.... did a quick audit of the code starting at Mark Pfennig (Nathan Rixham)'s initial "global rename" commit and indeed it seems to be an exact copy of Bitcoin Core v0.9.2.1, other than renaming "Bitcoin" to "Bitmark". I also looked at his other commits before and didn't find anything dishonest. Thus, I am very convinced now that the code is honest and secure (up to the security of Bitcoin Core v0.9.2.1). ...
In your opinion, ¿what are the most important new features in the latest Bitcoin v0.16.3 code that we should adopt ? I can think of the faster blockchain initial downloads for one. Or perhaps we should "simply" transfer our features into the BTC v0.16.3 base (our own genesis block, target block time, DGWv3, CEM, 8mPoW, etc.), and be completely up-to-date.
