Ever wondered how do nodes find each other on the Bitcoin network? I assume most of you didn't hear about seed nodes / DNS nodes.

These nodes are run by trusted members of Bitcoin devteam. These servers are the gates before entering the network.

Is there any risk of disruption? I assumed cryptos were by design completely trustless. Meaning youd need to pull the electricity to take it down, that's how robust I assumed it was. Cuz even theres a node on a Satellite.

Now a human built design when it comes to money will be trident tested. This feature seems like the human element. And going by Murphy's eventually there will be a hickup somewhere.

As I learnt about ICANN and IANA where IANA to this day is responsible for the root zone getting signed each month for the internet to "run" this had me wondering that if a big enough nation would go after Bitcoin wouldnt this seed node part be a surface of attack?
