The cost has been compiled for deploying smart contracts for healthcare management system. In order to run an operation on the Ethereum blockchain, there is cost known as Gas. All the transactions needs 21,000 gas as the basic need to run the operation. If a user is interacting with Ethereum smart contract, it takes 21,000 of gas with additional gas associated with running of that specific smart contract. For contract deployment to interaction with the different contracts, the gas has been compiled for medical smart contracts. More complex the functions/operations involved in the smart contracts consumes more gas resulting in more fee. As from the feasibility point of view, it is clear from the results that the smart contract deployment cost for healthcare management system is very low. In terms of medical system, this cost is very economical and everyone would like to pay this minor fee to gain control over their EHR and maintain their medical data for life time. Figure 13 shows the cost of deployment of smart contracts for each pharmacy as estimated by our system. Figure 12. Number of IPDC and their transaction across di ff erent departments / speciality. 7.2. Cost Estimation Using Real Data In terms of deploying healthcare blockchain, the cost associated with implementing smart contracts for healthcare needs to be calculated. The ultimate goal is to implement a system that can provide all the advantages of blockchain to a viable medical health system. In Ethereum blockchain, all programmable calculations cost some fees to avoid network abuse and to overcome other computational related issues. Therefore all operations, computations, message calls, smart contract creation / deployment and storage on EVM require gas to perform all these tasks.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
