Bitcoin Script Security

Script

Bitcoin Script, a stack-based programming language embedded within the Bitcoin protocol, governs the conditions under which bitcoins can be spent. It enables the creation of complex transaction logic beyond simple payment-to-address scenarios, facilitating features like multi-signature wallets and timelocks. Understanding its operational semantics is crucial for assessing the security implications of smart contracts built upon it, particularly concerning potential vulnerabilities arising from improper script design. The inherent limitations of Script, however, restrict its complexity compared to more general-purpose programming languages.
