Influencia algorítmica e inmutabilidad de los Smart Contacts: ¿cómo impactan estas tecnologías en la asimetría contractual?
2022
En el presente trabajo nos proponenos analizar el impacto de dos tecnologías de la Cuarta Revolución Industrial en el Derecho de los Contratos, con un marcado enfoque en los sujetos vulnerables del contrato. La primera de ellas es la “inteligencia artificial” que tiene un rol preponderante al momento de la formación, celebración y análisis del contrato. Aquí nos preguntamos cómo impactan los algoritmos en la toma de decisiones, para lo cual, haremos un paso por las neurociencias. La segunda tecnología a abordar, es la denominada blockchain que se emplea en los Smart Contracts (contratos inteligentes). El eje del análisis radicará en una de sus más destacadas características: la inmutabilida…
An Efficient and Privacy-Preserving Blockchain-Based Authentication Scheme for Low Earth Orbit Satellite Assisted Internet of Things
2022
Recently, integrating satellite networks (e.g. Low-earth-orbit satellite constellation) into the Internet of Things (IoT) ecosystem has emerged as a potential paradigm to provide more reliable, ubiquitous and seamless network services. The LEO satellite networks serves as a key enabler to transform the connectivity across industries and geographical border. Despite the convenience brought from the LEO satellite networks, it arises security concerns, in which the essential one is to secure the communication between the IoT devices and the LEO satellite network. However, some challenges inheriting from the LEO satellite networks need to be considered : 1) the dynamic topology; 2) the resource…
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…
Incentive Mechanism for Edge Computing-Based Blockchain: A Sequential Game Approach
2022
The development of the blockchain framework is able to provide feasible solutions for a wide range of Industrial Internet of Things (IIoT) applications. While the IIoT devices are usually resource-limited, how to make sure the acquisition of computational resources and participation of the devices will be the driving force to realize blockchain. In this work, an edge computing-based blockchain framework is considered, where multiple edge service providers (ESPs) can provide computational resources to the IIoT devices. We focus on investigating the trading between the devices and ESPs, where ESPs are the sellers and devices are the buyers. A sequential game is formulated and by exploring the…
Fundamentos regulatorios de los emisores y proveedores de servicios con criptoactivos
2023
En esta tesis estudiamos la regulación de los criptoactivos y de los agentes económicos que los incorporan en sus procesos de negocio. Esto lo efectuamos principalmente desde la perspectiva de sus fundamentos regulatorios. En esa línea, presentamos en la primera parte un análisis jurídico de los orígenes de las tecnologías de registro distribuido, el blockchain y los primeros criptoactivos: las monedas virtuales o criptomonedas, pues de sus fundamentos seminales extraemos importantes reflexiones para la respuesta jurídica que se despliega sobre ellos. Luego, efectuamos una aproximación a la teoría de la regulación económica, específicamente a la regulación sectorial financiera, pues es dent…
A Novel Optimization for GPU Mining Using Overclocking and Undervolting
2022
Cryptography and associated technologies have existed for a long time. This field is advancing at a remarkable speed. Since the inception of its initial application, blockchain has come a long way. Bitcoin is a cryptocurrency based on blockchain, also known as distributed ledger technology (DLT). The most well-known cryptocurrency for everyday use is Bitcoin, which debuted in 2008. Its success ushered in a digital revolution, and it currently provides security, decentralization, and a reliable data transport and storage mechanism to various industries and companies. Governments and developing enterprises seeking a competitive edge have expressed interest in Bitcoin and other cryptocurrencie…
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…
Transparency in transactive energy at distribution level
2017
A recent report from the German Energy Agency analyzes the possible introduction of the blockchain technology in energy transactions in power distribution. The issue deserves attention since the extensive digitalization of business models puts new challenges to utilities in the power sector. The German decision makers in the energy field claim that blockchain appears as a close perspective and, at the same time, the Gartner hypecycle puts this technology at the peak of inflated expectations in 2016. Diffuse perception however provides hints for further investigation on the topic. This paper provides insight into the problem of peer-to-peer energy exchange from a technical perspective, provi…
Tail Removal Block Validation: Implementation and Analysis
2018
In this paper a solution for the removal of long tail blocktimes in a proof-of-work blockchain is proposed, implemented and analysed. Results from the mainnet of the Bismuth blockchain demonstrate that the variances in the key variables, difficulty level and blocktime, were approximately halved after the tail removal code was enabled. Low variances in difficulty and blocktimes are desirable for timely execution of transactions in the network as well as reduction of unwanted oscillations in the feedback control problem.
On the road to systemic sustainability : how can cleantech facilitate the Finnish sustainability transition - a multi-layer perspective backcasting a…
2015
Sustainable development has been a dominant theme in international debate since inception. During the last decades it has gained momentum due to pressing challenges in the domains of agriculture, energy, transportation, raw materials, water and ecosystems. Finland ranks highly on many sustainable development benchmarks, but the success is imbalanced. For constructing long-term redundant sustainability and well-being, Finland needs a transition affecting policy, people and businesses. This study has an intertwined theoretical and applied objective, following a pragmatist approach. The theoretical objective is to develop a conceptual framework for analysing future oriented sustainability tran…
