Mysten Labs co-founder Sam Blackshear said he is joining Anthropic to work on AI security. He framed the move around AI’s growing impact on the balance between attackers and defenders.
The development matters because Blackshear linked the move to a broader security concern: AI is changing the balance between attackers and defenders. For crypto readers, that framing is notable because security is central to blockchain networks, digital asset platforms and the software systems around them.
Mysten Labs co-founder Sam Blackshear said he is joining Anthropic to work on AI security, according to Cointelegraph. The move takes a senior technical figure from the crypto infrastructure world into one of the companies focused on artificial intelligence.

Mysten Labs is known in the crypto sector, and Blackshear’s role as co-founder and technology chief made him a visible technical leader. His shift to Anthropic highlights how expertise from blockchain engineering can overlap with emerging AI security work.
The source did not provide additional details on Blackshear’s exact role, start date or specific projects at Anthropic. It also did not indicate any immediate operational change at Mysten Labs tied to the move.
For now, the key takeaway is the direction of travel: a senior crypto technologist is moving into AI security at a time when the industry is increasingly focused on how AI may affect defensive systems, software reliability and attacker capabilities.
