Thank you for your answer. I’m afraid to connect to Tor since I watched and read stuffs about the darkweb, there seem to be a lot of illegal and immoral stuffs in there. Don’t want to get involved in there. Is there any risk for running a bitcoin node without tor? And any benefit running it with tor?

Thank you for your answer. Is there any security risk if I expose my IP address with my transactions? I think I have been exposing my IP addresses with my transactions using bluewallet, electrum, etc without tor. Should I create a new wallet?

(Asked by: username_0 on 2021-08-27)

I always wanted to run a bitcoin node at home. But I always worry because it is related with bitcoin (BTC has value).
I have been broadcasting my transaction using Bluewallet by scanning qr code, or copy pasting a signed transaction string. I am wondering if there is any security risk in doing so. From here I thought it's better to set up my own node just to broadcast transaction using sendrawtransaction
So I have some questions on what I am about to setup.

Is this bitcoin.conf secure for the purpose?

# JSON-RPC

As I disabled rpcssl on my bitcoin.conf, is it secure to sendrawtransaction without SSL?

Is it more secure to broadcast transaction using sendrawtransaction on my private node? Or is it better to do it on public nodes like bluewallet, or sites like pushtx.com or sites lsited here: https://en.bitcoin.it/wiki/Transaction_broadcasting

What are the possible security risks of running own node at home?

What are the possible risks on doing sendrawtransaction from private home bitcoin node? Also the risk for doing it from public nodes?


Thank you in advance
