Yes

[GENERAL] Please provide here more information on the open source status of your project outputs

Apache 2.0 for the proof-of-concept source code.

Creative Commons for the research report and design documentation.

All project deliverables will be made available in a public Github repository.

[SOLUTION] Please describe your proposed solution

This is a research and development project that will produce: 

• An analysis report that evaluates Cardano-native L2 tools as well as generic Web3 L2 protocols that are candidates for integration with Cardano applications..
• An opinionated architecture design that selects specific protocols and tools to implement as a consensus logic mechanism in the Orcfax validator network. This will include use case descriptions and architecture diagrams. The design will be applicable to other Cardano projects analyzing the implementation of their own Layer2 solutions.
• Proof-of-concept software with a test case suite that demonstrates how a validator node operator can receive external source data, apply validation logic and compare results with other nodes in the L2 network to arrive at consensus on datum value.

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

This project will report on current L2 consensus protocols within Cardano and the Web3 space in general. It will map out a best practice architecture design and provide a demonstration of how the Cardano-native Orcfax project can implement it. The resulting design documentation and proof-of-concept software will be open-sourced and shared with the Cardano community, This will inform and inspire further developments and implementation of L2 consensus protocols across projects in the Cardano 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?

For the past two years the Orcfax team has been researching and developing a comprehensive solution to the oracle problem for Cardano-native dApps and smart contracts. We have developed an open oracle publishing protocol and have been using it to publish an ADA/USD price feed to Cardano Mainnet since early 2024.

We have an active Discord and Twitter community where our ideas, requirements and deployment progress are scrutinized and debated. We participate widely in conferences such as Cardano Summit and Rare Evo to raise awareness about our mission and product offering.

We expect to discuss and share the findings and deliverables of this project in the same community-driven way to ensure trust and accountability.

[BUDGET & COSTS] Please provide a cost breakdown of the proposed work and resources

To accommodate for the fluctuation in ADA price, which creates a conversion risk and a potential budget shortfall, we used the 12 month historical low of $0.25 in October 2023 to establish a budget base price of $0.35 ADA for calculating our expenses.

We will employ 2 software engineers ($100/hr = 285 ADA/hr) and 2 system analysts ($75/hr = 215 ADA/hr) to complete this work over a three month period. The systems analyst role includes requirements analysis, documentation, user acceptance testing, reporting and community management.

Milestone 1 (30 days): ₳32,875

Software Engineer: 55 x hrs x ₳285 = ₳15,675

Systems Analyst: 80 x hrs x ₳215 = ₳17,200

Milestone 2 (30 days): ₳27,500

Software Engineer: 55 x hrs x ₳285 = ₳15,675

Systems Analyst: 55 x hrs x ₳215 = ₳11,825

Milestone 3 (30 days): ₳36,000

Software Engineer: 115 hrs x ₳285 = ₳32,775

Systems Analyst: 15 x hrs x ₳215 = ₳3,225

Milestone 4 (10 days): n/a

[VALUE FOR MONEY] How does the cost of the project represent value for money for the Cardano ecosystem?

Given how important high-performance L2 consensus layers are to the future success of Cardano DeFi business models, the budget for this project represents a small cost for significant ecosystem-wide value. The research report, architecture design, and proof-of-concept software will save time and money for the many other projects in the Cardano space that we know are assessing the same consensus and performance requirements for their own L2 networks. Our work will allow other Cardano projects to confidently steer a path to their own L2 consensus layer solutions and kick-start their own development initiatives.
