Nakamoto, S. (2008). Bitcoin: A peer-to-peer electronic cash system. https://bitcoin.org/bitcoin.pdf outlined an alternative to the current monetary system in which banks are replaced by a peer-to-peer system to issue and transfer digital money: the Bitcoin. While Bitcoin has attracted a substantial investment volume, the system has not achieved the status of a viable alternative monetary system. However, the distributed ledger technology (DLT) underlying the payment system is being applied successfully by financial institutions and is likely to have important implications for the future of money and banking. In this paper we therefore focus on the most advanced distributed ledger application in the financial industry: R3 Corda. This paper is structured as follows. In the first section, we relate the debate about systems of money creation to the rise of Bitcoin. Next, the development of R3 Corda is discussed and the lessons learned for monetary reform. We conclude with an assessment of the scope and likelihood of monetary reform as a consequence of DLT applications by central banks.

This report is the final report for the FPGA accelerated PID controller, part of the Distributed Control Systems project. This project runs within the Lectoraat Robotics and High Tech Mechatronics of Fontys Hogeschool Engineering Eindhoven. The Lectoraat has the goal to develop applicable knowledge to support education and industry. This knowledge is acquired with projects run in conjunction with the industry. The report will go into detail for the software designed for this project, not the hardware design. This report is intended for follow up students working on the Distributed Control Systems project. Within this report the assumption is made that the reader is at least familiar with the terms EtherCAT, FPGA, Linux and PID controllers. However for each part a small basic introduction is included. For readers looking for the accomplishments in this project, the results are in chapter six. Following are short descriptions of the chapters in this report. The first chapter will give a short introduction to the project. It talks about why the project was conceived, where the project was done and what the expected end result is. The second chapter, the problem definition, talks about how the project has been defined, what is included and what is not and how the customer expects the final product to function and look like. The third chapter details the methodology used during this project. All the research preformed for this project will be described in the forth chapter. This chapter goes into the research into the Xilinx Zynq 7000 chip, Beckhoff's EtherCAT system, how the Serial Peripheral Interface works and how a PID controller functions. Following in chapter five the design is expanded upon. First the toolchain for building for the Zynq chip is explained. This is followed by and explanation of the different software parts that have been designed. Finally chapters six and seven provide the results and the conclusions and recommendations for this project.

MKB-bedrijven op het gebied van architectuur, gebiedsontwikkeling, ontwerp, digital design en technologie-ontwikkeling zien een nieuwe ‘markt’ ontstaan in de toenemende interesse voor de stedelijke commons. Dat zijn lokale gemeenschappen waarin mensen resources zoals energie, mobiliteit of woonruimte met elkaar delen en beheren, op een duurzame en pro-sociale manier. MKB-bedrijven zien kansen om in co-creatie met deze leefgemeenschappen nieuwe diensten en producten te ontwikkelen waarmee bewoners hun hulpbronnen gemeenschappelijk kunnen managen. MKB-bedrijven zien de ontwikkeling van stedelijke commons daarnaast als mogelijke oplossing voor urgente maatschappelijke vraagstukken en missies op het gebied van inclusieve woningbouw, duurzaamheid en de energietransitie. Voor het goed functioneren van de commons is een heldere articulatie en implementatie van hun onderliggende (maatschappelijke) waarden essentieel. Dit vraagt van MKB-bedrijven een zoektocht naar nieuwe manieren van gebieds- en technologie-ontwikkeling in samenwerking met bewoners. Een specifiek probleem daarbij betreft het vertalen van de commons-waarden naar een technologisch systeem dat het gezamenlijk beheer van hulpbronnen mogelijk maakt. Hiervoor wordt veel verwacht van digitale platformen en distributed ledgers technologies zoals de blockchain. Dit zijn databases die precies bijhouden wie wat bijdraagt en gebruikt. Ze koppelen zo’n boekhouding ook aan rechten, plichten en reputaties van de deelnemers. Bij de inrichting van zo’n systeem moeten ontwerpers steeds keuzes maken en rekening houden met spanningen tussen bijvoorbeeld privacy en transparantie, of individuele en collectieve belangen. In dit ontwerpproces stuiten MKBs op een kennishiaat. Hoe kunnen de onderliggende (maatschappelijke) waarden van commons-gemeenschappen 1) worden gearticuleerd en 2) vertaald naar een ontwerp voor de organisatie van een stedelijke commons met behulp van digitale platformen? Dit onderzoek verkent deze vragen in een fieldlab in Amersfoort, op twee ‘transfersites’ in Amsterdam en Birmingham, en met community of practice partners. Samen met hen worden een set design-principes en richtlijnen ontwikkeld voor het ontwerp van DLTs voor de stedelijke commons.
The integration of renewable energy resources, controllable devices and energy storage into electricity distribution grids requires Decentralized Energy Management to ensure a stable distribution process. This demands the full integration of information and communication technology into the control of distribution grids. Supervisory Control and Data Acquisition (SCADA) is used to communicate measurements and commands between individual components and the control server. In the future this control is especially needed at medium voltage and probably also at the low voltage. This leads to an increased connectivity and thereby makes the system more vulnerable to cyber-attacks. According to the research agenda NCSRA III, the energy domain is becoming a prime target for cyber-attacks, e.g., abusing control protocol vulnerabilities. Detection of such attacks in SCADA networks is challenging when only relying on existing network Intrusion Detection Systems (IDSs). Although these systems were designed specifically for SCADA, they do not necessarily detect malicious control commands sent in legitimate format. However, analyzing each command in the context of the physical system has the potential to reveal certain inconsistencies. We propose to use dedicated intrusion detection mechanisms, which are fundamentally different from existing techniques used in the Internet. Up to now distribution grids are monitored and controlled centrally, whereby measurements are taken at field stations and send to the control room, which then issues commands back to actuators. In future smart grids, communication with and remote control of field stations is required. Attackers, who gain access to the corresponding communication links to substations can intercept and even exchange commands, which would not be detected by central security mechanisms. We argue that centralized SCADA systems should be enhanced by a distributed intrusion-detection approach to meet the new security challenges. Recently, as a first step a process-aware monitoring approach has been proposed as an additional layer that can be applied directly at Remote Terminal Units (RTUs). However, this allows purely local consistency checks. Instead, we propose a distributed and integrated approach for process-aware monitoring, which includes knowledge about the grid topology and measurements from neighboring RTUs to detect malicious incoming commands. The proposed approach requires a near real-time model of the relevant physical process, direct and secure communication between adjacent RTUs, and synchronized sensor measurements in trustable real-time, labeled with accurate global time-stamps. We investigate, to which extend the grid topology can be integrated into the IDS, while maintaining near real-time performance. Based on topology information and efficient solving of power flow equation we aim to detect e.g. non-consistent voltage drops or the occurrence of over/under-voltage and -current. By this, centrally requested switching commands and transformer tap change commands can be checked on consistency and safety based on the current state of the physical system. The developed concepts are not only relevant to increase the security of the distribution grids but are also crucial to deal with future developments like e.g. the safe integration of microgrids in the distribution networks or the operation of decentralized heat or biogas networks.
