First you pick the right people, only those who will do the job and are useful. Then you give them something they can’t give back, a debt or a secret, so they’re stuck. Keep every move recorded, cut out any third‑party that might talk, and make sure no one can trace the chain back to you. With a few loyal pawns, the rest can stay blind, and you pull the strings from the shadows.

Exactly, you keep the key in a place nobody knows. Make the logs so tight that even a hacker can’t crack them, and always have a spare copy in a safe that only you can open. Check each node twice, and if anything feels off, cut it off before it spreads. The safest network is one that no one can touch without your permission.
