Someone asked me this question and I’m not 100% on the answer. Trying to verify it.

If someone is running a bitcoin node and their power goes out, will the node still be connected once it comes back on?

Any other implications of unexpected outages while running a node?

Thank you 🧡🫡

Yes, but sometimes bad things happen and you may need to edit some files to get it working again.

If it’s an umbrel, this helps. Different sometimes depending on OS. Not a fun time.

Been through it twice on different OS.

It should just download the latest blocks and keep on running once it powers back up.
