Ok, as promised here is the full blockchain I got from my Linux wallet as a backup about a week ago:
https://mega.nz/#!ygViUI4b!YorYjEl2BKZj6u5m6AcSCQkQSGKqbBshY1VOfCtWerMI make backups periodically, as this chain tends to fork due to small number of active clients.
It is 1.23GB. I believe it is the correct chain, as it seems to be moving well. But as far as I understand, there is not much means to check it.
EDIT: ok, I can confirm now this is the correct blockchain. I have made test deposits to Bittrex and Cryptopia, and both went ok, so this is the same chain exchanges are running on.
