Proposal of a methodology for the sustainability assessment of cryptocurrencies

As cryptocurrencies are becoming more and more widespread and their power consumption has caught the attention of the public, it seems worthwhile to investigate their effects on the environment, economy and society. In the scientific literature, a clear focus on the high power consumption of the market-dominating Bitcoin can be seen in the sustainability assessment of cryptocurrencies. In order to build a comprehensive understanding of cryptocurrencies’ sustainability other aspects should be considered as well instead of narrowing down the scope of analysis to power consumption. Therefore, a holistic definition of sustainability in the context of cryptocurrencies is proposed. Building upon this definition a methodology for assessing a cryptocurrencies’ sustainability is derived in this paper and subsequently applied to ten cryptocurrencies

At the very beginning, there\u27s this dream. The role of utopia in the workings of local and cryptocurrencies

Since the 2008 financial crisis, the number of alternative currencies aiming at transforming global financial institutions, such as local and complementary currencies (LCC) and cryptocurrencies, has exploded. Yet the motivations and workings of such monies are relatively unknown. This chapter aims to fill this gap by providing a framework that uncovers the ideals pursued by alternative currencies, and the effects of those ideals on the production of money. To do so, I present a comparative analysis of the valuation infrastructure – the processes through which value(s) is produced – of one LCC, Sol Violette, and three cryptocurrencies, Bitcoin, Ğ1 “June” and impak Coin. Throughout, I elaborate on the social meaning of money and the role played by alternative currencies in contemporary capitalism. I show that 1) despite targeting the same financial institutions, the utopia pursued by alternative currencies varies significantly and 2) this utopia is at least as important as the technology (e.g. blockchain) in shaping the workings of these monies. Based on these findings, I outline some implications for the social studies of financial technologies, their effects on our societies and their regulation

A Standalone FPGA-based Miner for Lyra2REv2 Cryptocurrencies

Lyra2REv2 is a hashing algorithm that consists of a chain of individual hashing algorithms, and it is used as a proof-of-work function in several cryptocurrencies. The most crucial and exotic hashing algorithm in the Lyra2REv2 chain is a specific instance of the general Lyra2 algorithm. This work presents the first hardware implementation of the specific instance of Lyra2 that is used in Lyra2REv2. Several properties of the aforementioned algorithm are exploited in order to optimize the design. In addition, an FPGA-based hardware implementation of a standalone miner for Lyra2REv2 on a Xilinx Multi-Processor System on Chip is presented. The proposed Lyra2REv2 miner is shown to be significantly more energy efficient than both a GPU and a commercially available FPGA-based miner. Finally, we also explain how the simplified Lyra2 and Lyra2REv2 architectures can be modified with minimal effort to also support the recent Lyra2REv3 chained hashing algorithm.Comment: 13 pages, accepted for publication in IEEE Trans.
