Datacoin Core 0.16I thought I should quote some of the PM's between the developers in this forum:
Due to everyone's hard work, ... fwiw, my Linux-hosted datacoin-intermediary is now fully synced from the datacoin node on my remote server via a bootstrap.dat that I made by simply concatenating its blk*.dat files. I'm aware that this approach preserves any orphans present in the original files but I'm using a separate client (on OS X, immaterially) which I've configured to connect only to the datacoin-intermediary client on my local Linux host and is syncing from this restricted local network - which is one recommended way to filter out any orphans and produce a contemporary linearised bootstrap.dat file.
My next step will be to merge the Primecoin and Datacoin 0.16 codebases and see if I can get Datacoin Core to sync from the datacoin-intermediary on the OS X client.
(primecoin-intermediary blockchain is still syncing, despite being started a day and a half earlier than the Datacoin client, loads of orphans being received.
Cheers

Graham does emphasize that
...this is investigative work, the intermediary is merely a necessary precondition for any work on augmenting the Primecoin Core code with the Datacoin data storage mechanism. In an earlier piece of work I seemed to be able to identify the components of the mechanism and cleanly separate them out. However, the implementation of several years ago may need extensive refactoring in order to function in the context of a contemporary Bitcoin clone.
Bottom line is that the Datacoin developers are now hard at work on a Datacoin Core 0.16 client.
