Locating blocks on the time axis

[ey51]

Current state

Two blocks with the same timestamp, but one is the parent of the other are drawn one over the other on the time axis.

Proposed change

Location on the time axis can be deduced from parent relation. If a block A points to block B, it should be drawn at a later "index" on the time axis.

Examples

Example 1, in the screenshot below:

• block 5b with blue score 4601
• block ae with blue score 4602
• 5b and ae have the same timestamp, and are drawn on the same "index" on the time axis, however, ae points to 5b, thus it should be drawn "later"

Example 2, in the screenshot below:

• block 12 with blue score 4607 comes before..
• block 35 with blue score 4608, which also comes before..
• block 2b with blue score 4609.
• however, they are all drawn with the same "index" on the time axis, and thus it is hard to understand the blockDAG.

The way the blocks are layed out on the x-axis using blue score as the x-axis index is good.
