Bhalla, A.Ranjan, K.Patidar, K.Manjappa, M.2026-02-062024Proceedings of CONECCT 2024 - 10th IEEE International Conference on Electronics, Computing and Communication Technologies, 2024, Vol., , p. -https://doi.org/10.1109/CONECCT62155.2024.10677059https://idr.nitk.ac.in/handle/123456789/28893Blockchain technology has revolutionized various industries by offering decentralized and transparent systems for data storage and transaction processing. However, as blockchain networks continue to grow in scale and complexity, challenges related to efficiency and security in data retrieval have become increasingly prevalent. In this paper, a novel bidirectional blockchain architecture is proposed, which introduces a forward pointer alongside the traditional backward pointer to address these challenges effectively. By enhancing data retrieval efficiency and boosting network security, the proposed architecture offers significant advancements in the field of blockchain technology. We also demonstrate the efficiency of the bidirectional blockchain in searching and data retrieval in a supply chain management system, overcoming existing limitations in the traditional blockchain architecture. Through a comprehensive analysis and evaluation, this paper showcases the effectiveness of the bidirectional blockchain approach in overcoming these challenges, paving the way for enhanced performance and reliability in decentralized systems. © 2024 IEEE.Bidirectional blockchainblock mininghashingsupply chain management
