There are many different blockchain projects out there, and the technology I am most interested in when it comes to digital marketing is Web 3.
It's all about decentralizing the global internet messaging system so that users have a lot more power over the content they are producing with their behavior.
This will drastically change marketing because the users themselves will be able to create and direct content as a group.
No one platform would control how they interact or what they produce.
They will always be in control of the content they put out there.
Better yet, they would be able to make money off their interactions with other users and the general community.
Several projects out there are poking around with this nebulous idea, but I haven't seen something that I would personally put a lot of money in.
I'm throwing a lot of money in small pools out there just to see which would gain traction.
But in terms of a specific project that fully embodies the full range of possibilities of the idea that I described above, there is none yet.
