Configure Validator List Threshold

A rippled server uses validators that meet a minimum intersection threshold between UNL publishers. This means a server only uses validators that exist on a number of validator lists, as defined by the server owner. {% badge href="https://github.com/XRPLF/rippled/releases/tag/2.4.0" %}New in: rippled 2.4.0{% /badge %}

By default, the minimum threshold is calculated as follows:

• floor(validator_list_keys / 2) + 1
• If there are only 1 or 2 validator_list_keys, the threshold is 1.

Modify the Validators File

1. Edit the validators.txt file. The recommended installation places this file at:

   /etc/opt/ripple/validators.txt
   

2. Add the following stanza and a valid threshold number.

   [validator_list_threshold]
   0
   

Be sure to save the changes and restart your server.

{% admonition type="info" name="Note" %}If this value is 0 or isn't set, the threshold will be calculated using the default method. The value also can't be larger than the number of validator_list_keys.{% /admonition %}
