 ### 1.2  Round randomness
 
-Randomness must be unpredictable yet verifiable. For round `r` the seed is:
-
 ```
-rand_r = BLS_sign(prev_block_hash, proposer_{r-1})
+newRandSeed = currentProposer.Sign(lastRandSeed) 
+randomness = hash(newRandSeed, currentRound)
 ```
-
-Because the identity of the previous proposer is only revealed at the end of round `r – 1`, no one can bias or predict `rand_r` ahead of time.
+* `newRandSeed` - VUF (Verifiable Unpredictable Function). It allows the generate seeds that are verifiable, unpredictable but not uniform.
