Lifecycle Optimization of Smart Contract for Different Scenarios in 6G Network

In the rapidly evolving landscape of the sixth generation (6G) network, smart contracts emerge as a pivotal technology for enforcing trustful rules. However, the conventional lifecycle model of smart contracts – encompassing stages from initiation to the termination of a contract instance – suffers from rigidity and lack of customization, leading to notable operational challenges. These challenges primarily manifest as heightened resource demands, including longer waiting periods and escalated transaction costs, which hinder the adaptability of smart contracts in the varied and dynamic contexts of 6Gconnected environments. Driven by these issues, this paper conducts a comprehensive analysis of the smart contract lifecycle.We introduce an innovative lifecycle model that offers customizable flexibility, allowing for the merging or separation of different stages in the smart contract process. Meanwhile, we propose a unique transaction data structure designed to integrate parameters of combined stages, each marked with distinct identifiers for differentiation. Further, we introduce an innovative address scheme for smart contract instances, which provides an identifier to simplify instance access while also maintaining a mechanism for traditional access methods. The verification results show that the model can save 52.72% of processing fee and 68.09% of completion time compared with the conventional method.
