lockchain technology has gained significant attention over the years for its potential to revolutionize various industries, including finance, supply chain management, agriculture, and healthcare. The key feature that makes blockchain technology secure and transparent is its decentralized nature, which relies on a network of nodes to validate transactions. In this research article, we propose a novel approach to model blockchain using the core-shell model. The proposed model provides a better understanding of the underlying mechanism of blockchain technology and helps in identifying the critical factors that affect the blockchain’s performance. To treat our contribution, we answered in this manuscript the following research questions: How can blockchain networks be designed and modeled in a more standardized and modular way? What is the core-shell model, and how can it be applied to blockchain modeling? How can the use of the core-shell model impact the efficiency and effectiveness of blockchain networks? What are the potential benefits and limitations of using the core-shell model for blockchain modeling?
