À PROPOS DE CET ÉPISODE
This week, Anna speaks with Sergey Gorbunov, Engineer at Circle, about Arc, Circle’s new EVM-compatible Layer 1 blockchain, and its approach to a TEE based on-chain privacy. They begin by revisiting Sergey’s journey from Axelar to Circle, reflecting on the evolution of cross-chain infrastructure, the aftermath of the Terra collapse, and how Circle’s acquisition of Interop Labs led to the development of Arc.
The conversation then turns to Arc’s architecture, including its privacy layer, known as the Privacy Sector, and the decision to build it around Trusted Execution Environments (TEEs) rather than ZKPs or FHE. Sergey explains the design trade-offs, discussing privacy, composability, enterprise infrastructure, and why he believes TEEs are currently the most practical foundation for programmable private execution.
