Incentive Mechanism for Edge-Computing-Based Blockchain
2020
Blockchain has been gradually applied to different Internet of Things (IoT) platforms. As the efficiency of the blockchain mainly depends on the network computing capability, how to make sure the acquisition of the computational resources and participation of the devices would be the driving force. In this work, we focus on investigating incentive mechanism for rational miners to purchase the computational resources. A edge computing-based blockchain network is considered, where the edge service provider (ESP) can provide computational resources for the miners. Accordingly, we formulate a two-stage Stackelberg game between the miners and ESP. The aim is to investigate Stackelberg equilibriu…
Blockchain Disrupting Fintech and the Banking System
2021
Nowadays society is profoundly changed by technology, velocity and productivity. While individuals are not yet prepared for holographic connection with banks or financial institutions, other innovative technologies have been adopted. Lately, a new world has been launched, personalized and adapted to reality. It has emerged and started to govern almost all daily activities due to the five key elements that are foundations of the technology: machine to machine (M2M), internet of things (IoT), big data, machine learning and artificial intelligence (AI). Competitive innovations are now on the market, helping with the connection between investors and borrowers—notably crowdfunding and peer-to-pe…
An Energy Blockchain, a Use Case on Tendermint
2018
The recent advances in distributed energy systems require new models for exchanging energy among prosumers in microgrids. The blockchain technology promises to solve the digital issues related to distributed systems without a trusted authority and to allow quick and secure energy transactions, which are verified and cryptographically protected. Transactions are approved and subsequently recorded on all the machines participating in the blockchain. This work demonstrates how users, which are nodes of the energy and digital networks, exchange energy supported by a customized blockchain based on Tendermint. We focus on the procedures for generating blocks and defining data structures for stori…
Initial Coin Offering (ICO) as a Fundraising Strategy : A Multiple Case Study on Success Factors
2019
Cryptocurrencies and Initial Coin Offerings (ICO) are some of the more prominent examples of currently used blockchain technology applications. Especially software startups have leveraged ICOs to gain funding early on in their lifecycles, going on to develop and create new blockchain based applications. Recently, larger companies such as Facebook have also begun to show interest in cryptocurrency, although thus far not for funding purposes in the form of ICOs. In this paper, we investigate factors that positively affect the abilities of companies to meet their fundraising goals via ICOs. We first identify a set of factors from extant literature and then seek to further confirm the effect of…
Blockchain and Smart Contracts: New Perspectives on Copyright Protection in the Digital Single Market
2022
New technologies making use of blockchains and smart contracts have been considered an efficient and innovative way to achieve the goal of effective copyright protection in the digital market. It is impossible to deny, however, that these innovative technologies raise serious questions about their compatibility with international, European, and national legislative frameworks, at least if we compare them with the original and most widely-used blockchain model (i.e., the so-called permissionless blockchain). Indeed, permissionless blockchains create a “law-free zone” resistant to any subsequent modification and judicial intervention. In this general context, this chapter aims to analyse the …
Is blockchain technology compatible with the Social and Solidarity Economy? Towards a new paradigm
2019
La significativa evolución que las tecnologías de la información han experimentado en los últimos años ha afectado a todos los sectores, incluido el de la Economía Social y Solidaria. El desarrollo emergente de la tecnología blockchain y sus posibilidades para modificar las formas de colaboración solidaria de la ciudadanía, presentan un reto actual y un cambio de paradigma para el Tercer Sector. El objeto del presente artículo es analizar las posibilidades existentes de que ambos ámbitos compartan valores, principios y objetivos. Para ello, en primer lugar y como punto de referencia, se presentan los conceptos de Economía Social y Solidaria y de blockchain. A continuación, se presentan las …
La tecnología Blockchain en la construcción de espacios económicos de impacto social positivo
2021
espanolEste trabajo realiza un estudio del universo de la tecnologia blockchain y su aplicacion en el mundo del siglo XXI a traves del analisis de diferentes espacios virtuales construidos con ella. El objetivo ultimo de este analisis es valorar y comprender las posibilidades que esta tecnologia aporta en la construccion de procesos con un alto impacto social y/o ambiental. A tal efecto, se lleva a cabo una investigacion exploratoria a traves del estudio de casos significativos o pioneros desde una perspectiva socio-tecnologica. Los resultados concluyen que, si bien en sus origenes la tecnologia blockchain se estructuro con una marcada perspectiva financiera, el transcurso del tiempo ha dem…
Improving cooperation in cross-border insolvency issues by means of blockchain technology
This paper, which was presented at the 50th anniversary UNCITRAL-Congress (Vienna, 4-6 July 2017), suggests using blockchain technology in order to improve cooperation between the parties involved in cross-border insolvency proceedings.
A Test Bench for a Blockchain-based Management of Smart Prosumers' Flexibility
2022
To date, the European regulatory framework requires the development of new energy policies at the national level that can reduce overall consumption and support the implementation of customer-focused control and management systems. Therefore, it is necessary to study the feasibility of the various strategies available, especially for the involvement of residential users in services that can contribute to the management of the electricity grid. The advent of blockchain technology has enabled the development of new business models for the electricity market, opening this world to end users who previously did not have the opportunity to participate in energy trading and allowing the implementa…
A Peer-to-Peer Market Algorithm for a Blockchain Platform
2020
In an era of technological revolution in which everything becomes smarter and connected, the blockchain can introduce a new model for energy transactions able to grant more simplicity, security and transparency for end-users. The blockchain technology is characterized by a distributed architecture without a trusted and centralized authority, and, therefore, it appears as the perfect solutions for managing exchanges between peers. In this paper, a market algorithm that can be easily transferred to a smart contract for maximizing the match between produced and consumed energy in a micro-grid is presented. The algorithm supports energy transactions between peers (both producers and consumers) …
