In this work, we acknowledge the need for software engineers to devise specialized tools and techniques blockchain-oriented development. Ensuring effective testing activities, enhancing collaboration in large teams, facilitating development of smart contracts all appear as key factors future
This paper looks at the challenges and opportunities of implementing blockchain technology across banking, providing food for thought about potentialities this disruptive technology. The can optimize global financial infrastructure, achieving sustainable development, using more efficient systems than present. In fact, many banks are currently focusing on to promote economic growth accelerate development green technologies. order understand potential support system, we studied actual...
This paper proposes a generic agri-food supply chain traceability system based on blockchain technology implementing the "from-farm-to-fork" (F2F) model currently used in European Union, which can integrate current rules and processes. The proposed allows consumer to reconstruct product history up origin order verify health quality by simple QR code scan. chosen for this purpose is Hyperledger Sawtooth, issued with writing permissions guarantee access only members recognized as legitimate...
Stablecoins claim to stabilise the value of major currencies in volatile crypto-asset market. This paper describes often complex functioning different types stablecoins and proposes a taxonomy stablecoin initiatives. To this end it relies on novel framework for their classification, based key dimensions that matter crypto-assets, namely: (i) accountability issuer, (ii) decentralisation responsibilities, (iii) what underpins asset. The analysis shows trade-off between novelty stabilisation...
In this work, we perform a comprehensive empirical study of smart contracts deployed on the ethereum blockchain. The objective analysis is to provide results features, contract transactions within blockchain, role development community, and source code characteristics. We collected set more than 10000 codes dataset meta-data regarding their interaction with blockchain from etherscan.io. examined data computing different statistics naming policies, ether balance, number transactions,...
Bloekehain - software technology used for peer-to-peer transaction platforms is being increasingly applied to alternative opportunities a variety of industries and use cases such as also in the energy sector. As now all related blockchain applications are still concept stage. This paper aims present preliminary ideas research project that we have launched collaboration with small Fintech company: Crypto-Trading project. From perspective explored how blockchain-based system integrating smart...
Summary This article proposes a blockchain oriented platform to guarantee the origin and provenance of food items in Smart Tourism Region context. Local beverage, fact, can become good combination attract tourist promote area provided that their is clearly certified. We designed developed blockchain‐based system manage an agri‐food supply chain for tracking items. By using smart contracts guarantees transparency, efficiency trustworthiness. Our particularly suitable cold since interfaces...
A smart city is a connected system in which things produce huge quantity of data. We focused the attention on monitoring environment quality urban area by means distributed network small mobile sensors that are devices Internet Things (IoT). Sensors digital measurements, useful for investigating and studying life every part city. In our vision, environmental data must be available everyone shared with citizens, but it unmodifiable. propose to solve problem storage management using disruptive...
Over the last decade, information technology has contributed significantly to evolution of financial markets, without, however, revolutionising way in which institutions interact with one another. This may be about change, as some market players are now predicting that new database technologies, such blockchain and other distributed ledger technologies (DLTs), could source an imminent revolution. paper analyses main features DLTs influence their potential adoption by discusses how use these...
The use of teledermatology in primary care has been shown to be reliable, offering the possibility improving access dermatological by using telecommunication technologies connect several medical centers and enable exchange information about skin conditions over long distances. This paper describes main points a project that we have implemented promote facilitate diagnosis diseases improve quality for rural remote areas. Moreover, present blockchain-based approach which aims add new...
A Blockchain is a global shared infrastructure where cryptocurrency transactions among addresses are recorded, validated and made publicly available in peer-to-peer network. To date, the best known important bitcoin. In this paper, we focus on particular modeling of Bitcoin by using Petri Nets formalism. The proposed model allows us to quickly collect information about identities owning recover measures statistics By exploiting algebraic formalism, reconstructed an Entities network...
Blockchain technologies and smart contracts are becoming mainstream research fields in computer science researchers continuously investigating new frontiers for applications. Likewise, microservices getting more popular the latest years thanks to their properties, that allow teams slice existing information systems into small independent services can be developed independently by different teams. A symmetric paradigm applies as well, which represent well defined, usually isolated, executable...
An ICO (Initial Coin Offering) is an innovative way to fund projects based on blockchain. The funding the selling of tokens by means decentralized applications called smart contracts written in Solidity, a programming language specific for Ethereum ICOs work volatile context and it crucial that team capable handling constant changes. Agile methods, proven practices enabling develop software presence changing requirements, could be managing uncertainty. main goals this are understand...

We present a novel strategy, based on the Extract, Transform and Load (ETL) process, to collect data from blockchain, elaborate make it available for further analysis. The study aims satisfy need increasingly efficient extraction strategies effective representation methods blockchain data. For this reason, we conceived system scalable process of clustering, provide SQL database which preserves distinction between transaction addresses. proposed satisfies cluster addresses in entities, store...
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 same address without ever changing ownership. Because there typically no one-to-one correspondence between blockchain addresses people, asserting associated with person for life strong assertion. Nevertheless, these promise to envision practical applications related personal reputation...
