You’ve experienced this: You‘ve bought something (or just searched for it) and now you have ads for that or a similar item following you around. What’s happening is you have two services – the shop you bought from and the ad delivery network – that are talking to you but not each other, and that leads to a not so great user experience.
A similar thing happens for subscriptions and memberships. A concrete example: I listen to The Daily, a NYTimes podcast, every day on Spotify. Annoyingly I have to listen to quite a lengthy segment that’s trying to convince me to subscribe to the Times – even though I’m a subscriber already.
I can see a future where Spotify will check my ethereum wallet, see that I have the New York Times membership token and give me The Daily version for members without promotions. Maybe they will even create a version without ads and special content for long time or higher tier subscribers.
In that future I could take advantage of many other benefits and services based on my existing purchases and memberships. Event discounts for NYTimes or Spotify members? I just need to sign a message from my wallet that checks that my membership is valid without having to sign up or share any additional information. Bought the audio book on Amazon and the publisher offers the ebook for free on their site? Easy to verify your purchase, no need to login or share your Amazon data. You’re a New York WeWork member and are in Berlin? They can easily verify your membership and give you free or discounted access without having to look you up in their system. The blockchain let’s different services talk to each other, cross checking your memberships and purchases with minimal data sharing, if you allow it. Your purchase and membership tokens function as universal keys.
