Title: Advanced commands Order: 9 Date: 2022-10-04 Slug: advanced_commands Authors: elois

Advanced commands

Before reading this page, first read the on-board help in Duniter, it meets the most common needs:

duniter help

If you are new to Duniter, or/and you just want to configure your network properly, read this page instead: Configure Duniter server variant.

This page is intended for advanced users, advanced testers and developers.

Some advanced options are hidden in the embedded help (duniter help) because they are rarely used and/or are mainly intended for advanced testers and developers.

Some commands are not available via the Duniter binary and need to call directly the NodeJs part.

Hidden options

This part lists the options accessible via the Duniter binary but hidden in the help.

Hidden sync options

These options must be used with the sync sub command.


Check all DUPB rules (very long).


Allow to synchronize on nodes with local network IP address.

Hidden config options

These options must be used with the config sub command.


Number of cores uses for proof-of-work computation


Add given endpoint to the list of endpoints of this node.


Remove given endpoint to the list of endpoints of this node.

WS2P preferred/privileged options

These options are described in a dedicated page: WS2P: preferred and privileged nodes


Disable WS2P Private.


Enable WS2P Private.

--ws2p-socks-proxy <host:port>

Use Socks Proxy for WS2P Private


Remove all proxies options

WS2P TOR options

To have your Duniter node use Tor for outgoing connections it makes with other nodes, just set up a Tor proxy and choose a policy for normal ws2p access points (the --reaching-clear-ep option):

duniter config --tor-proxy localhost:9050 --reaching-clear-ep tor

You will also need to install the Tor Browser or Tor Standalone on the same machine. By default, Tor listens on localhost on port 9050. If you change your Tor configuration you will obviously need to change the Duniter configuration accordingly.

You can also choose a mixed node, which will contact the regular access points in plain text, so it will only use Tor to contact .onion access points:

duniter config --tor-proxy localhost:9050 --reaching-clear-ep clear

Finally 3rd choice, you can choose to contact only the .onion access points, the clear access points will never be contacted:

duniter config --tor-proxy localhost:9050 --reaching-clear-ep none

/!\ Each time you change one of these two options you must repeat the other one at the same time or it will be reset!

Finally, to remove your Tor configuration and return to a classic node:

duniter --rm-proxies

You can also decide to encapsulate Duniter in a Tor VM as whonix, in which case you will need to inform Duniter that it will be able to contact .onion access points by enabling the `--force-tor' option:

duniter config --force-tor --reaching-clear-ep tor|none

Hidden service

Just enter the .onion address of your hidden service in the --ws2p-remote-host option.

Hidden commands and more hidden options

The following commands and options are not accessible via the duniter binary. The NodeJs code must be called directly for them.

For this use the embedded NodeJs :

/opt/duniter/node/bin/node duniter_js <hidden-command>

If you compiled Duniter yourself, you don't have any NodeJs embedded, then use the version of NodeJs you used to compile Duniter.

Not all commands and options are listed here, if you don't find what you need:

  1. Search in duniter_js --help.

  2. Search into the Duniter's code itself.

  3. Ask for help on the Duniter forum.

sync --memory

Perform synchronization in memory only. Synchronization will not be stored on the hard disk. This option is useful for a quick blockchain integrity check when combined with the --cautious option.

duniter_js sync 443 --cautious --memory

Generate a block manually

Generates the next block from the pool data and the current block, performs the working proof for the requested difficulty and then submits the resulting block to a node.

duniter_js gen-next 10901 74

This command generates the next block, sends it to node and calculates the working proof with 74 trouble (footprint beginning with 4 zeros).

Option --show

Displays the calculated block before the proof of work and submission to the network. Controls its contents.

duniter_js gen-next 10901 74 --show

Option --check

Modifies the behaviour of the command: it no longer produces proof of work nor submits the block to the network. Instead, it generates the block and checks if it is acceptable by a node.

duniter_js gen-next --show --check

Generate genesis block

Generates block #0 automatically, including a maximum number of members:

duniter_js gen-root 10901 74

Generates block #0 by manually selecting members to include:

duniter_js gen-root-choose 10901 74
