Better progress reporting for aggregation
On the universal setup the aggregation phase can take several hours, so it would be good to have some nice progress reporting
do the contributors need to stay online for the aggregation? @emmorais perhaps you know?
I'm guessing maybe not, but if the aggregation fails for some reason (are we expecting it could fail or does verification catch all possible issues?) then their contribution will not be included despite our indication to them that it was successful. If we expect aggregation could fail, then they would need to stay online if they want to be sure that their contribution was successful.
They don`t need to be online for the aggregation algorithm to work. But it makes sense contributors would want to stay online for monitoring progress.
