I don't see the relevance of these statements to the issue that binary data is impenetrable. All you can do is try one parsing after another until .... oh, a dickpic (or something).
May be I have misunderstood you. For example. File is cut into parts. These parts saved into blockchain one by one. Each part is saved with hash of previous saving transaction. Finally file is addressed by hash of the last part transaction.
Okay, my vagueness at fault: Datacoin (in common with torrenthash) has only
structural metadata, there is no
descriptive metadata and
that's what's blocking the development of a "nice little app" (
