Democracy and trust in electoral processes are fundamental to the stability and prosperity of any society [1]. Transparent, secure, and equitable voting systems are at the heart of this democratic ethos. Traditional voting methods have their limitations, including the potential for tampering, scalability issues, and concerns related to transparency [2]. Recent developments in blockchain technology have presented promising solutions to address these challenges [2].
This paper presents a pioneering approach by leveraging blockchain technology, specifically the Internet Computer Protocol (ICP) blockchain, to revolutionize student voting systems. By adopting a decentralized Web3 approach, our proposed e-voting system offers unprecedented transparency, security, and scalability. It offers the potential to create transparent, secure, and tamper-resistant voting processes [2]. However, while blockchain-based e-voting systems have shown immense potential, they have also faced their share of criticisms and challenges [2].
At the national level, implementing blockchain-based voting systems, with their inherent complexities and scalability concerns, remains a formidable task [3]. The scale of such elections, coupled with the significance of their outcomes, makes them vulnerable to interference and security risks. While the adoption of e-voting in universities has shown promising results in terms of increased voter turnout and efficiency [4], university-level elections can also benefit from more reliable and secure e-voting systems [4].
The primary goal of this paper is to introduce a novel approach to student voting, with a specific focus on the university level. Our aim is to address the challenges associated with traditional voting methods by proposing an innovative e-voting system tailored for student elections. Leveraging the power of blockchain technology, specifically the Internet Computer Protocol (ICP) blockchain, and adopting a decentralized Web3 approach, we propose an innovative and secure e-voting system tailored for the unique needs of student elections. In this context, we aim to draw upon the valuable insights from two key papers in the field.
Our paper introduces a decentralized application built on the ICP blockchain, known as the Student Voting system. This system is designed to ensure transparency and anonymity for student voters and consists of two essential stages: the voting process itself and the subsequent validation. This approach aligns with the evolving landscape of e-voting technologies, offering increased security and efficiency. By utilizing blockchain tables and a centralized database, our solution eliminates the need for complex consensus algorithms, enhancing practicality while maintaining privacy and security.
The proposed architecture emphasizes separation of layers and roles to prevent any undue influence on the voting process. A unique hash ensures the anonymity of voters while guaranteeing the integrity of the vote, with no link between voters and their choices stored in the ICP Canisters. With this approach, we uphold the principles of transparency and auditability, free from hidden components or potential fraud.
We aim to contribute to the ongoing evolution of e-voting systems, particularly in university contexts. This paper outlines the development of a practical and secure e-voting solution for students, taking advantage of blockchain technology and the decentralized Web3 approach to provide a trustworthy and efficient platform for university-level elections.
Numerous studies and initiatives have explored the integration of blockchain technology into voting systems to address the challenges inherent in traditional voting methods. In this section, we review notable research efforts in this field and emphasize their contributions.
Oprea et al. [1] introduced a digital voting system leveraging blockchain technology for implementation in technologically advanced environments. While their system assumed the trustworthiness of external entities, it acknowledged the security vulnerabilities associated with this approach. The practical implication of this finding is the recognition of the importance of implementing stringent authentication and authorization protocols to safeguard the integrity of voting systems against external threats.

While various studies have explored the integration of blockchain technology into voting systems, there are distinct gaps in the existing literature that your paper aims to address. Notably, the majority of previous research, suggested a conceptual architecture for e-voting at the university level was presented, but it primarily relied on a centralized database for vote storage and management. While this approach may work in certain scenarios, it falls short of leveraging the full potential of blockchain technology, particularly in the context of voting systems.
In contrast, our paper offers a decentralized approach that leverages the Internet Computer Protocol (ICP) blockchain. The decentralized nature of the ICP blockchain brings significant advantages to the forefront. By deploying our project within the ICP blockchain, our Decentralized Application (Dapp) runs in a canister, accessible through HTTP requests and responses. This eliminates the need for a centralized authority or intermediary entities that are traditionally involved in blockchain voting systems.
One of the key contributions of our paper is the removal of intermediaries in the practical implementation of the voting system. By utilizing the ICP blockchain, we establish a trustless environment where votes are securely recorded and counted without the need for trust in external entities, as opposed to systems relying on centralized databases. This not only enhances transparency but also minimizes the risk of manipulation, as the immutability of the blockchain ensures the integrity of the voting process. Moreover, a comparative analysis highlights that while centralized databases introduce vulnerabilities and limitations in digital voting systems, our decentralized approach offers inherent advantages in terms of security, transparency, and scalability.
Furthermore, while previous research, including the study of Oprea et al. [1], encountered challenges in terms of scalability and voter privacy, our proposed system addresses these concerns. Recent studies have highlighted the limitations of traditional blockchain-based voting systems in managing large-scale elections and ensuring voter privacy. The ICP blockchain's built-in consensus mechanism and cryptographic hashing optimize latency, ensuring efficient management of a large number of voters. The blockchain's decentralization and immutability strengthen user trust, addressing the limitations found in centralized databases.
In summary, the existing literature primarily relies on centralized databases, introducing vulnerabilities and limitations in digital voting systems. Our paper bridges this gap by offering a decentralized approach that leverages the ICP blockchain, eliminating intermediaries and enhancing the security, transparency, and scalability of the voting process. This contribution represents a significant step forward in the field of blockchain-based voting systems.
The proposed system aims to revolutionize the conventional voting methods by harnessing the exceptional capabilities of the Internet Computer Protocol (ICP) blockchain. It utilizes the decentralized nature and immutability of the ICP blockchain to establish a secure, efficient, and transparent voting process. This blockchain-based voting system is designed to overcome the critical challenges associated with traditional voting systems, ensuring a resilient and trustworthy electoral process.
4.1 Voting system architecture
The architecture of our innovative voting system begins with a user-friendly interface developed using React Admin. Students can effortlessly log in to the system, facilitating a seamless and intuitive voting experience. What sets our system apart is the robust security measures implemented for user verification. Each user is verified using SHA-256 cryptography, ensuring the integrity of their identity and preventing unauthorized access. This cryptographic layer adds an extra dimension of security, crucial for maintaining the trust and integrity of the voting process.
Once verified, students gain access to the Decentralized Application (Dapp) hosted on the Internet Computer Protocol (ICP) blockchain's canister. This Dapp is the core component of our system, facilitating the entire voting process through HTTP requests and responses. By harnessing the power of the ICP blockchain, updates and data are securely stored across distributed canisters, ensuring both the integrity and availability of critical information. An essential element of our architecture is the use of the Motoko programming language, the built-in language for ICP's smart contract development. The adoption of Motoko streamlines the creation of secure and efficient smart contracts, ensuring the precise recording and tallying of votes, thus cementing the reliability of our voting system.
This architecture combines user-friendly interfaces, strong cryptography, blockchain technology, and smart contract development, creating a comprehensive and trustworthy voting system for students. The architecture of the student voting can be seen in Figure 1.
Figure 1. Student voting system architecture
4.2 Workflow of the proposed model
4.2.1 Decision proposal
The administrative staff (Admin) proposes decisions with a set of voting options.
4.2.2 Voting process
Students actively participate by casting their votes on the available decisions.
To cast a vote, students should have a minimum number of tokens in their account.
When a student casts a vote, a constant amount of tokens are deducted from their account.
The system ensures that students cannot vote again for the same decision.
4.2.3 Vote counting
The Admin can access the system to view the number of votes cast for each option within a specific decision.
The voting system keeps a tally of the votes for each option.
4.2.4 Decision making
When the voting period concludes or at the discretion of the Admin, the system determines the option with the majority of votes for each decision.
The option with the most votes is declared the winner.
After a decision is made, the voting data for that particular decision can be cleared from memory.
4.3 System advantages
Our proposed system stands out by capitalizing on the immutability of blockchain technology. This makes the entire voting process resistant to tampering and secure against any single point of failure. Notable advantages of the proposed system include:
- Transparency: Every transaction is recorded and accessible on the blockchain, providing voters with a transparent view of the voting process.
- Security: Through cryptographic hashing, secure networks, and robust consensus algorithms, the system minimizes the risk of intrusion.
- Efficiency: The flexibility of consensus algorithms and smart contracts optimize the system's efficiency, ensuring that votes are counted accurately and in a timely manner.
- Accessibility: Voters can participate from anywhere in the world, and the system maintains the integrity of their votes.
- Trust: By enhancing voter trust through end-to-end verification, our system ensures that voters have confidence in the voting process.
Our proposed system offers a comprehensive solution to the challenges faced by traditional and digital voting systems. It combines the benefits of blockchain technology with a flexible and adaptable architecture to create a highly secure, efficient, and transparent voting management system.
5.1 Internet computer protocol blockchain
The Internet Computer Protocol (ICP) functions as a communication protocol employed for the transmission of data across the internet. This reliable and connection-oriented protocol enables applications to initiate, sustain, and conclude connections between devices. ICP is integral to the functioning of the Internet Computer blockchain network, providing the underlying communication infrastructure.

Although frequently utilized in cryptocurrencies like Bitcoin, Blockchain finds application in diverse sectors such as supply chain management and voting systems. While there are certain parallels between them, these technologies diverge in their intended functions and operational mechanisms. These technologies work in tandem, with ICP enabling efficient data transmission and Blockchain ensuring secure and transparent transaction recording.
5.2 Motoko programming language
The Motoko programming language emerges as a contemporary and type-safe language tailored for developers aspiring to construct the forthcoming wave of distributed applications intended for execution on the Internet Computer blockchain network. Specifically crafted to accommodate the distinctive attributes of the Internet Computer, Motoko furnishes a programming environment that is both familiar and resilient. In its capacity as a nascent language, Motoko undergoes continual refinement, incorporating support for novel features and various enhancements. While other languages like Rust and JavaScript could have been used, Motoko was chosen for its seamless integration with the Internet Computer’s architecture and its ability to handle the unique demands of distributed computing.
5.3 ReactJS
ReactJS stands as a JavaScript library dedicated to constructing user interfaces. Originating from the labs of Facebook, it currently undergoes joint stewardship by Facebook itself and a collaborative community comprising individual developers and various companies. This library empowers developers in crafting reusable UI components, thereby simplifying the intricate process of constructing dynamic and interactive web applications. ReactJS was chosen over alternatives like Angular and Vue.js due to its efficient virtual DOM implementation and the flexibility it offers developers in managing application state.
In this section, we present the design and implementation details of our blockchain-based voting system. Our system leverages the Internet Computer Protocol (ICP) blockchain and a React-based frontend to provide a secure and user-friendly voting platform. We describe the algorithms for student creation, casting votes, secure login, and additional critical functionalities. We also discuss how the system handles exceptions or errors and its scalability.
6.1 Algorithms
6.1.1 Student account creation
The student creation algorithm allows eligible students to register for voting. Students are verified against the Canister data (ICP Blockchain decentralized data storage unit) before they can participate in the voting process. In case of exceptions or errors, such as a student trying to register with an already registered StudentID, the system throws an error message and prompts the student to try again with a different ID. The caption of the student voting can be seen in Figure 2.
Figure 2. Caption of student voting
6.1.2 Cast vote
The casting vote algorithm records a student's vote and ensures that they can only vote once. If a student tries to vote more than once, the system throws an error. The process of casting vote can be seen in Figure 3.
Figure 3. Casting vote
6.1.3 Secure login
The secure login algorithm ensures that only authorized users gain access to the system, preventing unauthorized access. If a user enters incorrect login credentials, the system throws an error and prompts the user to try again. The secure login can be seen in Figure 4.
Figure 4. Secure login
6.2 System workflow
6.2.1 User login
- Students register using their StudentID.
- Eligible students are assigned a unique StudentID.
- Student data is stored in the blockchain. The system is designed to handle a large number of student registrations, ensuring scalability. The User login can be seen Figure 5.
Figure 5. User login
6.2.2 Create decision
- Admin proposes a decision and provides options for which students have to participate.
- Decision ID specifies the decision and options for that decision should be entered in Options input, they should be separated using commas. The system can handle multiple decisions and options, demonstrating its scalability. The process of create decision can be seen Figure 6.
Figure 6. Creating decision
6.2.3 Student voting
- Eligible students cast their votes using their StudentID.
- Votes are recorded on the blockchain, ensuring transparency and immutability. The system is capable of recording a large number of votes, further demonstrating its scalability. The Process of Choosing the options can be seen in Figure 7.
Figure 7. Choosing options for a decision
In the performance evaluation of our paper, we employ response time as a crucial evaluation metric for our voting system. Our testing environment simulated a network of 1000 nodes to mimic real-world conditions. To provide a comprehensive assessment, we present two key graphs. The first graph illustrates the response time in relation to the number of queries, ranging from 1 to 1000. This graph vividly demonstrates how our system handles varying levels of user queries, showcasing its responsiveness. The second graph highlights the relationship between the number of updates, i.e., write operations on the blockchain, and the associated response time, also spanning from 1 to 1000. These graphs collectively offer a clear and quantitative representation of our system's performance, emphasizing its efficiency and scalability.
We also tested our system under adverse conditions, such as network outages and data corruption scenarios. Our system demonstrated resilience by recovering and continuing operation without significant impact on response times. The number of updates and time taken seen in Table 1.

Analysis of the performance based on the graph:
1. Incremental Time Increase: As the number of updates increases, we can observe a gradual and incremental increase in the time taken for these updates. This suggests that our DApp's performance remains relatively stable as the update load grows. The increase in processing time is consistent and predictable.
2. Predictable Scalability: The predictable and incremental nature of the time increase indicates that our DApp is scalable. It can accommodate additional updates without experiencing sudden spikes in processing time, which is vital for maintaining a smooth user experience during periods of high activity.
3. Consistency: The performance of our DApp is consistent, which is a positive sign for users. They can expect a uniform experience regardless of the number of updates, as there are no sudden spikes or dips in processing time.
4. Stability: The stable and gradual increase in processing time suggests that our DApp is stable and capable of handling a growing number of updates without causing disruptions.
In summary, this analysis indicates that our DApp exhibits consistent and predictable performance when dealing with various numbers of updates. It demonstrates scalability, maintaining stable processing times as the update load increases. This reliability ensures that users can rely on our DApp for efficient and consistent interactions, which is crucial for the success of a voting application.
