Blockchain competition

[Ouss95]

Hello Blockchain Comunity,

I would like to know if there is an international Blockchain competition or Olympiad.
If there is one please reffer me to it because I goole it and I didn't find something good.
If there isn't why blockchain community doesn't support one to encourage its community,
for example why we don't have something like Kaggle  in blockchain.
For people who doesn't know kaggle, it's an international plateform where there is competition of machine learning
and deep learning every days.

thanks
