What Does Privacy Mean?
We want encryption for trade. What is that?
In February 2009 Satoshi posted: “The root problem with conventional currency is all the trust that's required. … Before strong encryption… privacy could always be overridden by the admin based on his judgment call weighing the principle of privacy against other concerns, or at the behest of his superiors.” Since the people we do business with and often even strangers may override bitcoin privacy I have to ask, if communications privacy is protected by strong encryption, what keeps the transfer of value private? The other day, Max Hillebrand noted his “hope” that existing bitcoin tech has already achieved the same level of security in response to Satoshi’s words. Crypanalysis defines security against specific attacks a system can be proven to defend from. The tech on offer does not do this to my standard. I know we can extend that tradition and analogy to define the makings of secure value transfer and deliver it with guarantees.
Guarantee some Privacy
The most basic guarantee is to break the most common pattern strangers use to spy on bitcoin users. That’s what payjoin does, and why it fits into bitcoin exchange process to protect consumer privacy. This past week we drafted the the payjoin integration with bitcoin exchange software. The most advanced bitcoin exchange in Canada wants to upgrade first. There’s so much more here that I want to blurt out but I’ll keep it simple for now. If you want payjoin in software you use, have the developers visit payjoin.org and message me.
Interview Inbound
In a recent interview I got into the details of so-called “taint” analysis, how payjoin complements existing privacy tools, and the history and progress of bitcoin privacy enhancement. Stay tuned for the announcment.
Payjoin on iOS, Android, and MacOS
BlueWallet fixed payjoin in their latest release. The list of payjoin capable software continues to grow. Can’t wait to see who supports bitcoin privacy next.
Thank you for yours.
All the best to you,
Dan
