Again: Does anyone know if it is possible to delete the downloaded blockchain, re-trigger downloading it from start without lossing account date or blackbytes? Please tell me, I'm having heavy problems with the client.
I believe the Byteballs are stored in the DAG, so don't delete it.
Can you try this so that you don't lose anything:
Back up the entire user folder where all of the Byteball files are kept including the DAG,(should be over 1 gig)
Ensure it's all backed up / moved.
Now you can safely delete the files and restart, see what happens.
If you Blackbytes don't return then you have neutral news and bad news.
Bad news is that you're going to have to reload your backup.
Neutral news is that you have not lost anything.
I already did something like that. Also to use light wallet with my original Account. But Blackbytes were gone. As far as I could get information, I believe the blackbytes were send only once to a target address and inserted into the chain (somehow) privately only. The public part of blockchain does not see them.
I'm little disappointed that so less information is available in any FAQ page about those in deep questions, such as:
* Use case of Blackbytes; How to handle them properly; how they act inside the wallet,...
* Is there nothing like "blockheight" to be displayed as statistic how many blockchain parts are still left to download
* In regular intervals, the Wallet sends some Megabytes to a Byteball server, then it quits and must be restarted. There are not hints what is going on.
* Are there any "commands", similar to the bitcoing QT wallet, were some advanced actions could be triggered like blockchain check, re-download,...
Technically, Byteball are very sophisticated, but those blurry or not available information makes it hard to trust it 100%. I don't like to reverse-engineer the sourcecode to get more hints.
