockchain's decentralization promise, enabling true data ownership and censorship resistance. Without IPFS-like solutions, blockchain applications depend on centralized servers, undermining the core benefit of distributed ledger technology.
