Great idea! I like it, but first I have to Google all those terms.

If I had a trusted third party, the whole commitment scheme would be completely pointless.

This method is not good for my application (commitment schemes). If alice wants to get a collision, she could simply create an output by herself without having throwing a coin.

@e501 Good idea. Getting a lot of digits of $\rm e$ is not too difficult... But is it really safe of collisions?

Another thing would be squaring modulo somthing - solving this is NP-hard, but i doubt that it is impossible to find collisions.

I have an idea by myself: Could one use exponentiation modulo something as a hash function?
