Would Tor relays work in a dynamic manner switching from one to another from time to time? I am at the beginning of my research regarding a Tor network and I could use some support from you, guys. I would read a bit about entry, middle and exit relays as well as layers of encryption, but I need more realistic explaination how all of these operate in a practice. Thank you!
