DOCHUB

inspiration

my inspiration for my dochub project was an incident that took place in my college recently when my faculty ask us to complete the certification of an online course and submit he certificate but in this almost 70% of students have submitted the edited certificate from those who have completed the certification😂 so as a solution for this i started research and i came to know that blockchain could solve this issue so i created dochub- a blockchain based certificate generation and validation system . which does not question whether the certificate is authentic or not but it guarantees that the certificates is 100% authentic . ---Forgery is a global issue and Dochub is the solution by cutting the mediators

What it does

Secure Document Verification: Dochub ensures the security and integrity of documents by utilizing Blockchain technology. The hash of each document is stored in the Blockchain, making it tamper-proof and verifiable.

Decentralized System: The system operates without a central authority, eliminating single points of failure. This decentralized approach enhances resilience and ensures that the verification process is not dependent on a single entity.

Fast and Easy Verification: Document verification is a quick and straightforward process with Dochub. There's no need for intermediaries or third-party services, making the verification process efficient and direct.

User-Friendly Interface: Dochub provides a user-friendly interface for both document upload and verification. Users can easily navigate the system to upload documents securely or verify the authenticity of documents.

Support for Multiple Document Types: Dochub is designed to accommodate various document types and formats, making it versatile and suitable for a wide range of use cases.

How we built it

HTML, CSS, Bootstrap, jQuery:

HTML: Provided the structure and markup for the web application. CSS: Styled and customized the appearance of the application for a user-friendly interface. Bootstrap: Used for responsive design and pre-built UI components. jQuery: Simplified DOM manipulation and interaction with user events. JavaScript:

Utilized JavaScript for client-side scripting, enhancing the interactivity and dynamic features of Dochub. Solidity:

Employed Solidity, a programming language for writing smart contracts, to implement the logic for document verification on the Ethereum Blockchain. Metamask and Web3.js:

Integrated Metamask, a cryptocurrency wallet, for users to interact with Ethereum-based smart contracts securely. Used Web3.js to connect the front-end with the Ethereum Blockchain, enabling communication with smart contracts. IPFS.js:

Leveraged IPFS.js to interact with the InterPlanetary File System (IPFS) for secure and decentralized storage of documents. AOS (Animate On Scroll) and PureCounter:

Incorporated AOS for smooth animations during scrolling, enhancing the user experience. Utilized PureCounter for animated counters, providing dynamic visual elements. IPFS :

Implemented IPFS for storing and retrieving documents in a decentralized manner.

Polygon Blockchain (Matic):

Integrated with the Polygon (previously Matic) Blockchain for scalability and cost-efficiency in transaction processing.

Challenges we ran into

Smart Contract Development and Testing:

Challenge: Developing and testing Solidity smart contracts for Ethereum posed challenges, especially with regard to handling various document formats and types. Solution: Conducted thorough testing on Ethereum test networks (Ganache) to identify and address issues in smart contract functionality. Scalability and Gas Costs on Ethereum:

Challenge: Dealing with scalability issues and high gas costs on the Ethereum network. Solution: Explored integration with the Polygon (previously Matic) Blockchain to mitigate scalability concerns and reduce transaction costs. User-Friendly Interface with Blockchain Interaction:

Challenge: Balancing a user-friendly interface with the complexities of interacting with Blockchain technology (Metamask and Web3.js). Solution: Invested in clear user guidance and feedback, providing informative messages and instructions to guide users through interactions with Blockchain components.

Accomplishments that we're proud of

Development of robust encryption algorithms ensuring the highest level of document security during storage and verification and also Achieving the user-friendly interface while seamlessly incorporating interactions with Blockchain components like Metamask and Web3.js.

What we learned

Embarking on Dochub as a solo project, I learned a bunch! First off, I figured out how to blend cool tech stuff like Ethereum Blockchain and IPFS to make sure documents stay super safe. Mastering Solidity for smart contracts was a bit like learning magic spells for the Blockchain world. I also made sure our system encrypts documents like a secret agent and plays nice with everyday users by having a simple interface. Dealing with tech challenges, I teamed up with Polygon (Matic) Blockchain to make things smoother. Testing IPFS was like trying out a new game – making sure everything uploads and checks out properly. Through it all, I learned about keeping things in sync, helping users get the hang of things, and how to make Dochub a tech-savvy, one-person success story!

What's next for DOCHUB

Exciting things are in store for Dochub! Our next steps involve enhancing the platform with new features to elevate your document verification experience. One upcoming feature is the implementation of QR codes, making the verification process even more seamless. Users will be able to scan QR codes to quickly access and verify documents. Additionally, we're exploring the integration of digital watermarks for an extra layer of security. This feature will add a unique identifier to each document, acting like a personalized seal to further safeguard against tampering. Stay tuned as Dochub continues to evolve, bringing you innovative functionalities and heightened security for all your document verification needs!
