Preventing Waiting List Manipulation And Black Marketing of Donated Organs Through Hyperledger Fabric

A novel method to ensure the security of the shared medical data using smart contracts: Organ transplantation sample

“…It was observed in the studies that Ethereum was commonly used, [17][18][19][20] and a few studies are performed on HLF environments. 14,16 There are also studies at the proposed system stage. [20][21][22][23][24] In previous studies, public blockchains were frequently developed in Ethereum, [17][18][19]25 and permissioned blockchains were generally developed in HLF.…”

“…[20][21][22][23][24] In previous studies, public blockchains were frequently developed in Ethereum, [17][18][19]25 and permissioned blockchains were generally developed in HLF. 14,16 For consensus, proof-of-work 19,24 or proof-of-concept 17 or the number of validation 14,16 were used. Furthermore, it was examined that currently there is no study on liver transplantation by using the HLF environment.…”

“…Also, the other elements are chaincode, which is executable logic that creates new facts, an asset that is represented as a collection of key-value pairs in this platform, privacy which is provided by using a channel, peers who have the same copies of ledger, and chaincodes, a consensus which is a full verification cycle. 3,4,[14][15][16] A SC is a computer agreement. It targets to digitally facilitate, validate or implement a contract's negotiation or performance.…”

“…In this study, it is used chaincodes to coordinate protocols in organ/tissue transplantation process. 3,4,[13][14][15][16]…”

Blockchain Technology for Projects: A Multicriteria Decision Matrix

“…Blockchain first emerged as a cryptocurrency transaction ledger and has now found applications in other spheres, including intellectual property and digital identity management (Perera et al, 2020), philanthropy (Lamba et al, 2019), democracy and governance (Diallo et al, 2018), agriculture (Yang et al, 2020), and healthcare (Griggs et al, 2018). Blockchain is also constantly being explored in logistics and supply chain management (Kaijun et al, 2018), built environment provision (Mukne et al, 2019), education and human rights (Turkanovic ́et al, 2018), energy and environment (Pop et al, 2018), and finance (Chen et al, 2017).…”
