Please describe your proposed solution.

What is Xerberus?:

Xerberus is a Risk Rating Protocol that empowers investors by providing metrics to facilitate a quick and objective assessment of any crypto asset. Our platform, Xerberus V1, is fully functional and will be entirely published by 23.12.2023. Until then, access will remain exclusive to our Xercher Community. We encourage anyone who would like to be granted access to the platform to reach out to us on our socials (Discord, X, etc.).

Our platform allows users to assess the risk associated with any crypto asset and explore the metrics underlying our Risk Ratings. What sets Xerberus apart from any other risk assessment system is its radical approach that relies exclusively on on-chain data. We believe that bad actors can easily fake credentials and use social media to deceive investors, but one thing they cannot do is hide their transaction records.

More concretely, the fundamental idea at the core of Xerberus is that transactions encode relevant information that can be used to guide the actions of rational investors. Because markets are efficient and priced in all available knowledge, we believe that Xerberus empowers its users by decoding this hidden information and making it readable.

Problem: The Risk Ratings offered by Xerberus Ltd. have proven effective in guiding investors, but their computation is centralized at Xerberus servers. This contradicts the decentralized ethos of blockchain technology and creates a vulnerability with a single point of failure by placing the entire system's reliability on Xerberus alone. This setup could lead to potential biases, technical failure, or security issues within the company.

Solution:

1. Decentralising Computation with Xerberus Nodes: To address the centralization concern, Xerberus aims to distribute the computation of its Risk Ratings, increasing its resilience and scaling up its computing power. The node network will form an effective Cardano Partnerchain built on "substrate" and run its own consensus, following a principle that we call "Proof of Useful Work," with risk rating constituting proof of computation.
2. Community Engagement and Governance: Governance is implicit through Xerberus Node Operator's ability to accept or deny updates to their node (which constitutes an effective vote right) and explicit through a governance body formed by Xerberus Community Members.
3. Transparent and Verifiable Computation: The computation subjacent to our risk ratings becomes transparent and verifiable with decentralized and open-sourced nodes. This is a critical step in building the lasting credibility of the Xerberus system, which relies on methodological excellence and verifiability.
4. Downtime Reduction: By employing multiple nodes to form an efficient partner chain that undertakes Proof of Useful Work, we can significantly reduce the risk of computational downtime. This ensures the ultimate risk scoring system's continuous operation and reliability so that third-party users are not impacted.

Impact on Xerberus: The proof of concept is up and running, and given we achieved our publication date of 23.12.2023, we are almost six months ahead of schedule for our last catalyst proposal. However, Xerberus is far from having realized its full potential. Expanding Xerberus to a decentralized network running on Cardano as a partnerchain would take Xerberus to a whole new level: A genuinely decentralized system would put Xerberus into the hands of the community and create a new layer of Cardano itself that can be used by other Dapps that want to build on the Xerberus Risk Engine. From Lending Protocols that wish to manage their Credit Risk to Option Protocols that look to improve their internal pricing engine, they need a risk engine that can be built on Xerberus.

1. Enhanced Trust and Reliability: Decentralization would significantly increase the trust and reliability of the Xerberus risk ratings.
2. Reduced Risk of Manipulation: Distributing computation across various nodes would significantly reduce the risk of manipulation or the introduction of biases by a single entity. As noted, we had risk rating agencies before, and they worked well until they chose to play against the people they were serving, leading to the great financial crisis of 2008.
3. Alignment with Blockchain Principles: True to the principles of blockchain technology, this solution honors decentralization,

Uniqueness of the Solution

1. Leveraging Cardano's Partnerchain: Building a Cardano Partnerchain that encompasses all crypto assets is a pioneering move, pushing the boundaries of blockchain capabilities. The Partnerchain setup using the substrate framework is highly customizable and allows validators from other Layer Ones to run a Xerberus Node on top of their infrastructure. Effectively, that will enable the "Xerberus Chain" to consume data from places like Ethereum, Polkadot, etc., and serve clients there while effectively settling the created value back to the Cardano ecosystem.
2. Community-driven Updates and Innovations: The governance model allows for a democratic and community-driven approach to updating and improving the risk assessment model, ensuring that it evolves with the ecosystem and stays relevant.
3. Decentralized Risk Assessment Model: Unlike traditional centralized Risk Rating models, Xerberus Nodes offer a blockchain-native solution in tune with the decentralized nature of blockchain technology.

Please define the positive impact your project will have on the wider Cardano community.

The Benefits to Cardano

1. Increased safety for the entire Ecosystem: An additional layer of protection to Cardano that helps with the early detection of bad actors and damaging behavior is essential for enhancing trust and confidence among investors. This is especially true in Cardano's DeFi sector, which continues to grow and evolve. Right now, most of DeFi lacks any form of risk management as it is simply not rewarded. However, creating a risk assessment instrument will contribute to and make it easy to understand for end users. We change what is acceptable by creating transparency. The resulting improving financial robustness of the DeFi ecosystem will be a significant stepping stone to Cardano's establishment as a powerhouse in the DeFi ecosystem.
2. Establishing an Equal Playing Field: By providing objective, censorship-resistant risk assessments for all crypto assets, including Layer One blockchains, Xerberus levels the playing field for Cardano to receive a fair evaluation alongside other ecosystems. It also promotes equality by empowering all users with tools that reduce the gap between the more and the less tech-savvy.
3. Driving Revenue and Exposure from External Sources: By providing risk ratings for other Layer Ones, the Xerberus Network attracts revenue from across various ecosystems that flows back into the Cardano economy. Within Cardano, Xerberus Labs LTD generates cash flow by redirecting the revenue generated in the Xerberus Platform to the nodes, as it captivates other Dapps and professional traders using Xerberus' quantitative outputs.
4. Enhancing Cardano's Recognition: The ethics of Xerberus and its data-driven, objective, and unbiased assessments will reflect positively on the Cardano Network and boost its recognition.

Mihir Solankar is a full-time core team member and Xerberus' first employee. He is a skilled back-end developer who has been coding since his early teenage years. He worked in various positions and is a critical asset in developing our platform. (https://github.com/Mi88ir?tab=overview&from=2023-07-01&to=2023-07-11)

While this capable core team is central to the company, Xerberus extends beyond it. We enjoy the privilege of having an outstanding advisory board that includes people with solid institutional backgrounds and occupying influential positions. These individuals possess in-depth knowledge of financial market operations and believe in Xerberus and its capability to achieve its goals. Our first advisor has decades of experience in institutional trading. This individual has built quantitative trading strategies and managed hedge funds in London, New York, and Silicon Valley. This person currently holds a managerial position at the largest data broker in the market. Our second advisor is, among other roles, a former Executive Director of Goldman Sachs New York and currently manages his own proprietary quant crypto trading firm. We are not permitted to publish the full names of our advisors, but we can provide proof of engagement to trusted representatives of the Cardano community under signed NDAs.

Lastly, we are fortunate to have support from a dedicated group of community members and highly skilled freelancers who excel in building large databases and developing machine-learning models. As we continue to grow, we plan on using the funds raised to expand the team and hire two long-time supporters currently employed and waiting for an opportunity to join Xerberus Labs Ltd. full-time. The new team members will be responsible for building the Xerberus Nodes.

Please provide a cost breakdown of the proposed work and resources.

Please find the budget detailed in the spreadsheet provided below: https://docs.google.com/spreadsheets/d/e/2PACX-1vSzotWbRBcsoxp0dYNKU370NGyL0-SjOXYZtgdAEb2YchbVUjyWlm10grAdlCA5EomTjjYK701EU180/pubhtml?gid=0&single=true.

Funds will be used primarily to offset the costs associated with the expansion of expenses of the two talented professionals joining our team to help us build the Xerberus node and deliver our vision: a Blockchain Architect and a Senior Developer. The cost of hiring them both is $224,000 per year, which is an excellent value for money considering the high demand and skill level of these roles. This amount is based on a gross salary of $8,000 per month, which is ca. $5,000 after taxes, and provides good living standards in London. Xerberus will also commit funds to these human resources, complementing their salary with token and equity options as an incentive and a reward for their work.

This proposal totals approximately $225.000, assuming a stable ADA (Cardano) price of $0.30. This price will cover the described project. We acknowledge that the current ADA price is higher and hope it remains stable. Still, we must include a safety margin that covers the impact of market hardships on our employees and their families. In case the ADA price falls to something around $0.25. and the proposal totals approximately $187,500. We will still be able to fill the gap with other funds. If ADA prices strongly increase or decrease, we will scale the project up or down accordingly. However, if we stay within the ranges given above, the project will be executed as described.

Below is a screenshot of the budget:

• The starting balance shown in the spreadsheet originates from our angel investors.
• The revenue streams noted in the spreadsheet are not related to the nodes but come from advisory services provided by Xerberus Labs Ltd.

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

Xerberus’ development relies on various funding streams, including private investment funds, different revenue streams from services we provide to other projects, and Catalyst funding (Fund10).

We offer a critical services to the community while creating a platform that draws investor attention to the Cardano Ecosystem and generating external revenue, Xerberus channels revenue back into the Cardano financial system via an out network of nodes. Additionally, we will be yet another case study community members can point to display the always-evolving strengths of the Cardano Network and set an example for the exploding partner chain ecosystem of Cardano. Our nodes will be open sources and can be a blueprint for future partner chains.

The different layers of value we create ensure an exceptionally high investment return per ADA spent, significantly benefiting the community.
