- Right click this link and choose
Save link as...
to download the latest checkpoints.csv. - Place checkpoints.csv in the same folder as your TurtleCoind daemon
- You can get TurtleCoind from here if you don't have it already: https://latest.turtlecoin.lol
- Make sure you shut down any GUI wallets, or any other instances of TurtleCoind.
- First, open a command prompt in the same directory as TurtleCoind.
- This can easily be done by moving to the TurtleCoind directory in Windows Explorer, then typing
cmd
in the search bar and hitting enter:
- Finally, type
TurtleCoind.exe --load-checkpoints checkpoints.csv
in the command prompt.
- First, open a command prompt in the same directory as TurtleCoind.
- You can use the
cd
command to change to this directory. For example,cd Downloads/turtlecoin-v0.5.0

- Finally, type
./TurtleCoind --load-checkpoints checkpoints.csv
in the terminal.
If you did the steps correctly, you should see something like this output.
