Now that i know there are open-source secure element, why don't Ledger migrate from closed-source to open-source secure element? Do they find secure element they currently use is more secure than all open-source secure element?
Apparently it is a question of security. There was some talk that they would create a new open sourced chip, but I don't know what happened with that. There is an old reddit post from one of their team members that mentions that Ledger feels that there are currently no open-sourced chips that can be compared with closed-source chips in terms of security.
I just meant that today there are no open-source chips that can offer the same level of security as the closed-source chips. However, it is Ledger's intention to open-source as much as possible, but existing constraints within the chip industry make this a slow process.
