If you are using MultiDoge and are stuck far behind in syncing, then this guide is for you. Even if you are currently already synced it's worth following this guide to be prepared for future re-syncs, but you can skip some steps. These new checkpoints contain blocks up to Jan 30th 2021. If you are trying to sync a wallet that has been created before around summer 2016, then sadly this won't really help you.
- Close MultiDoge completely.
- Download this file: multidoge.checkpoints
- Copy this file to the MultiDoge data directory. See below for the path. Overwrite the existing file. If you are already synced, you're done at this point, If not, continue.
- Start MultiDoge.
- In the MultiDoge menu, select "Tools", then "Reset Blockchain and Transactions".
- In the tab that shows up click the "Reset blockchain and transactions".
Congrats, you just updated your checkpoints! If after step 6 you don't see your balance anymore, don't worry. It will show up once the sync is completed.
You may need to enable showing hidden files and folders to find these.
C:\Users\<your_user_name>\AppData\Roaming\MultiDoge
/Users/<your_user_name>/Library/Application Support/MultiDoge
/home/<your_user_name>/MultiDoge or /home/<your_user_name>/.config/MultiDoge
I have signed the checkpoint file with my PGP key found here: https://github.com/dogecoin/dogecoin/blob/master/contrib/gitian-keys/langerhans-key.pgp So in case you're concerned about the legitimacy of the file you can verify the attached signature.
Thank you, glad I found this.
