必需品成本的上升影响着世界上每个国家,但这已成为发展中国家的主要关切。在这些国家,跟上日常用品价格上涨的步伐变得越来越困难,大多数人口来自中产阶级或下层中产阶级。通货膨胀,大流行,战争,和其他重要变量都会导致价格上涨。可能还有另一个重要因素在起作用,这就是供应链腐败。供应链是不可靠的,混乱,这种腐败应该归咎于不透明的性质。在我们的研究中,我们专注于农业食品供应链。因为当前许多农业食品供应链错综复杂且难以监控,不诚实的政党可以利用这种情况。因此,我们建议建立一个基于区块链的农业食品供应链,以确定价格上涨的来源。在建议的系统中使用了私有以太坊区块链。由于私有以太坊区块链效率更高,安全,而且快,它被选中了。创建智能合约是为了描述系统及其基本规则和法律。此外,为了展示我们智能合约的有用性,我们展示了一个样本分散应用来支持我们的假设。我们还对系统进行了完整的安全性和漏洞评估,以确保其正常运行并免受威胁和攻击。由于区块链的使用,系统是不可变的,透明,并且易于跟踪和监控。拟议的系统显示出更大的透明度,可追溯性,可靠性,速度,安全,和成本效率相比,传统的系统。它有效地追溯了供应链中腐败的根源,提供一种更直接的手段来解决与价格上涨有关的担忧。
The rise in the cost of essentials affects every nation around the world, but it has become a major concern for developing nations. It is getting increasingly difficult to keep up with rising prices for everyday items in these countries, where the majority of the population is from the middle class or lower middle class. Inflation, pandemics, wars, and other important variables all contribute to price increases. There may be another significant factor at play, which is supply-chain corruption. The supply chain\'s unreliable, chaotic, and opaque nature is to blame for this corruption. We are concentrating on the agri-food supply chain in our study. Because many of the current agri-food supply chains are intricate and challenging to monitor, dishonest parties can exploit the situation. Therefore, we suggested a thorough blockchain-based agri-food supply chain to identify the source of price increases. The private Ethereum blockchain was used in the suggested system. Since the private Ethereum blockchain is more efficient, safe, and fast, it was chosen. Smart contracts were created to describe the system and its underlying rules and laws. Furthermore, in order to showcase the usefulness of our smart contracts, we exhibited a sample decentralized application to support our hypothesis. We also gave the system a complete security and vulnerability assessment to make sure it is operating properly and is protected from threats and attacks. Due to the use of blockchain, the system is immutable, transparent, and simple to track and monitor. The proposed system has demonstrated greater transparency, traceability, reliability, speed, security, and cost-efficiency compared to conventional systems. It effectively traces the origin of corruption in the supply chain, providing a more straightforward means to tackle concerns related to price hikes.
