you should also lock when checking for the length. Consider using RWMutex instead of Mutex

It is good to have this check to detect bug, but you also need to check that committeeSize <= len(mock.clients)

Fixed.

No reason to panic, print a fat error message and return 0

Changed

data := binary.LittleEndian.Uint32(proof)
// calculate thresholds
threshLeader := mock.calcThreshold(3) // expect 3 leaders
threshActive := mock.calcThreshold(mock.comitySize) // expect comitySize-3 actives

don't understand the comment, why -3?


if data < 10 {
// calculate hash of proof
hash := fnv.New32()

you should have a struct responsible for hashing, this struct should also return the max value (instead of the maxUint32 above). This way you'll make sure that no one changes the hash type without forgetting to update the max value
