Abstract

The immutability is a crucial property for blockchain applications, however, it also leads to problems such as the inability to revise illegal data on the blockchain and delete private data. Although redactable blockchains enable on-chain modification, they suffer from inefficiency and excessive centralization, the majority of redactable blockchain schemes ignore the difficult problems of traceability and consistency check. In this paper, we present a Dynamically Redactable Blockchain based on decentralized Chameleon hash (DRBC). Specifically, we propose an Identity-Based Decentralized Chameleon Hash (IDCH) and a Version-Based Transaction structure (VT) to realize the traceability of transaction modifications in a decentralized environment. Then, we propose an efficient block consistency check protocol based on the Bloom filter tree, which can realize the consistency check of transactions with extremely low time and space cost. Security analysis and experiment results demonstrate the reliability of DRBC and its significant advantages in a decentralized environment.

基于去中心化变色龙哈希的动态可读区块链

不变性是区块链应用程序的一个关键属性，然而，它也会导致诸如无法修改区块链上的非法数据和删除私有数据等问题。虽然可读区块链支持链上修改，但它们存在效率低下和过度中心化的问题，大多数可读区块链方案忽略了可追溯性和一致性检查的难题。本文提出了一种基于去中心化变色龙哈希（DRBC）的动态可读区块链。具体来说，我们提出了一种基于身份的去中心化变色龙哈希（IDCH）和一种基于版本的交易结构（VT）来实现去中心化环境中交易修改的可追溯性。然后，我们提出了一种基于Bloom过滤器树的高效块一致性检查协议，该协议可以以极低的时间和空间成本实现交易的一致性检查。安全性分析和实验结果证明了DRBC的可靠性及其在分散环境下的显著优势。
