Bitcoin transactions as a graph

Nowadays, blockchain is an upcoming area for researchers from different research fields. Bitcoin, as the first successful cryptocurrency, has accumulated numerous data after its existence. Here, Bitcoin transaction graph a theory perspective investigated with more available given now. This paper mainly focuses on and provides both practical theoretical sides of data. Several existent measurements some newer ones are computed analysed. These help to interpret extensively. A new modified Buckley–Osthus random model proposed, simulation Chung–Lu attempted represent network. Some suggestions improve point out pros cons these models. Moreover, experiments show that scale-free networks fundamentally not good considering all data, but mechanics preferential attachment crucial. How proceed experimental perspectives future studies also discussed
