I'd like to understand the steps that lead to an eventual confirmation of a transaction. I understand that there are several child transactions required and that the individual weights of each of these need to add up to a certain threshold.
However, what is that threshold? Is it dynamic? And what happens when that threshold is reached? Is it at that point that the node syncs with all the neighbour nodes? Or when does the syncing happen?
Or is a transaction only confirmed when it's available on a certain minimum number of nodes (similar to BTC)?
