content-addressed storage
Storage where an object's identifier is derived from a hash of its bytes, as in an IPFS CID, so the address itself proves what it delivers: change one byte and the identifier changes. It is a stronger immutability claim than a change receipt, which proves a difference between two dated observations.
What content-addressed storage does not show
It says nothing about authorship or time: anyone can store any bytes, and the identifier does not say when. Paired with a timestamp proof it becomes a dated, verifiable copy; alone it is only a verifiable copy.
