It would be even better if cryptocurrency community didn't hijack the term cryptography (which even overlaps theirs).

You mean "hijack the term crypto" right? I think cryptography still means the same thing in the cryptocurrency community.

Yes, merci, point taken.

Too late.

The front page says "...test their passion for cryptography. Each task will be based on a particular cryptographic primitive or it will include a direct application of cryptography in other fields."

Not sure why you're downvoted. I read it the title and immediately thought there was a blockchain involved.

Downvotes are probably stemming from general hatred of cryptocurrencies. After all they “stole” the word crypto in mainstream media, just like criminals “stole” the word hacker long time ago.
