Please describe your proposed solution.

The security and integrity of smart contracts in a blockchain ecosystem is paramount. As such, a robust mechanism that ensures only verified human users are interacting with these contracts greatly minimizes the risks associated with bots and other malicious actors. This has given rise to the proposed solution of a Proof-of-Human (PoH) system, specifically designed for smart contracts.

The PoH system begins with a user verification process, aimed at confirming the humanity of a user wishing to interact with a smart contract. The methods employed for this process could range from biometrics, CAPTCHAs or behavioral analysis, depending on the level of security required and the trade-offs in terms of user privacy and system efficiency.

Once the system validates a user's humanity, a cryptographic proof is generated. This proof serves as a digital token of humanity, providing an assurance to the human origin of smart contract interactions. It is critical for this cryptographic proof generation to be secure, robust, and efficient to maintain the system's effectiveness even with high transaction volumes.

A user can demonstrate the humanity of a transaction with this cryptographic proof by attaching it to any transactions initiated by said user. Resulting in every transaction within the system carrying an indelible mark of human interaction, bolstering overall system integrity.

The final step of the PoH system is the validation of the cryptographic proof. Depending on the system's architecture, this validation could be performed either by other network participants or by the smart contract itself. This validation step acts as a necessary step to ensure authenticity and genuinity of the cryptographic proofs attached to transactions.

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

The proposed Proof-of-Human (PoH) system addresses the challenge by ensuring that only verified human users can interact with smart contracts on the Cardano blockchain.

There are several benefits this solution can bring to the Cardano ecosystem:

Enhanced Security: By ensuring only verified humans can interact with smart contracts, the PoH system reduces the risk of fraudulent activities and manipulations that can be carried out by bots or malicious actors. It adds an additional layer of security that can maintain the trust of users in the Cardano network.

Increased Confidence: By implementing this mechanism, the Cardano ecosystem can provide additional reassurances to its users about the authenticity and security of their transactions, increasing user confidence and potentially driving broader adoption of the Cardano blockchain.

Scalability and Decentralization: The proposed solution does not contradict Cardano's principles of scalability and decentralization. While it adds a layer of security, it doesn't require central authorities to verify users, keeping in line with Cardano's commitment to decentralization.

Privacy Preservation: While the PoH system verifies users, it is designed to respect privacy rules and regulations. This is imperative to maintain user trust and uphold the privacy-centric ethos that is a hallmark of Cardano and blockchain technologies in general.

With this proposal, we present a solution for users and developers of smart contract projects, aiming to bolster the security of their contracts, cultivate trust among their user base and enhance business value by ensuring service reliability. This is achieved by providing methods for verifying humanity without compromising a user’s privacy. By implementing this proposal, the ecosystem stands to gain long-term benefits from the improved security, enhanced trustworthiness, and ultimately, sustainable growth from verifiably human-made transactions.

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

Measuring the success of the Proof-of-Human (PoH) system for smart contracts involves both quantitative and qualitative metrics. Here are some key indicators that we could use to assess the project's success:

1. Working Product Proof-of-Human: Above everything the project will be successful by delivering a working product.

The next two things should be by the community to measure to ensure that this system will be used.

1. System Efficiency: Efficiency can be measured in terms of the time it takes for the PoH system to verify a user and attach the cryptographic proof to a transaction. An efficient system would minimize delays, providing a frictionless experience.
2. Privacy Compliance: Ensuring the system respects privacy rules and regulations is critical. Success in this area could be assessed by periodic audits or assessments to ensure compliance with relevant privacy standards and regulations across different jurisdictions.

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

The main goals of the Proof-of-Human (PoH) system for smart contracts are:

1. Enhancing Security: The primary goal is to secure the Cardano ecosystem by ensuring that only verified human users can interact with smart contracts, thereby minimizing fraudulent activities and manipulations by bots or malicious actors.
2. Promoting User Confidence: By providing an additional layer of security, the PoH system aims to increase the confidence of users in the Cardano ecosystem, potentially driving broader adoption.
3. Preserving User Privacy: While implementing the PoH system, a key goal is to respect privacy rules and regulations to ensure users' rights are protected and trust in the system is maintained.

To validate the feasibility of this approach, the following steps will be taken:

Prototype Development: The first step is to develop a prototype of the PoH system. This involves designing and implementing the verification methods, cryptographic proof generation, and validation processes. This prototype serves as a proof-of-concept, demonstrating the system's functional feasibility.

Testing and Iteration: After the prototype is developed, it will undergo rigorous testing. This involves validating the system with different scenarios to ensure that it accurately verifies human users and successfully attaches cryptographic proofs to transactions. Feedback from these tests will be used to refine and improve the system.

Pilot Implementation: Before full-scale deployment, the PoH system will be implemented on a smaller scale or in a controlled environment. This allows for a real-world evaluation of the system's performance and the gathering of user feedback.

Please provide a detailed budget breakdown of the proposed work and resources.

Please note that each line item includes overhead operational, product management & project management costs to coordinate the product development and for filling out forms and reporting milestones to the Project Catalyst F10 teams – due to the friction we experienced the last time we received funding. We used a conversion rate of 0.165 ADA per USD due to the high volatility, plus a detailed analysis of historical price movements show that the low might be in at around 0.20 cents, but there is no support line after that until around 0.13 cents, so we used the average of both.
