Centralization was a major roadblock for telemedicine systems until Blockchain integration. Centralized systems, on the other hand, always run the risk of a single point of failure and are extremely vulnerable to external and internal data breaches, jeopardizing system reliability. Blockchain technology currently effectively addresses such critical challenges. To maintain the shared ledger of health records, it uses a distributed architecture. Every node connected to the Blockchain syncs and verifies all of the ledger copies. Among the primary difficulties addressed by Blockchain include tracing pharmaceuticals and drugs across the supply chain, tracking infected patients’ locations, confirming physicians’ credentials, and securing health records. https://blockchain.oodles.io/blog/potential-blockchain-technology-telemedicine/
