I looked at the onflow documentation and the three technical papers, but couldn’t find any information on delegation of stake and how key management for running a node of any kind works. I found this link https://docs.onflow.org/token/staking#delegation, unfortunately it looks like it was removed.
Thanks @jpzk for your interest. Our docs portal is still work in progress and we definitely aim to make it richer and easy to navigate. Thanks for the feedback.
Tagging @pete and @Tim in case they are aware of publicly available materials to share
