The Ethereum co-founder outlined a new program obfuscation approach after earlier conservative designs were viewed as so impractical they would take longer than the lifetime of the universe to run.
Vitalik Buterin published a technical article describing Diamond iO, a new program obfuscation protocol. He framed it as a potential step toward making a long-impractical area of cryptography more plausible, contrasting it with earlier conservative obfuscation designs that were considered unusable because running them would take longer than the lifetime of the universe. Program obfuscation aims to make software hard to reverse engineer while preserving its functionality, a goal that has historically been difficult to achieve in practice.
