However, over the last decade, significant advancements have been made in this technology, leading to diverse data security and privacy protection challenges. These challenges include transaction traceability, account pooling, Sybil attacks, eclipse attacks, and clever contract fraudulent attacks. These attacks severely violate users\u2019 data security and privacy and, therefore, must be addressed.<\/p>\n\n\n\n

There are also efforts on measuring the decentralization of nodes in Blockchain peer to peer networks. In this sense, NodeMaps have been presented, which is a decentralization of data measurement framework nodes to capture, analyze and visualize data from various popular Blockchain P2P platforms, such as Bitcoin, Lightning Network, Cosmos, and Stellar. In other words, they perform IP address analysis and provide a snapshot of each Blockchain platform to compare and contrast their nodes\u2019 geographic, ASN, and version distribution information. The measurements are evaluated to elucidate the degree of decentralization of the nodes in the underlying network of the different blockchains.<\/p>\n\n\n\n

The majority of the network participants must approve each message transmitted between the nodes through a consensus-based agreement. Furthermore, the network must be resilient to partial failures, such as when a group of nodes is rogue or when a message in transit is corrupted. For this, a good consensus mechanism used in the Blockchain must comply with two properties: persistence and vivacity. That is, if one node in the network indicates that a transaction is in the \u201cstable\u201d state, then the other nodes in the network should also report it as stable if asked and answered honestly.<\/p>\n\n\n\n
