Benefits for Community (optional)
- Since 4Q24, TEB has acted as the Korean ambassador of Metis, building its retail presence from virtually none to a community of more than 1,500+.
- TEB has utilized its Learn2Earn platform - benft.io - to create contents and campaigns focusing on Metis. 25+ unique articles were written and 2 quests (eg. performing testnet transactions for the Community Testing event) were executed, which can be referred to here. .
- TEB has set up and managed Metisβ Korean Telegram announcements channel and group chat, where more than 1,000+ posts from Metisβ global channels were translated and uploaded for a community of 1,500+ combined users.

- TEB will continue to commit to the aforementioned community engagements. As a Sequencer however, TEB will leverage B-Harvestβs expertise in developer relations to host offline events in the nature of open lectures and hackathons to target Korean devs. This would enable TEB to expand its ecosystem builder role, additionally serving as tech advisor of Metis for the Korean community.
Integration Roadmap
We will add a few processes to the standard integration approach created internally at B-Harvest. These are as follows:
- Cloud selection and security rating
-
Select an instance and cloud that meets the standard specifications recommended by Metis Sequencer and the characteristics of your sequencer.
-
Follow the standard security settings for instances on the Sequencer node, including basic OS security and administrator tiers
- Automation deployment
- Automate the Metis Sequencer setup guide as much as possible.
- Choose and work with infrastructure tools that match the characteristics of your sequencer, or develop your own. These can be open-sourced in the future.
- In addition to the Metis Sequencer nodes, the monitoring and alerting systems are included in this automation.
- Enable monitoring
- Identify basic metrics for a well-functioning sequencer, and integrate them into Grafana and Prometheus
- Analyze the appropriate thresholds for those metrics, and apply them to alerting
- Deploy the product
- Once all the preliminary work is done, deployment is the next step.
- For node configuration files, follow the usual conventions
- For other additional items, deploy according to your own conventions
- Further maintenance
- As issues arise during the deployment and post-deployment phase, we share and collaborate with other sequencers and the community.
