Consistency Analysis of Distributed Ledgers in Fog-Enhanced Blockchains

AbstractBoth revolutionary technologies of Fog Computing (FC) and Blockchain (BC) serve as enablers for enhanced, people-centric trusted applications, they do meet in the provision higher standards expectations. In this paper, we address reliability fog-enhanced BC systems by analyzing forking phenomenon under different conditions, provide a reliable Distributed Ledger (DL) consistency assessment. We use FoBSim tool that is specifically designed to mimic emulate realistic FC-BC integration, which deploy Proof-of-Work (PoW) consensus algorithm analyze probability fluctuating conditions. Based on our results, propose an inconsistency formula, can quantitatively describe how consistent DL system be. Finally, show formula decision making model indicating optimal deployment features network Fog-enhanced system.KeywordsDistributed LedgerConsistencyBlockchainFog
