@EvanWeb3 My time at Mysten has been all of the adventure I could have hoped for or imagined. I’m incredibly grateful to the people of Mysten Labs and the Sui ecosystem—-thanks so much for everything. 29.8K views · 186 likes · 2 reposts · 10 replies Open on X →

@EvanWeb3 will step in to set the technical vision for Mysten. Evan personally recruited many of our strongest technical folks, and previously led technical teams at Apple and Meta. I’m excited to see the direction he will pursue. 23.2K views · 136 likes · 1 reposts · 3 replies Open on X →

I am passionate about the Move programming language, which I created and have worked on for the last 8+ years. There’s a Move Foundation in the works, and I'm eager to stay involved however I can. 35K views · 152 likes · 1 reposts · 3 replies Open on X →

Mysten Labs is the strongest peer group I've ever had the pleasure of working with. I'll remain a close advisor to Mysten and to any Sui ecosystem builders who reach out. 26.8K views · 160 likes · 2 reposts · 2 replies Open on X →

When I reflect on my career, I have been happiest doing hands-on technical work while exploring new problem domains. This is an opportunity to do both, and I’m motivated to work on security at a time when the balance of power between attackers and defenders is shifting. 27.9K views · 168 likes · 0 reposts · 5 replies Open on X →
