In this episode, Anna Rose (https://x.com/annarrose) and Kobi Gurkan (http://x.com/kobigurk) chat with Arnaud Brousseau (http://x.com/arnaudbrousseau) and Jack Kearney (http://x.com/whojackjones) from Turnkey (http://x.com/turnkeyhq) about verifiable key management using trusted execution environments (TEEs). They share how their past work on custody and validators inspired them to build more sophisticated key management tools and some of the qualities TEEs enabled.
The discussion covers a range of challenges and techniques: the role of remote attestation and reproducible builds in ensuring trust, strategies to prevent downgrade attacks, and the use of authorization and policy layers to reduce misuse of keys while still enabling automation.
