摘 要
随着区块链技术的快速发展，智能合约作为其核心应用之一，逐渐成为学术界和工业界的关注焦点。本研究旨在设计与实现一种基于区块链的智能合约系统，以解决现有合约在安全性、可扩展性和执行效率方面的不足。为此，研究首先分析了当前主流区块链平台的技术特点及其在智能合约部署中的局限性，进而提出了一种融合形式化验证与多层共识机制的智能合约框架。该框架通过引入静态代码分析和动态运行监控相结合的方法，有效提升了合约的安全性和可靠性。同时，为优化合约执行效率，研究设计了一种自适应资源分配算法，可根据合约复杂度动态调整计算资源。实验结果表明，所提出的智能合约系统在保证安全性的前提下，显著提高了交易处理速度和资源利用率。此外，本研究还开发了一个原型系统，并通过实际案例验证了其可行性和优越性。主要贡献在于提出了创新的合约验证机制和资源管理策略，为推动智能合约在金融、供应链等领域的广泛应用提供了理论支持和技术保障。

Abstract
With the rapid development of blockchain technology, smart contracts, as one of its core applications, have gradually become a focal point of attention in both academia and industry. This study aims to design and implement a blockchain-based smart contract system to address the inadequacies of existing contracts in terms of security, scalability, and execution efficiency. To achieve this, the research first analyzes the technical characteristics of current mainstream blockchain platforms and their limitations in smart contract deployment, followed by proposing a smart contract fr amework that integrates formal verification with a multi-layer consensus mechanism. By incorporating a method that combines static code analysis with dynamic runtime monitoring, the fr amework effectively enhances the security and reliability of contracts. Simultaneously, to optimize contract execution efficiency, an adaptive resource allocation algorithm is designed, which can dynamically adjust computational resources based on contract complexity. Experimental results demonstrate that the proposed smart contract system significantly improves transaction processing speed and resource utilization while ensuring security. Furthermore, this study develops a prototype system and validates its feasibility and superiority through practical cases. The primary contributions lie in the proposal of innovative contract verification mechanisms and resource management strategies, providing theoretical support and technical guarantees for the widespread application of smart contracts in fields such as finance and supply chain management.
