computation in order to add this transaction to a block. After the successful execution of transactions, a miner can then broadcast the new block into the network. 7. Validating Workflows with Real Healthcare Datasets We used our developed smart contract workflows to estimate the deployment cost using real healthcare datasets. Blockchain transaction details in ethereum can be seen in Figure 10. Description of the datasets is provided in section A. In section B using the real datasets, the deployment cost are estimated and plotted for various factors. 7.1. Dataset Description Datasets are taken from HSE from its different archives () [75]. The Health Service Executive is responsible for providing health and personal social services with public funds for all people living in Ireland. All the outpatients, Inpatients waiting list across different departments/Hospital in Ireland has considered to be used in this work. The Outpatient, Inpatient and Day case waiting lists are managed by (NTPF) the National Treatment Purchase Fund from collection of data to its validation phase. The Waiting List report for OP states the total number of patients who are waiting, across the various time bands, for a first appointment at a consultant-led Outpatient clinic. Every individual report consists of the numbers waiting per Hospital in each Figure 9. Contract surgery. 6. Cost Estimation Method In terms of deploying medical blockchain, there is a need to make estimation of the cost associated with deploying healthcare smart contracts. The ultimate goal is to propose a system which can give a feasible medical health system with all the benefits of blockchain. All programmable calculations in Ethereum blockchian cost some fees to avoid the abuse of network and overcome other computational related issues. The fee in Ethereum blockchain is specified as gas to run all sort of transactions. Gas refers to the payment or price value required for a successful transaction or execution of a contract on the Ethereum blockchain platform. The exact price of gas is determined by the network miners who may refuse to process a transaction if their limit is not met by the gas price. Hence all the operations, computations, message call, creation / deployment of smart contracts and storage on Ethereum vitual machine (EVM) needs gas to perform all these tasks. If someone wants to do any sort of operation on EVM, they must have specific amount of gas in their account to execute transactions on Ethereum virtual machine. There is a gas limit for every transactions, so if there is any unused gas it will return to the user account after the execution of transactions. If a user doesn’t have valid balance account, he can’t carry on any kind of operation and hence considered as invalid transaction. In EVM Ethers are used to purchase gas and the users who are running the transactions can set their account gas limit for the specific transaction. But again it’s on the miner if they tend to approve the transaction or not. If a

    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.
