Debunking Jameson Lopp’s Rebuttal on the ‘Jack Dorsey is Satoshi Nakamoto’ Theory

Back in February 2025, prominent Bitcoiner Jameson Lopp attempted to debunk the theory that Jack Dorsey was Satoshi Nakamoto. Unfortunately, almost all the information he relied on for his arguments were either wrong or required leaps of the imagination. While I addressed this immediately after he posted them here and here, they’re being republished here:

Lopp: “During the time period of 2009 & 2010, Jack Dorsey was not only Chairman of the Board of Twitter, but also the CEO of the fledgling startup Square. It’s quite clear that he was an extremely busy person not only overseeing multiple companies, but traveling around the world meeting important people, doing press interviews, speaking at conferences, promoting philanthropic causes, and more. His activities do not fit the profile of someone who had the time and mental bandwidth to also be building a completely new financial system from scratch while maintaining perfect anonymity.”

Counter:

Twitter: Jack was fired from Twitter in mid-October 2008. He was made “silent” Chairman with no active role in the company and did not return in an active capacity at Twitter until March 28, 2011. So there is no conflict with his role at Twitter as he did not have an official job function there during the time period in question.

Satoshi Nakamoto published the White Paper on October 31, 2008 and sent his last farewell email in April 2011. This reinforces the plausibility that Jack is Satoshi since Satoshi appears right after Jack leaves twitter and exits right as Jack returns to Twitter. Also, Jack published a reference to the name Satoshi in March 2011, showing that it had been the first tweet ever made by his best friend & love interest (Crystal Taylor) on the beta version of Twitter.

Square: Was Jack too busy launching Square? The company was founded February 11, 2009 and didn’t launch until December 2009. Coincidentally, Satoshi complained about being too busy with work during the same time period.

June 14, 2009 – Satoshi Nakamoto: “Thanks, I’ve been really busy lately.”

July 21, 2009 – Satoshi Nakamoto: “I’m not going to be much help right now either, pretty busy with work, and need a break from it after 18 months development.”

May 16, 2010 – Satoshi Nakamoto: “I’ve also been busy with other things for the last month and a half. I just now downloaded my e-mail since the beginning of April. I mostly have things sorted and should be back to Bitcoin shortly.”

July 8, 2010 – Satoshi Nakamoto: “I’m losing my mind there are so many things that need to be done.”

August 27, 2010 – Satoshi Nakamoto: “Sorry, I’ve been so busy lately I’ve been skimming messages and I still can’t keep up.”

April 23, 2011 – Satoshi Nakamoto: “I’ve moved on to other things. It’s in good hands with Gavin and everyone.”

So if Lopp’s argument is that Jack would’ve been really busy with launching Square then Satoshi complaining about being really busy during the same time period actually reinforces the plausibility of it being Jack.

Lopp: “Jack Dorsey worked with the US Federal Government to visit several countries (Iraq, Mexico, Russia) on behalf of the US tech industry. Does anyone truly believe that Satoshi Nakamoto, who was extremely wary of gaining attention from governments, would be working directly with them?”

Counter: A lot of people truly believe Satoshi worked with the government or was the government. The characterization that Satoshi was “extremely wary of gaining attention from governments” is not based on anything, unless he was referring to the incident in which Satoshi advised people not to donate Bitcoins to WikiLeaks. That incident ironically makes it more plausible that Satoshi was Jack Dorsey because Twitter received a secret court order regarding WikiLeaks (December 14, 2010) a day apart from Satoshi’s last activity on the Bitcoin forum (December 13, 2010). Square was also courting a relationship with Visa, which had made it a policy to restrict funds to WikiLeaks. The Square / Visa partnership was announced on April 27, 2011, four days after Satoshi’s last farewell email.

Lopp: “The first version of the Bitcoin software was Windows only, meaning that Satoshi developed it on Windows. I’m sure Jack used Windows at some point in his life, but he has been a die-hard Apple fan ever since the original iPhone came out. You can find many posts where he refers to various Apple devices he uses. I personally recall speaking with him several years ago and learning that he doesn’t even use laptops or desktops, but sticks to iPhones and iPads. It appears that may have even been true back in 2010. While reading through his 6,200 tweets I saw many referencing Apple products but none regarding Microsoft or Windows.”

Counter: Windows had a 95% share of the entire desktop OS market in 2009. No serious developer that was planning to appeal to mainstream desktop users would’ve developed for anything other than Windows even if they were a “die-hard Apple fan.” Regardless, Jack used Windows, MacOS, FreeBSD, OpenBSD, Blackberry OS, and several flavors of Linux including Gentoo.

Lopp: “I think the best we can do is to show that the person was out and about doing things while Satoshi was known to be sitting at a keyboard.”

Counter: Lopp assumed that posting comments to the internet in 2009 and 2010 required one to be “sitting at a keyboard” despite Jack being a prolific Blackberry user (since at least the year 2000) and later an iPhone user.

Lopp says that Jack can’t be Satoshi because on November 27, 2009 Jack tweeted that he was furniture shopping with Alyssa Milano and that 35 minutes prior to that Satoshi posted to the forum. Not sure what this is supposed to imply. Satoshi can’t post to a forum and then go shopping? Have people never posted to a forum and then gone somewhere afterwards? Would it not be possible for Satoshi to post to a forum from a phone even if it means he did it while shopping? Ironically, I’ve posted previously about the possibility of Alyssa Milano specifically being in on the Satoshi secret. Not very good.

Lopp says that Jack can’t be Satoshi because on December 9, 2009, Jack tweeted that he was walking to meet the Mayor of Paris at City Hall (in Paris) and then 18 minutes later Satoshi posted to the forum. Lopp presumes that Jack was not capable of posting to an online forum while waiting at City Hall to begin the meeting. When did the meeting start? How long did he wait? People post online while they sit and wait for meetings. I have personally sat in government buildings and waited for meetings with officials and passed the time by posting to forums. Why is this considered to be impossible? Answering emails and posts is and was a commonplace thing to pass the time. Not very good.

Lopp says that Jack can’t be Satoshi because he attended a long company meeting on February 26 that ended at 10pm and Satoshi made posts on the forum at 6:17pm and 6:48pm. Okay? He couldn’t have posted before the long meeting? Pretty weak. Not very good.

Lopp says that Jack can’t be Satoshi because on May 20, 2010, Jack tweeted that he was in a car with his brother to go out to dinner with his family and 10 minutes later Satoshi posted to the forum. Was it Jack driving or his brother? Because if it’s his brother, then Jack can post from his phone to the forum while they’re driving. But if it’s Jack driving, then how is he also tweeting? Hmmmm…. Or did they get to the restaurant already and they are waiting and Jack is posting to the forum from the restaurant. I’m still lost on why Jack couldn’t post to a forum from his phone. Why are these things conflicts again? I myself was posting to forums from my phone in 2010. Not very good.

Lopp says that Jack can’t be Satoshi because on May 26, 2010 he tweeted that he was headed to meet Senator Cory Booker at 5:01pm and Satoshi posted to the forum at 5:16pm (with a file attached) and again at 5:34pm. Booker tweets at 7:32pm that he had just met Jack and Jack tweeted at 7:45pm that he had just met Booker. It seems like they actually met late then, perhaps around 7pm. Not sure why it’s considered impossible for Jack to say that he’s headed to a meeting and subsequently post to a forum (with an attachment) before actually being in the meeting itself, which doesn’t appear to have taken place for a while. Maybe Jack left later than he said he was leaving or maybe Jack got there and ended up waiting around for a very long time before the meeting and played on his phone and posted to the forum as people do when they’re bored. Not very good.

Lopp says that Jack can’t be Satoshi because on Saturday, July 10, 2010, Jack tweeted at 6:17am local time that he was getting ready to go on stage and present Square, followed by Satoshi posting four sentences to the forum at 6:36am local time, followed by Jack tweeting “Boom.” at 6:45am. (The screenshots says 9:17 and 9:45 respectively because they show my timezone) Lopp presumes that “getting ready” means that the presentation, which he believes to be at Square’s headquarters, was starting within minutes or seconds of that first tweet and that the subsequent tweet of “Boom” meant it was over. Satoshi posting in between these times therefore makes it impossible to be Jack.

This presentation was taking place at the Sun Valley Conference in Idaho, an invite-only event for major tech moguls. Jack was even at the Sun Valley on Ice show that evening. There is no evidence I have seen to suggest that “Boom” meant he had finished giving his presentation but Lopp needs us to believe that in order to create a conflict in the timeline to support his argument. Not very good.

Lopp points to the fact that Satoshi posted to the forum precisely during the short window that Jack was meeting with the President of Chile in Santiago on July 14, 2010. Satoshi posted at 9:10pm UTC time on the forum which would have been 5:10pm in Santiago.

Jack:
(1) says at 3:36pm that he’s on the way to meet him and that they will spend an hour together
(2) suggests that their meeting was already over by 5:03pm.

At 4:10pm a tweet goes out from the President’s account about their meeting. It does not confirm they are actually together yet even if it implies they are.

Satoshi posts to the forum at 4:25pm.

Jack signals the meeting is over with a tweet at 5:03. Satoshi posts at 5:10pm local time. While narrowly outside the perceived window, it is outside of it, and we don’t know when the meeting actually ended. It could have been over at 4:45, for example. A tweet at 5:03 doesn’t mean it ended at exactly 5:03.

It is well documented that Jack and the President met but it is not known for precisely how long. It could have been 10 minutes as these are how these things go, particularly with important figures like a head of state. Lopp takes the hour at face value and combines it with his belief that Satoshi did not have access to a cell phone in order to make his debunking work. Besides, couldn’t Jack have typed up his forum post prior to the meeting and then finally posted it after the meeting? Not good enough

On July 21, 2010, Lopp says that Jack can’t be Satoshi because Jack was at an Apple Store in Chicago where his company was hosting a demo of Square starting at 12 noon all while the forum shows that Satoshi posted at 11:07am and 12:31pm local time that same day. I’m not sure why Satoshi being in a computer store would imply it would be impossible to post a message from a computer or from a phone. The more substantive post of the two that Lopp relied upon was the one that was made an hour before the demo. For this to be a conflict, it would require Jack to literally be doing a Square demo himself during the exact minute of 12:31 when Satoshi posted. Not very good.

Lopp says that Jack can’t be Satoshi because on July 28, 2010, Jack was attending a baseball game while Satoshi was posting on the 28th. Unfortunately Lopp got the dates wrong. Jack was at the baseball game on the 27th, not the 28th, as evidenced by the 9:19pm PT tweet on July 27, 2010 that he uses as his evidence.

Lopp misread the dates.

Lopp says that Jack can’t be Satoshi because he tweeted on August 14, 2010 that he was walking to meet with Scott Harrison for lunch and that an hour and 18 minutes later Satoshi posted two sentences on the forum that he had solved an issue with compiling the Bitcoin software. Ok? Which means what? Which means we have to presume that Satoshi had been busy doing this work exactly during the lunch time window and then rushed to post about it immediately to the forum? Satoshi couldn’t have solved it earlier and then posted it on the forum later when he got around to it like right after a lunch meeting? Not very good.

Lopp says that Jack can’t be Satoshi because he tweeted on August 22, 2010 at 4:25pm that he was listening to music while on the highway when Satoshi posted to the forum at 3:51pm, 4:01pm, 4:21pm, 4:55pm, and 4:57pm local time. I like this one to Lopp’s credit because there’s a link in Jack’s tweet to a purported photo of Jack behind the wheel looking out through the windshield. And so the argument here is that Jack can’t be posting to the forum because Jack is too busy driving! But we only know this because Jack is tweeting! And with a photo too? So if Jack is really driving, he is still apparently capable of taking a photo while driving and tweeting while driving, which hurts the case that he couldn’t also be capable of posting to the forum. Or there’s the possibility that someone else was actually driving and he was busy posting to the forum from his phone. Or… that Jack actually made that tweet about being on the highway hours or days after it actually happened. Or it never happened at all and it was online content for engagement or a dream of something nice. But if we give this one the benefit of the doubt and say Jack was really driving at that time, we can’t ignore that the evidence of him driving is a result of him playing on his phone while doing it. These “conflicts” are not very good at debunking Jack as Satoshi because they require leaps of the imagination

Lopp says that Jack can’t be Satoshi because he tweeted on September 19, 2010 that he walked 1,256 steps in the span of 425 minutes and that Satoshi posted to the forum twice during this time period and made a code commit. I did the math and it seems 1,256 steps is only 0.6 miles and 425 minutes is over 7 hours. This seems to actually support the theory of someone sitting around all day and builds on the case that Jack is Satoshi to make the code commit. Not very good and even supports Jack as Satoshi

Lopp: “I find the aggregate of all the evidence to provide so much doubt that a reasonable person would conclude that it’s far more likely that Satoshi was someone else.”

Counter: Try again.
