This is a walk-through for how to perform the mandatory upgrade of the xxnetwork-chain binary to the latest version as of October 15, 2022, version 0.2.5-1,
!! The network is running, but in order to ensure it doesn’t stop we need 2/3rds of the network to update and run the new binary by 07:00 AM UTC 15th October. !!
Releases are located at …
This is a mandatory upgrade.
This walk-through assumes the node and gateway computers were configured per the Node Handbook
The entire process shouldn’t take a novice Linux user more than 10-15 minutes.
If you’re not familiar with Linux, I suggest you proceed through the steps in the order they appear.
Sample output is provided for commands that generate output to assist but some sample output will not be exactly as shown.
Please review the following process at least once to get a feel of what is required.
The xxnetwork-chain v0.2.5-1 Binary Upgrade Procedure:
Step 1: On BOTH computers get the current version of the xxnetwork-chain binary by running the following command.
$ /opt/xxnetwork/bin/xxnetwork-chain --version xxnetwork-chain 0.2.5-a26979c-x86_64-linux-gnu
If the previous command returns
xxnetwork-chain 0.2.5-1-8bcb0e65356, then you should not continue. You are running the latest version.
Step 2: Stop all of the xx network services on BOTH computers:
2a. On the NODE computer run …
$ sudo systemctl stop xxnetwork-cmix $ sudo systemctl stop xxnetwork-chain
2b. On the GATEWAY computer …
$ sudo systemctl stop xxnetwork-gateway $ sudo systemctl stop xxnetwork-chain
Step 3: Run the following series of commands as they appear on BOTH the node and gateway computers:
3a. Change to the directory where the xx network binaries are located …
$ cd /opt/xxnetwork/bin
3b. Backup the existing xxnetwork-chain binary …
$ mv -v xxnetwork-chain xxnetwork-chain.bak renamed 'xxnetwork-chain' -> 'xxnetwork-chain.bak'
3c. Download version 0.2.5-1 of the xxnetwork-chain binary …
$ curl -L -o xxnetwork-chain -O https://github.com/xx-labs/xxchain/releases/download/v0.2.5-1/xxnetwork-chain % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0 100 81.3M 100 81.3M 0 0 8048k 0 0:00:10 0:00:10 --:--:-- 12.8M
3d. Verify the checksum of the xxnetwork-chain binary …
$ sha256sum xxnetwork-chain 6f96076b48e75bb43d0598a68b5482e0648b41cec0c38a6d16d9cf17742ad596 xxnetwork-chain
The output above is the unique checksum for the 0.2.5-1 binary file and must be 6f96076b48e75bb43d0598a68b5482e0648b41cec0c38a6d16d9cf17742ad596. If anything else is returned, the download may have failed and you likely just need to re-run the
curl command. If it still does not match after trying to download again, please stop and ask for assistance here or on the xx Network Discord Server.
3e. Make the xxnetwork-chain binary executable …
$ chmod -v +x xxnetwork-chain mode of 'xxnetwork-chain' changed from 0664 (rw-rw-r--) to 0775 (rwxrwxr-x)
3f. Ensure the downloaded binary is version 0.2.5-1 …
$ /opt/xxnetwork/bin/xxnetwork-chain --version xxnetwork-chain 0.2.5-1-8bcb0e65356
3g. Start the xxnetwork-chain service …
$ sudo systemctl start xxnetwork-chain
3h. Check the chain.log to ensure the process is running and is synced …
$ tail -F /opt/xxnetwork/log/chain.log
Depending on how log the previous steps took to complete, you may need to wait a few minutes before you see the desired messages. You want to ensure you see

Step 4: Start the gateway and cmix services:
4a. On the GATEWAY computer …
$ sudo systemctl start xxnetwork-gateway
4b. On the NODE computer …
$ sudo systemctl start xxnetwork-cmix
That completes the steps required to upgrade the xxnetwork-chain binary to version 0.2.5-1.
To check the status of the xx network services you can run …
$ systemctl status xxnetwork-*
To check the xx network processes are running you can run …
$ ps -A | grep xxn
