It doesn't 🙂 I'm just testing my patches (which I did on master) and I've noticed that the blocks are not syncing. Now, I know that it's currently expected so it's difficult to asses if all verifications and checkpoints are implemented correctly. I came to the conclusion that I need to test my patches on the
version3 branch. Can you confirm that?
