\begin{abstract}
Blockchain is emerging as a solution to secure healthcare records but
faces certain shortcomings like transaction time, execution time, gas
consumption, etc. The current article designed an extensive
blockchain-based healthcare system (MyEasyHeathcare) with reduced gas
consumption and execution time, along with enhanced security at three
levels. At the first level, the professionals and patients get
registered, which provides identity access management. Secondly,
authorization is required for each registered entity by the owners.
Lastly, the third level includes a doctor-patient relationship where a
specific patient is assigned to a particular doctor by the hospital's
owner. The data is protected from the outer world and is preserved only
between the doctor and the patient. Moreover, to include the majority of
tasks for hospital management, the developed system incorporates a smart
contract to record seven different parameters for patient diagnosis by
physician and fifteen different parameters by a pathologist. The
designed system is evaluated for the amount of gas consumed and
execution cost to decide the usage in the real world; the results
testify the proposed system is useful in the real world.%
