Blockchain is a distributed ledger technology whereby transactions are bundled into blocks that are chained together
cryptographically by hash pointers. Blockchain solutions add trust and privacy to the existing internet due to its
tampering resistance and advanced cryptography characteristics. In healthcare systems, the technology has been
implemented to ensure transparency, auditability, interoperability, and proper governance and management of patient
information. This study evaluates blockchain based healthcare systems. Three most common systems were chosen from
public, private/consortium blockchains. The evaluation was done using framework for performance monitoring for
blockchain systems. To describe resource usage, we used five performance evaluation metrics i.e. memory consumption,
disk write and read performance, network data utilization, transaction execution per unit time, and central processing
unit (CPU) usage. The study revealed that the system developed using consortium-based platform outperformed private
and public blockchain for more transactions per unit time, and proper utilization of resources of connected nodes such as
CPU, Memory, and Disk storage. |
