标题： Chain Table: Protecting Table-Level Data Integrity by Digital Ledger Technology

摘要： 区块链和数字账本技术（DLT）的兴起已获得广泛关注。 不再依赖传统的中心化数据权威，区块链系统由在分布式网络中共享的数字纠缠区块数据组成。 专门设计的链式数据结构及其共识机制保护区块链数据免受未经授权的对手篡改。 然而，实施一个完整的区块链系统来保护数据库在技术上可能很繁琐。 在本工作中，我们引入了一种数据库内设计，称为链表，以在不需要区块链系统的情况下保护数据完整性。 它具有简洁的设计，没有显著的技术障碍或存储开销。 为了实现严格的数据安全，我们还为链表提出了一套数据写入原则。 我们证明，链表与数据写入原则一起将保证灵活的数据完整性，称为表级数据完整性（TDI）。 显示英文摘要

摘要： The rise of blockchain and Digital Ledger Technology (DLT) has gained wide traction. Instead of relying on a traditional centralized data authority, a blockchain system consists of digitally entangled block data shared across a distributed network. The specially designed chain data structure and its consensus mechanism protect blockchain data from being tampered by unauthorized adversaries. However, implementing a full-fledged blockchain system to protect a database can be technically cumbersome. In this work, we introduce an in-database design, named chain table, to protect data integrity without the need for a blockchain system. It features a succinct design without significant technology barriers or storage overhead. To realize rigorous data security, we also propose a set of data writing principles for the chain table. We prove that the chain table, together with the data writing principles, will guarantee flexible data integrity, named table-level data integrity (TDI).
