BTDM: A Regulatory-Oriented Optimization Scheme for Bitcoin Transaction Data Organization

Abstract

As Bitcoin grows, more and more users are choosing to use Bitcoin as a means of transaction. For regulatory purposes, the need for retrieval and analysis of large amounts of bitcoin transaction data is raised. Faced with the problems of high retrieval time and cost overhead of current data retrieval tools, this paper proposes a new regulatory-oriented Bitcoin transaction data organization optimization scheme (BTDM). Firstly, BTDM reduces the index retrieval time by introducing Redis, then optimizes the data retrieval efficiency by using file offset mapping method, and finally reduces the cost of searching by transforming the data structure of transaction hash and bit mapping method. The experimental results show that BTDM has significant advantages in terms of performance and cost compared to other retrieval tools.
