Good afternoon, prompt please where to download the block chain for the wallet Nu under windows?, well, a very long time to sync .
The reason, I do not understand, usually from my practice “blkindex.dat” is damaged after a critical shutdown windows and then we can say out of the blue once on my purse began a period of POS.
Please check this thread: Download NuBits blockchain (bootstrap)
It is only half of the current blockchain, but I suppose that it better than starting from scratch.
It’s likely that the wallet will crash in windows when it gets toward 80-90% or so. Let us know if its also the case for you.
