IPFS
infrastructure · protocol
A peer-to-peer file network that retrieves content by cryptographic identifier rather than by a server location.
- Also known as
- InterPlanetary File System, content addressing
IPFS, the InterPlanetary File System, identifies data with content identifiers (CIDs) derived from cryptographic hashes. Any peer with the matching content can serve it, making retrieval location-independent.
Blockchains often store IPFS CIDs on-chain to reference larger off-chain files without putting all data in block space. Gateways provide regular HTTP access for browsers that do not run IPFS natively.
