+// but uses typical multihash semantics used when reading/writing cidlinks.

+// Using multihash as the storage key rather than the whole CID will remove the
+// distinction between CIDv0 and their CIDv1 counterpart. It also removes the
+// distinction between CIDs where the multihash is the same but the codec is
+// different, e.g. `dag-cbor` and a `raw` version of the same data.
