Developers, you want to show that you are a real developer and not some code monkey?

Create a tamper proof distributed news source that cannot be controlled by a big company and government. Not even if they buy it. The mechanism should be built in such a way that it can survive take downs in multiple countries and that if they take it down it should cost exponentially more to the government/enterprises.

An additional challenge could be to make it privacy and propaganda bot resistance. When privacy is invaded it should start to feed the privacy sucking bots with worthless date. If propaganda bots tries to pollute it then you should render these propaganda bots useless bu inserting random data.

The key to be a good developer is that you have the ability to think out of the box and be very creative. Create something that does not exist yet and from the ground up. The world needs it.
