Thanks for the answer, I think I've understood it, but Could have any problems when a Lite node updates the blocks to the Nodes?

The only reason nodes normally keep blocks around is to give them to other nodes that haven't seen them (i.e. new nodes being setup for the first time). In the case of lite nodes, they won't have the older blocks, so nodes will need to get them from non-lite nodes.

Got it. The "older blocks" from hive will be kept as it's doing now, but Lite Nodes will do parallel transactions and then upload it to the "main" Nodes, right? That way they'll be faster because they don't need to keep all the chain of blocks updates only what they are focused doing... 🤔
