Google has announced that later this year it will require everyone using its publisher products (Google AdSense, Ad Manager or AdMob) to use a Google-certified CMP that integrates with the TCF when serving ads to users in the European Economic Area or the UK.
If you have Adsense ads on your blog and you don't know what a CMP or TCF is, you are probably doing something wrong and you will have to adapt in order to continue displaying ads. Both are explained in this post.
Now, Google is supposed to send us a list of certified CMPs that have been integrated with the IAB Europe TCF and that comply with the TCF specifications and you will have to use one of the ones on that list.
Although this list is unknown at the moment, it is very likely to be the same list that IAB Europe publishes and updates regularly and that you can consult in the TCF v2.2 CMP Service tab on this page.
This means that you will have to say goodbye to any of those cookie-trap posters or plugins that do not comply with the GDPR and also that Google has definitively abandoned the idea of that replacement it called FLoC (Federated Learning of Cohorts).
As we don't know much more about their second proposal,"Topics" (cookie-free ads), it leads us to believe that we still have a few more years of dealing with cookie consent management banners as we know them today.
If you are looking for a compliant CMP, I still recommend Complianz. It's the one I've been using for three years now. Its free free version version is functional, although to ensure compliance, it has three paid versions which offer interesting and necessary functions such as legal documents and other interesting settings at a much more reasonable price compared to the other existing paid options.
