Checkpoints

How To Sync Quickly

You can sync a fresh chain from 0 much quicker by loading "checkpoints" with your daemon.

Setup

• Right click this link and choose Save link as... to download the latest checkpoints.csv.
• Place checkpoints.csv in the same folder as your Plenteumd daemon
• You can get Plenteumd from here if you don't have it already: https://github.com/plenteum/plenteum/releases
• Make sure you shut down any GUI wallets, or any other instances of Plenteumd.

Usage

Windows

• First, open a command prompt in the same directory as Plenteumd.
• This can easily be done by moving to the Plenteumd directory in Windows Explorer, then typing cmd in the search bar and hitting enter:
• Finally, type Plenteumd.exe --load-checkpoints checkpoints.csv in the command prompt.

Linux, Apple

• First, open a command prompt in the same directory as Plenteumd.
• You can use the cd command to change to this directory. For example, cd downloads/plenteum-v0.3.0
• Alternatively, your file manager may provide the ability to open a terminal in your current directory. Navigate to the folder with Plenteumd in, and try right clicking, to see if you can open a terminal there:
• Finally, type ./Plenteumd --load-checkpoints checkpoints.csv in the terminal.

Expected Output

If you did the steps correctly, you should see something like this output.

2018-May-13 11:58:39.654478 INFO    Welcome to Plenteum v0.4.5 ()
2018-May-13 11:58:39.654914 INFO    Module folder: Plenteumd
2018-May-13 11:58:39.655249 INFO    Loading Checkpoints for faster initial sync...
2018-May-13 11:58:40.854979 INFO    Loaded 251786 checkpoints from checkpoints.csv

• Plenteumd will then start syncing from checkpoints.
• If you are using the CLI wallet, then you can just wait for it to finish syncing, and open your wallet.
• If you are using a GUI wallet, let it finish syncing, then open your GUI wallet.

Common Errors

Invalid checkpoint file format

2018-May-13 12:10:08.339667 ERROR   Invalid checkpoint file format
2018-May-13 12:10:08.341758 ERROR   Exception: Failed to load checkpoints

• If you see output like the above, the file you are opening is either not a .csv file, or hasn't been downloaded correctly.
• Ensure you downloaded the file by right clicking, and choosing Save link as....
• If you incorrectly chose the wrong file, you can accidentally download a html page instead.
• When you open up the file, it should have lots of lines like this:

0,4755c750a1ed8535ba1789570899720f3cd010ccf7ab70a1a2d2d53f298eafd5

• If you absolutely can't get it working, you can make a new text file, copy all the content from here into it: https://raw.githubusercontent.com/plenteum/checkpoints/master/checkpoints.csv
• Then save as checkpoints.csv (Select filetype: all files in windows)

• If you see output like the above, it means the file isn't present in the directory you are in.
• Make sure you have placed the checkpoints.csv file in the same directory as Plenteumd.

Plenteumd.exe is not recognized / No such file or directory

C:\Users\gentoo>Plenteumd.exe --load-checkpoints checkpoints.csv
'Plenteumd.exe' is not recognized as an internal or external command,
operable program or batch file.

bash: ./Plenteumd: No such file or directory

• If you see output like one of the above, it means your terminal isn't in the same folder as the Plenteumd program.
• You can type pwd to see what folder you are currently in.
• Try following the steps above to get into the right folder, then try again.
• If you type ls, you should see the Plenteumd program, if you are in the correct folder:

[plenteum-v0.3.0]λ ls
miner  poolwallet  zedwallet  Plenteumd  wallet-service

• If you see output like the above, something else has got the database open already.
• Make sure you have closed down any other Plenteumd's, GUI wallets, and wallet-service.
• Use a task manager to help you find any which might be running in the background, then try again.
