github source has not been updated ...

version 1.1 released. Download links updated in OP. After block 750, it will revert back to ppcoin's diff retarget algorithm (still adjust each block). Hopefully this will fix the diff oscillation issue.

   if(pindexLast->nHeight < 750)
   {
      int blockstogoback = nTargetInterval;

      const CBlockIndex* pindexFirst = pindexLast;
      for (int i = 0; pindexFirst && i < blockstogoback; i++)
         pindexFirst = pindexFirst->pprev;
      assert(pindexFirst);

      // Limit adjustment step, this should be enough since it is continuous adjustment, max twice or half
      int64 nActualTimespan = pindexLast->GetBlockTime() - pindexFirst->GetBlockTime();
      printf("  nActualTimespan = %"PRI64d"  before bounds\n", nActualTimespan);

      if (nActualTimespan < nTargetTimespan/2)
         nActualTimespan = nTargetTimespan/2;
      if (nActualTimespan > nTargetTimespan*2)
         nActualTimespan = nTargetTimespan*2;

      // Retarget
      bnNew.SetCompact(pindexLast->nBits);
      bnNew *= nActualTimespan;
      bnNew /= nTargetTimespan;

      /// debug print
      // printf("GetNextWorkRequired RETARGET\n");
      printf("nHeight = %d, nTargetTimespan = %"PRI64d", nActualTimespan = %"PRI64d"\n", pindexLast->nHeight, nTargetTimespan, nActualTimespan);
      // printf("Before: %08x  %s\n", pindexLast->nBits, CBigNum().SetCompact(pindexLast->nBits).getuint256().ToString().c_str());
      // printf("After:  %08x  %s\n", bnNew.GetCompact(), bnNew.getuint256().ToString().c_str());
   }
   else   // ppcoin algo
   {
      const CBlockIndex* pindexPrev = GetLastBlockIndex(pindexLast, fProofOfStake);
      const CBlockIndex* pindexPrevPrev = GetLastBlockIndex(pindexPrev->pprev, fProofOfStake);
      int64 nActualSpacing = pindexPrev->GetBlockTime() - pindexPrevPrev->GetBlockTime();

      bnNew.SetCompact(pindexPrev->nBits);
      int64 nTargetSpacing0 = fProofOfStake? nTargetSpacing : min(nTargetSpacingWorkMax, (int64) nTargetSpacing * (1 + pindexLast->nHeight - pindexPrev->nHeight));
      int64 nInterval = nTargetTimespan / nTargetSpacing0;
      bnNew *= ((nInterval - 1) * nTargetSpacing0 + nActualSpacing + nActualSpacing);
      bnNew /= ((nInterval + 1) * nTargetSpacing0);
   }

Sorry guys, this looks like a failed trial.

I think we have two options:

1. Hard-fork at say, block 800. I can revert back to PP-coin/Novacoin retarget algorithm (still each block).
2. Do nothing and let it die. In which case I'll lock this thread.

Let me know which you prefer.

I have gotten like 2 total so far. I'm just saying, from all the last coins that restarted, you may as well just not start it again and let it die

possible ... but could also just be a saying from someone owning some blocks already ^^

For the retarget, a weighted average would probably be better than the current one ...

Also for the pre-launch test, the oscillation should have been visible anyway ... Values would not have been that high, but relative amplitude must have been identical.

If you restart it, the coin is dead

$ ./galaxycoind.exe getmininginfo
{
    "blocks" : 612,
    "currentblocksize" : 1000,
    "currentblocktx" : 0,
    "difficulty" : 1.51249740,
    "networkhashps" : 187208267,
    "errors" : "",
    "pooledtx" : 0,
    "stakepower" : 0,
    "testnet" : false
}

now is better. But looks like re-target based on the last 10 blocks still cause some oscillations... may need to average more to smooth out.
