What other networks are you running validators for?

Etherum, Polygon, and Pokadot. Experienced in Startware DAC committees.

Based on your participation in any previous testnets, mainnets, are there any best practices to be aware of? What are some things that made previous testnets, mainnet launches successful and/or things to avoid that have gone poorly?

Yes. We have strict processes in place to ensure the success of previous testnets and mainnet launches. Here are a few highlights from our system:

  • Release Process:
    • Establish a clear release process with well-defined milestones, including alpha and beta testing phases, to ensure thorough testing and bug fixing before the mainnet launch.
    • Conduct multiple iterations of testing, allowing developers and external participants to provide feedback and identify potential issues.
    • Implement a version control system to track changes and maintain a stable codebase.
  • Monitoring Process:
    • Implement a comprehensive monitoring system to track the health and performance of the network during the testnet and mainnet phases.
    • Monitor key metrics such as block production, transaction throughput, latency, and resource utilization to identify potential bottlenecks and performance issues.
    • Set up alerts and automated notifications to respond quickly to critical events or abnormal behavior.
  • Production Checklist:
    • Develop a thorough production checklist that covers all essential components, configurations, and dependencies required for the network to function properly.
    • Include steps for validating the network’s integrity, security measures, and compatibility with different client implementations.
    • Perform rigorous testing of the production environment to ensure it can handle the anticipated load and stress.

Do you have a validator voting framework and process?
Based on our regular voting meetings with other networks, here’s a concise overview of our experiences in voting framework and process

  1. Proposal Submission: Members of the network community can submit proposals, covering technical upgrades, network parameter changes, or governance rule adjustments.
  2. Proposal Evaluation: Submitted proposals undergo evaluation, involving technical analysis, community discussion, and assessment of their potential impact on the network.
  3. Voting Period: Approved proposals enter a voting period, during which validators cast their votes through on-chain, off-chain, or hybrid mechanisms.
  4. Voting Power: Validators’ voting power is proportional to their stake in the network, granting greater influence to those with larger stakes or higher reputation.
  5. Vote Tallying and Execution: After the voting period, votes are tallied to determine the outcome. Proposals may require a specific threshold of votes to be accepted or rejected. Actions are taken accordingly.
  6. Governance Calls and Discussions: In addition to voting, regular governance calls or meetings enable validators to collectively discuss proposals, express perspectives, and contribute to decision-making.

Are you planning to play any additional roles in the dYdX ecosystem (e.g. market maker, trader, indexer, front-end, other)?

We want to play an indexer if possible, as well as any other roles if needed. We have an extreme strong technical team.

Are there other products or services you want to highlight that could be relevant for dYdX?

We response to any questions and alerts within 30 mins 24/7, and we have a global on-call 24/7 in place.

Any notable contributions in other ecosystems that you would like to highlight for the community?

  1. Educational Content: At Node3, we understand the importance of education in the blockchain space. We plan to leverage our expertise to create educational content on Udemy, TikTok, Youtube and RedBook(A Chinese and Hong Kong popular social media) about dYdX validators, the dYdX ecosystem, the role of node operators. This will help increase understanding and adoption of dYdX’s solution. We successfully promoted this for

  2. Technical Support and Collaboration: We understand that technical issues can be a barrier to adoption for many users. We plan to provide technical support to the dYdX community, helping to resolve issues and improve the user experience. Also, We believe in the power of collaboration. We plan to work closely with other node validators in the dYdX ecosystem, sharing our knowledge and learning from their experiences. We have been providing this for Q and Myria.

  3. Promote client and hardware diversity: We plan to share our technical experience on how to run thousands of nodes in an on-premises setup, as well as how to set up the enterprise level on-premises system. Additionally, we proactively aim to share our experience and promote the diversity. We successfully achieved this for StarkWare DAC.
