“Dana is a flutter app used for accepting bitcoin donations. It uses silent payments, a new static payments protocol, to receive donations while preserving on-chain privacy.” Anyone try this ? n...

Thanks for checking it out! We are really crap at marketing, but we are definitely looking for more people to try it out and give us feedback.

avoiding address reuse (in fact, making address reuse completely impossible, even for malicious users), is still a massive win for transacting on-chain. The extra cpu cost to scan for transactions is well worth that trade-off in my opinion.

Also, they named it "Silent" Payments and not Private Payments for a reason.. Don't think for a second that SPs are actually private. It's just a hidden link.

cygnet @cygnet 1779356280

the 'privacy' that silent payments offers is identical to a recipient handling out unique addresses to everyone, nothing more. it doesn't protect against any other privacy pitfalls.

Vitor Pamplona · 16w

Yep, unfortunately lots of people think its a privacy silver bullet.

Thank you sir, this is exactly what I was looking for.

cygnet @cygnet 1779246278

no problem. if you're using it to experiment, the '/tweak-index' endpoint may be more useful than '/tweaks' actually. The former returns all tweaks for that block, the latter will filter out all spent outputs (aka 'cutthrough' from the BIP)

#asknostr #bitcoin is there any public silent payment indexing servers running? I've tried to figure out how nostr:npub1lsrm8rdxzyhmumx5uzfmq47ta5ggdyns2xqkw0ej6h2qat026nvs7rm040 is doing it but I can...

you can use the blindbit-oracle server hosted on silentpayments.dev: https://silentpayments.dev/blindbit/mainnet/tweaks/900000

Frigate v1.4.0 has been released with significant performance improvements. It’s not just another release though. Here’s why: Silent payments is not just a new approach to static payment codes. I...

This is great, but I think saying 'catching up a few months takes an hour when on mobile' is a bit misleading I think. When I scan 1 year worth of transactions it takes me about ~5 minutes on my phone (doing 'local' scanning with Dana). Admittedly we use spent filtering, but that is described in the BIP too so I don't think it's unrealistic to compare it against that benchmark. '5 minutes' isn't *seconds*, but it isn't *hours* either.

craigraw · 23w

I measured the scanning performance on Cake, and estimated 2 years of scanning would take around 9 hours. Spent filtering makes a big difference, but it’s not appropriate for many clients, including Sparrow. Also the BIP approach requires non trivial data download which means making assumptions ...

As of today, what are the best wallets to send and/or receive Silent Payments? #asknostr

cygnet @cygnet 1764159231

Shameless self plug: for those interested in testing out a new silent payments wallet: check out Dana (currently only on android). We're working on giving users their own [email protected] bip353 address when creating a new wallet, that should be live pretty soon.

Pretty cool.

Minty Molyneux · 41w

That sounds exciting! 🚀 Silent payments and personal username addresses are a sleek idea, makes sending and receiving money feel way more seamless.

Yes. It refuses to sync past 912650-ish. blindbit oracle seems to return something that looks fairly common, altho maybe larger chunk thank usual.

cygnet @cygnet 1757237024

that's odd, i don't have any hangups myself, does it return a specific kind of error?

tsjk · 53w

It says "error sending request for url (https://.../filter/new-utxos/912660)". It's not always that number, but ish. Like it doesn't get past this particular batch.

The definition of 'node' is a little vague. I also consider bip158 ('neutrino') clients to be nodes, since they can independently verify their own transactions. But they don't really engage in stuff like forwarding unconfirmed transactions.

You can also run bitcoin core in pruned mode. In that case you drop block data that is irrelevant to you after verifying it, but other than that, you interact with the network in the same way that a full node would.

Thank you for the explanation. I think I might do that (pruned version). My node (knots on umbrel/ rasp. Pi) literally shit the bed over a power shortage (San Disk SSD apperently the real culprit) 2 weeks ago or I would send some zaps your way. Once it is fixed.
