KYC-free question

If your zapping wallet address is linked to your nostr profile, and you’re not using a nym, how difficult would it be to associate those sats (sent or received from that wallet) with your individual identity?

Curious 🤷‍♂️

I’m not going to say it’s not possible I’m not sure. But there is a big difference between KYC where zero effort is needed to track coins vs it maybe possible if someone had the knowledge, resources and a big enough motivation to find out.

That’s what I’m thinking in terms of general outcomes.

It’s not like someone’s needs to hack wallet of satoshi to figure out that I have a few thousand sats

Very different than an exchange that holds your home address along with how much Bitcoin you’ve ever purchased and transferred to your own wallets

Huge difference. Also in terms of legality how concrete would this be to prove they are yours, my guess is it would be difficult vs chainalysis tracking all your spends/ coin movements. I’d say the 2 are not in the same ballpark also generally you are dealing with smaller transactions over Lightning so not as lucrative as tracking big coin movements on chain. Reward of an attack is low compared to on chain.

Agree on all points. Add in the improved privacy/obscurity that LN introduces and it seems quite solid

There’s really no full anonymity with bitcoin since it is a public ledger but if used correctly it can be private and linking to identity can be hard to prove. If someone is looking for full anonymity then cash or Monero is probably a better option.

For sure. In my case, it’s primarily an exercise in understanding how it all works, and wanting to observe best practices

Maybe #[3]​ might know the answer to your OP?

The single best thing you can do is not consolidate UTXOs that aren’t already linked with common ownership. Ie don’t combine your KYC sats with you got from zaps. Or non KYC with KYC.

100% always mindful there 🤙

LN still has a long way to go for privacy, particularly for recievers, but as of last week, route blinding was introduced which will help a lot

It’s very difficult trace LN tx’s but there would be a record of it on Nostr. However, if you sent the tx from a wallet that’s not associated with your Nostr account, I would think that would also be very difficult to trace. It’s a good question.

In theory, with comprehensive data on Nostr events, and wallets linked to accounts, a highly motivated entity could associate transactions (and to some extent, balances) with non-anonymous individuals - right?

Mostly asking in order to develop my own understanding of how it all connects 🙏
