Trail of Bits

Recent research has revealed that physical attacks on Intel SGX and AMD SEV-SNP are possible when a party is able to attach an interposer to DDR4 RAM. These findings have raised important questions about the practical limits of trusted execution environments (TEEs) as the foundation for secure, privacy-preserving computation.

While hardware vendors have confirmed that these vulnerabilities will not be patched, the implications extend beyond any single exploit. They highlight the need to rethink *where* trust is placed — and how layered designs can continue to provide strong privacy guarantees, even in imperfect environments.

Join **Tjaden Hess**, Principal Security Engineer at **Trail of Bits **and **Andy Campbell**, Head of Product at **Applied Blockchain / Silent Data**, as they unpack what these discoveries mean for teams building on TEEs today.

Together, they'll explore how projects can adapt through secure architectures, layered privacy models, and resilient attestation approaches — keeping confidentiality and trust at the core of next-generation blockchain infrastructure.
