Program Obfuscation

Definition ∞ Program obfuscation is a technique used to transform a computer program into an equivalent but unintelligible form, making it extremely difficult for reverse engineers or attackers to understand its logic. While the program retains its original functionality, its internal workings are obscured. In cryptography, this can be used to protect proprietary algorithms or sensitive data within smart contracts.
Context ∞ In the context of blockchain and smart contract security, program obfuscation is a subject of academic research with potential applications for protecting intellectual property and enhancing privacy on public ledgers. The current challenge lies in developing robust and provably secure obfuscation schemes that do not significantly impact performance or introduce new vulnerabilities. Practical applications are still in early stages.
