I have been listening to talk about lightning privacy from @supertestnet on Guy Swann and other places. Today, in the course of messing up one of my nodes, I discovered that Torq allows automatic transaction deletion for LND. This might be an easy privacy enhancement for the tech challenged like me. I think there are Start9 and Umbrel apps for the service.
I wonder if anyone has tried this?
Maybe is deleting only the logs, not sure if a successful payment can be deleted from channels database. See line 537 and 540 in lnd.conf https://github.com/lightningnetwork/lnd/blob/master/sample-lnd.conf#L537
maybe with the
prune_htlccommand can be done something, but not sure if this deletion is permanent.I see what you mean. So this is different from the plug in on CLN?
I don't know exactly the technical details, but just thinking about how a channel state works and the HTLCs, if you delete some pertinent data from history, it might be affecting the channel state. So that could trigger a force closure.
The channel state is like a private ledger between you and your peer (only), that is not broadcast yet. So any deletion in that ledger must affect the balances and trigger the penalty tx.
So I would be more caution with this stuff.
Deleting logs - perfectly fine. I always use that line in lnd.conf. Compacting database - good practice also
btw if you really want a "no trace" LN node, just use a disposable LN node (like Rizful). Use it, make your shit as you wish for a certain time and then dump it / forget it.
Thanks. While I was posting this I was in the middle of a very stressful mess with one of my nodes. I'll tell you about it sometime. It started when I compacted my database. I had no access to any sats for about four hours. I posted and zapped you with the little I had in an Orange Pill app! I learned a few major lessons today. Luckily it all worked out in the end. I need a beer and a nap.
