# Randomness in Dione network
|
||
|
||
“One thing that traditional computer systems aren’t good at is coin flipping,” says Steve Ward, Professor of Computer Science and Engineering at MIT’s Computer Science and Artificial Intelligence Laboratory.
|
||
|
||
Computers act deterministically and most of the time calculates a preudo-random numbers.
|
||
|
||
In Dione network randomness used to calculate the winner of the consensus round on particular epoch. Using pseudo-random values for such operation could break the consensus behaviour and malicious node could predict the next round winners by flipping the numbers over and over.
|
||
|
||
Since we can't trust preudo-random numbers generated by the node itself we have to find a way to get as random value as possible.
|
||
|
||
Dione network uses Drand (dee-rand) - distributed randomness beacon.
