PayJoin is an exciting bitcoin privacy technology which has the potential to damage the ability of blockchain surveillance to spy on bitcoin users and destroy bitcoin's fungibility. A protocol standard has already been defined and implemented by a couple of projects such as BTCPayServer, Wasabi Wallet, JoinMarket and BlueWallet.
I've made a wiki page tracking adoption: https://en.bitcoin.it/wiki/PayJoin_adoption It is similar to the Bech32 adoption page. Recently a UK bitcoin exchange shut down due to new regulations, with the owner writing a very interesting and relevant blog post that I'll quote here: > you’re considered suspicious if you used a marketplace and not an exchange. Coinjoin counts as high risk. Gambling is high risk. As you use entities that are paranoid about keeping their coins clean and adhering to all the regulations, your risk scores will continue to increase and without you even knowing why, your deposits will become rejected, you may be asked to supply documents or lose the coins, your account may become suspended without you having any clue what you did wrong. And quite possibly you didn’t do anything wrong. But that won’t matter. > > The goal post, the risk score threshold will keep moving along this trend until the point where you will be afraid of using your personal wallet, donating to someone online, receiving bitcoins from anywhere except for regulated exchanges. At that point, crypto will be akin to a regular bank account. You won’t have a bitcoin wallet, you will have accounts to websites. https://blog.bitbargain.com/post/638504004285054976/goodbye If we want bitcoin to fulfill its dream of a permissionless money for the internet then we'll have to work on this. What can we do to increase adoption of PayJoin? _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
