Coinbase just deplatformed me likely because of my work on Bitcoin privacy. Last time I used @coinbase was perhaps in 2014, well over a decade, so they can't really claim I misused their service.

I held back writing this rant for 3 years, because 1. I considered Yuval (nothingmuch) my best friend when I worked with him and letting him go was the second hardest decision of working on Wasabi. (The first was of course the blacklisting.) 2. I considered it unprofessional for an employer to publicly share the issues with an employee. However many people took my silence for something else for what it was: good will, while Yuval has been ranting publicly ever since in bad faith, and at this point people keep taking his words at face value like claiming he left the project at his own decision, because of "his concerns with the project." Meanwhile blocking everyone he worked with, so nobody can contradict his claims. Today I'm going to address the circumstances of his departure. If you ask why don't I address X or Y? It's because when it comes to Yuval, nothing is simple and even why this single claim is so misleading requires a long explanation. Quick Context: I founded Wasabi Wallet and scaled the project up to 50 contributors and to a monthly bitcoin volume of 10 thousand bitcoins. However for over a year now I am not working on the project anymore and the past year, zkSNACKs, the company behind it has closed its gates as a result of the recent crackdown on privacy projects. The software right now is developed the same way as Bitcoin Core is: by open source contributors. (Qucik contrast: the ones who tried to be our competitors are in jail right now.) Firstly, Wasabi 2.0 was conceived by me and I started the research with Aviv, a mathematician. Later on Yuval (undoubtedly a genius, a linguist by training) and Istvan (PhD cryptographer) joined and Aviv left (his other company's offices were raided by the Matrix, so he was too distracted to continue the work with us.) The Wasabi 2.0 research consisted of 2 phases: one about amount organization and one about how to do that trustlessly. Logically you'd first figure out how to do amount organization and build a protocol that fits it. Yuval however "had many ideas" about amount organization and couldn't come to a conclusion on any, meanwhile Istvan figured out how to do a protocol that can organize any amounts and so the WabiSabi whitepaper was born. The plan was that me and Istvan build the cryptography, and Yuval focuses on the amount organization. We started pair programming on it, however Yuval got in our way, but he couldn't explain why what we were doing was wrong. IMO he just found a cool thing, I think it was called the STROBE protocol which was a general way of doing the crypto for WabiSabi, because in the future we can do all kinds of cool crypto magic with it (we never did.) Alright, so I wasn't gonna implement something I don't think it's necessary and results in significant added complexity in a critical part of the codebase, but he seems really eager to do that, so I got out of the way. Shortly after Istvan gave up working with him. Then Lucas, who was the first developer on Wasabi after me, implemented it with Yuval, because Yuval couldn't write C# code. Then again I was gonna write the non-crypto related protocol, but Yuval got in the way again, so a team formed: Yuval, Lucas and David, (at the time the CTO of Wasabi) to do it. At the end of it David also gave up working with Yuval. Aviv in the meantime came back, but has quickly been chased away by Yuval's unreasonableness as well. Note that at this point we were 1.5 years behind the 6 month timeline I was originally planning for Wasabi 2.0 and for a year already I was holding my back on every single board meeting blocking the management from firing him. What about the amount organization part of the problem you may ask? Well, Yuval has been claiming he has it figured out, yet nobody can get it out of him. Meanwhile I have already built the amount organization based on what I was able to gather from his walls of never ending texts and 5-8 hour long meetings with him. (It is not an exaggeration!), preparing in case he's gonna come short on the matter. Another half a year has passed and we were not able to get Yuval deliver anything useful, just keep getting his promises. At one point when he said "he can explain, just can't code it" I got him to record 12 minutes of explanation and spent with multiple people multiple days trying to decipher what he was trying to say. We even hired someone just to help him get his thoughts organized. Then he finally created some pull requests. Unfortunately they were terrible. Not just nobody understood them, they didn't even work. Then he refused to address the reviews, coming back with walls of texts for each suggesstion no matter ho minor they were. And then, finally we few him to Hungary, maybe he can deliver together with the team in person. After his trip I was disappointed that he didn't progress with the software with the team, but I got the impression everything is on track now, we understand each other and he understands he is expected to deliver. He did not, instead a few weeks later he wrote a long rant about all kinds of long forgotten issues he had years ago. At that point we were 2+ years late with delivering Wasabi 2.0. The UI team was so bored by then they completely rewrote the UI for it. Which was badass btw. Still the best non-custodial Bitcoin wallet UX for desktop in existence. Nevertheless, Lucas, who was the last person still willing to work with Yuval at that point gave up on him and said "I don't think we're ever going to come out with Wasabi 2.0 with nothingmuch around." This was the point where I realized we need to let him go. However I wanted to address his wall of rant fair and square and it took me a few days to write a response. Unfortunately during that week he has got into fights with a bunch of other people (Rafe, Max, Vlad) and by the time I was gonna respond to him, he had something akin to a bipolar episode, so I kept it short and didn't want to start a shitstorm and I didn't even have time, because him coming short meant I'll have to finish up the Wasabi implementation. Thus I let him go with a VERY generous compensation, (despite the board not approving it!) I thought he'll calm down after a few months or years and we can talk, but he's still stuck in the past and spiraling out with his public rants with claims increasingly disconnected from reality. This episode, I consider by far the largest of my professional, as well as personal failures. When the time of ideas has passed and the time of action arrived, I wasn't able to keep our resident genius productive anymore.
