View source for Content Addressable Storage

==Full Title or Meme==
A Content Addressable Storage (CAS) allows stored information to be retrieved based on its content, not on its location.

==Context==
* Not to be confused with [[Complexity#Complex_Adaptive_Systems|Complex Adaptive System]] (CAS).

==Problems==
* Fixed content files or documents need to be accessed by the content that they hold, even when the searcher cannot be expected to know exactly where the content is stored.
* While this could be solved by modern search engines, the location of the content may move or be utterly irrelevant.
* As a general rule the content is not expect to change often, or perhaps never change at all, so that the content is a good basis for finding it.


==Solutions==
* A large number of solutions are found on the wiki page [https://en.wikipedia.org/wiki/Content-addressable_storage#Typical_implementation Content-addressable storage].
* The [[InterPlanetary File System]] (IPFS), is a content-addressable, peer-to-peer hypermedia distribution protocol that is often used in [[Identity Management]].
