Blockchain technology finds application in multiple sectors, including renewable energy. Numerous blockchain-based applications aim to provide support in the production, management, distribution, and consumption of green energy. The benefits offered are not only technological but also social, environmental, and economic. The purpose of this study i...

Technical debt refers to decisions made during the design and development of software that postpone the resolution of technical problems or the enhancement of the software’s features to a later date. If not properly managed, technical debt can put long-term software quality and maintainability at risk. Self-admitted technical debt is defined as the...

In the last century, the increased urbanization and population growth produced a dramatic increase in waste production, causing serious problems for the environment and human health like never before. Currently, correct waste management represents a serious challenge that can be faced through the use of new technologies. Blockchain technology is a...

We discuss the contribution of the Petri net formalism to the BOSE for Smart Contract design and development. We address this discussion based on the analysis of recently published literature works we obtained by querying Scopus and Google Scholar. Different types of Petri nets, including coloured Petri nets and workflow nets, and different types o...

This paper focuses on the concept of blockchain soulbound tokens, their potential applications, and their implementation in Ethereum-based blockchains. Soulbound tokens add an important piece to blockchain technology, as they could be the key to building Web3 and a trustworthy decentralized society. Issued and strictly linked to an account, represe...

Blockchain is a disruptive technology that is changing the dynamics of numerous societal contexts. Interest in this technology is growing in both the academic and social spheres. Different blockchains usually work as isolated worlds that cannot communicate. The research and implementation of efficient interoperability protocols between blockchains...

Decentralized blockchain platforms support the secure exchange of assets among users without relying on trusted third parties.

We present a set of tests on a real permissioned blockchain where nodes are maintained by different independent public organizations in various geographic sites. Such configuration sets up real working conditions where a permissioned blockchain is not ruled and run by a single entity. Used platform is Ethereum-Hyperledger BESU implemented through d...

Soulbound Tokens were introduced last May by Vitalik Buterin as a new kind of non-fungible, non-transferable token in the Ethereum ecosystem. The main idea behind such tokens is that they are born and die at the same address without ever changing ownership. Because there is typically no one-to-one correspondence between blockchain addresses and peo...

The use of blockchain oracles is becoming increasingly widespread as it responds to the problem of providing the blockchain with external data automatically. In this paper, we focus on the use of blockchain oracles for the certification of articulated data. In particular, we show how it is possible to design and implement a DApp capable of providin...

Transmission and Distribution Systems Operators are facing the need for new market tools able to evaluate the potential of flexibility contracting, with smart and decentralized energy production, consumption, and exchange. The blockchain technology, has been proposed in platforms and projects for energy trading, given that BC platforms natively sup...

In the last years, the improvements in distributed ledger technologies brought disruptive improvements in the management of distributed energy resources.

It is conceived to exploit the IoT technology of smart meters...

We present a novel strategy, based on the Extract, Transform and Load (ETL) process, to collect data from a blockchain, elaborate and make it available for further analysis. The study aims to satisfy the need for increasingly efficient data extraction strategies and effective representation methods for blockchain data. For this reason, we conceived...

The goal of the Special Issue is to gather sound scientific papers on the theoretical and practical aspects related to blockchain technologies and smart contracts. The main focus is on the application to blockchain and smart contract development of studies pertaining to the relevant main areas of computer science. Topics may include but are not lim...

We present an application of the BOSE and ABCDE development methodology to build a DApp system for managing real world contracts for temporary workers so that, by design, agreements, commitments and rules are respected for the specific domain and employment sector and so that employers and employees are safeguarded by design. This includes the poss...

The Sardinia island is a well-known tourist destination for holidays, famous for its coasts and its beautiful sea but also for its food. Tourism is one of the most expanding sectors of the regional economy and the use of innovative technology becomes a key element to keep abreast of the times.
