In recent years, more and more companies require dedicated software to increase the efficiency of their business. However, with rapidly changing technologies it is often inefficient to maintain a dedicated team of developers. On the other hand, ...

Although the primary role of decentralized ledgers, such as blockchains in cryptocurrencies, is to store data related to interactions between users to establish trust within incognizant parties, their capabilities allow them to offer more sophisticated ...

Recently, mesh networking and blockchain are two of the hottest technologies in the telecommunications industry. Combining both can reformulate Internet access. While mesh networking makes connecting to the Internet easy and affordable, blockchain on ...

In recent years, the increasing concerns around the centralized cloud web services (e.g. privacy, governance, surveillance, security) have triggered the emergence of new distributed technologies, such as IPFS or the Blockchain. These innovations have ...

Low power communication is a major milestone for the Internet of Things (IoT). Low-Power Wide-Area Network (LPWAN) technologies seek to provide a large coverage area and long battery life at the cost of a reduced bandwidth compared to traditional ...

Current anti-counterfeiting supply chains rely on a centralized authority to combat counterfeit products. This architecture results in issues such as single point processing, storage, and failure. Blockchain technology has emerged to provide a promising ...

Though the 2 Phase Commit protocol (2PC) remains central to distributed database management, it has a provably-inevitable vulnerability to blocking even when a distributed system guarantees the most demanding synchrony or timing-related requirements. ...

A specific number of transaction confirmation blocks determines average time of receiving and accepting payments at cryptocurrencies, and the shortest confirmation time for the same level of blockchain security provides the best user properties. ...

This paper articulates the notion of the cryptocitizen who thinks freely of the traditional dictates of authority. The analysis looks beyond the immediate economic benefits and risks of blockchain technology to consider the broader implications for the ...

Proof of Work systems are used in cryptocurrencies to obtain consensus in distributed peer-to-peer systems that share no trust. Miners of cryptocurrency compete by engaging in the Proof of Work to solve a cryptographic challenge. The first to ...

The use of blockchain technology to track physical assets is not new. However, the state of the art concepts are not applicable due to several limitations. One limitation is the scalability of blockchains with regard to the number of transactions that ...

Blockchain is a powerful and distributed platform for transactions which require a unified, resilient, transparent and consensus-based record keeping system. It has been applied to scenarios like smart city, supply chain, medical data storing and ...

Many IoT devices lack memory and computational complexities of modern computing devices, making them vulnerable to a wide range of cyber attacks. Among these, DDoS attacks are a growing concern in IoT. Such attacks are executed through the introduction ...

Bitcoins and Blockchain technologies are attracting the attention of different scientific communities. In addition, their widespread industrial applications and the continuous introduction of cryptocurrencies are also stimulating the attention of the ...

This paper makes the case for the use of blockchains in emerging intelligent transportation systems applications. Specifically, we argue for the use of blockchains to settle contracts and transactions in a variety of intelligent transportation ...

Many companies rely on Cloud infrastructures for their computation, communication and data storage requirements. While Cloud services provide some benefits, e.g., replacing high upfront costs for an IT infrastructure with a pay-as-you-go model, they ...

Climate change represents a serious threat to the health of our planet and imposed a discussion upon energy waste and production. In this paper we propose a smart grid architecture relying on blockchain technology aimed at discouraging the production ...

In this vision paper, we present an approach that makes it possible to protect developed ideas and early concepts even during their systematical development. We take the Design Thinking process as an example, in which interfaces are used for individual ...

In this paper, we explore the use of the Stellar Consensus Protocol (SCP) and its Federated Byzantine Agreement (FBA) algorithm for ensuring trust and reputation between federated, cloud-based platform instances (nodes) and their participants. Our ...
