It would be interesting to issue [NFT](https://en.wikipedia.org/wiki/Non-fungible_token)s for solution providers because the [NFT](https://en.wikipedia.org/wiki/Non-fungible_token)s represents the intelligence, skills and hard work.

Yes.

Submitted solutions are public to everyone. The compiled solutions are all fetchable but not their source code if their authors didn't published the source code.

Exactly same solutions can not be submmit twice because the hash of the compiled code is locked once submitted. Of course you can modify the solution a bit or just append some meaningless code to it and then submit it successfully.

Actually the winner of a competiton is lowest gas usage solution and if the gas usages are same, the earlest one will be chosen.
The winner of a competiton is the lowest gas usage solution and if the gas usages for two solutions are the same, the earlier one will be chosen.

Thus if other users plagiarize your solution, you are still earlier than them.

Submit an issue on [Problems](https://github.com/EulerDAO/problems) and provide the test case. Better to provide additional code in any language to prove your test case.
