Confirmed 85 million premined:
// Block reward of the first (genesis) block
// This one is NOT used for premine to avoid sync issues and hardcoding the address
const uint64_t GENESIS_BLOCK_REWARD = UINT64_C(1); // not zero because that would cause a mess
// Block reward of second block (i.e. first actually mined block)
// Used for premine - but with a less hard-coded approach then baking it into the Genesis block
const uint64_t SECOND_BLOCK_REWARD = UINT64_C(85000000 * 100000000);
