 * One benefit of content-addressable storage is easy deduplication.
 * Many images might depend on a particular [layer](layer.md), but there will only be one blob in the [store](image-layout.md).
 * With a different serialization, that same semantic layer would have a different hash, and if both versions of the layer are referenced there will be two blobs with the same semantic content.
