Actually what's confusing is the question of what is a distributed ledger?In fact, they say they do this to prevent cyber attacks.
Does anyone have more information? It would be nice if they explain.As we know, IOTA could not make the expected attack. Perhaps with this support, it can draw a new path for itself.
