As the need for Blood grows, effective administration and tracking systems for blood donations are becoming increasingly important. To improve the blood donation process’s efficiency, transparency, and safety, this paper suggests a new system that utilizes blockchain technology and the Internet of Things (IoT). Integrity and safety of the blood supply may be guaranteed thanks to the combination of blockchain and IoT, which permits real-time monitoring of storage conditions and instant warning of any deviations. Storage limitations are addressed via the Interplanetary File System (IPFS), and the Ethereum blockchain is used for decentralized, transparent, and traceable management of blood donation operations. Both security evaluations and comparisons with existing solutions have confirmed the efficacy of the suggested blockchain-based system. The system’s adaptability to certain industries is made possible by its generalizability. Through smart contracts, blockchain technology ensures identity verification of donors, supply chain management, consent management, traceability, and automation. With IoT sensors, environmental factors like temperature, humidity, and alarms can be tracked in real-time, allowing constant quality control. Transparency, accessibility, and safety in blood donation processes are all improved by the IPFS-based system. More study is needed to determine whether these methods can be implemented in the real world. The proposed system would completely restructure how blood donations are handled, replacing them with a decentralized, trackable, and secure Network.

Due to the shortage of available kidney organs for transplants, handling every donor kidney with utmost care is crucial to preserve the organ's health, especially during the organ supply chain where kidneys are prone to deterioration during transportation. Therefore, this research proposes a blockchain platform to aid in managing kidneys in the supply chain. This framework establishes a secure system that meticulously tracks the organ's location and handling, safeguarding the health from donor to recipient. Additionally, a machine-learning algorithm is embedded to monitor organ health in real-time against various metrics for prompt detection of possible kidney damage.

Blockchain is a disruptive technology and incredibly popular nowadays based on decentralized ledger technology. It is a tampered-proof technology that saves the transaction data permanently in a distributed ledger with an immutable time-stamped series record of data, and it is built on the idea of a peer-to-peer network. Blockchain efficiently creates trust between people and machines. It provides new approaches and solutions that cater to the business demands oriented to the fourth industrial revolution. Healthcare is one of the key research use case of blockchain wherein health records are required to be electronic for e-governance. In this paper, we propose the blockchain based Vaccine Intelligent Network for pregnant women, included vaccines covered under the Universal Immunization Program. Our solution is based on the Hyperledger Fabric framework to develop the Electronic Immunization Record of vaccinated pregnant women. The proposed system transforms the immunization record from paper to a reliable digital platforms that will benefit all nation citizens and further reduce anomalies.

The escalating demand for blood and its derivatives in the medical field underpins its indispensable nature for disease diagnosis and therapy. Such essential life-giving components are irreplaceable, necessitating a continuous reliance on voluntary blood donors. Existing methodologies primarily address the challenges of blood storage and its logistical distribution among healthcare centers. These conventional strategies lean towards centralized systems, often compromising data transparency and accessibility. Notably, there remains a significant gap in incentivizing and raising awareness among potential and existing donors regarding the life-saving act of blood donation. Recognizing these challenges, we introduce a robust and innovative framework that harnesses the potential of Blockchain technology, coupled with the power of smart contracts. Furthermore, to foster a sustainable blood donation ecosystem, we advocate the shift from traditional paper-based recognition to digitized donor acknowledgment using Non-Fungible Tokens (NFTs). Our novel approach encapsulates four key areas: (a) Introduction of a supply chain oversight mechanism for blood and its derivatives through Blockchain and smart contracts; (b) Development of a digital certification system for blood donors utilizing NFTs; (c) Execution of our suggested framework via smart contracts, offering a tangible proof-of-concept; and (d) Assessment and implementation of the proof-of-concept across four prominent platforms: ERC721 (ETH’s NFT), and the Ethereum Virtual Machine (EVM) employing the Solidity language – this encompasses the BNB Smart Chain, Fantom, Polygon, and Celo, aiming to discern the optimal platform compatible with our innovative framework.

In Malaysia, private healthcare providers keep computerized records of vaccination data, including personal information, diagnostic results, and vaccine prescriptions. However, such sensitive information is commonly stored using a centralized storage paradigm which subsequently brings about the issue of maintaining user privacy. Concerning this, unauthorized access to crucial information such as identity details and ailments that a patient is suffering from, as well as the misuse of patients' data and medical reports, are common threats to user's (patient) privacy. To overcome this problem, the researchers suggest leveraging IPFS (Interplanetary File System) and blockchain technology to create a decentralized children's immunization record management system. While respecting patient privacy, the proposed system also allows authorized entities, such as healthcare professionals, and provides easy access to medical data (e.g., doctors and nurses). The proposed decentralized system integrates IPFS, blockchain, and AES cryptography to ensure consistency, integrity, and accessibility. A permission Ethereum blockchain allows hospitals and patients within private healthcare providers to connect. We utilized a combination of symmetric and asymmetric key encryption to provide secure storage and selective records access. The proposed system was analyzed using Wireshark to evaluate the overall system's performance in terms of integrity and accessibility while sharing patient records. This project aims to provide automated system keeper using autonomous agents collaboratively with the role of blockchain for further enhancement.

Blood transfusion is an integral part of the healthcare system that plays an important role in ensuring the quality of care for patients undergoing a variety of medical procedures and treatments. A large portion of this blood comes from voluntary donors. The existing blood donor management systems are unable to offer a reliable audit trail and traceability. Hence, there is a significant risk that patients may get transfusion of blood from unreliable sources. In this paper, we propose a system built on Ethereum with the goal of creating a decentralized, transparent, traceable, and secure network of blood donors. The platform uses smart contracts to facilitate peer-to-peer interactions. To encourage donors to donate blood more regularly, the system also offers rewards in the form of tokens. Our source code is available in a public Github repository1.

Donating blood is a common practice that has a positive effect on the lives of several individuals. Daily, the number of people in urgent need of blood continues to rise substantially. It is often challenging to find a suitable donor in case of emergency. The situation is worse if it is a rare blood group. This paper introduces a blockchain-based decentralised application (DApp) to match recipients with blood donors during an emergency. Personal information such as name, location, blood group, and donation history is stored securely in the blockchain distributed ledger through IPFS. The donors' lack of awareness and motivation are the primary reasons for people not coming forward for blood donations. We propose to gamify the blood donation process by issuing NFT badges as a reward for donors. This paper explains the design of smart contracts for storing donor and recipient data on the ledger and issuing NFTs to donors. The article also briefly discusses the process of designing the DApp.

The rapid growth of modern technologies has encouraged non-profit organizations (NPOs) to harness such technologies to better serve the charity sector, especially in relation to charity donation processes. Non-profit organizations primarily rely on fundraising that may involve opaque operations, which leads to the exacerbation of fears that donations may be used for illegal purposes or not reach deserving people. The necessity of charity donations traceability system is inevitable to overcome such concerns, which have an adverse impact on doners’ trust in the donation process. In this study, we propose a blockchain-based donation traceability framework intended to enable all involved parties to trace the progress of charity donations from the moment they are given by donors to the moment they reach the intended recipients. The system is built on a public-permissioned blockchain on the Ethereum platform, with every transaction being recorded as a block in the chain. These blocks of information are immutable and visible to all parties, and they also enable timely and traceable transactions. The proposed framework’s effectiveness is evaluated using a hybrid qualitative approach and proves to improve the traceability of charity donations overcoming the uncertainty associated with current systems.

In Pakistan, existing blood control systems or blood information management systems are limited in terms of efficient data retrieval of donor to consumer. There is no communication network in place for extra blood in one location to be demanded from a region if blood is limited, resulting in blood wastage. Due to a lack of accessibility and sufficient blood quality testing, blood contaminated with illnesses such as HIV has been used for transfusion in some cases. This study proposes a ledger blood management system to address these challenges. The trail has been represented as a supply-chain management problem following the blood. By trailing the blood stream and donation a single platform for transferring blood and the problem results among blood groups, the proposed system, built on the hyperledger fabric model, adds more traceability toward the blood transfusion process. It also helps to reduce unjustified blood wastage by providing an integrated system for transferring lifeblood and the thing extracts among lifeblood banks. A web app is also designed for accessing the network for simplicity of usage and security is enhanced by implementing block chain hyperfebric ledger system through Key Value System (KVS) system.

In late 2019, we witnessed the apparition of the COVID-19 virus. It first appeared in Wuhan, China and due to people traveling worldwide, it spread globally. The world went into a global lockdown because of its exponential spread and high mortality rates. Social distancing measures, crises in the economy, and healthcare posed many challenges for scientists, researchers, and healthcare workers. To try to combat this situation, multiple vaccines were tried, tested, and created in a very short amount of time. Therefore, a robust yet transparent supply chain system is very crucial in ensuring an efficient vaccination campaign. We propose a blockchain-based vaccination supply chain system to manage the registration, storage and distribution of the vaccines. Blockchain is a decentralized, distributed ledger that records all the transactions happening between the nodes in the network. The data is stored in the ledger in the form of blocks that are linked to each other by hashes, this makes tampering with the data virtually impossible. Blockchain properties will provide a distributed system along with greater privacy, transparency, and authenticity. Smart contracts deployed will help in monitoring and tracking the proper vaccine distribution conditions against the rules and regulations given by the authorities. The tamperproof nature of blockchain would ensure the supply of proper distribution of only authentic vaccines in a timely manner and traceability of the supply chain will help in increasing the people’s trust in the vaccination campaign.

Purpose Blood cold chain (BCC) represents a system for preserving the blood during its journey from the donor to the ultimate transfusion site. Existing BCCs have many drawbacks related to information transparency and information security. Secured and real-time information sharing in BCC can bring several benefits. The purpose of this paper is to summarise the issues in typical BCCs and to explore the scope of blockchain in the management of BCCs. Design/methodology/approach Issues in the existing BCCs are identified through a narrative review. To explain the potential of blockchain in mitigating these issues, a blockchain-based traceability solution is demonstrated with respect to a particular BCC scenario. The BCC management system discussed in this study makes use of the Ethereum blockchain’s smart contract feature and internet of things (IoT) technology. The smart contract is written in the solidity programming language and tested and validated using the Remix integrated development environment. Findings BCCs are concerned with several issues both from technical and non-technical perspectives. Blockchain technology is capable of troubleshooting the issues in the existing BCCs. Combining blockchain and IoT technology enables real-time information sharing among the entities. The demonstration presented in this work depicts how the blockchain-based smart contract can support operations in a typical BCC. Research limitations/implications This paper explores the scope of blockchain in BCCs through a demonstration. To get insights into its technical and economical feasibilities, further investigations are needed. Originality/value Blockchain-based traceability system presented in this work can be adopted in BCCs to ensure the quality of blood or blood products. Blockchain-based smart contracts can aid the BCCs to achieve a proper balance between blood shortage and outdating.

Tracking the shipment of blood is difficult, and violation of maintaining critical parameters leads to wastage and spoilage. IoT sensors can be used to monitor temperature, pressure, humidity, exposed to light, broken seal, etc. In our work, we implemented and tested an Ethereum based smart contract in solidity platform. Although several research works have been carried out in the blood bank inventory system, few of them focus on its security, transparency, and traceability. Health record sharing without modification is essential. Blockchain-based blood bank systems can resolve the need for individuals to access, trace, manage, and share their health and blood-related information which is immutable. Blood traceability can increase the availability systems to blood bank system and determines the number of quantities to transport from cities to a rural area. Delay in availability, results in delay in surgery or may lead to death. The blockchain-based system is a confidential environment which acts as a communication hub between donors, doctors, testing labs, and recipients or patients. To address these issues, we have designed a blockchain-based solution for the blood bank system.

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.

More and more new health care solutions are born based on the development of science and technology. The subjects who benefit the most, in this case, are not only patients (i.e., shorter healing time, faster recovery) but also medical staff, e.g., doctors/nurses (i.e., easy monitoring of the patient’s recovery process, proposing new treatment). However, there are still products that have not found an alternative: blood and blood products. Regardless of how science and technology can affect all aspects of patient treatment as well as medical care, blood still plays an important role in the treatment method. In addition to the above, blood and blood products may only be obtained from volunteers (i.e., blood donors). The preservation process is also very difficult, and no medical facility has enough facilities to preserve them. Therefore, the current process of blood preservation and transportation is done manually and contains many potential risks (e.g., data loss, personal information collection). In addition to the above barriers, developing countries (including Vietnam) also face many difficulties due to limited facilities. It is for this reason that this paper aims at a Blockchain-based technology solution for efficient management and distribution of blood from blood products. On the one hand, the paper contributes to the limitations in the information management process of storing and transporting blood and its products in the traditional database being applied in medical facilities in the cities and provinces in the Mekong Delta (the West-South of Vietnam). On the other hand, the article offers technology-based solutions to increase transparency and reduce the fear of centralized data storage (i.e., security and privacy issues). We also implement a proof-of-concept to evaluate the feasibility of the proposed approach.

This paper provides a novel implementation of blockchain technology, and data is stored in a decentralized distributed ledger to assist information protection in blood supply chain management and prevent data loss or identity theft. The present blood supply is used exclusively from the blood of volunteers (known as donors), making blood and its derivatives one of the significant roles in treating diseases today. In particular, depending on the type of product extracted from the blood (e.g., red blood cells, white blood cells, platelets, plasma). They require different procedures and storage environments (e.g., time, temperature, humidity). However, the current blood management processes are done manually - where all medical staff does all data entry. Additionally, data about the complete blood donation process (e.g., blood donors, blood recipients, blood inventories) is held centrally and is challenging to examine accurately. Therefore, ensuring centralized data security is extremely difficult because of stealing personal information or losing data. In this study, we present the blockchain technology-based blood management process and offer Blood and Product-Chain, a decentralized distributed ledger that stores data to address these restrictions. Specifically, we target two main contributions: i) we design the Blood and Product-Chain model to manage all relevant information about blood and its products based on blockchain technology, and ii) we implement the proof-of-concept of Blood and Product-Chain by Hyperledger Fabric and evaluate this in the two scenarios (i.e., data creation and data access).
