Blockchain Technology - China\u27s Bid to High Long-Run Growth
Despite having the second largest economy at 1,000 to ). This is a noteworthy accomplishment since many other developing nations have fallen victim to economic stagnation within this range leading to the term âmiddle-income trapâ. This paper will argue that one of the ways in which China escaped the middle-income trap and will continue to grow its economic influence is through the support of blockchain technology. Research and development, early technological adoption and business climate all play a role in explaining how the Chinese public and private sector have used blockchain technology to encourage economic growth. While there are many questions and misconceptions about blockchain technology and its place in China, this paper seeks only to answer a select few
The political imaginaries of blockchain projects: discerning the expressions of an emerging ecosystem
There is a wealth of information, hype around, and research into blockchainâs âdisruptiveâ and âtransformativeâ potential concerning every industry. However, there is an absence of scholarly attention given to identifying and analyzing the political premises and consequences of blockchain projects. Through digital ethnography and participatory action research, this article shows how blockchain experiments personify âprefigurative politicsâ by design: they embody the politics and power structures which they want to enable in society. By showing how these prefigurative embodiments are informed and determined by the underlying political imaginaries, the article proposes a basic typology of blockchain projects. Furthermore, it outlines a frame to question, cluster, and analyze the expressions of political imaginaries intrinsic to the design and operationalization of blockchain projects on three analytic levels: users, intermediaries, and institutions.</p
GeoCoin:supporting ideation and collaborative design with location-based smart contracts
Design and HCI researchers are increasingly working with complex digital infrastructures, such as cryptocurrencies, distributed ledgers and smart contracts. These technologies will have a profound impact on digital systems and their audiences. However, given their emergent nature and technical complexity, involving non-specialists in the design of applications that employ these technologies is challenging. In this paper, we discuss these challenges and present GeoCoin, a location-based platform for embodied learning and speculative ideating with smart contracts. In collaborative workshops with GeoCoin, participants engaged with location-based smart contracts, using the platform to explore digital `debit' and `credit' zones in the city. These exercises led to the design of diverse distributed-ledger applications, for time-limited financial unions, participatory budgeting, and humanitarian aid. These results contribute to the HCI community by demonstrating how an experiential prototype can support understanding of the complexities behind new digital infrastructures and facilitate participant engagement in ideation and design processes
On Using Blockchains for Safety-Critical Systems
Innovation in the world of today is mainly driven by software. Companies need
to continuously rejuvenate their product portfolios with new features to stay
ahead of their competitors. For example, recent trends explore the application
of blockchains to domains other than finance. This paper analyzes the
state-of-the-art for safety-critical systems as found in modern vehicles like
self-driving cars, smart energy systems, and home automation focusing on
specific challenges where key ideas behind blockchains might be applicable.
Next, potential benefits unlocked by applying such ideas are presented and
discussed for the respective usage scenario. Finally, a research agenda is
outlined to summarize remaining challenges for successfully applying
blockchains to safety-critical cyber-physical systems
Apports des Smart Contracts aux blockchains et comment créer une nouvelle crypto-monnaie
Dans ce travail de recherche, est expliquĂ© ce qu'est la blockchain et son fonctionnement, mais aussi ce qu'est une crypto-monnaie et un Smart Contract. En particulier, quelles sont les possibilitĂ©s et les problĂ©matiques Ă©mergentes avec l'arrivĂ©e des Smart Contracts. De plus, ce travail aboutit Ă la rĂ©alisation pratique d'un projet, utilisant des Smart Contracts pour crĂ©er une crypto-monnaie locale Business to Business, permettant aussi de faire des prĂȘts Ă 0% d'intĂ©rĂȘt. Ce projet est Ă©galement conçu comme une aide montrant comment programmer des Smart Contracts. Il apportera les outils et les connaissances nĂ©cessaires dans le but de pouvoir crĂ©er, soi-mĂȘme, sa propre crypto-monnaie ou toute autre application dĂ©centralisĂ©e
