Load Checkpoints

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
Under Recent blocks you will find the Blocks and the corresponding Hashes. This is an example Checkpoint: 269588,dd0e5f6232fde383e8249dfefb3d1d8e60834cac0edeeb26ce3179ee7fbbe7c6
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) by following below instruction.
