How do I get a random value in FunC?

Is there any way to get random value in Func? I'm looking for a VRF, though other solutions are appreciated too.

Unfortunately I'm not familiar with any Oracle solutions that provide VRFs. Here is a way to get a random number, but it can still be manipulated by validators:

int seed = cell_hash(begin_cell()
    .store_uint(now(), 256)
    .store_uint(block_lt(), 256)
    .store_uint(cur_lt(), 256)
.end_cell());
randomize(seed);

Randomize can be put in more complex schemes to significantly decrease the probability that a validator will affect the random value, but there isn't anything flawless. Here's a link to more information:
