These are some illustrative scripts to help those unfamiliar with Bitcoin scripts get started. Try copying these into your script editor and evaluating them in the Stack Evaluator.

Note: Whitespace does not matter. It's only in the following scripts for illustrative purposes.

Simple Addition

This script will push 02 and 05 onto the stack, then add them, resulting in 07.

0x02 0x05 OP_ADD

Stack Depth

This script will push '07' to the stack twice. Then it will push the number of stack items (2) to the stack.

0x07 OP_DUP OP_DEPTH

Greater than 5

This script will push 1 to the stack if the first item is greater than five. Otherwise, it will push 0. Change 0x02 to 0x06 and the result will change from 0 to 1.

0x02 0x05 OP_SUB 0x00 OP_GREATERTHAN

OP_IF
  0x01
OP_ELSE
  0x00
OP_ENDIF
