Chronicle Replication

An individual Chronicle can replicate multiple other Chronicle instances. The setup process is simpler than cross-signing.

First, run the following command:

php bin/replicate.php \
    --url=http://target-chronicle \
    --publickey=[public key of target chronicle] \
    --name=[whatever you want to refer to it]

Then, make sure you set up a cron job to run bin/scheduled-tasks.php at a regular interval (e.g. every 15 minutes):

/15  * /path/to/chronicle/bin/scheduled-tasks.php

How to Access a Replicated Chronicle

Visit https://your-chronicle-domain/chronicle/replica to see an index of all other Chronicles being replicated. Each entry should have a list of URLs that can be accessed to query the replicated data.

Scheduled Attestation

If you have replication enabled, your Chronicle will periodically write a summary of all replicated Chronicles onto itself. To change the frequency, change the scheduled-attestation setting in local/settings.json. A valid frequency looks like "7 days" or "1 week + 3 days". Relevant PHP Documentation.

To disable scheduled attestation, simply remove the scheduled-attestation directive in local/settings.json. Alternatively, set it to null or false.
