Key Highlights
- TRON released GreatVoyage-v4.8.2.3, also known as Anaxagoras, on September 30 as a mandatory upgrade for node operators.
- The update optimizes smart contract storage access and BN128 pairing performance in specific edge cases.
- Node-generated JSON response parsing has also been improved as part of the release.
TRON, a Layer-1 blockchain platform, released GreatVoyage-v4.8.2.3, also known as Anaxagoras, as a mandatory upgrade for node operators on September 30. The release requires operators to upgrade as soon as possible to maintain uninterrupted node synchronization.
According to the official announcement, the update includes three primary changes: optimization of smart contract storage access in edge cases, optimization of BN128 pairing performance in edge cases, and improved parsing of node-generated JSON responses.
Standard node upgrade process
All FullNodes, including block-producing Super Representative nodes, are directed to follow a defined sequence of steps. Operators may prepare the new version package by downloading the compiled java-tron executable from the java-tron GitHub Releases page or by compiling from source code. Recommended downloads are FullNode-x64.jar for x86-64 systems or FullNode-aarch64.jar for ARM64 systems.
After signature verification according to the java-tron Signature Verification guide, the file is renamed to FullNode.jar. For source compilation, the process involves cloning the repository, switching to the target version branch, and running the build command ./gradlew clean build -x test. The resulting FullNode.jar appears in the build/libs/ directory.
Operators then stop the running node by identifying the process ID with ps -ef | grep java and issuing kill -15 <PID>. First-time deployments skip this step.
TRON advises full backup before upgrade
A full backup is strongly recommended before proceeding. This includes renaming the current executable with a timestamp, creating a tar archive of the output-directory database, and renaming the configuration file with a timestamp. The new FullNode.jar is copied into the working directory.
Replacement of the configuration file with the latest version from the release is optional but recommended for compatibility. Custom settings such as private keys or keystore paths are then merged. The existing database may remain in place or be restored from a pre-built snapshot. Nodes are restarted according to documentation for block-producing Super Representative nodes or regular FullNodes on the TRON main network.
After startup, operators monitor synchronization by comparing local block height, obtained via the /wallet/getnowblock API call to http://127.0.0.1:8090/wallet/getnowblock, against the mainnet height shown on TRONSCAN. Logs are checked for errors. Synchronization is complete when the heights are nearly identical. If issues prevent proper operation, operators are instructed to restore from the backups created earlier and submit a GitHub issue or report the problem to the TRON community. Primary and Backup Node Upgrade Procedure For primary/backup configurations, a rolling upgrade strategy is specified to maintain availability.
The backup node is upgraded first using the full standard process. Once it has synchronized, the master node process is stopped, allowing the backup to become the active node. The original master node is then upgraded. If the new active node fails, the original master is restarted immediately, and logs from the failed node are retained for troubleshooting.
After the original master has upgraded, started, and synchronized, the current active node is stopped so the original master resumes its active role. The backup node is then restarted in its backup capacity.
