Bip47 & Reusable Payment Codes version 3 & 4

[yoshimo]

Since we are getting closer to TOR Support, it would be great to get additional support for privacy enhancing features.
Colloquial, PayNyms.
These are specified in Bip47 as implemented by Samourai and enhanced in https://github.com/OpenBitcoinPrivacyProject/rfc/blob/master/obpp-05.mediawiki
Having more wallets support this venmo style method for sending money to your friends, would benefit the ecosystem in general.

[apemithrandir]

Just loaded up the apk from the PR and got myself a blue wallet payment code. Once I get some sats on the wallet I will pay that bounty.
Next step is to link BlueWallet up with http://paynym.is and get me my little robot avatar 👍
Also managed to connect to my own node before generating the wallet for that extra touch of class.

Any plans to add any of these features that Sparrow has:
https://sparrowwallet.com/docs/spending-privately.html
Such as collaborative transactions etc?

[apemithrandir]

How do I use BlueWallet to send to @abhiShandy 's payment code?

[abhishandilya]

You can't send using payment codes, just receive from it right now

[apemithrandir]

You can't send using payment codes, just receive from it right now

I guess it wasn't explicitly stated anywhere in the thread above but I was assuming sending and receiving via payment codes. I will send half of the 1m Sats I pledged but I won't be able to use BlueWallet to send it to your payment code. I will have to use Sparrow.

I do not know what other bounty pledges will do. We shall see what they assumed a full implementation was.

[apemithrandir]

Also I am gonna have to put an expiration date on the remaining 500k of my bounty: Block Height 807,708 (approx 6 months)

Can't be leaving a Bitcoin denominated liability out there with no time limit!

[abhiShandy]

Sorry for the confusion. This is the first iteration. Sending should be implemented in the next one. Having an expiration date is a good idea. This GitHub issue has been lingering for too long.

Thanks for sending half of your pledge.

[coinsurenz]

Haven't been able to keep up with developments here but understand this is in beta? once deployed for all and sundry please tag me here & dm/mention on twitter (same handle) if you dont get a prompt response as my github notifications tend to be pretty cluttered

[jordan-bravo]

Subscribing to this issue to be notified of updates.

[apemithrandir]

We have passed the Block Height on my remaining half of my bounty.
Can I confirm that you cannot both send and receive to a payment code?

[abhiShandy]

That's correct. We can only receive using payment codes. There has been a few bug fixes and UX improvements on the receiving end.

Is there ongoing work on the sending part? I'd send my bounty with BW :)

[mateusdeap]

Where's the PR for this? Both PRs linked have been closed...

[pointbiz]

https://twitter.com/BtcCuracao/status/1783705971363025290

19,500,000 sat bounty from me.

19,500,000 sat bounty from me.

This task has become harder. You cannot rely on Soroban communications anymore.

[Overtorment]

work is being done to add support for sending to barebone payment codes (not paynyms)

[killer21m]

I was asking for some support with this feature here:

#6663

The only response I've got so far is from a scammer trying to steal my seed.

[apemithrandir]

This work is completed now, correct?
Who completed the required work?
I may or may not still honor my 500k bounty which expired over 50k blocks ago.

[pointbiz]

I see this bounty has been fulfilled and I would like to pay it out. Thank you, from all Canadian Truckers!

I understand the developer was: Overtorment
Reviewers: limpbrains, marcosrdz, BenWestgate

Overtorment can you provide a Bitcoin address or payment code?
Reviewers can you provide Lightning addresses?

[DeMonkeyCoder]

Hi
Glad to see this feature is finally merged and live!

This bip47 library developed by @zkfriendly is used in the development of this feature:

BlueWallet/class/wallets/abstract-hd-electrum-wallet.ts

Line 2 in 5cb3aa1

import BIP47Factory, { BIP47Interface } from '@spsina/bip47';

So we'd appreciate it if the supporters of the bounty also consider donating some BTC to the donation address provided in the README of the repository 🙂

Thanks for your hard work! @abhiShandy @Overtorment

[Overtorment]

i also enquired HRF about the bounty, waiting for a reply. If paid out, it will be distributed to everyone involved, starting from the awesome lib author

Yes! Thank you, I see the address in the readme. My intention is to split my bounty with everyone involved. I will wait to get the addresses from the other developers.

[yoshimo]

i would appreciate payment codes to be listed by the project owners themselfes so nobody can come in and snatch the rewards

[abhiShandy]

Here's my payment code:

[Overtorment]

@zkfriendly can you pls post your paymentcode?

[zkfriendly]

Here is my payment code: PM8TJLSPLroADRS1hJafJEUmRvuXZpE2YmRrfHT1LrYmQW6t4ZxtP73sjh5qUmxMMrpsioFHxaHFpGgkHz5Ubidyzc1orYjcAWYzdA71RVZshdytY67m

[DeMonkeyCoder]

Hi @Overtorment,
Did you also post your payment code somewhere?

[Overtorment]

Some donations were just distributed.

If anyone pledged sats and havent sent them - please split them between 3 listed payment codes (zkfriendly, abhi, myself)

I initially pledged 19,500,000 sats. I decided to donate 16,680,000 sats to each developer zkfriendly, abhiShandy, Overtorment totaling 50,040,000 sats.

I'm super thankful to have this contacts functionality and I'm already using it in the real world. You folks are amazing!
