Abstract
Due to the rapid change of population structure, leading to lower birth rates and quick aging rates, the demand for blood supply is increasing significantly. In most countries, blood quality and origin are managed by blood management information systems, such as national authorities. Nevertheless, the traditional system has limitations in this field, such as a lack of detailed blood information, making it challenging to manage blood quality, supply, and demand. Hence, to solve these issues, this paper proposes a blockchain-based system called BloodChain, an improved system to support blood information management, providing more detailed information about blood, such as blood consumption and disposal. BloodChain exploits private blockchain techniques with a limited number of relatively fast and reliable participants, making them suitable for B2B (Business to Business) transactions. In this paper, we also develop a proposed system based on the architecture of Hyperledger Fabric. The evaluation of BloodChain is performed in several scenarios to prove our proposed model’s effectiveness.
Highlights
The blockchain provides smart contracts used for generating transactions which are distributed to every peer in the network, where they are immutably recorded on their copy of the ledger
Hyperledger Fabric [25] is an open-source enterprise-grade permission distributed ledger technology (DLT) platform intended for significant business utilization that offers a few essential capacities that separate it from other distributed ledger or blockchain platforms
In 2018, Kumar et al [27] exploited the potential apps of blockchain technology in current healthcare systems to positively address the trustless and transparent aspects of such system
Summary
Since Satoshi Nakamoto announced to the world the concept of bitcoin and its applications through the article [1], related blockchain applications began to develop strongly in various fields, such as delivery [2,3], transportation [4,5,6], healthcare [7,8], Internet of Things [9,10], energy [11] and healthcare [12,13]. The traceability and trackability of data to ensure compliance with reliability requirements is exploited in several fields, i.e., in healthcare systems [14] and in aeronautical ones [15]. The process from blood donation to blood transfusion to the patient goes through many stages, such as storage and transportation; the ability to store transaction information quickly is needed, and the information cannot be unaccountably modified. In the process of blood provision with ambiguous information about blood origin and quality, complex storage, and transportation conditions, blockchain technology can create traceability.The patients can access the system and view necessary information on this platform without any privacy violation. Blockchain implements the transparency and privacy of each stakeholder along the blood donation supply chain. The structure is organized as follows: the section of the paper presents the background of the research; Section 3 offers a literature review of relevant issues; the BloodChain overall architecture and implementation are shown in the following two sections; Section 6 describes the framework and benefits of the proposed system via evaluation; Section 7 presents the conclusions and future research opportunities
