 ## How can I avoid using a prepared blockchain and validate myself?

 ## I have the full blockchain on another computer. How do I copy it to the RaspiBlitz?
 
-Copying a already synced blockchain from another computer (for example your Laptop) can be a quick way to get the RaspiBlitz started or replacing a corrupted blockchain with a fresh one. Also that way you synced and verified the blockchain yourself and not trusting the RaspiBlitz FTP/Torrent downloads (dont trust, verify).

 One requirement is that the blockchain is from another bitcoin-core client with version greater or equal to 0.17.1 with transaction index switched on (`txindex=1` in the `bitcoin.conf`).

 ## Why is my "final sync" taking so long?
 
-First of all if you see a final sync over 90% and you can see from time to time small increase - you should be OK ... this can take some looong time to catch up with the network. Only in the case that you activly choose the `SYNC` option in the `Getting the Blockchain` a final sync under 90% is OK. If you did a torrent, a FTP or a copy from another computer and seeing under 90% somthing went wrong and the setup process is ignoring your prepared Blockchain and doing a full sync - which can almost take forever on a raspberryPi.

 So if something is wrong (like mentioned above) then try again from the beginning. You need to reset your HDD for a fresh start: SSH in as admin user. Abort the final sync info with CTRL+c to get to the terminal. There run `sudo /home/admin/XXcleanHDD.sh -all` and follow the script to delete all data in HDD. When finsihed power down with `sudo shutdown now`. Then make a fresh SD card from image and this time try another option to get the blockchain. If you run into trouble the second time, please report an issue on GitHub.

 ## What is the "Base Torrent File"?
 
 Inspired by the website getbitcoinblockchain.com we use one of their base torrent files to have a basic set of blocks - that will not change for the future. This torrent contains most of the data (the big file) and we dont need to change the torrent for a long time. This way the torrent can get establish a wide spread seeding and the torrent network can take the heavy load.

 It is safe to close the terminal window (shutdown your laptop) while the RaspiBlitz is doing the torrent download. To check on progress and to continue the setup you need to ssh back in again. 
 
 You can cancel the torrent download by keeping the key `x` pressed. Then the download will stop and you will be asked if you want to keep the progress so far. This makes sense if you need to shutdown the RaspiBlitz and you want to continue later or when you want to try another download option but want to keep the option to continue on torrent if the other option is slower or not working.
