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.

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 username@danawallet.app bip353 address when creating a new wallet, that should be live pretty soon.

if you're interested you can use blindbit:
https://silentpayments.dev/blindbit/mainnet/filter/new-utxos/900000
It might be too limited for your use case, since the filter only includes silent payments-eligible taproot outputs. But I thought it was worth sharing regardless.

Hi, sometimes there may be some random connection issues, but the app should automatically try again. If you try it now, does it still show errors?

some bip353 icon would be nice (a fancy '@' symbol or something?)

could you make an issue on github? let's continue the discussion there

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

what do you mean? with syncing Dana?

i don't think segwit had to do much with 'giving ground' as much as it was about balancing the cost of destroying vs creating utxos

just gotta increase that adoption

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.

either you run a node, or someone else does it for you

Comparing the effects on scanning for silent payments, with and without labels, using Dana.
(These are one-off measurements, don't take them too seriously)

I suppose a more accurate description would be 'pseudonymous', then? If you think of a silent payment address as a pseudonym for payments then these pitfalls are a lot more obvious.

2025-07-15 13:56:02 UTC

a low fee environment is pretty great for playing around with silent payments, all things considered

I just want people to send bitcoin to one another.

What network are you using on Cake wallet? Are these mainnet coins?

2025-06-03 21:45:44 UTC

- reply

I don't think it should be possible to send from Cake wallet to Dana, since they are on different networks. Does your receive address start with 'sprt1q'?

2025-05-06 01:03:35 UTC

Using Dana wallet, scanning from block 800.000 for incoming silent payments takes ~10 minutes

I think part of the reason is because the silentpayments module for libsecp256k1 is still under development. SP benefits a lot from the efficiency that module can provide, I see some projects holding off on implementing silent payment support until it's merged.
There's also just the general chicken/egg problem of sending/receiving support. Implementing sending is a lot easier, but there is no point if there's no good wallets to receive silent payments. And doing receiving properly, especially for mobile/light clients, is still just a lot of work.
