Please describe your proposed solution.

Our proposed solution addresses the challenge of efficiently distributing stake pool rewards to multiple pledge/owner wallets while reducing errors. We will deliver a user-friendly Command-Line Interface (CLI) tool that simplifies this process, ensuring ease of use for stake pool operators. By automating reward distribution based on each pledge wallet's stake and other configurable parameters, our tool eliminates the need for manual calculations and transactions, saving significant time and effort.

Furthermore, our solution will provide comprehensive documentation to guide users through installation, configuration, and utilization. This documentation will serve as a valuable resource, further minimizing the risk of errors by providing clear instructions and troubleshooting tips. By streamlining operational processes and reducing the chance of mistakes, our CLI tool enhances the overall efficiency and accuracy of reward distribution among stake pool owners.

By saving time, effort, and reducing errors, our solution empowers stake pool operators to allocate rewards more efficiently and reliably. This not only promotes fair and transparent distribution but also encourages wider participation by reducing barriers to entry for community members with smaller pledge amounts. Our solution plays a pivotal role in fostering decentralization within the Cardano ecosystem while enhancing the overall user experience for stake pool operators.

How does your proposed solution address the challenge and what benefits will this bring to the Cardano ecosystem?

The CLI tool we propose offers numerous benefits, addressing the challenges faced by community members attempting to increase pledge through collaboration among a diverse range of participants. By enabling community members with smaller pledge amounts to join forces and create a pool with high overall pledge, our tool fosters inclusivity and democratization of the Cardano ecosystem. This approach ensures that stake pools are not solely controlled by wealthy individuals or corporations, promoting decentralization and preventing consolidation. The collaborative effort results in higher overall pledge, which in turn increases the pool rewards for all participants. By automating reward distribution based on each pledge wallet's stake, our tool ensures fairness and transparency in the allocation of rewards. It empowers community members, regardless of their individual resources, to actively participate in and benefit from the Cardano blockchain.

How do you intend to measure the success of your project?

Technical success will be achieved when reward payouts for complex owner scenarios may be simply carried out with a CLI call. In addition, the CLI tool will be able to automatically run at each epoch rollover. The project success will be further measured by how many small pools are able to grow pledge through using our solution.

Please describe your plans to share the outputs and results of your project?

We intend to share the tool and its capabilities through Twitter, Medium, YouTube, and Reddit. We plan to develop good documentation and examples (including video) so that users with less technical background will be able to get setup quickly.

What is your capability to deliver your project with high levels of trust and accountability?

The Viper Science team has operated the high performance VIPER stake pools on the Cardano blockchain since 2019 (starting during the incentivized testnet). The team has extensive experience in software development and has successfully delivered on multiple Catalyst proposals.

The Viper Science team has been an active contributor to the Cardano community for over four years. In addition to operating stake pools since the Incentivized Testnet, we have developed several open source tools for Cardano developers and SPOs. Three of these projects have been successfully funded through Catalyst in the past:

• Cardano-Tools Python Library (<https://projectcatalyst.io/funds/8/f8-open-source-development-ecosystem/cardano-tools-python-library>)
• Cardano development library in C++ (<https://projectcatalyst.io/funds/8/f8-open-source-development-ecosystem/cardano-development-library-in-c>)
• API for Multi-Delegation Portfolios (<https://projectcatalyst.io/funds/6/f6-dapps-and-integrations/api-for-multi-delegation-portfolios>)

A complete list of our contributions can be found at <https://viperscience.com/>

What are the main goals for the project and how will you validate if your approach is feasible?

The goal of this project is a simple and easy to use CLI tool for managing reward distribution among collaborative owners of a single stake pool. The approach is feasible since this is how many stake pools currently run (including VIPER stake pool). Many pools have custom tooling in place to manage the complex rewards distribution; however, the simplicity of our proposed design will make it easier for new/smaller operations to combine.

Please provide a detailed breakdown of your project’s milestones and each of the main tasks or activities to reach the milestone plus the expected timeline for the delivery.

We anticipate the timeline for delivery of this project to be 12 to 16 weeks. This estimated timeline accounts for part-time staff allocation and does not represent our estimated labor hours (see budget section for estimated labor).

Milestone 1 - Stake Pool Reward Distribution Calculations [5 weeks, 9130 ADA]

Implement functionality to accurately calculate the staking rewards for each pledge wallet.

1. Access historical pledge wallet balances through multiple APIs. The app will allow users to configure which API service to use for data. [2 weeks]
2. Determine epoch roll overs and total pool rewards for each epoch. Separate staking rewards from pool fees. Split up staking rewards accurately per wallet. This may include techniques to avoid rounding errors. [2 weeks]
3. Further testing of calculations against historical data. [1 week]

Milestone 2 - CLI Application [5 weeks, 9130 ADA]

1. CLI user interface complete with help text. [3 weeks]
2. Configuration file format designed. Any parsing code completed. [2 weeks]

Milestone 3 - Application Testing and Documentation [6 weeks, 18260 ADA]

How does the cost of the project represent value for money for the Cardano ecosystem?

The cost of implementing our proposed solution represents excellent value for money for the Cardano ecosystem. By investing in the development and deployment of the CLI tool, the ecosystem stands to gain significant benefits. The tool streamlines the process of distributing stake pool rewards to multiple pledge/owner wallets, reducing the manual effort required by stake pool operators. This automation not only saves time and effort but also minimizes the risk of errors in reward calculations and transactions. The resulting efficiency and accuracy enhance the overall operational processes of community-run stake pools.

Moreover, the tool fosters wider participation in the Cardano ecosystem by reducing barriers to entry for community members with smaller pledge amounts. It promotes inclusivity and prevents the consolidation of stake pool control into the hands of a few wealthy individuals or corporations. This aspect aligns with Cardano's vision of decentralization and community empowerment.

Considering the long-term benefits that the tool brings to the ecosystem, the cost incurred represents a worthwhile investment. The enhanced efficiency, fairness, and transparency in reward distribution contribute to the overall sustainability and growth of the Cardano ecosystem. The value derived from enabling wider participation, preventing consolidation, and promoting stake pool decentralization makes the cost of the project highly justified in terms of the long-term benefits it provides to the Cardano community and ecosystem as a whole.
