XT is using the exact same chain/protocol as core aside from the future possibility of block size increase.
XT operates just like CORE as of right now.
You keep repeating that Big Lie, but it's simply not true.
XT is every patch Mike Hearn ever had refused by NACKs in Core.
Conspicuous by its absence from the README is that incoming clearnet connections will kick a Tor peer off.
So don't just trust the description of diffs.
