The addressing scheme used by the InterPlanetary File System, in which content is identified by a cryptographic hash of its data rather than by location. The resulting content identifier changes if the content changes.

Semantic Classification

Content

  • Content addressing in IPFS derives an identifier from the hash of the content itself, producing a content identifier. Requesting that identifier retrieves the exact data, and any change to the data yields a different identifier.
  • This approach provides integrity verification and deduplication, because identical content always maps to the same identifier, and it enables retrieval from any peer that holds the data rather than from a fixed server.
