Constant Opcodes in BitcoinSV

Constant opcodes are fundamental building blocks in Bitcoin Script. They push predefined numeric values onto the stack, allowing for efficient and consistent value insertion in scripts.

Real-world Analogy

Think of constant opcodes like preset buttons on a microwave. Instead of entering "30 seconds" each time, you just press the "30 Sec" button. Similarly, instead of manually pushing common values onto the stack, you can use these opcodes for quick and standardized value insertion.

Did You Know?

  • OP_0 to OP_16 are among the most frequently used opcodes in Bitcoin scripts.
  • These opcodes are often used in multi-signature scripts and time-locking mechanisms.
  • OP_1 (also known as OP_TRUE) pushes the numeric value 1 onto the stack, not a boolean true.
  • OP_0 (also known as OP_FALSE) pushes the numeric value 0 onto the stack, not a boolean false.
  • Using constant opcodes instead of pushing raw numbers can make scripts more compact and efficient.
