In the snapshot taken on 14 May 2022 from the Bitcoin main network. 5. DiscussionOur findings could be used to enhance the network vitality and stability by analyzing the network resilience and security and improving the propagation mechanism. Our measurement results show that active reachable Bitcoin nodes play an essential role in the vitality and resilience of Bitcoin’s network. They allow the new joining nodes to connect to other peers and provide them with the current ledger state. For more efficient and fast data propagation, the role played by Well-connected nodes in the network could be extended. Well-connected nodes can be considered as Bitcoin Master nodes and used to improve the propagation delays. The transactions and blocks could be propagated in two steps: (1) from one cluster to other adjacent clusters in the network and (2) from Master nodes to typical peers in each cluster. For efficient data transfer between different clusters in step (1), utilizing Boundary Master nodes would avoid any redundancy in the data propagation. The powerful influence of Well-connected nodes shown by the dynamicity analysis may threaten the Bitcoin network operation. More thorough studies are required on the dynamics of Well-connected nodes to specify the danger posed to Bitcoin. 5.1. Performance ImprovementThe community structure measurement results show that active reachable Bitcoin’s nodes play an essential role in the vitality and resilience of Bitcoin’s network, as they allow the new joining nodes to connect to other peers and provide them with the current ledger state. Specifically, the role played by Well-connected nodes (nodes with more than default peer count and up-to-date ledger) could possibly be extended for more efficient and fast data propagation. Here, we provide an exemplary improvement suggestion and preliminary simulation results when applied to the network. In our proposal, Well-connected nodes can be considered as Bitcoin Master nodes and used to improve the propagation delay as follows: Considering that N n 1 , n 2 , , … , n i , is a set of nodes in the Bitcoin network where i presents the number of total nodes. M N m n 1 , m n 2 , , … , m n j , presents the Master nodes set where j presents the number of total Master nodes ( M N ⊆ N ). Considering that m n x m n x , p 1 , p 2 , … , p k where m n x presents the set of Master nodes in the given xth cluster, k is the total number of peers in the cluster. Thus, we have m n x ⊆ N and N = m n 1 ∪ m n 2 ∪ … ∪ m n x . Now, when a new node q wants to join the network, it first connects to a Special Node S N learned from the D N S seeds. The S N provides node q with the list of the available Master nodes to establish a connection with. Node q selects one
