You can start your Qwertycoin Daemon (>= 5.0.1) with a CSV which contains at least 1 Checkpoint. This can be useful to solve synchronization problems.
A checkpoint is the combination of block height and the associated block hash. You can find these informations on our Explorer: https://explorer.qwertycoin.org
Recent blocks you will find the Blocks and the corresponding Hashes.
This is an example Checkpoint:
We have provided an API which automatically creates the most recent block in checkpoint format. You can choose between a single line that you can use to create the CSV yourself, or you can download a CSV file – checkpoint (CSV Export).
How to start Daemon with Checkpoint.csv
Save this checkpoint.csv in the folder with your qwertycoind.exe
Open a CMD or a Terminal and launch your Daemon with the following command:
qwertycoind --load-checkpoints checkpoint.csv
Your Daemon launch and you will see a message like this:
Loading checkpoints from file...
Loaded 1 checkpoint from checkpoint.csv
Your daemon will now sync without an error to the checkpoint height. If the error occurs again, repeat steps 1 to 5 with new checkpoint.
