BTCPay server’s latest release offers Payjoin privacy feature (allows mixing unspent outputs)

posted 8 months ago
Payjoin(P2EP) support has been added in BTCPay’s latest release, sponsored by Blockstream. Payjoin (P2EP) is a form of coinjoin that allows 2 parties to mix their UTXOs while a payment is being done. Unlike other coinjoin mixing methods, a payjoin transaction does not leave a fingerprint and looks like an ordinary Bitcoin transaction.

Payjoin provides greater privacy for both parties:
-Sender – It can’t be assumed that all the inputs in a transaction belong to the same entity
-Receiver (merchant) – the UTXO set of the receiver does not grow with payjoin and blurs the link between sender and receiver for blockchain analysis software
