Often there are situations in which a chain of blocks with a later timestamp but with greater trust replaces the earlier found blocks.
I do not like such situations, and I consider this vulnerability. In the updated code, a chain of blocks with a larger time stamp loses its trust.
Code ...
Code:
CBlockIndex* pblockindex = NULL;
    int nPossibleHeight = pindexNew->pprev->nHeight + 1;
    if (fDebug)
        printf(" 'AddToBlockIndex()' - The new block pretends to a height %d, block chain height %d\n", nPossibleHeight,
               pindexBest->nHeight);

    if (nPossibleHeight < pindexBest->nHeight && fHardForkOne)
    {
        if (nPossibleHeight <= pindexBest->nHeight - nTriggerDepth)
        {
            if (fDebug)
                printf(" 'AddToBlockIndex()' - The new block pretends to a height %d, maximum allowed block height for a competing chain %d\n", nPossibleHeight,
                pindexBest->nHeight - nTriggerDepth);
            pindexNew->bnChainTrust = 0;

        }

        pblockindex = FindBlockByHeight(nPossibleHeight);
        if (pindexNew->GetBlockTime() > pblockindex->GetBlockTime())
        {
            if (fDebug)
                printf(" 'AddToBlockIndex()' - Generation time of a new block date=%s later than available in the database date=%s\n",
                DateTimeStrFormat("%x %H:%M:%S", pindexNew->GetBlockTime()).c_str(), DateTimeStrFormat("%x %H:%M:%S",
                pblockindex->GetBlockTime()).c_str());
            pindexNew->bnChainTrust = 0;
        }
        else if (pindexNew->GetBlockTime() < pblockindex->GetBlockTime())
        {
                 if (nPossibleHeight < pindexBest->nHeight && nPossibleHeight > pindexBest->nHeight - nTriggerDepth)
                 {
                     if (fDebug)
                         printf(" 'AddToBlockIndex()' - The generation time of a new block date=%s earlier than the one in the database date=%s\n",
                         DateTimeStrFormat("%x %H:%M:%S", pindexNew->GetBlockTime()).c_str(), DateTimeStrFormat("%x %H:%M:%S",
                         pblockindex->GetBlockTime()).c_str());
                     bnBestChainTrust = pblockindex->pprev->bnChainTrust;
                 }
        }
    }

2) If the "ChainTrust" matches, the network will not wait for the child block from the competitor’s node. Code..

Code:
// New best
    if (pindexNew->bnChainTrust > bnBestChainTrust)
    {
        if (!SetBestChain(state, txdb, pindexNew))
            return false;
    }
    else if (pindexNew->bnChainTrust == bnBestChainTrust && fHardForkOne && pindexPrevPos->GetBlockHash() >=
        pindexPrevPrevPos->GetBlockHash())
    {
        printf(" 'CBlock' - BestChainTrust %s\n", bnBestChainTrust.ToString().c_str());
        printf(" 'CBlock' - NewChainTrust %s\n", pindexNew->bnChainTrust.ToString().c_str());
        if (((pindexNew->IsProofOfStake() && pindexBest->IsProofOfStake()) ? (pindexNew->GetBlockHash() >
            pindexBest->GetBlockHash()) : (hash > pindexBest->GetBlockHash())) ||
            (pindexBest->IsProofOfWork() && pindexNew->IsProofOfStake()))
        {
            printf(" 'CBlock' bnChainTrust = bnBestChainTrust - Block accepted\n");
            if (!SetBestChain(state, txdb, pindexNew))
            {
                return false;
            }
        }
        else
        {
             printf(" 'CBlock' bnChainTrust = bnBestChainTrust - Block not accepted\n");
             return false;
        }
    }
    else if (pindexNew->bnChainTrust == bnBestChainTrust && fHardForkOne && pindexPrevPos->GetBlockHash() <
             pindexPrevPrevPos->GetBlockHash())
    {
        printf(" 'CBlock_' - BestChainTrust %s\n", bnBestChainTrust.ToString().c_str());
        printf(" 'CBlock_' - NewChainTrust %s\n", pindexNew->bnChainTrust.ToString().c_str());
        if (((pindexNew->IsProofOfStake() && pindexBest->IsProofOfStake()) ? (pindexNew->GetBlockHash() <
            pindexBest->GetBlockHash()) : (hash < pindexBest->GetBlockHash())) ||
            (pindexBest->IsProofOfWork() && pindexNew->IsProofOfStake()))
        {

             return false;

    }
    txdb.Close();

  To enable the function "setcontrolrealtime", you must specify the parameter "setcontrolrealtime=1".
This function changes the limit on the number of transmitted blocks. In the case when the sent "inv"
has one size, and the received "getdata" the other limit is set to 10. Additionally, when transferring
blocks with a height of more than 150000, the limit is set to 30.
  Starting from the previous version, in the event of a socket error, the transfer of a chain of blocks is
interrupted on the block with an error.

 These additions are implemented to eliminate the possibility of repeated use of the same coins. This is exactly what happened on the Cryptopia Exchange. For double spending, coins with a small number of connections and a small network hash rate or POS coins were chosen. Moreover, an attack of 51% is not obligatory, it is enough to tear off the exchange's wallet from its main network. Coins with which this focus was repeated many times and were delist from the Cryptopia.

 New settings and what they are for.

 Options - ("setreload" "setreconnecting") - used when synchronizing blocks.

1) default
Synchronization mode with disconnection from peers sending incorrect data.

setreload=0
setreconnecting=1

2)
Use in cases where some members of the network are not interested in the presence of a large number of synchronized nodes and if they interfere with the completion of synchronization.
Synchronization mode with ignoring all transactions with the current(real) time stamp and disconnection from peers who send incorrect data.

setreload=1
setreconnecting=0


 The "setreconnectpresenttime" option is used after synchronization is complete. Reconnects the wallet to another peer in the absence of a new block within the specified time.
The option "timeupreconnectpresenttime" sets the time in seconds.

Used in many cases, for example, to counter the module "TARPIT".

1) default

setreconnectpresenttime=1
timeupreconnectpresenttime=60*20

 The inclusion of many features was tied to the "debug" setting and was not written about this. In this version, this dependency is removed.
Synchronization of blocks is implemented in three modes -

1)
setreload=0
setreconnecting=0
2)
setreload=0
setreconnecting=1
3)
setreload=1
setreconnecting=0

Coinexchange.io installed the latest version of the wallet and synchronized the blockchain from the zero block to check the balance.

Thank you for your dedication to this project Deff. Without you this coin would have died many moons ago. Cheers!
