Vitalik Buterin calls obfuscation cryptography's hardest unsolved problem and explains why cracking it changes everything.

Vitalik Buterin said obfuscation is cryptography’s “final boss,” citing impractical iO schemes with “literally galactic” runtimes.

The Ethereum co-founder says indistinguishability obfuscation could one day act like a “trustless trusted third party,” but today’s versions remain far too slow for real use.
