Freedom-Gemini Launched on Mainnet – OriginTrail
After verifying the version is at 4.0.0, restart the node one more time to finish the update with this command:
Congrats. You are all set.
If you want to get the auto-update as quickly as possible, you can trigger it by restarting your node.
Prerequisites: Auto-update is enabled and the node is running in a Docker container.
If you do not want to wait for your node to update itself, you can trigger the update process yourself by restarting your node with this command:
The node will detect the new version and will start the auto-update process.
If the update is successful, the node will restart itself and you should see this message in the logs to verify the Version check: local version 4.0.0, remote version: 4.0.0.
Next, restart the node manually. To finish the process, run the following command:
docker restart otnode
Congrats. You are all set.
The Manual Way
Proceed here if you don’t have auto-update enabled.
Prerequisites: The node is running in a Docker container.
The default settings on the v4.0 ODN nodes come with an initial set of values, enabling a smooth transition from the OriginTrail Vostok Mainnet version v2.0.59. The most important update regarding setting up your node reflects the pricing configuration options, which is now possible through one single parameter in your node, the Lambda factor.
The Lambda factor can be set for both the Data Creator (DC) and Data Holder (DH) services on the network. If your node is operating solely as a DH node, you just need to set the DH Lambda according to your preference. Lambda approximates the complex factors for pricing (data lifespan, dataset size, and token withdrawal cost) on the network into one parameter. As each node sets its own Lambda factor, a market for DH nodes gets established around DH services where DC nodes need to publish datasets to the network with a Lambda value that a majority of the nodes on the network will accept. Therefore, an overly optimistic, high Lambda (high cost) could cause your node to be outpriced by other ODN nodes and not receive enough jobs to be profitable, while a Lambda set too low might mean an insufficient ROI. You can change the Lambda factor of your node at any time, which will be taken into account for all the jobs your node will try to engage in. Previously agreed upon jobs will be unaffected.
If you are operating a DC node, you should make sure to set the DC Lambda factor to an appropriate value so that the network will accept your offers.
Additional parameters include the maximum data lifespan your node will accept for data holding offers, the maximum dataset size your node will accept (currently set at a conservative value of 3 MB, though iteratively will grow to hundreds of MBs in the coming incremental releases), and other parameters that have been set by default to values to accommodate the nodes with the lowest hardware abilities (minimum hardware requirements as listed on the website).
The development team will closely be monitoring the statistics and telemetry from the new Freedom-Gemini mainnet and iteratively implement further performance improvements, which will be reflected in the default node parameters. The adaptations and improvements will be made according to the same hardware requirements currently required by the ODN nodes. It is recommended to start with the default configuration values transitioning from OriginTrail Vostok Mainnet and gradually change them according to the latest developments.
To easily setup and update the settings on your node, you can utilize the Houston application, which can be obtained on the new Houston v4 Github repository. Houston is an open-source web application that runs on your local computer and allows you to manage all aspects of your running node. When updating to the newest version of the node, please make sure to also download the latest version of Houston as the old version will no longer work with the new nodes.
