Instead, some of the companies using Liquid will act as as functionaries that validate transactions for each other using tamper-resistant hardware boxes with a special software stack embedded.

So Liquid has a software part and a hardware part.
After reading these informations, it isn't clear to me how these boxes work:
- Do they need to be updated?
- Do they need to be updated at every hard fork?
- Are them updated manually?
- Are them nodes?
- Are them connected to nodes? (even just one)
It seems that they support large blocks, but how and when it isn't clear.
