    Decentralization increases the performance of the Supply Chain by distributing financial choices more evenly. The technology that is causing the biggest upheaval is the aforementioned challenges that are hampering today's supply chain are addressed by block chain, which is a cost-effective and realistic solution. Many autonomous networks, self-sufficient persons and institutions can emerge and operate in a distributed, dispersed operating environment thanks to block chain. Theblock chain’s data is unchangeable, transparent, and recorded in a distributed ledger that adheres to consensus mechanisms throughout.Hence, the data stored in it cannot be edited and forged i.e., it is trusted if the writer is trusted. Block chain also has its own advantages and setbacks: decentralized network operating in centralized computing devices. Web pages are used to captured changes in original data to malicious data, network synchronization, service outages, and other challenges are some of the issues that could arise in block chain.Thereare several entities and modules involved in the model of this Supply Chain which are tested using an efficient top-down manner in this article. The proposed supply chain management model can be adaptive to various supply chains like food, textile, healthcare and also educational institutions. A comprehensive analysis of the major-cause of numerous threats, susceptibility, and hazards is assisted on the system of supply chain management as imitated in different scenarios

    Get PDF
    Food is required by everyone daily and because of this various supply chains have to operate smoothly to deliver quality goods to nearby stores. These operations contain several different parties and each one of them performs critical tasks. These supply networks can become very complex and their management can be a hassle. This complexity creates several challenges that could be solved with a single common platform that everyone involved uses. This approach, however, would be flawed with a centralized solution, so we need to turn into decentralized solutions like distributed ledgers. Currently consumers do not know much about the food products that they buy and eat. The goal in this thesis is to research how using blockchain technology could improve food supply chains since they face several issues currently and anything that can solve or even alleviate those would over time have a big positive impact. Currently the exact origins of products are mostly unknown due to lack of transparency and lots of food is wasted and thrown away due to various reasons which is not sustainable. Technology can provide new solutions for these issues which also involves IoT devices. Combining blockchain and IoT together can provide much safer and more transparent food supply chains for the masses. There are also several other related issues with food that could be improved, including supply chain optimization, collaboration and better data sharing. The used research method in this thesis is Kitchenham's systematic literature review. The results in this thesis cover extensively how distributed systems can benefit the parties involved in the food value chain and how these could be utilized for several things. Some potential concerns with the performance of these distributed systems and their security are also discussed

    The increasing use of data-centric approaches in the fields of Machine Learning and Artificial Intelligence (ML/AI) has raised substantial issues over the security, integrity, and trustworthiness of data. In response to this challenge, Blockchain technology offered a promising and practical solution, as its inherent characteristics as a decentralized distributed ledger, coupled with cryptographic processes, offer an unprecedented level of data confidentiality and immutability. This study examines the mutually beneficial connection between Blockchain technology and ML/AI, using Blockchain\u27s inherent capacity to protect against unauthorized alterations of data during the training phase of ML models. The method involves building valid blocks of data from the training dataset and then sending them to the mining process using smart contracts and the Proof of Work (PoW) consensus method. Using SHA256 to produce a cryptographic signature for each data block improves the aforementioned procedure. The public Ethereum blockchain serves as a secure repository for these signatures, whereas a cloud-based infrastructure houses the original data file. Particularly during the training phase of Machine Learning (ML) models, this cryptographic framework is critical in ensuring the data verification procedure. This research investigates the potential collaboration between Blockchain technology and ML/AI, bolstering data quality and trust to enhance data-driven decision-making fortifying the models\u27 ability to provide precise and dependable results

    A smart contract is a digital program of transaction protocol (rules of contract) based on the consensus architecture of blockchain. Smart contracts with Blockchain are modern technologies that have gained enormous attention in scientific and practical applications. A smart contract is the central aspect of a blockchain that facilitates blockchain as a platform outside the cryptocurrency spectrum. The development of blockchain technology, with a focus on smart contracts, has advanced significantly in recent years. However research on the smart contract idea has weaknesses in the implementation sectors based on a decentralized network that shares an identical state. This paper extensively reviews smart contracts based on multi criteria analysis challenges and motivations. Therefore, implementing blockchain in multi-criteria research is required to increase the efficiency of interaction between users via supporting information exchange with high trust. Implementing blockchain in the multi-criteria analysis is necessary to increase the efficiency of interaction between users via supporting information exchange and with high confidence, detecting malfunctioning, helping users with performance issues, reaching a consensus, deploying distributed solutions and allocating plans, tasks and joint missions. The smart contract with decision-making performance, planning and execution improves the implementation based on efficiency, sustainability and management. Furthermore the uncertainty and supply chain performance lead to improved users confidence in offering new solutions in exchange for problems in smart contacts. Evaluation includes code analysis and performance while development performance can be under development.Comment: Revie
