We all know that Satoshi Nakamoto is the founder of Bitcoin. This ID first appeared in the mailing list of the "Cypherpunk" forum with just a few lines of information: Satoshi Nakamoto, born on April 5, 1975, Japanese, male. It wasn’t until 2008, when Satoshi Nakamoto published the Bitcoin whitepaper, that this ID gained widespread attention among cypherpunks.

After creating the Bitcoin system, Satoshi Nakamoto spent a long time on the Bitcointalk forum, discussing Bitcoin’s technical updates and development direction with fellow tech enthusiasts. However, one incident shattered the peace of the Bitcoin world and prompted Satoshi Nakamoto’s disappearance—the famous "WikiLeaks" incident.

The incident occurred in December 2010. At the time, there was a non-profit media organization called "WikiLeaks," whose mission was to expose corporate and government secrets through insiders, thereby ensuring their operations were completely transparent. While the organization’s original intention was noble, reality often fell short of expectations.

On December 5, 2010, WikiLeaks angered the U.S. government by leaking diplomatic cables. The U.S. government shut down all its traditional financial donation channels, such as credit cards and bank transfers. Faced with the loss of funding, WikiLeaks founder Julian Assange, also a cypherpunk, announced that Bitcoin would be used as the donation channel.

This was Bitcoin’s largest payment transaction since its inception, and the Bitcoin community was ecstatic. However, Satoshi Nakamoto strongly opposed this move. In his view, the Bitcoin system was still in its developmental stage, and attracting the attention of a powerful government like the U.S. so early was unwise. He even stated on the Bitcointalk forum: "It would have been nice to get this attention in any other context. WikiLeaks has kicked the hornet’s nest, and the swarm is headed towards us."

Out of security concerns, on December 12, 2010, without any farewell, Satoshi Nakamoto answered a question about the Bitcoin 0.3.19 version’s remediation plan on Bitcointalk and never appeared on the forum again. However, at this point, Satoshi Nakamoto had not completely left the Bitcoin world. He handed over the management of Bitcoin’s code to Gavin Andresen and maintained contact with him for a while, hoping to further decentralize development authority.

On April 26, 2011, Gavin Andresen received Satoshi Nakamoto’s last email to him. At the time, Satoshi Nakamoto learned that Gavin had been invited to an event organized by a CIA-affiliated group. He expressed that he did not want his image to be further mythologized. Instead, Gavin should focus more on discussing Bitcoin as an open-source project to build greater trust among developers.

But this was still not Satoshi Nakamoto’s final email. In March 2014, the media mistakenly identified a computer engineer named Dorian Satoshi Nakamoto as the real Satoshi Nakamoto. The poor Dorian was then subjected to global scrutiny and harassment. At this point, Satoshi Nakamoto sent his last email, stating: "I am not Dorian." This letter saved Dorian.

Later, a few more emails were sent from Satoshi Nakamoto’s address, but their content was threatening, demanding money. It was inferred that his email had been hacked. Since then, all traces of Satoshi Nakamoto have been lost, and he has become a complete mystery.

To this day, the reasons for Satoshi Nakamoto’s disappearance remain speculative. Some say it was because Bitcoin was ready to move forward without its founder, while others believe Satoshi Nakamoto wanted to avoid drawing unwanted attention. Regardless of the reason, Satoshi Nakamoto fulfilled the mission of his era—bringing Bitcoin and blockchain to the world. And they will continue to create waves of change in the future.
