I proposed a block hash lottery on github, where few would win a lot. I think this would take advantage of the true potential of XCP escrow.

I believe this can be a killer app for CP.
If N players can escrow funds in the same pot, and N is a large number, and one player wins the entire jackpot - then CP offers a very good lottery. 100% is paid back to the players (i.e. all to the winner) and the game is 100% transparent.
Happy to use it. Works as described:)
