IEEE/ICACT20210258 Question.3 Questioner: tglee@ptu.ac.kr 2021-02-11 오전 2:55:41	IEEE/ICACT20210258 Answer.3 Answer by Auhor aamir.shahzad@etsmtl.ca 2021-02-11 오전 2:55:41
Thank you for your presentation. This paper proposes blockchain-based blood donation supply chain. According to Fig.1 of the paper, each transaction is gathered to form one supply chain and one supply chain is forming one block, is it correct to understand? If yes, how do you update a transaction when you renew a new transaction on an incomplete block? Does the incomplete block broadcast in blockchain network? If an arbitrary set of transactions is formed as a block instead of that method, how does the logic such as Analysis and Testing update that the corresponding donation has been confirmed to be normal or abnormal?	In this study, when each transaction is initiated and executed (i.e., successfully or non-successfully), the transaction is recorded into the ledger (however, each block has a fixed size).
