On December 12, 2010, Satoshi Nakamoto, the pseudonymous creator of Bitcoin, posted his final public message on the BitcoinTalk forum. The concise yet weighty post centered on a warning: “There’s more work to do on DoS” (denial-of-service). After this, the inventor never again communicated publicly, cementing one of the greatest mysteries in the cryptocurrency world.
Satoshi's 772-Day Journey: From Whitepaper to Departure
Satoshi’s public activity began on October 31, 2008, when he published the Bitcoin whitepaper on a cryptography mailing list. Over the following 772 days (just over two years), he actively engaged with the early community, sending approximately 16 emails about the peer-to-peer electronic cash system and releasing “Bitcoin v0.1” on January 8, 2009, officially launching the network. Strong evidence indicates that Satoshi mined between 750,000 and 1.1 million BTC using a single high-end Windows PC. If he remains alive and holds those coins, he would be among the wealthiest individuals on Earth.
During his active period, Satoshi not only wrote code but also shared profound insights. He famously stated: “The root problem with conventional currency is all the trust that’s required to make it work. The central bank must be trusted not to debase the currency, but the history of fiat currencies is full of breaches of that trust.” He also expressed optimism about Bitcoin’s appeal to libertarians, though he acknowledged being “better with code than with words.”
“Kicking the Hornets’ Nest”: The WikiLeaks Episode
In 2010, WikiLeaks faced a financial blockade and considered accepting Bitcoin donations. While some community members welcomed the potential adoption, Satoshi vehemently opposed it. On December 11, 2010, he wrote: “No, don’t ‘bring it on.’ The project needs to grow gradually so the software can be strengthened along the way. I make this appeal to WikiLeaks not to try to use Bitcoin. Bitcoin is a small beta community in its infancy. You would not stand to get more than pocket change, and the heat you would bring would likely destroy us at this stage.” He added, “WikiLeaks has kicked the hornet’s nest, and the swarm is headed towards us.”
The very next day, Satoshi posted his final message. He released a quick build (version 0.3.19) and wrote: “There’s more work to do on DoS, but I’m doing a quick build of what I have so far in case it’s needed, before venturing into more complex ideas. […] Added some DoS controls. As Gavin and I have said clearly before, the software is not at all resistant to DoS attack. This is one improvement, but there are still more ways to attack than I can count. I’m leaving the -limitfreerelay part as a switch for now and it’s there if you need it. – Removed ‘safe mode’ alerts. ‘Safe mode’ alerts was a temporary measure after the 0.3.9 overflow bug. […] It was never intended as a long term feature.”
After this post, Satoshi never returned to any public forum. Despite numerous individuals claiming to be Satoshi, and occasional alleged emails, no communication has been verified as authentic. The December 12 post stands as his final goodbye.
Legacy and Reflection
Satoshi’s departure leaves countless unanswered questions about his identity, motives, and current status. Yet his technical legacy — the Bitcoin network — has grown into a global financial infrastructure. More than a decade later, enthusiasts continue to scrutinize every word he left behind. His warning about DoS attacks remains a relevant challenge for developers, underscoring that the work he started is never truly finished.
