Summary: The healthcare industry faces challenges in interoperability due to fragmented communication systems. Blockchain technology is proposed as a governance data management system to optimize information flow between organizations. However, current literature lacks specific application in the healthcare sector. This study contributes to the field by using Hyperledger Fabric to improve information flow and solve fragmentation between two medical institutions. Performance evaluation is conducted using rate controllers on Hyperledger Caliper. This work is valuable for healthcare professionals and academia.

Summary: The article proposes CATP-Fabric, a new blockchain system that addresses the conflicting transaction problem by reducing the number of potentially conflicting transactions and minimizing overhead. CATP-Fabric divides transactions into groups for parallel processing, filters stale transactions, prioritizes read-only transactions, and optimizes the selection of aborting transactions to achieve high throughput with lower aborting transaction rates compared to benchmark systems.
