Yes

[GENERAL] If YES, please describe what the dependency is and why you believe it is essential for your project’s delivery. If NO, please write “No dependencies.”

We have a dependency on IOG's Partnerchain SDK which already has a public release. We're planning on supporting the latest released version by the time we start the development process.

[GENERAL] Will your project’s output/s be fully open source?

Yes

[SOLUTION] Please describe your proposed solution

"SuperNode" is the common term used by the industry to describe an infrastructure orchestration layer that unifies the operational aspects of running a diverse set of nodes, processes & services from multiple blockchains.

There are existing implementation within the category of SuperNodes, but none of them focus on the idea of Cardano Partnerchains. Our proposal aims to build a solution tailored for Cardano SPOs where they can leverage their existing knowledge and expertise to increase their revenue stream by offering security to connected Partnerchains.

In particular, our solution will provide the following characteristics / features:

• Partnerchain onboarding wizard: a simple web UI allowing SPOs to execute the required on-chain ceremony to become part of the block-producing committee of a particular partnerchain.
• Partnerchain node provisioning: a simple UI to provision the required infrastructure components (containers) to host the specific node for a partnerchain.
• Unified monitoring: a unified web interface for SPOs to monitor health, load and traffic from all of their connected partnerchains; including alerting system integration.
• Kubernetes: built on top of Kubernetes as a way to leverage it's battle-tested container orchestration functionality and extensive tooling.
• Run it anywhere: our SuperNode is agnostic of the underlying compute infrastructure; it can run on on-premise or on cloud-providers; directly bare metal or in virtualized environments.
• Bring your own cloud: SPOs will be able to easily deploy their SuperNode directly on their own cloud-provider accounts (support for AWS, GCP and Azure) using scripts provided as part of the tool.
• Partnerchain Discovery: the UI will integrate a public catalog of available networks, serving as a marketplace to match SPOs with partnerchains in need of operators.

[IMPACT] Please define the positive impact your project will have on the wider Cardano community

The potential benefits of a rich partnerchain ecosystem on top of Cardano has been extensively discussed by the community, the key points can be summarized as:

• allows new use-cases that require a different set of trade-offs at the protocol level (consensus, finality, etc) by extending Cardano capabilities instead of forcing projects to opt for other chains.
• leverages the extensive and robust community of SPOs to serve as providers for new chains. This provides a new revenue stream for SPOs, effectively making the Cardano network more secure.

All of the above benefits won't live to its potential if the node operators can't handle the complexity of managing all of these new infrastructure requirements and procedures. A SuperNode that simplifies the operation will improve our chances of building a rich and active partnerchain ecosystem.

[CAPABILITY & FEASIBILITY] What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

TxPipe is an active member of the Cardano ecosystem

TxPipe has been developing open-source tools for the Cardano ecosystem for over 3 years and we're not going anywhere. Evidence of our commitment can be found by evaluating the continuous activity of our public code repositories.

Experience developing in the Cardano ecosystem

TxPipe has helped developed several dApps for the Cardano ecosystem. This experience allows us to evaluate the feasibility of the project and its potential benefit from a developer's perspective. We've also participated in development of chains using the released version of the IOG's Partnerchain SDK.

Successful Catalyst proposals

We have successfully completed several Catalyst proposals. This is evidence that our team has the required capabilities to fulfill these type of projects.

Development process will be public and open-source

Both the output and the development process will be public and open-source. This approach provides an easy way for the Catalyst team and the Cardano community to evaluate the progress at each step of the process.
