On closer inspection of your code, it looks like you are writing :
out << (quint16)(block.size<http://doc.qt.nokia.com/latest/qbytearray.html#size>()
- sizeof(quint16));

i.e size of your buffer as an quint16

yet while reading you're using quint64 :

if (tcpSocket->bytesAvailable() < (int)sizeof(quint64))
    return;
in >> blockSize;

thanks,
