A Privacy-Preserving and Auditable Scheme for Interfacing Public Blockchain with Consortium Blockchaicted to the closed consortium blockchain environment, and the end-users who do not belong to the consortium are difficult to gain access without extra authentication. Thus, architectures concerning cross-chain interaction appear, while most solutions have only limited functionalities. Moreover, few

Data Cooperatives for Trusted News Sharing in Social Media approach to secure data management. Data cooperatives and blockchain are an excellent combination since they share fundamental features like decentralization and democratic design. In this paper, we leverage the power of blockchain to design a trusted news-sharing system for social media. We prove

SoK: Can NFTs Solve the Economic Problems of Countries with Ancient Heritage? Egypt as a Case Studyat NFTs. We believe that NFTs, especially with MetaVerses, came as a bless to nations with ancient heritage that attract tourists. Online tourism existed from the year 2000, and nowadays with COVID-19 travelling restrictions along with the advance of VR/AR/XR museum tours many projects are there and

Scalable Smart Contracts for Linear Regression Algorithmand time-consuming. In this work, we propose a novel implementation of smart contracts for linear regression algorithms with fraction-based computation that can train and predict on the Ethereum blockchain. Our smart contract-based training and prediction technique with Solidity programming language

A Secure Microgrid Power Transaction Scheme Based on Hyperledger Fabricntinuous double auction mechanism to solve the possible malicious bidding problem. In addition, the multi-signed address wallet is used to ensure the transaction security of users without a trusted center. Finally, the security and feasibility analysis of the paper proves the effectiveness of the sc
