+# Distance rule evaluation
+
+The [distance rule](https://duniter.org/blog/duniter-deep-dive-wot/) is computationally too heavy to be handled by the runtime. Therefore it is computed offchain using the distance oracle.
+
+Distance evaluation is operated on a voluntary basis by individual smiths. Since evaluators can lie or make errors, the result considered for applying the distance rule is the median of results published by the different evaluators.
+
+## Running distance evaluation
+
+Any smith member authoring blocks can run a distance evaluation oracle. It is better to have a machine more powerful than the reference machine.
+
+The simplest way is to run the oracle on the same machine as Duniter.
+
+Build the oracle:
+
+    cargo build --release -p distance-oracle
+
+It will be available at `./target/release/distance-oracle`. Move it to somewhere appropriate.
+
+Add this line to your cron with the command `crontab -e`: (add option `-u <user>` to edit another user's cron)
+
+    4,24,44 * * * * /absolute/path/to/distance-oracle
+
+The precise hours don't matter so you can pick random values, but it should run at least one time per hour, and running it more often decreases the risk of problem in case of missing blocks or temporary network failure.
+
+If the evaluation ran successfully in a session, the next runs in the same session won't re-evaluate the same data.
+
+No additional configuration is needed for Duniter.
