“…Since the introduction of Bitcoin in 2009, blockchain technology has seen a proliferation of scholarly articles investigating the potential and limitations of the technology [1,2,3,4,5,6,7,8,9,10]. Control over the system is a focal point in a significant proportion of these studies, as this either enhances or restricts the usability of blockchain [11,12,13,1,14,15,16,17,18,3,6,19,20,21,22]. Indeed, removing central control from the monetary system arXiv:2009.12542v1 [cs.CY] 26 Sep 2020 while continuing to ensure security has been considered as a core novel contribution of Bitcoin [23].…”

“…In [51], authors show that it is impossible to achieve full decentralization in permissionless blockchain networks. In [52], a novel blockchain consensus protocol is proposed based on game theory and randomness to achieve true decentralization. Literature [53] presents an information entropy method to quantify the degrees of decentralization for blockchain systems.…”

Temporary fork is a fundamental phenomenon in many blockchains with proof of work, and the analysis of temporary fork has recently drawn great attention. Different from existing efforts that focus on the blockchain system factors such as block size, network propagation delay or block generation speed, in this paper we explore a new key dimension of computing power from the miners' perspective. Specifically, we first propose a detailed mathematical model to characterize the impact of computing power competition of the mining pools on the temporary fork. We also derive closed-form formula of the probability of temporary fork and the expected mining reward of a mining pool. To reveal the long-term trends on the computing power distributions over the competing mining pools, we then develop an evolutionary game framework based on the temporary fork modeling and accordingly characterize the set of stable evolution equilibriums. Both extensive numerical simulations and realistic blockchain data based evaluation provide evidence to support our theoretical models and discoveries.

“…As the proposers know nothing about each other, collusion to fake blocks among the proposers can be avoided. After simulating the peer-to-peer consensus processes, the results show that PoTN performs better in accuracy, network overload, and efficiency than traditional consensus protocols, Tendermint [156] and PoR [157].…”

A Survey on Recent Advanced Research of CPS Security

Cyber-physical systems (CPSs) are next-generation intelligent systems that integrate computing, communication, and control. Malicious attacks on CPSs can lead to both property damage and casualties. Therefore, it is worth surveying CPS security by reviewing and analyzing the latest high-quality related works. In this paper, we provide an overview of the CPS security studies from the last five years and select 142 related works from A- or B-level conferences/journals recommended by the China Computer Federation (CCF). First, we review the main contents of the selected papers and classify them into 24 topics. Then, we analyze hotspots and trends of CPS security technologies in three dimensions: (1) architecture layers (perception, network, and application); (2) application scenarios (smart grids, health care, smart transportation, smart homes, and general grids); and (3) MADC (Measure, Attack, Defense, and Control) types. Finally, we also perform a statistical analysis in terms of paper publication times, author institutes, countries, and sponsors to show the current worldwide CPS security research situation.
