Security Enhancement and Performance Assessment in Blockchain-based Smallholder Palm Oil Supply Chain

Ensuring robust security systems is critical, particularly for smallholder palm oil supply chains. This study aims to enhance the security and efficiency of blockchain-based supply chains for smallholder palm oil by exploring the integration of certificate authorities, multi-channel schemes, and smart contract integration. This article focuses on the implementation of security systems in blockchain-based supply chains for smallholder palm oil using Certificate Authority (CA), Multi-Channel Scheme (MCS), and Smart Contract Integration (SCI). The methods used included problem identification, data collection and analysis, privacy and security model development, prototype development, system privacy and security evaluation, and system performance measurement. The results show that implementing these security systems can significantly improve security, efficiency, data integrity, authentication, and trust in palm oil supply chains. Performance measurement is used to evaluate transactions and the implementation of security mechanisms implemented in the system by measuring throughput, send rate, latency, and resource utility. Our research addresses security, efficiency, and performance in blockchain-based smallholder palm oil supply chains by introducing certificate authorities, a multi-channel scheme for data segregation, and a novel smart contract framework, and evaluating their combined impact on system performance metrics. The research provided insights into ongoing efforts to secure and optimize smallholder palm oil supply chains and offered insights into these technologies' practical applications and benefits. These findings provided valuable recommendations for the adoption and integration of these technologies in the palm oil industry to improve supply chain security, transparency, trust, traceability, and efficiency.
