Ads.txt is a fraud prevention file that helps ensure that only authorized people are representing your ad inventory. The entire ad industry is adopting this new measure, and we need to get this file set up on your site ASAP in order to prevent any potential revenue impact.
This file will need to be updated periodically. You will be able to tell if it is out of date by checking your dashboard and looking at your Ads.txt site health.
Blogger has implemented a solution that makes this super easy to install and setup. Here are the directions, customized for Mediavine ads, below:

3. On the left, click Settings.
4. Under "Settings," click Search preferences.
5. Under "Monetization," find "Custom ads.txt" and click Edit.
6. Click Yes.
7. Open your Ads.txt file by navigating to your Mediavine Dashboard Settings page, in the Ad Setup Tab.
8. Click the Download Ads.txt button, open it in a text editor, select the entire contents, and copy them.
9. Paste the text into the box in Blogger.
10. Click Save settings.
11. Optional: To check the content of your ads.txt file, go to http://yoursite.com/ads.txt
