Nostr Web Client

Privacy on chain

If you use electrum public servers, the server will know your ip and all your balances.

If you use electrum servers over tor, the server will know that certain addresses belong to a single entity.

If you do either of these two things you ruin your privacy and your coinjoins.

You have only two options, either you use your own Bitcoin node to check your balances via RPC or with your own electrum server connected to your Bitcoin node.

Or you use Wasabi which offers block filtering through BIP158.

If you use hardware wallets never use the manufacturer's software if it does not allow you to connect to your node, use sparrow connected to your own node, trezor suite connected to your own node, green wallet connected to your own node or wasabi (the latter can also be connected to your own node but is not necessary because of the block filters).

Be aware that three-letter agencies have public electrum servers to collect data or may even have compromised public servers of companies like blockstream.

Take care of your privacy.

Wasabi has its own issues with censorship of UTXO and traceability, doesn’t it?

Cyph3rp9nk 1y ago

Wasabi no longer provides a coordinator, it is now a community supported wallet (there is no longer a company behind it) with good privacy features and HWW support to which you can add a third party coordinator (not supported for HWW).

Another good feature is that it does not allow you to add coordinators that charge fees, so coinjoins in the case of use only have the on-chain cost.

The most famous coordinator is Kruw.

Or you can run Monero over Tor.

Thanks for putting that into words. Just what I needed to advice a friend.

Is not nostr:nprofile1qqsrf5h4ya83jk8u6t9jgc76h6kalz3plp9vusjpm2ygqgalqhxgp9gpz4mhxue69uhk2er9dchxummnw3ezumrpdejqzyrhwden5te0dehhxarj9ekxzmnyqyt8wumn8ghj7un9d3shjtnwdaehgu3wvfskueq555fk2 doing the same as Wasabi with BIP158?

And you additionally have LND to use alternatively LN to enhance privacy over your UTXOS when coinjoins are not the best option (i.e. high on-chain fees)

Cyph3rp9nk 1y ago

Yes, but it does not support hardware wallets.

ZEUS 1y ago

Incorrect. We support HWW w PSBT signing and cameras

Cyph3rp9nk 1y ago

I was unaware of it, thank you very much for the information.

xiangcai 1y ago

i wasn't aware with that either. any article articulating this feature?

Andreas Griffin 1y ago

Yes, Electrum servers are a big worry for privacy.

Once Compact Block Filters are in bdk, Bitcoin Safe www.bitcoin-safe.org , will integrate CBF to get rid of the need for electrum servers.

Cyph3rp9nk 1y ago

Interesting, thanks for the contribution

Andreas Griffin 1y ago

https://github.com/rustaceanrob/kyoto is going to be compatible with bdk, and then I will integrate it ASAP.

Bitcoin Safe will be the first desktop wallet with CBF.

No configuration, no running a server, it will just work by talking to the Bitcoin nodes out there.

Wow fantastic 🙏

Run your node. Join a community of node runners. Not that hard to run a bitcoin node if you don't want to run lightning node.

Thank you for this information.

How to keep privacy using lightning network?

Cyph3rp9nk 1y ago

It is a complex issue but using Zeus and its LSP you have a lot to gain.

Dikaios1517 1y ago

Running a node is just one aspect of on-chain privacy, but it's an important one. That said, running it isn't enough, you actually need to use it when exploring the blockchain or mempool, and when using on-chain wallets by connecting them to your node.

I do take care of my privacy.. by using Monero when it's time to spend 😂

*ducks multiple inbound maxi daggers*

Saberhagen The Nameless 1y ago

Maybe I'm wrong, but don't electrum public servers use neutrino block filters for querying so won't know your balances?

Cyph3rp9nk 1y ago

Electrum does not use neutrino to query Bitcoin addresses.

Ok, folks, here I go again with #asknostr

I see all kinds of posts like this and I'm getting more confused by the day. I can't run my own node, I don't even have a computer. I already said it a few times, I am your proverbial normie, my gateway to the internet is a Samsung worth €120 when new. I buy Bitcoin for 10 - 20 Euro about 2 times a week, through the Lightning Network, with no KYC, from public ATMs. I really thought that I was careful, from my point of view, but posts like this worried me a bit. Just in case, I'm also very new. Less than 5 months on Nostr, even less on Bitcoin. Proverbial normie, proverbial blue-collar, etc.

So, do I need to worry? If yes, can you guide me towards an article for morons?

Many thanks in advance!
