While installing some package in my Arch Linux system, I noticed certificates import operation that added 157 new CAs, that is strange for me:
Synchronize local certs with certs from local Linux trust store.
What are these certificates and why do I need them? Why mono package imports them and from where (it says, "local Linux trust store")?
Here is the log with certificate names from pacman -S output.

I am interested in for what these certificates and who maintains them. There over problem is that I cannot find an answer how does pacman package signing verification works and is it vulnerable to MITM attacks when running package list syncing.
