Title: Bitcoin Network Measurements for Simulation Validation and Parameterization
Author(s): Muntadher Fadhil Sallal, Gareth Owen, Mo Adda
Keywords: Bitcoin ; Propagation delay ;Simulation Validation
Abstract: Bitcoin is gaining increasing popularity nowadays, even though the crypto-currencies field has plenty of digital currencies that have emerged before the adoption of Bitcoin idea. Bitcoin is a decentralized digital currency which relies on set of miners to maintain a distributed public ledger and peer-to-peer network to broadcast transactions. In this paper, we analyse how transactions validation is achieved by transactions propagation round trip and how transactions dissemination throughout the network can lead to inconsistencies in the view of the current transactions ledger by different nodes. We then measure the transactions propagation delay in the real Bitcoin network and how it is affected by the number of nodes and network topology. This measurement enables a precise validation of any simulation model of the Bitcoin network. Large-scale measurements of the real Bitcoin network are performed in this paper. This will provide an opportunity to parameterize any model of the Bitcoin system accurately.
