There's for example a project called PoolTogether that uses VRF. It basically runs a lottery.
I'd like to know if the following suggestion is expected and feasible to integrate in contracts:
In this way, no user has the ability to manipulate the seed and have all incentive to give a random number. At the same time, they can ensure it's probably fair because they provided a seed.
Does this make sense? Any obvious vulnerability or problem?
