“…Xu et al [ 46 ] found that the implementation of blockchain by manufacturers can increase the greenness of products and also promote supply chain optimization and coordination. Peng et al [ 47 ] found that blockchain-based smart contracts and Digital signature technology can greatly reduce double loss and achieve efficient and high quality circulation in fresh agricultural products supply chain. Feng et al [ 48 ] introduced blockchain-based traceability technology into fresh agricultural products supply chain to guarantee the credibility of agricultural products data through real-time monitoring of multiple nodes.…”

The application of blockchain can effectively improve the efficiency of fresh agricultural product circulation and consumer trust, but it can also increase investment costs. In this context, this paper introduces parameters such as blockchain unit variable cost, the level of blockchain technology investment, and consumer channel preference in two dual-channel supply chain systems dominated by fresh agricultural product manufacturers: online direct sales and distribution. It compares and analyzes pricing and channel selection strategies in both cases of not using and using blockchain. The research shows that when blockchain is used, manufacturer profits are higher in the direct sales model than in the distribution model. Traditional retailers’ profits are lower in the direct sales model than in the distribution model. Total supply chain profits are higher in the direct sales model than in the distribution model, and they exhibit an inverted "U" shape as the level of blockchain investment increases. In the online direct sales model, if the blockchain technology unit variable cost is within a certain threshold range, manufacturer profits, traditional retailer profits, and total supply chain profits are all higher than when blockchain technology is not used. In the online distribution model, when the blockchain variable cost and blockchain usage level meet certain conditions, manufacturers, traditional retailers, and online distributors all have higher profits when using blockchain technology than when not using it. This study provides theoretical guidance for the practical application of blockchain technology in dual-channel fresh agricultural product supply chains.

“…Digital technologies such as the Internet of Things, cloud computing, and blockchain are playing a crucial role in bolstering agricultural productivity (Peng et al, 2023;Tao et al, 2021). Concurrently, machine learning, robotics, and computer vision techniques are being employed to monitor environmental conditions and diagnose crop diseases, ensuring effective agricultural production (Dusadeerungsikul & Nof, 2019;Gentilhomme et al, 2023).…”

This study considers a contract farming supply chain consisting of a platform and a risk‐averse farmer with yield uncertainty. It establishes game theory models with and without digital technology under CVaR criterion and analyzes three digital cooperation mechanisms. We find that when the wholesale price is moderate, both parties will choose a cost‐sharing contract; when the wholesale price is high, both parties will choose to let the farmer bear the cost of digital investment; when the farmer uses digital technology to grow agricultural products, the platform should not provide the farmer with a low wholesale price, especially for the farmer with low risk aversion.

“…can occur during the process of entering the information into the local database, which makes it difficult to ensure the data's integrity. Third, the massive amount of video surveillance data occupies a large amount of storage space, which can very easily cause a wastage of resources [6,7]. Blockchain technology can effectively solve the aforementioned problems, and research on the storage of video data on a blockchain has become a current hot topic.…”

Cereal and oil video surveillance data play a vital role in food traceability, which not only helps to ensure the quality and safety of food, but also helps to improve the efficiency and transparency of the supply chain. Traditional video surveillance systems mainly adopt a centralized storage mode, which is characterized by the deployment of multiple monitoring nodes and a large amount of data storage. It is difficult to guarantee the data security, and there is an urgent need for a solution that can achieve the safe and efficient storage of cereal and oil video surveillance data. This study proposes a blockchain-based abnormal data storage model for cereal and oil video surveillance. The model introduces a deep learning algorithm to process the cereal and oil video surveillance data, obtaining images with abnormal behavior from the monitoring data. The data are stored on a blockchain after hash operation, and InterPlanetary File System (IPFS) is used as a secondary database to store video data and alleviate the storage pressure on the blockchain. The experimental results show that the model achieves the safe and efficient storage of cereal and oil video surveillance data, providing strong support for the sustainable development of the cereal and oil industry.
