Abstract

Decentralized cryptocurrency networks, notably those with high energy demand, have faced significant criticism and subsequent regulatory scrutiny. Despite these concerns, policy interventions targeting cryptocurrency operations in the pursuit of sustainability have largely been ineffective. Some were abandoned for fear of jeopardizing innovation, whereas others failed due to the highly globalized nature of blockchain systems. In search of a more effective angle for energy policy measures, this study adopts a consumer-centric perspective, examining the sentiments of Nigerian cryptocurrency users (${n=158}$) toward Bitcoin's sustainability, a representative cryptocurrency known for its high electricity demand. Three main findings emerged: 1) Even among those self-identifying as highly knowledgeable, most considerably underestimated Bitcoin's electricity consumption. 2) Participants with a more accurate understanding of Bitcoin's energy demand were more inclined to support sustainability measures. 3) Most of this supportive cohort viewed private entities as the primary stakeholders for implementing such measures. Given these findings, we suggest that consumer education should be at the forefront of policy initiatives aimed at cryptocurrency sustainability., Comment: Early versions of this article were disseminated under the title "How to Make Users Adopt More Sustainable Cryptocurrencies: Evidence from Nigeria". Subsequently, the article has been renamed to "Energy Demand Unawareness and the Popularity of Bitcoin: Evidence from Nigeria", which is the title of the published version of record and the appropriate nomenclature for all citations of this work

7. How to make users adopt more sustainable cryptocurrencies: Evidence from Nigeria

Abstract

Some of the most popular decentralised cryptocurrency networks have drawn widespread criticism for consuming vast amounts of electricity and have thus become targets of regulatory interest. Attempts to influence cryptocurrency network operations via policy in the pursuit of sustainability in the past, however, have been widely unsuccessful. Some were abandoned out of fear of jeopardising innovation while others failed due to the highly globalised nature of decentralised systems. Considering Bitcoin as an archetype for cryptocurrencies with high energy demand, this study takes a bottom-up approach by analysing statements made by Nigerian cryptocurrency users (N = 158) concerning their perception of sustainability issues. Three main findings emerged: 1) Despite self-reporting as highly knowledgeable, most participants significantly underestimate the energy demand of Bitcoin. 2) Those who accurately assess the energy demand of Bitcoin are more likely to support measures targeting its energy demand than those who misestimate it. 3) Those who support measures predominantly hold private actors responsible. In light of these findings, it is concluded that the primary task of policy makers in the context of cryptocurrency sustainability is to enforce consumer education.

Abstract

The consumption of electrical energy is a requisite for ‘proof-of-work’, a class of consensus protocols for decentralised systems. ‘Ethereum’ and ‘Bitcoin’, along with various other cryptocurrencies, use implementations of such a consensus protocol. Among experts, the vast energy demand associated with the rising popularity of cryptocurrencies and the potential impact on climate change have been discussed extensively. It is, however, unclear what attitudes the users of cryptocurrencies themselves have towards the consequences of its growing energy demand. The proposed study aims to answer this question through survey research, using ‘Bitcoin’ as an archetype of a proof-of-work cryptocurrency. Conducting the study will reveal whether cryptocurrency users themselves consider their energy needs to be problematic, and which stakeholders they hold accountable to reduce consumption. The outcome can provide a theoretical grounding in social science for the ongoing implementation of alternative consensus models, for example in the context of the ‘Eth2’ upgrade of the ‘Ethereum’ blockchain.

Abstract

Laparoscopic Appendectomy (LPSA) is the first choice for appendectomy in pediatric surgery. Trans-Umbilical Laparoscopic Assisted Appendicectomy (TULAA) is another used technique. We compared both these procedures used for the treatment of acute appendicitis. The study was conducted between January 2019 to December 2020. Patients were divided into two groups: LPSA and TULAA groups. The collected data were: operative time, number of conversions, time of canalization and hospital stay. A total of 181 patients were included: 73 were kept in the LPSA and 108 in the TULAA group. Mean operative time was 70.9 minutes (range 45-130 min) for LPS and 56.4 (30-145 min) for TULAA group (p <0.0001). Complications rate showed no statistically significant difference between both the two groups. However, conversions showed a statistically significant difference (p=0.04). Both techniques showed similar results. TULAA technique takes a significantly shorter operating time. The selection between LPSA and TULAA techniques depends on the experience of the surgeon's work and the personal laparoscopic learning curve. In our experience LPSA was a useful technique to improve the laparoscopic skill of the pediatric surgery residents.
