Traceability Platform Based on Green Blockchain: An Application Case Study in Dairy Supply Chain

Abstract

Recent progress in IoT and software development has simplified data acquisition and immutability of information in the agri-food supply chain. In the last few years, several frameworks and applications were proposed to ensure traceability in the agri-food-sector using distributed ledger technologies (DLT) such as Blockchain technologies. Still, no other study has presented a Blockchain-based traceability platform with a lower impact on the environment and lower cost for each transaction sent by the supply chain. This article presents a traceability platform based on Green Blockchain with low energy consumption and costs savings applied to the Fontina PDO cheese supply chain, part of the project “Typicalp”, funded by the European Union (EU). The proposed traceability system is based on Algorand Blockchain, which uses the Pure Proof-of-Stake mechanism of consensus that requires minimal computational power, is highly scalable and environmentally sustainable. In addition to the environmental and financial benefits, the developed traceability platform has made it possible to digitize the entire production chain, making the data immutable and available in real-time for Fontina consortium operators and final consumers.

Information Traceability Model for the Grain and Oil Food Supply Chain Based on Trusted Identification and Trusted Blockchain

“…Compared with Reference [ 6 ], this paper adopts the blockchain master–slave multi-chain architecture to trace and supervise data information, and uses the open-source framework Hyperledger Fabric as the development platform, which is more efficient in data security, reliability and economic practicability. In line with sustainable agricultural development, Reference [ 34 ] proposes a green blockchain-based traceability platform with low energy consumption and cost savings, suitable for the Fontina PDO cheese supply chain. The traceability system it proposes is based on the Algorand blockchain, which uses pure proof-of-stake consensus, requires minimal computing power, and is highly scalable and environmentally sustainable.…”

“…The traceability system it proposes is based on the Algorand blockchain, which uses pure proof-of-stake consensus, requires minimal computing power, and is highly scalable and environmentally sustainable. Compared with the literature [ 34 ], this paper adopts the master–slave multi-chain architecture of blockchain, and the main chain adopts the PoW consensus mechanism, and the slave chain adopts the PBFT consensus mechanism, which has certain advantages in terms of transaction throughput and speed.…”

“…Lin et al proposed a food safety traceability prototype system based on blockchain and EPC information services, and avoided the problems of data tampering and sensitive information leakage that may occur in the process of information interaction through the Ethereum smart contract [ 33 ]. Varavallo et al proposed a green blockchain traceability platform based on the Internet of Things and blockchain technology, which provides an environmentally friendly and low-cost traceability solution for food traceability [ 34 ].…”

Differential Game Model of Information Sharing among Supply Chain Finance Based on Blockchain Technology

“…The green and safe driving behavior of logistics drivers, ecological design, and environmental performance of the whole supply chain are systematically monitored. Alongside the improved transparency of carbon credit through the trust mechanism, carbon-emission trading mechanisms within the supply chain can be promoted [20][21][22], thus enhancing the circularity of the supply-chain system [23][24][25][26]. Second, the supply chain provides credit loans to many SMEs that cannot be financed by banks to solve their financial problems, providing a large number of jobs for society and reducing the unemployment rate.…”

“…At present, most studies on blockchain technology in supply-chain finance adopt various analytical methods such as literature analysis, qualitative analysis, and evolutionary game [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38]. These studies analyze the application of blockchain technology in the supplychain finance models, development situations, and the benefit distribution of supply-chain members.…”
