DataAttest: A Framework to Attest Off-Chain Data AuthenticityDataAttest also adopts two optimization strategies to accelerate DAP verification and minimize the overhead brought by DAP construction. We implement DataAttest and evaluate it on a real-world system. The experimental results show that DataAttest can effectively check data authenticity and the overh

Collusion Attack Analysis and Detection of DPoS Consensus Mechanismpower index and Banzhaf power index in weighted voting games of DPoS, which calculated different values that DPoS suffered attacks during the voting phase. Experimental results show that collusion attacks in DPoS can be effectively detected by this method. In addition, the analysis results can furth

Decentralized Blockchain Transaction Scheme Based on Digital Commitmente commitment can be directly updated in the encrypted state and relevant parameters do not need to be transported multiple times. The transaction scheme proposed in this paper is with better efficiency and provable security, which provides a novel idea for the secure transaction framework in the blo

Research on Abnormal Transaction Detection Method for Blockchainrmal nodes and non-abnormal nodes classification model is obtained. And the abnormal transactions of blockchain is detected by using the classification model. Experimental results show that compared with traditional algorithms such as logistic regression (LR), multi-layer perceptron (MLP) and linear

The framework consists of two subsystems where the identity subsystem contains an extensible three-tier user identity model atop decentralized identity, and the agreement signing subsystem, empowered by the identity subsystem, DSN and several novel desi
