一句话：提出 SmartShift 框架，用智能状态划分与渐进式函数激活实现安全高效的智能合约迁移，显著降低停机时间。
区块链平台的持续演进与智能合约固有的不可变性，使跨链与链内迁移成为必要，但迁移合约中大量关键数据并在过程中保持数据完整性、最小化运营中断是重大挑战。本文提出 SmartShift 框架，通过智能状态划分（intelligent state partitioning）与渐进式函数激活（progressive function activation）来实现安全、高效的智能合约迁移，并在迁移过渡期间保持运营连续性。作者进行了综合评估，结果表明 SmartShift 显著降低了迁移停机时间，同时保证了强健的安全性，为构建高效且安全的智能合约迁移系统奠定了基础。
Blockchain and smart contracts have emerged as revolutionary technologies transforming distributed computing. While platform evolution and smart contracts' inherent immutability necessitate migrations both across and within chains, migrating the vast amounts of critical data in these contracts while maintaining data integrity and minimizing operational disruption presents a significant challenge. To address these challenges, we present SmartShift, a framework that enables secure and efficient smart contract migrations through intelligent state partitioning and progressive function activation, preserving operational continuity during transitions. Our comprehensive evaluation demonstrates that SmartShift significantly reduces migration downtime while ensuring robust security, establishing a foundation for efficient and secure smart contract migration systems.
