Mysten Labs CTO Joins Anthropic to Focus on AI Security Research Sam Blackshear, co-founder and chief technology officer of Sui developer Mysten Labs, says he is stepping away from the company to join Anthropic, where he will work on defensive security research. In a post on...

This morning, I saw two departure announcements—coincidentally, both individuals are stepping down from their current roles but will continue in advisory capacities. First: Nikita Bier, Head of Product at X Platform, is stepping down as Head of Product for X and transitioning into an advisory role. Second: Sam Blackshear, co-founder and CTO of Mysten Labs, will leave Mysten Labs to join Anthropic, focusing on defensive security research. He will continue serving as an advisor to Mysten and the Sui ecosystem, and will also be involved in the upcoming Move Foundation. Everyone should thank Sam Blackshear for his vision, which helped make Sui the epic phenomenon it is today. No action is needed—just joining DC early qualifies you. Opportunities like this are rare—hopefully our paths cross again on the next project!

The person from SUI was so impressive that they were absorbed by Anthropic—let’s end this discussion here.

Sam is one of the smartest people I’ve met — a loss for Sui and Crypto, but an incredible hire by Anthropic.

Crypto once attracted nearly every top engineer wanting to build a new system. Now, that tide is beginning to shift toward AI. Sam Blackshear, co-founder of Mysten Labs and one of the minds behind Move, has just announced he’s joining Anthropic to work on AI security. Previously: + Blockchain was a new problem to solve. + Smart contract security was severely understaffed. + Layer 1s competed primarily on engineering talent. Today: + AI generates code faster than humans. + Attack capabilities are escalating in tandem. + Security has become a race between models themselves. What’s noteworthy isn’t just that a CTO is leaving a project— It’s where the world’s top engineers are choosing to spend their next few years. Narratives usually follow capital. But talent often leads both.

Move Creator Sam Blackshear Leaves Mysten Labs to Join Anthropic for Defensive Security Research Move creator and Mysten Labs co-founder Sam Blackshear has announced his departure from Mysten Labs to join Anthropic, where he will focus on defensive security research. He will remain an advisor to Mysten Labs and Sui ecosystem builders and stay involved with the planned Move Foundation. @EvanWeb3 will take over responsibility for setting Mysten Labs’ technical direction.

The founder of SUI is reportedly stepping down to join Anthro and will only serve as an advisor going forward.

Some of these former celsius Alex Mashinsky shills are prob the biggest risk to IOND and imho, the biggest reason why I want nothing to do with ionic moving forward. Anyone still supporting Mashinsky, in any manner, should be ignored, disregarded, and absolutely not trusted

This is a great example of the early defensive work that I'm sure will become very standard across the ecosystem and broadly. While AI does exponentially increase attack surfaces, it also exponentially empowers defenders.
