Abstract

Blockchain has the characteristics of decentralization and immutability, and has received widespread attention in recent years. Data can not be tampered, which will cause a series of problems such that malicious transactions can not be eradicated and wrong transactions can not be modified. The existing related researches can modify specific block data, or add new transactions to achieve logical editing. The former will cause the editing record can not be verified, the latter can keep the wrong data storage, but lack of secure access mechanism. In addition, the existing relevant studies have not fully considered the characteristics of the data to be edited, resulting in subsequent transactions affected and ineffective. Therefore, an editable blockchain model is proposed. Firstly, taking deposit data as an example, the underlying data structure of blockchain is redesigned, time-series attributes are added, and the index is built. Then it proposes new submission, editing and query algorithms, and realizes the logical editing of blockchain data through subsequent additional transactions, to provide users with a secure access interface on the basis of saving the wrong transaction certificate. Finally, based on the above work, the data structure and algorithms of transaction data are improved to solve the problem of subsequent transaction failure, to ensure that subsequent transactions are not affected by data editing. Experimental results show that this model can realize the editable blockchain on the basis of ensuring performance of the system.
