This is a walk-through for how to perform the update of the xxnetwork-chain binary to the latest version as of July 05, 2024, version 0.2.6.
Releases are located at …
Notes:
-
If you are still on version
v0.2.5
or earlier, please read the following warning.
The new runtime 206 requires host functions that were introduced in releasev0.2.5-1
. This means that once the runtime gets activated on-chain, chain binaries with versionv0.2.5
or older will panic and crash. Please update your binary if your version is not at leastv0.2.5-1
. -
This upgrade is not mandatory with the exception noted above, but it is recommended.
-
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.
-
“Example Output:” is provided for commands that generate output to assist but some sample output may not be exactly as shown.
-
Please review the following process at least once to get a feel of what is required.
The xxnetwork-chain v0.2.6 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
Example Output:
xxnetwork-chain 0.2.5-2-81384c39acd
If the previous command returns xxnetwork-chain 0.2.6-617b35d134c
, then you should not continue. You are running the latest version.
Step 2: Stop the xx network-chain services on BOTH computers:
2a. On the NODE computer run …
$ sudo systemctl stop xxnetwork-chain
2b. On the GATEWAY computer …
$ 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
Example Output:
renamed 'xxnetwork-chain' -> 'xxnetwork-chain.bak'
3c. Download version 0.2.6 of the xxnetwork-chain binary …
$ curl -L -o xxnetwork-chain https://github.com/xx-labs/xxchain/releases/download/v0.2.6/xxnetwork-chain
Example Output:
% 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
Example Output:
28f9de76476d3dbca24e0360686562b5f97b004a0c0a842bd43ec18989c5195c xxnetwork-chain
The output above is the unique checksum for the 0.2.6 binary file and must be 28f9de76476d3dbca24e0360686562b5f97b004a0c0a842bd43ec18989c5195c. 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
Example Output:
mode of 'xxnetwork-chain' changed from 0664 (rw-rw-r--) to 0775 (rwxrwxr-x)
3f. Ensure the downloaded binary is version 0.2.6 …
$ /opt/xxnetwork/bin/xxnetwork-chain --version
Example Output:
xxnetwork-chain 0.2.6-617b35d134c
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 ✨ Imported
and 💤 Idle
messages scrolling by.
Example Output:
