Blockchain technology is currently revolutionizing traditional financial and business models by eliminating the need for trusted third parties. Smart contracts, a specific aspect of blockchain technology, are digital agreements that facilitate ...

A storage is a persistent memory whose contents are kept across different program executions. In the blockchain technology, storage contents are replicated and incur the largest costs of a program’s execution (a.k.a. gas fees). Storage costs are ...

The rapid growth and psudonomity inherent in blockchain technology such as in Bitcoin and Ethereum has marred its original intent to reduce dependant on centralised system, but created an avenue for illicit activities, including fraud, phishing, scams, ...

Public auditing mechanism can delegate a third-party auditor (TPA) to check the remote data integrity on behalf of data owners. However, the TPA, as an idealized and benefit-oriented entity, may not provide correct auditing results on time. To ...

Blockchain security is becoming increasingly relevant in today’s cyberspace as it extends its influence in many industries. This paper focuses on protecting the lowest level layer in the blockchain, particularly the P2P network that allows the ...

Due to the sharp increase in industrial data, cloud computing has been integrated into intelligent Industrial Internet of Things systems to store and process massive data. Since core data are key factors in the industrial production ...

Mutation testing is a powerful test adequacy assessment technique that can guarantee the deployment of deeply scrutinized and more reliable Smart Contract code. However, regularly evaluating the test suite during the evolution of a project can be ...

Ethereum blockchain has shown great potential in providing the next generation of the decentralized platform beyond crypto payments. Recently, it has attracted researchers and industry players to experiment with developing various Web3 applications for ...

The Industrial IoT is starting an enormous advancement occasion in the industrial epoch. Data security as well as privacy becomes a challenge in almost every field in the real life for the duration of monitoring and collection of data in ...

Rational miners in the blockchain may admit the validity of search results directly to conserve calculation overhead without executing the validation. Such phenomenon is known as the Verifier's Dilemma that the search results of the blockchain-...

Smart contracts are increasingly used with blockchain systems for high-value applications. It is highly desired to ensure the quality of smart contract source code before they are deployed. This paper proposes a new deep learning-based tool, MANDO-GURU, ...

Ethereum realizes the application of programs on the blockchain through smart contracts and the peer-to-peer transmission of nodes through consensus mechanisms. In this paper, through smart contracts, cache nodes and three-level cache mechanism ...

The paper aims to show how blockchain, particularly Ethereum private blockchain, performs as a record keeper for Malaysian Muslim marriage records as a case study. The study also aims to demonstrate how blockchain technology conserves marriage ...

Ethereum is the second most valuable cryptocurrency, right after Bitcoin. The most distinguishing feature of Ethereum was the introduction of smart contracts which are essentially small computer programs that sit on top of the blockchain. They are ...

Public integrity auditing enables a user to delegate a third-party auditor (TPA) to periodically audit the integrity of the outsourced data. Whereas, the security of public auditing schemes relies on the trustworthiness of TPA: once TPA misbehaves,...

Ethereum is one of the largest blockchain networks in the world. Its feature of smart contracts is unique among the other crypto-currencies and gained wider attention. However, smart contracts are vulnerable to attacks and financial fraud within ...

Copyright infringement is a serious problem in the digital media industry. The traditional watermarking methods can neither protect copyright against attacks, especially the de-synchronization attacks, nor achieve cross-platform copyright ...

Distributed Denial of Service (DDoS) attacks cause devastating effects on the web services and hence harm the digital availability. The DDoS attackers use vulnerabilities exposed through new networking technologies like wireless, mobile, IoT, ...

Ethereum smart contracts are public, immutable and distributed and, as such, they are prone to vulnerabilities sourcing from programming mistakes of developers. This paper presents SAFEVM, a verification tool for Ethereum smart contracts that makes use ...
