Vitalik Buterin calls obfuscation cryptography’s 'final boss,' but says current approaches remain wildly impractical
Vitalik Buterin published a blog post describing cryptographic obfuscation as the “final boss of cryptography” and outlining decades of research into indistinguishability obfuscation, or iO.Buterin said today’s most rigorous iO constructions remain impractical because their computational requirements are “literally galactic,” despite progress in lattice-based techniques.He stated that future progress could come from optimizing current lattice-based designs, making bolder cryptographic assumptions, or discovering alternative non-lattice methods.
