The X Post with some of the source links (and a couple typos corrected). It’s not all I have on each as I’ve been collecting hundreds of materials, so this is just for quick reference. I also did not anticipate an audience of more than the usual 50 people or so reading my post as I’ve been researching this for about a year in the public eye and even tagging Jack in a few. If a link is broken, let me know as I’m away at a conference this week and rushed to fill these in for those interested. Like I said, this is not all I have.
Here’s that post with links filled in
Jack Dorsey was:

Still on the cypherpunk mailing list in 2000 under his dnet .com email

Subscriber to cryptome .org in 2001 (visible in his bookmarks)
Made a blog post where he jokingly says he is working on a network for drug traffickers. (image) (source)
Posted a bio in 2003 that says he is into crypto, pseudonyms, 4am hacks, and more
Posted in 2003 that he is ending his dependence on the US dollar and creating a barter network
Referred to himself as Jak instead of Jack. Jak was his pseudonym.
Jack, who was a sailor, tweeted on 8/17/08: “Around the horn and home again, for that’s the sailor’s way”. Bitcoin .org was registered the next day.
Jack’s twitter profile from Sept ’07 – Jan ’09 said he was a sailor.
The original Bitcoin source code included an old sailor’s adage. “Never go to sea with two chronometers; take one or three.” (source 1), (source 2), (source 3)
The original Bitcoin source code documents are all timestamped as being created at exactly 4AM, just like Jack’s bio. (One person has said that early tarballs of this era unpack with 1am timestamps. The few I have found from that era unpack with 4am timestamps which might indicate a timezone conflict).
The original Bitcoin source code documents contain a brute forced example vanity bitcoin address that starts with NS17 (Nakamoto Satoshi 1/7 ). The documents were created 1/7/09. (source 1), (source 2)
Satoshi accidentally logged into IRC on 1/10/09 using a real IP, revealing he was in California (where Jack was). This is sourced from old information and debates. (1), (2)
The first bitcoin transaction took place on Jack’s mom’s birthday (1/11/09)
Satoshi joined the bitcoin forum on Jack’s birthday (11/19)
Satoshi’s last mined block was on Jack’s dad’s birthday (5/3/10)
Satoshi sends bitcoin to 4 addresses after Hal, including one that has jD2m in the middle.
Jack lived at 2 Mint Plaza in San Francisco. Jack Dorsey 2 Mint (jD2m). Plenty of sources but here’s some 1, 2, 3
Satoshi tells Martti Malmi that he is really busy with work. Jack was busy launching his next startup, Square (now Block). June 14, 2009, July 21, 2009, May 16, 2010
Satoshi tells people on the forum not to donate Bitcoins to Wikileaks on 12/5/10
Twitter is hit with a secret court order with a gag requirement to turn over everything it has about Wikileaks on 12/14/10
Satoshi stopped logging into the forum on 12/13/10 and never returned
Jack is made Executive Chairman of Twitter while remaining CEO of Square on 3/28/11 and he tweets that he is very busy with both
Satoshi sends his last email on 4/23/11
Twitter’s tech lead suggests that Square might integrate bitcoin payments on 5/23/11
Jack Dorsey calls Bitcoin an Amazing Movement in September 2012 and said that Square would accept it if it became huge and accepted.
Jack’s best friend Alyssa Milano writes a novel (Hacktivist) in the Summer of 2013 about Jack, in which she places him as living a double life behind a famous pseudonym
Square announces Bitcoin acceptance on 3/31/14.
Satoshi’s gmx email is hacked on 9/8/14 and the hacker attempts to extort Satoshi by sharing that he knows about his connection to St. Louis, Missouri. Jack is from St. Louis. 1, 2
Alyssa Milano writes a 2nd novel about Jack (Hacktivist 2). In this one, Jack’s famous pseudonym is hijacked and his software developed in a way that was not intended. The hijacker has a logo that looks almost exactly like Gavin Andresen’s Bitcoin Faucet logo. It was released in installments with the first one going out on 7/29/15.
Two weeks later on 8/15/15, Satoshi reappears on the bitcoin mailing list to address the bitcoin block size debates. People are shocked about Satoshi’s return and some doubt it is really him but could not disprove it.
On 10/15/15, Jack is made permanent CEO of Twitter, officially making him CEO of two companies.
The last installment of Milano’s novel about Jack is published, in which its ends by him returning as head to his social network.
On 4/20/20 Lex Fridman asks Jack if he is Satoshi, to which Jack tells him that he wouldn’t admit it to him if he was.
“No, if I was, would I tell you?
This is in contrast to Nick Szabo, Adam Back, and Hal Finney all saying explicitly that they were not Satoshi.
On 5/25/20 – 145 very old bitcoin addresses signed a message stating that Craig Wright was not Satoshi and that he was a liar and a fraud. The oldest bitcoin address that signed the message started with 1jak (Jack’s old pseudonym) and the newest that signed it contained HiSQ in the middle. SQ is the ticker for his company Square. 1, 2
In February of 2022 Jack starts wearing a Satoshi shirt, first on a Michael Saylor podcast and then at the Super Bowl.
On 10/27/23, Jack said at a conference that “Bitcoin and Satoshi in 2009 was a combination of my childhood and my curiosity and everything that I aspired to be and everything I loved.” – lots of commentary on Satoshi here. Watch all of it.
Craig Wright’s attorneys argue (1, 2, 3) in early 2024 that if Craig Wright was not Satoshi “then the real Satoshi would have been expected to come forward to counter the claim.” It did not dawn on them that the person countering the claim was Jack Dorsey, who was the basis for the COPA v Wright legal challenge to begin with. Jack Dorsey came forward to counter the claim.
On 7/21/24 Jack wrote on Nostr, “I frequently imagine Satoshi sitting back somewhere and laughing at it all.”
On 8/28/24 Jack went on Nostr and thanked Hal Finney (now deceased) for his help.
Jack parades himself around in a Satoshi shirt.
———-
The belief that Satoshi never wanted to be found is something that other people invented about Satoshi. Satoshi chose pseudonymity, not anonymity, as Jack so pointed out in a podcast with Lex Fridman. The reason why Jack would do all of the above, while not directly admitting it, is because Satoshi and bitcoin are his art. And it’s a masterpiece.
