Mysten CTO Joins Anthropic for AI Security Push

Sam Blackshear, co-founder and CTO of Mysten Labs, is leaving the company to join Anthropic and focus on defensive security research. The departure comes as AI increasingly identifies software vulnerabilities, automates phishing campaigns, and accelerates attacks on blockchain infrastructure.

Mysten Labs' Sui blockchain was founded by Blackshear and four former Meta executives in September 2021. After his departure, Evan Cheng, Mysten's co-founder and CEO, will take over the 'technical vision' for the company.

Blackshear expressed enthusiasm about working on security during a time when power dynamics between attackers and defenders are shifting. He plans to remain involved with Mysten as an advisor and continue participating in the Move Foundation.
