区块链数据迁移模式
Patterns for Blockchain Data Migration
摘要：
随着技术、经济和监管环境的快速发展，当代区块链平台几乎肯定会发生重大变化。因此，依赖它们的应用程序最终需要从一个区块链实例迁移到另一个区块链实例，以保持竞争力和安全性，并增强业务流程、性能、成本效率、隐私和合规性。然而，数据和智能合约表示、托管模式、交易费用的差异，以及保持一致性、不变性和数据来源的需求，给数据库迁移带来了独特的挑战。我们首先使用一个说明性的示例来呈现一组区块链迁移场景和数据保真度水平。然后，我们提出了一组迁移模式来解决这些场景和上述数据管理挑战。最后，我们展示了如何通过选择一组合适的数据迁移模式、数据保真度水平和主动系统设计来最大限度地减少迁移的工作量、成本和风险。还强调了实际考虑和研究挑战。
英文摘要：
With the rapid evolution of technological, economic, and regulatory landscapes, contemporary blockchain platforms are all but certain to undergo major changes. Therefore, the applications that rely on them will eventually need to migrate from one blockchain instance to another to remain competitive and secure, as well as to enhance the business process, performance, cost efficiency, privacy, and regulatory compliance. However, the differences in data and smart contract representations, modes of hosting, transaction fees, as well as the need to preserve consistency, immutability, and data provenance introduce unique challenges over database migration. We first present a set of blockchain migration scenarios and data fidelity levels using an illustrative example. We then present a set of migration patterns to address those scenarios and the above data management challenges. Finally, we demonstrate how the effort, cost, and risk of migration could be minimized by choosing a suitable set of data migration patterns, data fidelity level, and proactive system design. Practical considerations and research challenges are also highlighted.
