Hi Thang, sorry for the late reply. Make sure you compiled and deployed your truffle contract under client\src\contracts and the name is the same as the imported one in EthContext.
Hi Jeffrey Yu , I wonder, when the doctor uploads the record file, is there anything to show its immutability. As you know, the purpose of Blockchain is immutable, so when creating a transaction to upload a file, is there a hash or identifier for it. And where is it saved? Can I see them?
The immutability concept in blockchain is to retain an unalterable history of transactions. In the case of this project, the patient can see every edit history made to his or her record. This is implement-able.
