A. Research Gap and Problem Found in Existing System

The research project "NFTCert: Streamlining certificate creation and verification using blockchain and NFT" addresses a significant gap in the existing body of research on certificate verification and authentication. Many of the existing systems, as highlighted in the provided research papers, face several common challenges. Firstly, the traditional paper-based certificate systems lack transparency and are susceptible to forgery, posing a significant security risk. These systems often rely on third-party verification services, introducing cost and complexity into the process. Furthermore, they do not fully harness the benefits of blockchain technology, resulting in inefficiencies, and are often plagued by coordination issues among stakeholders. On the other hand, the projects and systems mentioned primarily focus on specific applications or use cases of blockchain and NFT technology, leaving a gap in offering a comprehensive, user-friendly, and affordable solution for certificate management across diverse industries. NFTCert seeks to bridge this gap by providing a versatile, end-to-end system that allows organizations to create, verify, and store certificates on the Polygon blockchain, eliminating the need for costly third-party services and enhancing transparency, security, and efficiency. NFTCert's emphasis on real-world usability and potential to revolutionize the certificate management process sets it apart from the existing literature, which often remains theoretical or lacks a holistic solution for certificate management challenges.

III. EXISTING SYSTEM

Existing certificate management systems often face several challenges when it comes to generating, storing, and verifying certificates. Traditional paper-based systems are often cumbersome and vulnerable to fraud, as certificates can be easily forged or tampered with. Many digital systems are not much better, lacking transparency and security. These systems typically store certificate data in centralized databases, which can be susceptible to data breaches. Verification processes are often manual and time-consuming, relying on third-party verification services.

The lack of a standardized, secure, and user-friendly approach to certificate management can lead to inefficiencies, increased costs, and a lack of trust in the authenticity of certificates.

This is where NFTCert steps in, introducing a revolutionary approach that leverages blockchain and NFT technology to create a secure, efficient, and user-friendly system for generating, storing, and verifying certificates. NFTCert's unique solution addresses these shortcomings by making the entire process transparent, secure, and decentralized, significantly improving the reliability and trustworthiness of certificates.

IV. PROPOSED SYSTEM

In the proposed system, we introduce a comprehensive solution that streamlines the certificate creation and verification processes with a strong focus on security, efficiency, and decentralization. Users initiate the process after login, and from there, two parallel processes ensue.

First, the 'Certificate Creation' process allows users to request certificates, select templates, generate certificates, include metadata, convert them into non-fungible tokens (NFTs), and seamlessly integrate them with the Polygon blockchain. This innovative approach ensures the immutability and traceability of each certificate, preventing unauthorized alterations and fraud. Simultaneously, the 'Certificate Verification' process allows users to request certificate verification. The system checks the certificate identifier, queries the blockchain for verification, and validates the certificate's authenticity, providing prompt and trustworthy results.

However, one of the groundbreaking features of our system lies in its approach to storage. In addition to blockchain integration, we leverage the InterPlanetary File System (IPFS) to securely store certificates.

This decentralization strategy ensures that certificates are not only tamper-proof but also accessible and retrievable from a distributed network, reducing the reliance on centralized storage systems. By combining these elements, our system enhances certificate management, offers robust verification, and contributes to the broader goal of improving trust and efficiency across industries reliant on certificates.

A. Certificate Creation in NFTCert

1. User Request: The process begins when an organization or entity requests the creation of digital certificates for individuals.
2. Template Selection: The NFTCert system allows users to select predefined certificate templates. These templates can be customized to include recipient names, certificate types, and other relevant information.
3. Certificate Generation: The selected template is used to generate digital certificates. Each certificate is assigned a unique identifier, making it distinct from others.
4. Metadata Inclusion: Along with the unique identifier, metadata is added to each certificate. This metadata contains information about the issuer, the recipient, the purpose of the certificate, and additional details.
5. NFT Conversion: Once created, certificates are converted into non-fungible tokens (NFTs) with their associated metadata. These NFTs are unique and secure representations of the certificates.
6. Blockchain Integration: The NFTs, along with their metadata, are integrated into the Polygon blockchain. The Polygon blockchain acts as a secure and efficient platform for NFTs, ensuring their immutability and traceability.

B. Certificate Verification in NFTCert

1. Verification Request: When a certificate needs to be verified, a user or third party enters the unique identifier associated with the certificate into the NFTCert system.
2. Identifier Check: The system checks the provided unique identifier against the Polygon blockchain records. If the identifier is valid and corresponds to a genuine NFT, the process continues.
3. Blockchain Query: The system queries the blockchain to retrieve the associated metadata. This metadata includes information about the certificate, such as the recipient's name, certificate type, and date of issuance.
4. Certificate Validation: The system validates the certificate information retrieved from the blockchain against the details provided during the verification request. If the information matches, the certificate is verified as genuine and unaltered.
5. Verification Result: The system provides a verification result to the user or third party, indicating whether the certificate is valid. If the certificate is verified as valid, it can be immediately accessed, typically for download or viewing.

V. RESULT

Significant progress has been made in the implementation of the NFTCert project, with encouraging results in the areas of authentication and certificate administration. The use of blockchain technology has resulted in a more efficient method of creating and validating certificates. The system's self-generating certificates, which use pre-defined templates and are stored on the blockchain as non-fungible tokens (NFTs), ensure immutability and traceability.

During the initial testing phase of the certification process, improved effectiveness, security, and openness are demonstrated. Notably, the innovative strategy boosts workflow efficiency, reduces fraud, and fosters trust in all industries that rely on certificates. The latter sections of the research paper contain additional information, in-depth analysis, and statistical results. The NFT has arrived in the user's Metamask Wallet.

Result

VI. LIMITATIONS
