Blockchain jako platforma logistyki publicznej
2020
Zarządzający sektorem publicznym coraz częściej poszukują nowych możliwości oferowania mieszkańcom większego pakietu świadczeń, przyczyniających się do podniesienia jakości życia. Jedną z ich jest logistyka publiczna, która posiada potencjał integracji i koordynacji działań w zakresie realizacji zadań publicznych. Jednak obawy sektora publicznego względem prywatnego wykonawstwa świadczeń ciągle jeszcze są stosunkowo duże. Wynika to nie tylko z braku zaufania do zewnętrznego wykonawstwa zadań, ale także z braku transparentności relacji między sektorem publicznym i prywatnym, znajdującym uzasadnienie w teorii agencji. Sposobem na poprawę relacji i optymalizację oferty w mieście może stanowić …
Challenges and directions for Blockchain technology applied to Demand Response and Vehicle-to-Grid scenarios
2021
Abstract Nowadays, Blockchain is considered a consolidated technology supporting many different applications that integrate well with Artificial Intelligence and the Internet of Things, and supports the creation of Decentralized Autonomous Organizations. Within this wider framework, the energy blockchain applications are now deserving more and more attention, since blockchain architectures, on one hand, provide transparency and solve the information asymmetry problem, on the other, provide disintermediation. In this way, the dream of an energy market closer to end-users becomes a reality, although, still, the regulatory framework is not clear, especially for what concerns the tokenization o…
A blockchain platform for Demand Response in Mediterranean islands: a smart contract for remuneration
2022
The Blorin project started at the end of 2019 to support the implementation of a blockchain platform to support the energy services provision from end users by means of Demand Response and Vehicle to Grid programs. The experimental part of the project is being carried out on two Mediterranean islands and inside the University campus in Palermo. Customized smart contracts have been designed to support the active participation of end users to regulation services for the two weak electrical grids of the islands in the view of a deep penetration of renewable energy in the two energy systems. In particular, the smart contract for remuneration accounts for the very special energy situation of isl…
Agri-food Supply Chain Traceability for Fruit and Vegetable Cooperatives Using Blockchain Technology
2019
Blockchain se ha convertido en una tecnología disruptiva que tiene la capacidad de transformar la industria agroalimentaria, puesto que promete resolver muchos problemas relacionados con la falta de confianza en la trazabilidad y el producto que adquieren los consumidores. Sin embargo, las partes implicadas en la cadena de suministro de productos agroalimentarios son numerosas y están físicamente dispersas, lo que dificulta el manejo de datos e información. Como resultado, el proceso de producción no es transparente y la confianza es difícil de construir. Para ser más exitosas en la economía globalizada actual, las cooperativas deben focalizarse en ofrecer mayor transparencia. Este document…
Demand Response Service Certification and Customer Baseline Evaluation Using Blockchain Technology
2020
The use of Distributed Ledger Technologies such as Blockchain for certifying Demand Response services allows for the creation of a distributed system in which customers can communicate with the system operator to provide their flexibility, in a secure, transparent and traceable way. Blockchain technology also supports incentive mechanisms for users taking part in the service through the generation of utility tokens to recognize the user's contribution. This paper presents the experimental test of a novel methodology for Demand Response programs implementation by using the Blockchain technology. The latter is employed for defining a distributed Demand Response service and a new system for it…
Challenges and Opportunities using MultiChain for Real Estate
2019
The real estate market involves multiple untrusted actors with contrasting objectives. We propose REchain, a blockchain-based platform for real estate, which provides benefits to all actors in terms of transparency, trust, immutability, and traceability. REchain architecture handles real estate data through well-defined workflows that leverage the MultiChain platform. REchain changes the real estate market enabling direct transactions without intermediaries, and providing new mechanisms for negotiating the purchase conditions. This paper refutes the misleading idea of using blockchains for solving generic problems as blockchain platforms have peculiar features that make them suitable for sp…
Using Blockchain in Digitalizing Enterprise Legacy Systems: An Experience Report
2021
Blockchain technology and distributed ledger technology (DLT) offer a secure, distributed, and tamper-proof way to store and exchange information. However, apart from standard cryptocurrency-based networks, innovations and process improvements based on the blockchain technology have mostly remained on the conceptualizing stage and have not yet reached mass adoption. There is a high demand for practical experiences from developing blockchain and DLT based systems in various domains outside FinTech. This work seeks to contribute to this gap by presenting real-world experiences from developing a proof of concept for automatizing conditional payments in social benefits and healthcare domains. W…
Blockchain e diritto dei contratti: criticità e prospettive
2022
Il presente contributo si propone di indagare la persistente attualità delle categorie ereditate dalla tradizione civilistica con riferimento alla contrattazione “smart” nel contesto di una Blockchain. Appurato che l’automatismo delle transazioni non può escludere l’applicazione del diritto e l’intervento regolatore dell’ordinamento, la ricerca si propone di qualificare giuridicamente lo “smart contract”, verificandone la compatibilità con i concetti di “accordo” e di “adempimento”. L’attenzione sarà, da ultimo, rivolta all’applicabilità dei rimedi tradizionali alle transazioni “smart”.
Digital rights management : blockchain and digital music content management
2017
Tämän tutkielman tarkoituksena oli ymmärtää lohkoketjuteknologian vaikutuksia digitaalisen musiikin sisällönhallintaan hyödyntäen digitaalisten tekijänoikeuden hallintajärjestelmien (DRM) viitekehystä. Tutkielma sisälsi kolme tutkimuskysymystä: mitä digitaalisia tekijänoikeuden hallintajärjestelmien haasteita lohkoketjuteknologia voisi mahdollisesti ratkaista verrattuna edellisiin DRM-teknologioihin, miten lohkoketjuteknologia liittyy DRM:n aiempiin teknologisiin haasteisiin ja mitkä ovat lohkoketjuteknologian mahdolliset vaikutukset digitaalisen musiikin tekijänoikeuden hallintajärjestelmiin. Vastaukset tutkimuskysymyksiin perustuivat kirjallisuuskatsaukseen sekä puolistrukturoituihin teem…
Aggregation and remuneration in Demand-Response with a blockchain-based framework
2020
This paper describes the possibility to use the blockchain technology for load and generation aggregation in a new distributed Demand Response (DR) service and customers remuneration system. The blockchain technology and the use of smart contracts for DR allow the creation of a distributed system in which customers can communicate directly, in a transparent, secure and traceable way, with the grid operator to provide their flexibility. In this paper, the DR problem formulation takes into account several aspects, which are periodically executed. First, the blockchain records customers’ energy consumption or production, then, the smart contract starts calculating the baseline and the potentia…
