Thank you for your feedback and for raising these important concerns! To ensure the privacy of medical data stored on the blockchain, MedHub uses encryption. Medical records are encrypted before being stored, and only authorized users (patients and approved doctors) with the correct keys can decrypt and access the data. This guarantees that while the data is immutable on the blockchain, it remains private and inaccessible to unauthorized users. Additionally, we have specific protocols to prevent unauthorized access. The admin of the smart contract is responsible for verifying and approving doctors by reviewing their credentials. Only after a doctor is approved by the admin can they attend to patients and access their data. To further strengthen security, we have implemented role-based access control (RBAC): patients can only access and upload their own data, while doctors can only access the data of patients assigned to them.
Lastly, we apologize for the issue with the project link and are working to resolve it promptly to allow you to try the project soon…here is the updated link https://medhubtron7.netlify.app/....and make sure when you connect you change network to bttc chain

Yes, MedHub incorporates several measures to ensure the confidentiality and integrity of patient information:
Encryption Protocols: Patient data is encrypted before being stored on the blockchain, ensuring that only authorized users with the correct decryption keys (patients and approved doctors) can access it. This keeps sensitive medical records secure and private, even while being stored immutably on the blockchain.
Access Controls: We use role-based access control (RBAC) to regulate access to the system. Only the admin can approve doctors after verifying their credentials, and only approved doctors can access patient records. Patients have full control over their own data and can decide which doctors can view their information.
Regular Audits: While blockchain itself ensures the immutability of data, we plan to implement regular audits to continuously monitor access logs and detect any unauthorized access attempts. Smart contracts can be audited to ensure compliance with security protocols and identify any potential vulnerabilities.
Thanks for the timely response. It clears my curiosity on how the health privacy of the users will be ensured.
But what happens if there is an attempt to breach the system. Are there any measures in place to protect sensitive health information from getting exploited?
I tried again through your updated link and the screenshot attached below is the response I got. I am connected to bttc chain
Tried to sign and I noticed your project demand change of chain to Ethereum via metamask wallet.
Curious if you building on Eth or Tron? Explanation will be better.
Hi, I’m excited to see you building on Tron. The UI looks good, but while testing the app, I noticed that I was connected to the Ethereum network. I would like to understand the reason for this. Also, I’m curious about who holds the encryption keys for the data stored within MedHub.
What practices does MedHub have in place for key generation, storage, rotation, and destruction? Is there a dedicated key management system in use? In the event of a compromise of encryption keys, what immediate actions will MedHub take to protect client data?
Thank you for your feedback and questions! Let me clarify:
I’m actually developing MedHub on the BitTorrent Chain (BTTC). The hackathon hosts pointed out that participants would find the TRON blockchain ideal for building smart contracts or blockchain-related applications, with the additional option of building on BTTC.
At this stage, we have not yet implemented any specific key generation algorithm. However, we securely store our users’ files in Pinata Cloud, which integrates with IPFS for decentralized storage. Additionally, our smart contracts store other user-related information on the blockchain.
We’ve designed the smart contract with a focus on high-security measures through role-based access control. This ensures that the Admin, Doctor, and Patient each have distinct roles:
The Admin manages the entire system, approving doctors and controlling user access.
The Patient has full control over their data and can decide who they want to share it with, ensuring privacy and patient-centered ownership of medical records.
The Doctor can only access patient data if the patient grants permission and after being approved by the Admin.
This approach ensures a high level of security and data ownership within MedHub.
These are great questions regarding trust and verification in the context of blockchain in healthcare. Here’s a breakdown:
How does blockchain technology enhance the verification process of medical professionals’ credentials?
Blockchain technology enhances the verification process by providing an immutable, time-stamped ledger where medical professionals’ credentials can be securely stored. Once credentials are verified and recorded on the blockchain, they cannot be altered or tampered with, ensuring the accuracy and authenticity of the data. This allows hospitals and other healthcare providers to easily access verified, real-time information about a professional’s qualifications without relying on manual verification processes that are often slow and prone to errors.
In what ways does increased transparency from blockchain impact trust among patients and healthcare providers?
Increased transparency provided by blockchain fosters greater trust between patients and healthcare providers. Patients can be assured that their healthcare providers are qualified and verified through a secure, immutable process. Providers can trust that the data they’re accessing is accurate and current. Transparency also ensures accountability, as any changes or actions taken on the blockchain are traceable. This mutual trust helps improve communication and strengthens the overall patient-provider relationship.
What challenges might arise when implementing blockchain for credential verification in healthcare?
Several challenges could arise, including:
Data Privacy Concerns: Handling sensitive information like medical credentials must comply with healthcare regulations (e.g., HIPAA in the U.S.), and blockchain’s immutability can sometimes conflict with regulations that allow for data deletion or alteration.
Interoperability: Ensuring that blockchain-based credential systems can integrate with existing healthcare systems and databases could be a hurdle.
Adoption Resistance: Healthcare providers may be slow to adopt blockchain technology due to unfamiliarity, costs of implementation, or concerns about integrating it with current workflows.
Scalability: As more users and data enter the blockchain, ensuring that the network can handle large volumes of transactions efficiently is a significant challenge.
How can blockchain help prevent fraud in the verification of medical professionals?
Blockchain can help prevent fraud by making credential records tamper-proof. Since credentials are recorded immutably, fraudulent modifications or the creation of false credentials are not possible. Additionally, any attempt to manipulate or fake credentials would be easily detectable, as all changes are traceable on the blockchain, making it harder for bad actors to introduce fraudulent information into the system.
What role do regulatory bodies play in the adoption of blockchain for credential verification?
Regulatory bodies play a key role in setting the standards and guidelines for adopting blockchain in healthcare. They would need to establish the rules for how credentials should be recorded, verified, and managed on the blockchain, ensuring the process complies with legal and privacy requirements. Regulatory bodies can also help in driving adoption, ensuring that blockchain-based credential verification aligns with healthcare regulations, such as data privacy laws, compliance standards, and medical board requirements. Their support is crucial to fostering trust and ensuring that blockchain can be seamlessly integrated into the healthcare sector.
Given MedHub decentralized nature and reliance on blockchain tech, how does the dApp address potential privacy concerns and also ensure the security of patient data.
