Not how you ask,
as your first request of putting it "on-chain" becomes the obstacle preventing the following requests
ANNE is a datachain but does things a lot different
the data is not stored on chain
ANNE store data points in the hypergraph
Files that are referenced in the hypergraph are public and are available from original source or can be acquired from other nodes on the network via ANTOR encrypted torrent like file share.
Ghost Files, as mentioned above, are stored by ghost neurons on your local ghost neural network, these are "off-chain" files on your node or a cluster of nodes, and you then can control who gets access to them
you can grant one time access if you wish
but, anyone who does get access essentially has them then, just like a jpeg, someone can right click save, or take a screen shot,
The only way for you to control and own your data
is for it to be 100% under your control
on your own machine.
The ANNE Network is not designed to end up in centralized datacentres, ANNE is designed to keep data distributed in the hands of the people, whilst also allowing users to keep their personal data private
