As the crucial underlying infrastructure of a public chain ecosystem, the mainnet’s performance determines its development. Since its official launch on February 25, 2019, the IOST Mainnet has been operational for over four years. During this period, the IOST development team has consistently pursued innovative approaches, conducting multiple version updates and optimizations. The IOST Mainnet has witnessed rapid growth in terms of DApp count, mainnet accounts, and transaction volume, positioning itself as a globally recognized Top 4 DApp public blockchain platform.
We are happy to announce the launch of Mainnet Olympus v3.10.1 today, which is a non-compatible upgrade. All block-producing nodes must complete the upgrade by September 10th, while non-block-producing nodes are also advised to upgrade.
Changelog:
- This version primarily enhances the libp2p module by introducing yamux support alongside mplex.
- In the next version, we will be removing mplex support.
- To learn more about the details of this update, please refer to https://github.com/iost-official/go-iost/releases
Notes:
- All block-producing nodes are required to complete the upgrade by September 10th.
- When manually upgrading, if you encounter a docker panic during the image reconstruction, please check if “security-opt” is set to seccomp:unconfined. The specific command is as follows (assuming the iServer data directory is set to the default value /data/iserver): docker run -d — name iserver -v /data/iserver:/var/lib/iserver -p 30000–30003:30000–30003 — security-opt seccomp:unconfined iostio/iost-node

Follow the instructions published on the IOST developer documentation.
Following successful execution of the upgrade, hash, and version scrutiny can be effectuated via the following command:
- docker exec -it iserver iwallet state | grep -E “codeVersion|gitHash”
The result should be as follows:
- “gitHash”: “d7fdfb3747677f82e148cb4a90cbab90c339b149”, “codeVersion”: “3.10.1”
