Bitcoin Script

Bitcoin Script is a simple, stack-based programming language used to define spending conditions for Bitcoin transactions. It operates on the Bitcoin blockchain to specify how bitcoins can be spent, such as requiring a digital signature or a time lock. As a non-Turing complete language, it prioritizes security and predictability over complex functionality.

Also known as: Bitcoin Scripting Language, Bitcoin Transaction Script, Script, Bitcoin Opcodes, BTC Script
