# 📌 About Choz
<div id="about-choz" class="section">

Choz ranked 4th in the MINA Prize category at the ETHGlobal Istanbul Hackathon in November 2023. The team, consisting of five members, each one excelling in their fields. Choz, a participant in the Mina Navigators program, is well-versed in Mina blockchain infrastructure and recognized within the Mina ecosystem creating a unique and versatile utility.

## Choz's Adventure 💜

The idea of Choz was inspired by the question: "Where would I like to see Blockchain technology in daily life?" Choz offers a quiz experience with reliable results using blockchain technology. By leveraging Zero-Knowledge technology through o1js and the MINA Protocol, Choz ensures quiz questions and answers remain private and secure.

</div>

# 📌 Proposal Overview
<div id="proposal-overview" class="section">

## Problem:

Current test applications in the Web2 domain fail to instill the trust that comes naturally with decentralized systems. Furthermore, most existing Web3 test platforms fall short in offering the privacy users expect, with additional challenges like being unable to distribute any valuable reward to quiz winners automatically.
Additionally, users may find the processes for onboarding, test generation and participation unnecessarily complex, which can present barriers to wider adoption.

## Solution:

Choz leverages the Mina Protocol to ensure both privacy and verifiability within the Web3 domain. At its core, Choz utilizes a sophisticated stack of zkPrograms and a dedicated Quiz Smart Contract to manage reward distribution. zkPrograms enable private, decentralized computation of winners and scores, ensuring transparency and fairness without exposing sensitive data.
To further enhance efficiency and scalability, Choz integrates zkCloudWorker for cloud-based proving. This allows the platform to offload resource-intensive processes, such as generating proofs and executing transactions, to a secure, high-performance cloud environment. This integration ensures that quizzes are processed publicly, securely, and with significantly reduced latency.
Creating a quiz on Choz is as simple as connecting a crypto wallet. This seamless interaction lowers barriers for users while maintaining a robust security framework. For Web2-oriented features—such as emailing results, generating advanced statistics, and creating dynamic leaderboards—Choz employs a Bun.js backend API. This hybrid architecture offers a unique blend of Web3 innovation and Web2 accessibility, making it an ideal platform for educational, corporate, and community-driven engagement activities.

## Impact:
Users can seamlessly utilize Choz for various purposes, including engagement, competition, quizzes, examinations, or onboarding activities, all while maintaining their privacy through blockchain and Zero-Knowledge technology. With an enhanced user experience meticulously designed by Choz’s UX professionals, participants can enjoy an intuitive and secure interface. Upon successfully completing an activity and achieving the required number of correct answers, users are automatically rewarded via blockchain, ensuring a transparent and efficient process.
As Choz operates on the mainnet, it contributes significantly to the broader Web3 ecosystem by offering a functional and innovative test zkApp. Furthermore, the Mina ecosystem benefits from Choz as a benchmark project, providing a well-documented, comprehensible codebase that serves as a model for future blockchain-based applications.

## Audience:
Choz is a versatile platform that transforms assessments across diverse audiences, from educational institutions to corporate teams, event organizers, and blockchain communities. By leveraging blockchain and zero-knowledge proofs, Choz ensures secure, verifiable, and engaging quizzes for modern education, employee training, and interactive events. Universities and online platforms can enhance academic integrity with private on-chain scores and gamified learning, while companies can use Choz for onboarding, team-building, and skill assessments. Event organizers and blockchain ecosystems benefit from its privacy-focused tools for hackathons and workshops, while HR teams can create engaging quizzes to foster culture and knowledge-sharing. With an intuitive design and applications in areas like recruitment, psychological diagnostics, and entertainment, Choz offers a user-friendly, decentralized solution for anyone looking to create impactful and reliable assessments followed by a reliable rewarding system.</p>
</div>

# 📌 Architecture & Design

<div id="architecture--design" class="section">
The basic architecture of our project focuses on providing a fast and reliable quiz creation process.

## Detailed Design & Architecture:

### Choz's architectural structure consists of 4 different layers:

## 1. Cloud (zkCloudWorker)

The zkCloudWorker is an innovative solution designed to address the limitations of traditional proving systems in blockchain applications. By offering ultra-fast proving capabilities in the cloud, it eliminates the need for extensive local resources like large proving keys and powerful processors, streamlining the development and execution of zkApps. Key features include robust process isolation, data encryption, and composability, ensuring privacy and efficiency.

Choz, as a blockchain-based quiz platform, is committed to leveraging cutting-edge technologies to enhance user experience and operational efficiency. Integrating zkCloudWorker into Choz not only aligns with this vision but also accelerates our ability to provide secure, efficient, and scalable services for decentralized quizzes and assessments.

### → Efficient Proving:
Traditional zkApps require users to download large proving keys and execute computations locally, which can be resource-intensive and time-consuming. By integrating zkCloudWorker, Choz offloads these computations to the cloud. Users can now generate zk proofs for quizzes and assessments with just an API call to zkCloudWorker, reducing proving times by 5-10x and memory requirements by up to 90%.

## → User Experience:
This integration enables easily deploying quiz contract and seamless participation in quizzes across both web and mobile platforms without requiring advanced hardware or extended setup times. It lowers the technical barriers for users, particularly in the education, entertainment and social networking sectors, ensuring a wider adoption of Choz.
### → Privacy:

zkCloudWorker ensures the encryption of data at all stages, maintaining the confidentiality of user responses and quiz details. Private data will be processed securely on the web using hashing and Merkle Tree calculations, with preprocessed data sent to zkCloudWorker for proof generation.

### → On Cloud

zkCloudWorker explorer enables users to track their proofs and verify the computation on the cloud without needing to trust the backend server on score calculation and winner proving.

## 2. Backend API
Establishing a healthy connection between the user interface and blockchain via the backend server and onboarding web2 users.

It is a service that adopts a user-friendly hybrid model developed to seamlessly integrate Web2 users into the blockchain ecosystem and provides reliable connection with zkCloudWorker.

This model allows traditional web users to benefit from complex blockchain technology without needing to understand it. The advanced backend infrastructure establishes continuous and secure communication with the zkCloudWorker layer, making the users' experience uninterrupted and reliable. The user-friendly interface allows users to interact easily while managing the complexities in the background.

The set of data generated as a result of user interactions coming from the frontend layer, such as "creating a quiz" and "answering questions", is processed appropriately in the backend layer and is also sent to the zkCloudWorker for zero-knowledge proofs. In this way, data that does not require confidentiality but cannot be carried on the blockchain, such as quiz details, are stored in a safe and accessible manner, while highly confidential data such as user answers and user scores are sent securely to the zkCloudWorker layer for processing. At the same time, it is of critical importance in ensuring that the data coming from the zkCloudWorker is transmitted by the user interface and in a way that prioritizes confidentiality. In addition, the reward distribution process for rewarded quizzes is fully automated on the blockchain thanks to zkCloudWorker's fast and secure service. In this way, users can be sure of a fair exam result with zero knowledge proofs and enjoy the safe distribution of the deserved rewards.

This hybrid model prioritizes user experience while encouraging web2 users to use blockchain-based applications. Thus, it appeals to a wide audience by offering both security and ease of use. It simplifies and accelerates the transition from the Web2 world to the blockchain universe, thus supporting the digital transformation process.

## 3. Mina L1 Quiz Smart Contract And ZkPrograms
Settlement for verifying the proof of winners from WinnerProver zkProgram.
From the quiz publish button we trigger a transaction to be signed by quiz creator to deploy the quiz contract and deposit the total reward pool from zkCloudWorker.

Score Calculator ZkProgram gets the user answers and calculates the scores. Proves the score with the result.

Winner Prover collects the winners from scores that are passing the threshold and pushes them into a chain of winners as an indexed merkle map.

Mina zkApp contract, which verifies the Winner Proofs from Winner Prover, proves the quiz results and makes it possible to distribute rewards.
This structure increases the reliability and confidentiality of quiz results and encourages users. This system offers an important innovation in the field of education, with both the effectiveness of the verification process and the rewards that users will receive.

## 4. Frontend
Client side interface with a professional design approach, using power of Next.js.

This interface has been developed with a modern and aesthetic design approach to maximize users' experience. It provides a fast and smooth user experience by taking advantage of the performance and flexibility advantages of Next.js. o1js allows us to establish a reliable and efficient connection with Mina, managing complex operations in the background and making it possible for users to interact with just ease. This integration enables users to benefit from blockchain technologies by offering both security and ease of use.

Currently we are supporting Auro and Pallad Wallets to sign in and participate in quizzes.

Thanks to the Frontend interface, all kinds of user interactions, such as quiz information created by users and answers to quizzes, are prepared to be transmitted to the Backend API and Quiz Worker (zkCloudWorker) for quick processing. In this way, it becomes much easier for users to interact with the seemingly complex quiz creation and answering system within the Choz architecture.

### Resharable Quizzes (for real-time quizzes)

Quizzes can be reshared with the 'Republish' button after they are finished.

<b>Usage scenarios:</b> A quiz is created, then quiz is finished, a leaderboard is created. The quiz owner can then start a challenge of 'Can you get higher than the 1st?' to attract new participants. Or the quiz owner re-runs the same quiz and analyzes the development of the participants based on their previous successes. Or, a quiz was made and a person could not participate in the quiz due to a legitimate excuse. The quiz owner republishes it with new start and end date. And allows the user to re-enter. The usage scenarios of this feature can be adapted to many conditions.

### Real-Time Quizzes (standard version)

Real-Time quizzes, limited only to set start and end dates, like traditional exams the quiz entrance opens at start date and it ends when the time is up. Participants need to finish before it ends.

<b>Usage:</b> Allows participants to compete at the same time. Each participant has a single right to participate and time, just like a traditional exam. They cannot enter the quiz outside of the specified hours.

### Passive-Active Quizzes (Flexible Status Quizzes)

The quiz owner can make the quiz active or passive whenever they want. When it is active, participants can participate and when they do the quiz they are solving will have a duration that starts counting. It provides a more flexible use; it is especially suitable for quizzes that need to be open for a long time or quizzes with unpredictable timing but with a specified duration.

<b>Usage:</b>
1. You are a speaker at a live event and you cannot predict exactly how long the event will last but you have a quiz that needs to be solved under a specified duration, not infinite. In this case you can create your quiz, make it active or deactive anytime. The participants that are still solving the quiz would not be affected from deactivation.
2. You are a recruiter and you will present and measure the same quiz to multiple candidates at different times in a job interview. You can reuse the same quiz in different situations to see the statistics of the participants.

<div class="epic-cards">
<div class="epic-card">
<div class="tags">
<span class="blockchain-tag">Blockchain</span></div>

### Winner Wallet Validation

We already verify winner wallets' receive permissions on the blockchain. That ignores the wallets with wrong permissions to negate the negative side effects. Upon migration to Mainnet, the <code>fundNewAccount</code> method used in Devnet will be removed to prevent activating inactive winner accounts to not pay 1 Mina extra for not activated wallets. Optionally, we can give creators to give enough extra funds to be able to activate the maximum winners number. So 10 winners max will require extra 10 Mina to pay winners wallet account creation fee before sending the reward. Then creator is able to withdraw the left balance after distribution. Additionally when [preconditions](https://www.o1labs.org/blog/zkapps-on-mina-and-o1js#:~:text=more%20in%2Ddepth.-,Preconditions%20on%20Permissions,-We%E2%80%99ll%20need%20to) will be available, We are going to integrate preconditions to make exclusion of winners on-chain.
</div>

<div class="epic-card">
<div class="tags">
<span class="blockchain-tag">Blockchain</span></div>

### Transaction Fee Adjustment

Extra fees will be charged during quiz contract creation to cover:

<code>Reward distribution costs.</code>
<code>zkCloud transaction fees.</code>

This ensures seamless and automated reward processing on Mainnet while maintaining the sustainability of the system.

# 📌 Risks & Mitigations
<div id="risks--mitigations" class="section">

## 1. Potential Issues on Twitter API Health

### ‼️ Risk:

Twitter API has many reports saying that the API has stability issues and there are downtimes.
### ✅ Mitigation:
<strong>Postpone the quizzes:</strong> Postpone and make the quizzes that require twitter integration passive and require the quiz creator to set a new date or make it active again.

## 2. Smart Contract Security Issues
### ‼️ Risk:
Quiz smart contract can have security issues that could disrupt the distribution process.
### ✅ Mitigation:
<strong>Detailed Testing Process:</strong> Perform extensive E2E and Unit testing with edge cases before the mainnet release, ensuring repeated tests on the latest versions.
<strong>Stable Tag:</strong> Ensure to have a stable tagged version.
<p><strong>Audit:</strong> Ask for audit and feedback from experienced developers in the community and from Mina.</p>

## 3. Backend API Downtime

### ‼️ Risk:

Our backend API hosted in AWS can have downtimes due to high traffic and high memory usages.

### ✅ Mitigation:

<strong>AWS Auto Scale:</strong> Using auto scale option can cost more and would still need to put a budget limit but that would ensure the run time of the server to be stable enough.
These strategies will help mitigate potential risks, ensuring a more efficient and secure project development process.
