Vitalik Introduces New Cryptographic Obfuscation Technology Diamond iO, Capable of Hiding Program Logic and Keys
Ethereum co-founder Vitalik Buterin published an article introducing a new cryptographic obfuscation technology called Diamond iO.
This technology enhances computational efficiency from cosmic to planetary levels through more aggressive assumptions, built on attribute encryption and fully homomorphic encryption, capable of hiding program logic and keys.
Currently in the early research stage, it relies on new assumptions and faces overhead challenges, with the potential to advance the development of practical program obfuscation.

Vitalik Buterin has long focused on the forefront of cryptography and previously published a lengthy article outlining the indistinguishability obfuscation (iO) technology tree. Diamond iO, as a key follow-up in the series, was proposed by researchers and achieved efficiency breakthroughs through modifications to the BGG+14 attribute encryption scheme.
The capital and resource pathways are reflected in the Ethereum Foundation and related cryptographic research's continuous investment in privacy infrastructure, aiming to transition iO from theory to a stage that supports blockchain and AI privacy applications, motivated by the goal of constructing trustless third-party computing primitives.
This is analogous to the early evolution of SNARKs from theory to practicality since 2010, and the commercialization process of fully homomorphic encryption, currently in a critical transition from galaxy-level infeasibility to planetary-level near feasibility.
Essentially, this represents a technological substitution: Diamond iO exchanges stronger assumptions for efficiency leaps, potentially replacing traditional multi-layered iO constructions and redefining the feasibility boundaries of privacy computing.
