| 47 ↗ | (On Diff #6201) | It would be preferable to designate this block by something that actually identify it. There is something special about this block, and it is not that it is at height 209. |
| 124 ↗ | (On Diff #6201) | I commented on these tests a million times. They do not check anything very interesting. The node could be on any branch the test would pass, but if we add another test case that shift the hight, then we got to modify everything in the test. Please test what's relevant. |

| 171 ↗ | (On Diff #6232) | It has been removed because it is a duplicate, already tested at line 162 (164 in new version) |
