As far as I know, gentildemon as work on this part but he tells me that we
don't need to store an array of random values synced up with the server. You
just need a initial seed, next value are provided using a very simple
function (in network/randomsync.cpp) :
...
/* RAND_MAX assumed to be 32767 */
static inline uint wormux_rand(void)
{
next = next * 1103515245 + 12345;
return((uint)(next/65536) % 32768);
}
...
So, you just need to send the initial seed, next value are available using
this function.
To keep everybody sync, you send the original seed and you don't have to send
a complete array.
