Our Journey in Developing Tangled

Inspiration

The inspiration behind this project stemmed from the increasing need for secure and efficient management of electronic health records. With the advent of blockchain technology and decentralized applications and AI, we saw an opportunity to create a system that ensures the integrity, privacy, and accessibility of patient information.

What we Learned

Throughout the development process, We gained invaluable insights into various technologies and concepts:

Blockchain: We delved deep into blockchain technology, learning about smart contracts, transaction management, and decentralized storage.
Decentralized Applications (DApps): Understanding the architecture and functionality of DApps was crucial for designing the user interface and backend systems.
IPFS: Integrating the Inter Planetary File System (IPFS) taught us about decentralized file storage and retrieval, which enhances data resilience.
Directed Acyclic Graph (DAG): Implementing DAG data structures for storing and accessing files efficiently was a challenging yet rewarding endeavor. -Data assistance with AI:Creating a chat bot that can help both the doctor and the patient to customize their format of information analysis with the help of an interactive interface.

Project Development

The project was built iteratively, starting with conceptualization and requirements gathering, followed by prototyping, development, and testing phases. Here's how we approached each stage:

Conceptualization: We outlined the core functionalities of the healthcare data management system, considering user needs, security requirements, and regulatory compliance.
Prototyping: Using wireframing tools, we created mockups of the web application interface and mapped out the data flow and interactions between different components.
Development: We employed a combination of programming languages and frameworks, including Solidity for smart contract development, Next JS framework for the full stack web app, JavaScript for backend development, and IPFS for decentralized file storage.
Testing: Rigorous testing was conducted to ensure the reliability, security, and performance of the system.

Challenges Faced

Building a decentralized healthcare system presented several challenges:

Security: Ensuring data security and privacy in a decentralized environment required robust smart contracts and secure access controls.
Scalability: Designing the system to handle a large volume of data while maintaining performance and scalability was a significant challenge.
Regulatory Compliance: Adhering to healthcare regulations and standards, such as HIPAA in the United States, added complexity to the development process.
User Experience: Balancing security requirements with usability was challenging, as users expect seamless interactions while maintaining data privacy and security. Despite these challenges, overcoming them was a rewarding experience that deepened our understanding of blockchain technology and its applications in healthcare.

What it does

"Tangled," is a decentralized healthcare platform which is AI assisted and designed to securely store and manage patient information using blockchain technology and decentralized applications (DApps). Its core functionalities include uploading patient details, encrypting data, storing files on a decentralized network, verifying user status, and providing AI-driven support.

How we built it

Blockchain Integration: We utilized Ethereum blockchain for smart contract deployment and transaction management.
Decentralized Storage: InterPlanetary File System (IPFS) was employed for decentralized file storage, ensuring data resilience.
Encryption: Data security was ensured through robust cryptographic techniques, including public-key encryption.
Smart Contracts: Solidity was used for developing smart contracts to automate and enforce data management processes.
User Interface: The frontend was built using Next JS framework to provide a user-friendly interface for interacting with the system.
Chat Bot: The chat bot was built using python and integrated using flask to interact with the json data.
Backend: Node.js and Express.js were used to handle server-side logic and API integrations.

Challenges we ran into

Security Concerns: Ensuring data security and privacy in a decentralized environment was a major challenge, requiring thorough encryption and access control mechanisms.
Integration Complexity: Integrating multiple technologies such as blockchain, IPFS, and smart contracts posed integration challenges and required careful coordination.
Scalability: Designing the system to handle a large volume of data while maintaining performance and scalability was challenging.
Regulatory Compliance: Adhering to healthcare regulations and standards, such as HIPAA, added complexity to the development process.
