Private households are increasingly taking cooperative action to change their energy consumption patterns in pursuit of green, social, and economic objectives. Cooperative demand response (DR) programs can contribute these common goals several ways. To quantify potential, we use detailed production data collected from 201 Austin (Texas) over the year 2014 as well historic real-time prices wholesale market. simulate DR, adapt a load-scheduling algorithm support both retail capacity-pricing...

Bitcoin and Ethereum are frequently promoted as decentralized, but developers academics question their actual decentralization.This motivates further experiments with public permissionless blockchains to achieve decentralization along technical, economic, political lines.The distribution of tokenized voting rights aims for decentralization.Tokenized achieved notoriety within the nascent field decentralized finance (DeFi) in 2020.As an alternative centralized crypto-asset exchanges lending...

Abstract This fundamentals article discusses efficient machine economies in which non-human agents can autonomously exchange information and value. We first identify criteria for achieving Pareto efficiency such by drawing on the Coase Theorem. then translate these economic to technical requirements before developing a framework that characterizes four types of economies. discuss real-life examples each type highlight key challenges efficiency. In particular, we with human involvement...

Blockchain technology has the potential to resolve trust concerns in cross-organizational workflows and reduce reliance on paper-based documents as anchors. Although these prospects are real, so is regulatory uncertainty. In particular, reconciliation of blockchain with Europe’s General Data Protection Regulation (GDPR) proving be a significant challenge. We tackled this challenge German Federal Office for Migration Refugees. Here, we explain how used Action Research guide creating...

Cross-organizational collaboration and the exchange of process data are indispensable for many processes in federally organized governments. Conventional IT solutions, such as cross-organizational workflow management systems, address these requirements through centralized architectures. However, centralization is difficult often undesirable federal contexts. One alternative solution that emphasizes decentralized a architecture blockchain Germany’s Federal Office Migration Refugees. Here, we...

Fragmentation and limited accessibility of charging infrastructure impede the adoption electric vehicles.To improve availability independent providers, eRoaming offers a promising solution.Yet, current systems are typically centralized, which raises concerns market power concentration.While use blockchain technology can obviate such concerns, it comes with significant privacy challenges.To address these challenges, we explore combination self-sovereign identity.Specifically, apply design...
