Sora Suegami
Sora Suegami is a cryptography researcher and engineer. He began studying blockchain in 2018, and has since focused on researching and developing security technologies centered on cryptography. He co‑founded ZK Email—a project that uses zero‑knowledge proofs to verify contents in emails without revealing them in full—and led the development of several on‑chain protocols built on ZK Email, particularly for email account recovery. Additionally, he has been researching cryptographic theory. In 2025
Session
Indistinguishability obfuscation (iO) has been seen as the "holy grail" of cryptography, yet it remains far from practical due to the high complexity and inefficiency of existing constructions. In this talk, we will share the current status and challenges of our partial iO implementation and outline our roadmap toward practical iO. We will also show how iO could transform Ethereum into a global platform for privacy-preserving computation, opening the ecosystem to entirely new classes of users.
