Abstract
As edge computing applications in smart healthcare systems are becoming increasingly more popular,
security issues are on the rise as well. Blockchain is emerging as one of the most popular solutions
for securing edge-enabled smart healthcare systems however the extent to which blockchain
has been applied to those systems is unclear. To fill in this gap, we conducted a systematic literature
review focusing on blockchain-based edge-enabled smart healthcare systems. The results of our review
show that this is a novel field as the number of publications seems to grow exponentially each
year. Blockchain is mostly utilized for ensuring access control and data transmission security albeit
several papers emphasize the importance of node security in such systems too. Most edge-enabled
smart healthcare systems support creating and reading data, and approximately half of them support
updating data while deleting is rarely supported.
