Not completely positive how one can reply this query since I am undecided what you are making an attempt to attain. However from what I am studying, it seems such as you’re making an attempt to ship Bitcoin in a fashion which is untraceable in your system.
If that’s the case, then you definitely needn’t run a full node. Transactions are stateless, so so long as you have got the required data in addition to software program and/or libraries, you’ll be able to craft the transaction completely offline (on an airgapped laptop) .
You simply want:
-
Information of the non-public key
-
Pockets’s inputs
-
Information of the recipient’s deal with whom you need to ship it to
-
Software program or data of how one can craft the transaction and correctly serialize it earlier than signing
As soon as you have achieved these issues, you’ll be able to ship your transaction by means of to any node to broadcast it. The decentralized nature of the community makes it inherently troublesome for somebody to hint precisely which level your transaction entered into the community.
There are a number of totally different web sites you can use to stick your signed UTXO to.
Addressing the Node Challenge
Whether or not you employ your node or not, it should nonetheless be utilized by the community to relay transactions. That is how Bitcoin’s community works. So whether or not they’re your transactions or not, your node shall be relaying somebody’s transaction(s).
From what I perceive, node discovery is ephemeral to a sure extent – so when you ‘tear down’ your node, so to talk, friends will stop gossiping in regards to the existence of stated node as a result of it’s not a discoverable peer.
Concluding
It appears that evidently you are beneath the impression that you just should run a full node so as to ship a transaction autonomously and this isn’t the case.
In actual fact, in my view, should you’re actually seeking to ship transactions by means of to the community in a fashion that doesn’t reveal that you just ever transacted with Bitcoin, you’d be greatest off crafting your transaction offline completely, then discovering a web site someplace that lets you broadcast the transaction by means of their node (ideally through API if doable).
Doing this may be sure that your id stays protected.
If working a full node is necessary for you although for some cause, there’s actually no manner to take action in a very non-public method because the goal of working a node is to be discoverable by the community and help in relaying data to the remainder of the friends round you.
