• Bitcoin, Early developer. "An amateur college developer in 2009, Malmi played a crucial role in bitcoin's early days as the only active developer working alongside Satoshi – and even striking up a bit of a friendship. He earned Satoshi's trust enough to be given admin access to the website Bitcoin.org, and most of the changes in bitcoin's second code release are attributed to him.

But a couple years in, Malmi followed Satoshi's lead and left the project, thinking bitcoin didn't really need him anymore.

"I felt like bitcoin had already gone from zero to one, so to say. It was already up and running with a growing community and had lots of great developers working on it," he told CoinDesk."

• Bitcointalk.org, original founder
• Identifi, founder
• MONI, co-founder
• Stellar, wants to advance it through MONI
• Joined a team of developers launching a new cryptocurrency called AXE. The project, which is combining Malmi's Identifi online reputation system with decentralized database system GUN, is taking on the long-desired mission of decentralizing the Web.
