Sequencer Proposal: TEB

teb · April 30, 2024, 12:20pm

TEB is an Web3 advisory firm that specializes in ecosystem development and Go-To-Market strategies in Korea, providing services to 15+ blockchain projects, including Metis. TEB has been leading the promotion and branding of Metis in Korea through 1) localized content creation, 2) KOLs and media partners activation, 3) community management, and 4) offline event support.
TEB is keen to participate as a node operator for the Sequencer Pool by utilizing its validator arm B-Harvest. B-Harvest (bharvest.io) is a blockchain validator within the Cosmos and Ethereum ecosystem, expanding its expertise into the development of DeFi protocols and conducting R&D on Cosmos SDK and EVM.

TEB supports its blockchain layer partners in the form of node operation through TEB’s validator business arm in B-Harvest.
B-Harvest provides validation services for multiple dPoS networks to ensure decentralized governance. The list of networks include: Archway, Axelar, Band Protocol, Canto, Celestia, Coreum, Cosmos Hub, Injective, Kava, MultiversX, Neutron, Nibiru, Noble, Osmosis, Rarimo, Secret Network, Stride, Sui, Vega, Wemix, and Xpla.
B-Harvest currently has total staked assets of $83M with 25,000 delegators across Cosmos based networks, and $47M with 3,000 delegators across other L1 networks, committing to an uptime of 99.9%.
B-Harvest leverages both public clouds (AWS, GCP, Azure) and baremetal clouds (OVH, Vultr, Leaseweb, PhoenixNAP) across Korea, US, and Europe regions in order to distribute our servers to different locations with proper HW specs and failover plan.

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 Metis’ Korean Telegram announcements channel and group chat, where more than 1,000+ posts from Metis’ global channels were translated and uploaded for a community of 1,500+ combined users.
TEB was instrumental in securing sponsorship titles for Metis during EthSeoul and SheFi Korea. TEB staff actively supported during the events, leading booth duties and promoting Metis’s sponsor role through its KOLs and media partners.
TEB will continue to commit to the aforementioned community engagements. As a Sequencer however, TEB will leverage B-Harvest’s 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.

We will add a few processes to the standard integration approach created internally at B-Harvest. These are as follows:

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

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.

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

As issues arise during the deployment and post-deployment phase, we share and collaborate with other sequencers and the community.
