Halal certification assures that a product or a service has been created, processed, and delivered according to Islamic laws. Currently, the certificate is printed on a security paper and includes a QR code that can be used to verify the certificate online. However, there are some problems with the ongoing certificate verification process. The verification site is centralized, creating a single point of failure. The current verification system is also unable to detect the modified printed certificate. The research aims to propose an alternative halal certificate recording and verification system. A smart contract that runs on the Ethereum blockchain is developed and deployed for that purpose. As a result, the average certificate creation cost is US$20.035, and the process requires 5.75 seconds, while verification is free, and the result can be obtained in about one second. Utilizing the blockchain to store and verify the halal certificate increases trust in the product or service since once the data is stored, it cannot be changed and accessible to the public. Nodes around the world replicate the blockchain to ensure service availability. For future consideration, the system can be extended to automate and track the halal application process and integrated as an alternative to the current system by implementing multiple signatures in the smart contract for each party. Furthermore, the system can be integrated with a peer-to-peer sharing system such as IPFS to store the digital certificate

The growing need for access to safer food items is increasing, and hence, there is a need for a better supply chain management system in the food industry is increasing. The increased complexity of the existing systems tends to introduce more issues to the stakeholders, and also, the cost of product traceability is quite high. Hence, the industry is looking for effective solutions in relation to drug traceability, and the application of Blockchain technology enables the stakeholders in the food and beverage (F&B) sector to track the movement of goods, supported in gathering the required details so that the contaminated products can be identified and recalled without much delay and lesser recall costs to protect the lives of the individuals. The tampered food items are increasing and are impacting the supply chain process, brand name of the companies, and claim assurance. They create an adverse impact on the health of the individuals and cause higher economic loss to the health-care industry. The existing studies tend to focus on laying emphasis of the need for an enhanced, effective, and end tracking systems in the industry. The emergence of Blockchain technology enables centralized tracking of information support in enhancing the data privacy and increasing transparency and support in eradicating the tampered food products in the supply chain system. These approaches leverage the usage of smart contracts and decentralize the storage of information in a secure manner for enhanced product traceability in the F&B industry. The implementation of smart contracts generates better data governance, which tends to meet the needs and requirements of the stakeholders, and applies effective measures of food traceability. The primary objective of the study is to perform an analysis of Blockchain in enhancing drug traceability in the food sector. The researcher uses quantitative analysis for the study as it helps in understanding the critical determinants influencing drug traceability in food effectively, the survey method is used to gather the information, and past reviews are also used to possess a better understanding of the subject area effectively.

Data security or secure storage of medical information is usually a significant concern for the bulk of the population. An efficient healthcare system needs a technology platform to speak firmly and seamlessly. Block chain has been emerging technology for a few years now. The key options of block chain which attract most developers are its immutableness, decentralization, transparency, distributed ledger. We tend to propose a Healthcare Secure Information Storage System (Life Care) that firmly manages personal medical records and creates an interaction between Doctors and Patients. The Life Care system is meant to improve the current systems because it provides interoperable, secure, and effective access for medical records by patients. It provides timed-based smart contract for governing transactions and dominant access to electronic medical records. The security is ensured by using SHA-256 encryption technique with Blockchain to store hash data for providing security, new incentive mechanism that leverages the degree of health suppliers concerning their efforts in maintaining medical records and making new blocks.
