I wanted to back up the blockchain on my hard drive as it took around 50 GB on my laptop. I did so and deleted all the
blk000.dat and the
rev000.dat from (
~/Library/Application Support/Bitcoin/) which are saved on my hard drive. Apparently this was a stupid mistake as I cannot open Bitcoin QT anymore. I therefore re-transfered everything back to the same folder. But nothing happens, and Bitcoin Core does not open.
After looking around, many are mentioning a
bootstrap.dat file which correspond to the block chain. I cannot seem to find this file anywhere on my laptop.
Any clues? thanks a lot!
