I still don't grasp why you include double-headed arrows?
All the relations between blocks have one direction, being (imo) always the most important relation the "direction" of the hash which points always backwards, from a block to the previous block.
If you want to include an arrow pointing forwards (as I interpret, that the miner which generates the block makes it possible to append the next block, or as I wrote before, as a general timeline starting at the genesis block), it should be of another color or tone.
And the space between the blocks should be empty, I think. You could, in theory, try to include a symbol representing the mempool, but that would be overly complicated imo.
Yes you are right.
Doing differently directed arrow. I want to say that the generation of the next block is based on information from the previous one. Mining.
And this happens simultaneously. And changes in the address in the previous and information for the next. Therefore, there is only one arrow. One color and in different directions.
And the emptiness between the blocks is replaced by a border of a different color.
, but connecting the upper block would just make it a "circle" and that doesn't represent blockchain very well either.
