This might be an error within BlockExperts explorer.
I verified the blockchain as shown BlockExperts against the official TTC client. There is no error. If you don't believe BlockExperts, open up the TTC client, and manually examine the coinbase transactions for the suspicious blocks (e.g. 1779, 1819, 1949, 2372, 66574, and 66696). None of these blocks have the typical 8008 + fee reward --- they are much higher.
There was a premine here...
The premining only occurs at block 2, as indicated in the source code:
https://github.com/tittiecoin/tittiecoin/blob/master/src/main.cpp#L830-L841Such sporadic increases in block reward, as shown above, are highly suspicious. Please forward this issue to the development team. Thanks!
