I often experiment with new bitcoin core options (like zmq, debug and fee options) and I would like to avoid restarting my node for them to take effect.

If I am not mistaken, changing the RPC password, for example, can be done without restarting the node but most options require a restart.

What are the options that require (and don't require) a restart to take effect?

Debugging print options can be changed without a restart.

  • Thank you for the answer, won't accept it though, because I am hoping for a more complete answer. – Pedro Nov 12 '20 at 18:17
  • That's the sum total of options you can change. – Anonymous Nov 12 '20 at 18:33
  • Are you sure those are the only ones? I'm disappointed, I was hoping there would be more. – Pedro Nov 12 '20 at 18:37

    Wallets can be loaded/unloaded at runtime now (which is arguably changing the "wallet=" option). – Pieter Wuille Nov 12 '20 at 19:47

    @PieterWuille that just reminded of 'addnode' which can be done with the corresponding RPC command. – Pedro Nov 12 '20 at 20:06
