Abstract
In recent years, several blockchain-based access control models have been emerged to give individuals control over their sensitive Electronic Medical Records (EMRs) in the healthcare sector. From our extensive literature review, we observe that currently, these models have no provision of prioritising the emergency transactions. This critically affects the quick and streamline sharing of EMRs in a multi-domain network environment. Further, it restricts the optimal usage of blockchain network affecting scalability. Sharding has arisen as a viable option for addressing the issue of blockchain’s scalability and performance. Motivated from this, in this paper, we first propose prioritised sharding (P-sharding), a novel mechanism to streamline the processing of priority or emergency transactions in blockchain-based access control models by improving the throughput of each prioritised shard, in the context of multi-domain healthcare networks. Finally, the performance of the model is verified, validated, and also compared with the existing sharding mechanism. The obtained results are promising and encourage to further sparkle this direction.
