The Payjoin Foundation, focused on advancing Bitcoin privacy through open-source software, has been granted 501(c)(3) nonprofit status. According to NS3.AI, this designation allows U.S. taxpayers to make tax-deductible donations, providing sustainable funding for the development of privacy protocols such as Async Payjoin. This advancement does not necessitate changes to the Bitcoin protocol. Several prominent Bitcoin wallets have already integrated or support the Payjoin Dev Kit, enhancing user privacy while maintaining compatibility.
