Satoshi Nakamoto’s disappearance: the last posts, the last emails and the handover

The last public words were about software, not goodbyes

Satoshi Nakamoto’s final stretch on the Bitcoin forum reads like any other week. On 11 December 2010, in a thread about a PC World article, Satoshi wrote that it would have been nice to get the attention in any other context, and that WikiLeaks had “kicked the hornet’s nest.” The article had tied Bitcoin to WikiLeaks, and Satoshi plainly did not want that kind of attention yet.

The next day, 12 December 2010, came the last post in the cited BitcoinTalk account history. It announced version 0.3.19, a quick build adding some limits against denial-of-service attacks, meaning floods of junk traffic meant to overwhelm the network, and removing a “safe mode” that had been a stopgap after an earlier bug. Satoshi noted there was more work to do on that front. There was no farewell. The post is a maintainer shipping a patch.

You can read the whole run of posts in this site’s Satoshi correspondence library, which sorts them by topic. The published sequence documents continued maintenance near the end of that account’s activity; it does not establish a private plan or motive.

A week later, Gavin Andresen took the wheel, “with Satoshi’s blessing”

On 19 December 2010, seven days after Satoshi’s last post, Gavin Andresen opened a thread called “Development process straw-man.” Its first line: “With Satoshi’s blessing, and with great reluctance,” he would begin doing more active project management for Bitcoin. He proposed a staging tree on GitHub, pull requests discussed and merged on consensus, and a master branch built and tested before releases. It is the ordinary machinery of an open source project, and it was new to Bitcoin.

Andresen was by then a regular contributor, and our profile of Gavin Andresen covers how he got there. What matters here is timing: the handover was public, and it happened while Satoshi was still reachable by email.

“I’ve moved on to other things”: the April 2011 emails

The clearest statement of departure came in private. Mike Hearn, a developer building a Java version of the software, had been emailing Satoshi about a technical idea. On 20 April 2011 he asked directly whether Satoshi planned to rejoin the community at some point, for code reviews perhaps, or to step back from the limelight permanently. Satoshi’s reply, dated 23 April 2011, is the last email Hearn received: “I’ve moved on to other things. It’s in good hands with Gavin and everyone.”

The rest of that message is about Hearn’s project, BitcoinJ, and why a simpler client would help new users get started. It is generous and practical, and entirely unsentimental. Hearn later published the exchange in full.

Three days later, on 26 April 2011, Satoshi wrote to Gavin Andresen. Andresen had been describing Satoshi to the press as a mysterious figure, and had mentioned an upcoming talk at a conference for US intelligence agencies. Satoshi asked him to drop the mystery: the press, he wrote, just turns that into “a pirate currency angle,” and it would be better to talk about the open source project and give contributors credit. As far as anyone has said publicly, that was the end of the correspondence.

The keys changed hands: the alert key and the lead developer role

Bitcoin had one piece of central control in those days: an alert system, created by Satoshi, that let whoever held a particular secret key broadcast a warning message to every copy of the software. It was meant for emergencies. Holding that key meant holding the network’s megaphone.

Court findings in the 2024 Crypto Open Patent Alliance case set down the handover as uncontested history. In around April 2011 Satoshi delegated the role of lead core developer to Andresen, and on 26 April 2011 Satoshi “transferred a file containing the network alert key to Mr Andresen.” Reporting based on Andresen’s own account adds that the key came in a separate message, on its own, without comment.

The alert system itself was retired years later. Developers came to see it as a large source of centralization, and its final message was broadcast on 19 January 2017. Bitcoin Core 0.14, released that March, hard-coded that final alert. The megaphone Satoshi handed over no longer exists.

Mining attribution cannot locate Satoshi

Lerner’s 2013 early-mining analysis reported a large apparently unspent set and tentatively connected it to Satoshi. It did not prove the attribution. A historical spend observation also cannot establish whether keys exist today.

An apparent movement from a classified output would establish a transaction, not automatically the identity or circumstances of whoever authorized it. The Patoshi entry keeps those distinctions explicit.

What the silence does and does not tell us

Satoshi never explained the departure. “Moved on to other things” is all there is, and the timing lines up with two pressures: a surge of unwanted attention around WikiLeaks, and a project that by then had other capable hands. Anything beyond that is guesswork, and this site does not guess about people.

What the record does establish is an orderly exit. The last public post shipped a patch. A successor was named in public with Satoshi’s blessing. The one central key was handed over. Then the emails stopped. Whoever Satoshi was, they built something meant to run without them, and then proved it by leaving. For what is known about the person behind the name, see who is Satoshi Nakamoto, and for the wider evidence trail, the origins dossier.
