 Dear nostr,

I AM WORKING ON BIP-352 SILENT PAYMENTS FOR  @SeedSigner!!

https://v.nostr.build/8GEda.mp4

The UI took longer to build than the actual #bip352 code!

Caveat: I don't actually really know what I'm doing, so if you're BIP-352 savvy, see if your results match mine:

 Amazing!!!!

Love to see Silent Payment stuff being built!

Have a good one 🧡⚡

 Awesome, now we just need a non shitcoin focused coordinator software to match this. So far I've only seen Cake wallet implement silent payments.  
 🤙 
 can you please explain how silent payments work in simple words? i'm reading bip352 and it's getting a bit confusing. thanks! 
 BASIC SCHEME


The recipient publishes their silent payment address, a single 32 byte public key:
X = x*G

The sender picks an input containing a public key:
I = i*G

The sender tweaks the silent payment address with the public key of their input:
X' = hash(i*X)*G + X

Since i*X == x*I (Diffie-Hellman Key Exchange), the recipient can detect the payment by calculating hash(x*I)*G + X for each input key I in the blockchain and seeing if it matches an output in the corresponding transaction.

 Thanks for that explanation 👍 
 Someone sends funds to an address only you can accept. Only they know it has been created and funded though.

You scan the network for payments to addresses that could only have been created for you.

When you find one, you check its balance and add it to your wallets balance.

It's like Someone releasing a "message in a bottle" into the ocean with a message in a language only you in the whole world can understand.
Someone else can find the bottle and look at the message but it will be gibberish to them. Only the intended person (you) can read it.

 Do you use it? 
 I haven't yet. None of the software coordinators I use support it yet. But I'll do some tests with Silentium.

 LETS GO 🔥🔥🔥 
 why are u now promoting this ? wierd time to promote this.  
 What's weird about it?

Sounds like you're implying that something shady is going on. So let's hear your conspiracy theory then. 
 its curious that they choose to promote this product in this date and state. Why not wait 3 more month when really ready ?

Samourai wallet get to court ==> kyc everywhere ==> bisq and any gov sponsor tied are ready for the next gen steath tech. Its definitively curious and easy to get XD.

 Who is "they" you refer to in the first sentence? SeedSigner? Bitcoin Core?

What is "this product"? SeedSigner? The silent payments protocol itself?

"...are ready for the next gen stealth tech." Wait, that's a BAD reaction to the government cracking down on centralized privacy tools? 
 They is anyone who try to stand between people and call himself essentiel "middlemen" 

product is an addition of all those things. Seedsigner and silent payment is a product.  
 "They" are irrelevant for SeedSigner since you can build it yourself and run the FOSS code completely permissionlessly. Those of us involved in the project have NO IDEA who has built a SeedSigner.

I disagree with your definition of "product". I think of a product as something that a company sells. We're a completely open source PROJECT. If you build a SeedSigner and run our code, none of the volunteers who work on the project profit from it.

SeedSigner + Silent Payments is a FOSS project adding (currently experimental) support for an open source protocol / technique.

No one asked me to start building support for Silent Payments in SeedSigner. No one paid me to do it.

I've spent quite a bit of time with bip47 in the past. Interest in bip352 is a natural progression.

Some conspiracy theories are interesting or incisive. This one isn't. 
 So no conspiracy going on ? all is legit and clean ? XD  
 Yeah. Don't take my word for it. Anyone who knows me can tell you that you have a really dumb take here. 
 Is not about knowing someone anymore. And if u and ur friends telle me that im dumb good for u. No failing for that midlleman.  
 UI is hard.
