h/t Dan Gould, here is a paper on UIH heuristics in payjoin:
Those two mobile phones controlled 7+ BTC together.

I'd love to know if any 'chain watchers' out there could update the now very-old stats that LaurentMT collected on UIH violation probabilities; see the definition of UIH here and Laurent's stats in a lower-down comment:
Looks like someone's been working on an experimental payjoin feature hooked up to lnd, nice idea:

Regulatory attention on Bitcoin & privacy techniques to counter
"Breaking the common-input ownership heuristic would be a crucial win for more fungibility in #Bitcoin :bitcoin:, and consequently for all other Cypherpunk properties."
"#Payjoin adoption made a big step forward when #JoinMarket and #BTCPayServer implemented it. If only a few more would follow, on-chain #privacy could benefit asymmetrically."

PayJoin adoption

Sparrow wallet looks like an interesting bitcoin wallet project:
https://sparrowwallet.com/docs/
They have payjoin/BIP78 support since 0.9.7 ; I'm not sure but I think they don't yet have receiving support, only sending.
Anyway it looks cool (some focus on coldcard support), but disclaimer I have not yet used it.
Learned of this via TFTC h/t @mattodell ;
https://github.com/armins88/Onion78
there's a short video demo and a slide deck, basically this is a mobile-to-mobile BIP78 payment implementation (interestingly, seems to be iPhone) using onion service for receiver as Joinmarket does. Was part of an MIT hackathon.
Most interesting if this BIP78 implementation makes its way into production mobile wallets, will be a great selling point ...
In this PR @kristapsk makes an interesting point (as best I understand it) - what if the receiver in a payjoin contributes an unconfirmed utxo? BIP78 doesn't mention it afaik. Perhaps something should be added in regard to this?
@NicolasDorier @kukks thoughts?
https://github.com/JoinMarket-Org/joinmarket-clientserver/pull/846#issuecomment-812549859
Finally how to receive a #payjoin from the @joinmarket QT GUI:
* Load and unlock a wallet
* -> Wallet menu -> Receive payjoin...
* choose the amount and mixdepth
* Generate request
* share the link or the QRcode
Sending:
* paste the payment link
* choose the mixdepth and start
Shall not stop there since it is even more fun the other way around.
Just sent a #payjoin from the @BTCPayServer wallet and received in @joinmarket.
See the guide for BTCPay: https://docs.btcpayserver.org/Payjoin/#paying-to-payjoin-as-a-user
for JM CLI: https://github.com/JoinMarket-Org/joinmarket-clientserver/blob/master/docs/PAYJOIN.md#receiving
(available in the QT GUI and #JoininBox also)
Having fun testing #payjoin-s on signet to a @BTCPayServer shop from a @joinmarket wallet.
Now can select a custom miner fee in the #JoininBox menu as well.
Transaction on @mempool:
https://mempool.space/signet/tx/63d56c2da7646891a503f39e339ce54fd7d37b285871d6c1df63aa24bcdaf19bn:
BTCPay test shop: https://signet.demo.btcpayserver.org/apps/3XRQQi3WhWZLX9yVGH5zAQJypXuC/pos
Been fine tuning some payjoin details in the JM code last week; it still tests out correctly with btcpayserver on mainnet, but I'd like to test either sender or receiver with one or two other wallets, does anyone know an example that's practical? ideally with signet support but I can do mainnet.

If you use a p2p exchange ask them if they'll implement payjoin.
