Multi-attribute Blockchain Decentralization Degree Measurement Model
Decentralization is a typical feature of blockchain.With the continuous development of blockchain technology,the prac-tical significance of quantitative measurement of decentralization degree is gradually deepening.The evaluation indicators used in the existing blockchain decentralization degree measurement methods either consider the node function or the network perfor-mance,and the different evaluation angles lead to a large deviation between the proposed model and the evaluation indicators.To this end,this paper focuses on the blockchain transaction process,extracts the key factors that affect the degree of decentraliza-tion of the blockchain from three aspects:node function integrity,network transmission and data storage,establishes a multi-at-tribute decentralized degree measurement model(MDDMM)and implements the prototype.Experimental results show that the degree of influence of data storage,node function integrity and network transmission on decentralization characteristics decreases successively.The degree of decentralization of Bitcoin is about 3.5％,30％and 38％higher than that of Bitcash,Ethereum and Ethereum Classic respectively.Compared with the existing measurement methods,the MDDMM proposed in this paper has more comprehensive measurement indicators,providing theoretical basis and data support for quantifying the decentralized degree of the blockchain platform.
