Smart Contracts on Ethereum for Smart Supply Chain Management
Chetan D. Bawankar1,*,Latika C. Bawankar2,Yogesh S. Deshmukh1,Abhijit S. Bodhe3Abstract
Raw materials are manually produced, and data is often stored and managed insecurely, leading to increased overall time and dissatisfaction among clients. Blockchain technology, with its decentralization and robust security, revolutionizes data storage by improving data security, time management, and transaction efficiency. This chapter examines the use of Ethereum-based smart contracts to enhance supply chain management, streamline transactions, safeguard data, and optimize time management. By establishing legally binding agreements, smart contracts reduce ambiguity in operations. However, Smart Contract Management (SCM) tags are costly and have limited lifespans. Supply chain management is inherently sensitive, and logistics require strict confidentiality to protect product information. The study aims to decouple supply chain processes from data security concerns, addressing the challenges posed by outdated systems that have persisted for decades. Key areas of focus include inventory management, product quality, and resolving supply-demand discrepancies, with data security being a critical priority. This proposed solution integrates smart contracts and peer-to-peer encryption, leveraging the immutability of blockchain ledgers to prevent unauthorized access by hackers. Registered users gain secure website access, ensuring controlled data sharing. Cryptographic methods further enhance transaction security, while damaged products can be retained as evidence for dealer compensation. This approach is not only secure and effective but also instills greater customer confidence during transactions. By modernizing supply chain systems, this study demonstrates the potential to transform the industry, making operations more efficient, user-friendly, and reliable.
INTRODUCTION
The rapid advancement of blockchain technology has unlocked innovative applications across various fields, with supply chain management being a prominent beneficiary. Blockchain's core features—transparency, traceability, and security—are essential for managing the complexities of modern supply chains. To fully harness these advantages, integrating smart contracts has proven to be a transformative solution.
Smart contracts are self-executing agreements with terms directly encoded into their framework, eliminating the need for intermediaries and ensuring transactions and processes are executed automatically when predetermined conditions are met. This chapter highlights Ethereum, a leading blockchain platform, as the foundation for implementing smart contracts in supply chain systems. Efficiently managing the flow of goods within a company's supply chain is crucial in today’s interconnected global economy, where it plays a significant role. Supply chain management (SCM) is commonly defined as the process of transferring goods from producers to consumers.
SCM encompasses various stages, beginning with raw materials and ending with the end customer. These stages typically include producers, distributors, and retailers. Goods are sourced, packaged, and transported to their destinations through a series of coordinated steps. While traditional supply chain management offers several advantages, it often falls short of fully adhering to regulatory standards. For example, assigning product quality and allowing the final consumer to reverse transactions highlight some of its limitations. Forward flows, such as the movement of goods from their source to the destination, are among the most common processes in the field.
The rapid advancement of blockchain technology has introduced groundbreaking applications across various fields, particularly in supply chain management (SCM) [1]. Blockchain's transparency and immutability offer significant advantages for modernizing traditional supply chain methods. By providing a secure framework for collecting data and executing automated scripts or applications, known as smart contracts, blockchain has the potential to transform SCM. Smart contracts, which are self-executing agreements embedded in code, allow supply chain managers to track the origin and safety of goods while supporting reverse flows, such as product returns and refunds, fostering a more trustworthy global market [2].
This research develops a conceptual framework for an SCM system using blockchain and smart contracts. The goal is to ensure secure transactions and deliver high-quality products to customers. Blockchain, a continuously growing ledger of transactions linked and secured by cryptography, requires verification by the majority of nodes in the network [3]. Once validated, blocks are added to the chain across all nodes, enhancing security and transparency. However, managing multiple instances of the same data remains resource-intensive.
Blockchain's decentralized nature ensures data integrity, as it cannot be altered or hacked. There are three primary types of blockchains: public (permissionless), private (permissioned), and consortium. Each has unique characteristics tailored to its geographical or operational context. According to Szabo, smart contracts are “computerized transaction protocols that fulfill contract conditions.” These contracts are typically written in high-level programming languages such as Java, Python, or Solidity, with Ethereum being a notable platform for deploying them [4, 5]. Hyperledger, for example, employs NodeJS and Python for its smart contracts, while Ethereum uses solidity to create secure and publicly accessible scripts that execute autonomously within a protected environment.
Cryptocurrency plays a pivotal role in blockchain systems, serving as a digital asset for secure transactions and block creation. Cryptocurrencies like Bitcoin rely on blockchain technology for functionality. Blockchain protocols govern network interactions, enabling cryptographic authentication and facilitating the use of tokens and smart contracts. Coins and tokens, though related, differ in purpose [6, 7]. Coins are tied to a blockchain protocol, while tokens represent specific applications or ideas built on that protocol. For instance, miners are rewarded with cryptocurrency, which can also be used for third-party transactions.
Supply chain management has become increasingly vital in the global market. However, it faces numerous challenges, including the need for trust between buyers and sellers, secure transactions, and the elimination of intermediaries who can manipulate market values for personal gain. Many organizations lack encrypted systems to store private information, leaving them vulnerable to cyberattacks [8, 9]. Additionally, there is often limited price transparency due to intermediary influence. The current system primarily supports one-way movement of goods, leaving consumers to bear the risks associated with defective products. Manual processes and human errors further exacerbate inefficiencies, leading to increased costs and difficulty in identifying root causes [10-12].
The importance of SCM in the global economy cannot be overstated, as it directly impacts market stability. Blockchain technology has been proposed as a solution for supply chain risk management, addressing issues like operational risks, trade authenticity, repayment risks, and contingent risks. For example, in the pharmaceutical industry, blockchain mechanisms can enhance supply chain management by integrating with existing systems to improve information sharing, security, and efficiency. This research introduces a blockchain-based information-sharing framework utilizing smart contracts and consensus mechanisms to provide cryptographic keys securely to all stakeholders [13, 14].
Studies, such as one by Alfonso-Lizarazo et al., highlight the benefits of integrating forward and backward logistics in supply chains, such as in the palm oil industry [15]. Beyond its traditional role as a decentralized ledger, blockchain extends to broader decentralized network applications, including distributed decision-making, resource sharing, and communication protocols. Smart contracts act as a bridge between these concepts, enabling trust-based automation without relying on centralized systems, thus revolutionizing supply chain processes [16, 17].
Statement of the Problem
Supply chain management systems face challenges daily that demand prompt attention and resolution. These challenges can vary in complexity and severity. Utilizing cloud computing offers several benefits, such as meeting customer expectations, ensuring high standards of quality and sustainability, and effectively managing supplier relationships. However, the number of challenges confronting supply chain management continues to grow annually, particularly as concerns about security intensify. A failure in the supply chain will inevitably impact a company’s financial stability and overall performance [18-20].
Motivation
Blockchain technology employs distributed node consensus mechanisms, encryption, and intelligent script code to ensure secure data transmission and access. This framework enables the validation and storage of data while introducing a new paradigm for distributed computing and infrastructure, allowing for programming and data management.
Within a blockchain system, each participant's transaction data is stored in a data block, which is then linked sequentially to form a chronological chain of data blocks [21, 22]. Consequently, modifications to the main data structure are impossible without impacting other sections of the chain. Only new information can be added, and any changes require approval from a specified percentage of participants. Furthermore, existing data cannot be altered or deleted. The identity of each participant and the transaction details between entities are made open and transparent, promoting consistency and transparency in decision-making [23].
Methods and Methodology
This section provides an in-depth review of various strategies and tools. Instead of representing a physical supply chain, the model illustrates an information service chain built on blockchain technology. Every transaction is securely recorded on the blockchain, making the logistics industry's activities a source of data for the blockchain system. In other words, the calculation of start and end times for data systems within a blockchain-powered digital environment accurately reflects the operations of the supply chain, commonly referred to as smart contract design. This concept applies specifically to electronic contracts [24-28].
Case Study
A study demonstrates how Ethereum can ensure efficient resource allocation and secure data sharing in IoT-based systems [33]. This approach safeguards data exchange and resource management for mobile IoT sensors operating in a distributed environment. Smart contracts were implemented to automate resource allocation and regulate the secure transfer of data between sensors, which reduced computational overhead, enhanced data integrity, and fostered trust among network entities.
Technical Aspects: Ethereum smart contracts were employed for authentication and access control, incorporating gas-efficient designs to optimize resource usage for mobile devices. Scalability challenges were addressed using Layer 2 solutions, which managed the increased volume of data exchanges effectively.
BMW’s blockchain initiative focused on tracking the provenance of components in automotive manufacturing. It addressed inefficiencies in managing global suppliers and part recalls [34]. Smart contracts automated vendor payments once delivery was verified, reducing transaction errors and streamlining procurement processes. Ethereum Layer 2 solutions, such as Polygon, were used to achieve cost-effective scaling.
Resource Management and Secure Data Exchange: Ethereum’s role in managing IoT systems involves deploying smart contracts for operations like sensor registration, resource allocation, and data exchange.
Gas Costs: Frequent updates in sensor readings posed challenges due to gas fees, which were mitigated by implementing gas-efficient smart contract designs.Transaction Speed: Real-time sensor data exchange was achieved by utilizing Layer 2 solutions to overcome the base-layer transaction speed limitations of Ethereum.
