Guide to Factory Resets • Manual • docs.urbit.org

An important concept on the Ames↗ network is that of continuity. Continuity refers to how ships remember the order of their own network messages and the network messages of others -- these messages are numbered, starting from zero. A factory reset is when ships on the network agree to forget about this sequence and treat one or more ships like they are brand new.

Factory Resets

Ships on the Ames network sometimes need to reset their continuity. A factory reset (hereafter just called a reset) is when an individual ship announces to the network: "I forgot who I am, let's start over from scratch." That is, it clears its own event log and sends an announcement to the network, asking all ships that have communicated with it to reset its networking information in their state. This makes it as though the ship was just started for the first time again, since everyone on the network has forgotten about it.

Resets often fix connectivity issues, but should only be used as a last resort. Before performing a reset, look at alternative fixes in the Ship Troubleshooting guide. Also reach out for help in the Help channel in the Urbit Community group ~bitbet-bolbel/urbit-community to see if there is another option. Connectivity issues are typically related to a bug, and you may be able to help us fix it by emailing us at [email protected].

There are two separate sequences of actions you need to take in order to reset. One flow is for when you wish to keep Ethereum ownership address of the ship the same, and the other is for when you are transferring the ship to a new Ethereum ownership address. We make the emphasis about the Ethereum ownership address as changing your proxies↗ does not require a reset.

If you will be keeping your ship at the same Ethereum ownership address and would like to perform a reset, follow the steps below.

Go to bridge.urbit.org↗ and log into your identity.
Click on OS: Urbit OS Settings at the bottom, then click Reset Networking Keys.
Check the Breach Continuity box. Click Reset Networking Keys, and then click Send Transaction and wait for the progress bar to appear.
Download your new keyfile following these instructions: Generate your keyfile.
Delete or archive your old pier↗.
Proceed to boot your ship with the new keyfile.
Delete your keyfile after successfully booting.

If you are transferring a ship to a new Ethereum ownership address you will have the choice as to whether or not you want to reset. This is to cover the case when you are transferring to another address you own. The process here is slightly different.

Go to bridge.urbit.org↗ and log into your identity.
Click on ID: Identity and security settings at the bottom, then click Transfer this point.
Enter the new Ethereum address you would like to transfer ownership to. Click Generate & Sign Transaction, then click Send Transaction and wait for the progress bar to complete.
Logout of your current session in Bridge by clicking Logout at the top, and then login to your new ownership address.
From here, following the directions on how to Accept your transfer, Set your networking keys, and Generate your keyfile. The option whether or not to reset is in the Accept your Transfer step.
Delete or archive your old pier↗.
Proceed to boot your ship with the new keyfile.
Delete your keyfile after successfully booting.

Network Resets

Network resets were events where all ships on the network were required to update to a new continuity era. Network resets happened when an Arvo update was released that could not be implemented via an OTA update↗. The continuity era is given by an integer in Ames that is incremented when the network resets. Only ships with the same such value are able to communicate with one another. The most recent network reset occurred in December 2020, and we expect it to have been the final one.

If another network reset does occur, we will provide accompanying documentation on what to do to transfer your ship and all of its data to the new era.

Breaches

Factory resets used to be called breaches, and you may find this terminology still used in some places. This is an identical concept - only the name differs.
