Vitalik Buterin Explores 'Local Mixing': A Radical New Path to Code Obfuscation

Code Obfuscation via Local Mixing

In the third part of his series on cryptographic obfuscation, Vitalik Buterin dives into 'local mixing', a radically different approach that borrows ideas from symmetric cryptography rather than relying on traditional math like elliptic curves or lattices. The method transforms circuits into reversible forms, hardens them against reverse-engineering, and then shuffles gates to hide logic. Buterin acknowledges the high risk, noting past failures in white-box cryptography, but suggests that AI could accelerate progress, potentially stabilizing the technique within years instead of decades.
