Martti Malmi, also known online as Sirius-m, played a crucial role in Bitcoin’s early development. His work and dedication helped shape the future of this revolutionary cryptocurrency. Here’s a look at why Martti Malmi is considered a Bitcoin legend.

Early Discovery and Mining

Born in 1988, Martti Malmi began programming at the age of 12. He studied computer science at the University of Helsinki and was influenced by the Pirate Party in Sweden, which focused on technological progress and freedom. This led him to reach out to Satoshi Nakamoto and offer his help with Bitcoin.

Martti discovered Bitcoin in May 2009

In May 2009, Martti Malmi discovered Bitcoin when it was still in its infancy and nearly worthless. At the time, he began mining Bitcoin and assisted Satoshi Nakamoto with code reviews.

Balancing his college studies, Martti spent his spare time working on Bitcoin, showing his early commitment to the project.

Defending Bitcoin

Martti made one of the first defenses of Bitcoin in an article for Anti-State.org. He argued that Bitcoin could separate money from state control and defended it against critics who questioned its value.

At that time, Martti was the only developer apart from Satoshi. In his free time, he contributed by adding bug fixes and features, and Satoshi personally thanked him for his work.

His early support was crucial in establishing Bitcoin’s credibility.

Working with Satoshi

Satoshi Nakamoto relied heavily on Martti for his writing. Martti compiled the first Bitcoin FAQ on forums and made strong arguments about Bitcoin’s potential value.

Even when Bitcoin was worth nothing, Martti saw its potential as a hedge against central banks and believed it was a smart investment.

Significant Sales and Advocacy

Privacy and Anonymity

Satoshi’s emails with Martti Malmi in May 2009 reveal Bitcoin’s intrinsic value. Satoshi explained that like gold, Bitcoin’s value comes from people valuing it, despite it being practically useless in the real world, making it perfect money.

Satoshi and Martti valued privacy, discussing ways to buy Bitcoin anonymously. They explored ideas like using Liberty Reserve, a digital currency platform that allowed anonymous transactions, highlighting their commitment to privacy in Bitcoin’s early days.

The Craig Wright Controversy

Although Martti is no longer directly involved in Bitcoin, he recently testified against Craig Wright, who claims to be Satoshi Nakamoto.

Martti’s testimony, which included his email correspondence with Satoshi, helped reveal inconsistencies in Wright’s claims.

Despite selling a large portion of his Bitcoins, he remains a strong supporter of the cryptocurrency and continues to work on projects related to decentralization.
