Mine experience is polo with non major brand logo and carrying a whole PC. If you come in a white work van, not a single person will question you, they will even open the door for you.

Also the protocol seems to be proprietary, which completely defeats the purpose of being decentralized.

I used to do work at a high security site. One day the fire department was there for inspection. Out of curiosity I asked the chief what happens if he needs access and he is declined it for whatever reason. He pointed at the truck and said “This truck along with it’s contents are the key to the city. Nobody can stop me”. That day I learned that nobody can stop the fire department.
