I may be misunderstanding this, but is there a problem with the way that the JKC code generates random super blocks, which makes it possible to predict when all of the super blocks will occur in the future? The random number generator in main.cpp (below) generates a deterministic random number based on a particular seed value.

    int static generateMTRandom(int s, int range)
    {
        random::mt19937 gen(s);
        random::uniform_int_distribution<> dist(1, range);
        return dist(gen);
    }

This is called later when determining the block rewards (below), but using the block height as the seed value. By using a seed value like the block height that can be known for each block in advance isn't it possible to predict which blocks will be super blocks and what their value will be?

    int rand = generateMTRandom(nHeight, 100000);
   / printf("===>> nHeight = %d, Rand = %d\n", nHeight, rand);

    if(rand > 99990)
    {
    nSubsidy = 1000 * COIN;
    }
    else if (rand < 1001)
    {
    nSubsidy *= 3;
    }

Apologies if I've got this wrong (or if it is well known), I'm not a good c++ programmer, but a bit of quick and dirty test code seems to suggest that this might be the case. If this is right, is it worth an update that changes the seed value to something like the previous block's hash?

Ah, I thought so. It was a comparison of the JKC and LKY code that made me think more carefully about this in the first place. Does this call for a fork? I guess there's no guarantee that you will mine a particular block (rather than a competitor) even if you know its value, but it would be good to get it working right.

All payouts (save 1, waiting for a payout address) have been made from the JKC pool on CryptoCoin Mine.

The problem that I was having on the DGC pool did not seem to effect the JKC pool. However, I have found a newer and much more efficient mmcFE code base that I will be using for the pools.

The new code base uses a different database structure, so registering will be necessary when the pool comes back online.

Thank You

Back on the road

I see sudden rise of JKC network hash rate today

My mine computer crash 2week ago :/ Anyone know can i force restart with teamviewer that? I know computer have power on, but that is only in "tilt" mode or something what that make sometimes when mining.

Need i install some new wallet?

THE JKC CRYPTOCOIN POOL IS TESTING.
Registration is open, however the testing mining port is not public.
This allows the JKC community to watch the test.
I will open the public mining ports when the pool is ready.
