DeMonitor: Monitoring Decentralization in Blockchains using BigQuery
Jingyu Liu, Lu Liu, Zijing Li, Chao Li · 2023
In recent years, the development of blockchain technology has significantly accelerated in many countries. As a fundamental characteristic of blockchain, decentralization merits considerable attention. Nonetheless, a recent trend toward centralization has been noted, in which case the collusion of a few parties could threaten the immutability of blockchains. This paper introduces DeMonitor, a new BigQuery-based monitoring tool for blockchain decentralization. DeMonitor enables multi-dimensional and multi-level measurements of the decentralization of blockchain systems. It facilitates the monitoring and comparison of the degree of decentralization of any BigQuery-supported blockchain system.
