Function opcodeEqual

txscript/opcode.go:1397–1409

opcodeEqual removes the top 2 items of the data stack, compares them as raw bytes, and pushes the result, encoded as a boolean, back to the stack. Stack transformation: [... x1 x2] -> [... bool]

(op *opcode, data []byte, vm *Engine)

//
// Stack transformation: [... x1 x2] -> [... bool]
func opcodeEqual(op *opcode, data []byte, vm *Engine) error {
	a, err := vm.dstack.PopByteArray()
	if err != nil {
		return err
	}
	b, err := vm.dstack.PopByteArray()
	if err != nil {
		return err
	}

	vm.dstack.PushBool(bytes.Equal(a, b))
	return nil
}

// opcodeEqualVerify is a combination of opcodeEqual and opcodeVerify.
// Specifically, it removes the top 2 items of the data stack, compares them,
