The development of Internet of Things (IoT) technology has promoted the prosperity of the smart device market. Smart devices provide consumers with a higher level of intelligent experience and can collect consumer data through sensors, enabling platforms to obtain additional demand spillover benefits. This has led to the entry of some IoT platforms into the smart device market, directly competing with smart device manufacturers. In this study, we analyze the impact of different market structures in the smart device market on manufacturers' innovation decisions and platform service pricing decisions within a supply chain composed of an IoT platform and a smart device manufacturer. We also examine the impact of platform entry on the quality, prices, and profits of both parties' products. The research indicates that when the smart device market is not fully covered, platforms can promote manufacturer innovation through price discounts and thus obtain higher demand spillover benefits. Furthermore, when the platform enters the market, the quality of both parties' smart devices increases, but the platform's product price is lower than the manufacturer's despite its higher product quality. Finally, we also find that when demand spillover is significant, platform entry is always driven by platform profits, but is not beneficial to manufacturers.

Decentralized Autonomous Organizations (DAOs) have seen exponential growth and interest due to their potential to redefine organizational structure and governance. Despite this, there is a discrepancy between the ideals of autonomy and decentralization and the actual experiences of DAO stakeholders. The Information Systems (IS) literature has yet to explore whether DAOs are the optimal organizational choice fully. Addressing this gap, our research asks, "Is a DAO suitable for your organizational needs?" We derive a gated decision-making framework through a thematic review of the academic and grey literature on DAOs. Through five scenarios, the framework critically emphasizes the gaps between DAOs' theoretical capabilities and practical challenges. Our findings contribute to the IS discourse on blockchain technologies, with some ancillary contributions to the IS literature on organizational management and practitioner literature.

Blockchain capacity constraints induce congestion when many users want to transact at the same time, challenging the usability of cryptocurrencies as money. This paper argues that blockchain capacity constraints, coupled with the need to incentivize miners (validators) to maintain blockchain security, lead to low inflation outcomes when cryptocurrencies compete for user demand. If two coins are both used as medium of exchange, a low-inflation coin must experience higher congestion than a high-inflation coin; otherwise demand for the latter is zero. Coin issuers then strategically undercut each other's money growth rates to boost transaction demand, limiting the overall inflation rate of the economy. However, the equilibrium is necessarily inefficient given unrealized gains from trade due to congestion and the cost of maintaining blockchain security.

Decentralized Autonomous Organizations (DAOs) represent a new and emerging form of organizing that leverages algorithmic technologies, automating many processes traditionally managed by humans. DAOs represent a radical shift as they rely on blockchain-enabled automated decision-making, diverging from the continuous human-driven decision processes that define traditional organizations. This conceptual paper examines DAOs as a critical case, questioning their place within the broader scope of organizational theory. More specifically, we discuss whether DAOs, often seen as embodiments of ‘algorithmic order,’ challenge conventional notions of organization, traditionally centered on human decision-making or ‘decided order.’ By juxtaposing gradual theories of organization, which emphasize the degree of organization through human decision-making, with theories of algorithmic organizing, we aim to uncover the unique dynamics of DAOs. This analysis underscores the need for revisiting and possibly expanding organizational theories to accommodate emerging digital phenomena like DAOs. Ultimately, DAOs serve as a pivotal case for probing the evolving boundaries of what constitutes an organization in the digital age.

This paper considers the "DeFi intermediation chain"-the market structure that underlies the creation and distribution of ETH, the native cryptocurrency of Ethereum-to examine how information asymmetry shapes intermediation rents.We argue that using proof-of-stake blockchain technology in DeFi leads to a novel limit to arbitrage, arising from the tension between arbitrageurs' privacy needs and blockchain transparency.Using a new dataset which distinguishes private and public transactions in Ethereum, we find that a 1% increase in private information advantage leads to a 1.4% increase in intermediaries' profit share.We develop a dynamic bargaining model that predicts information market power stems exclusively from participants' private information advantage.Our analysis illustrates how blockchain technology can sustain arbitrage opportunities despite low entry barriers.

The e-commerce market heavily relies on e-coupons, and their digital nature presents challenges in establishing a secure e-coupon infrastructure, which incurs maintenance costs. To address this, we explore using public blockchains for the e-coupon system, providing a highly reliable decentralized infrastructure with no maintenance costs. Storing coupon information on a blockchain ensures tamper resistance and protection against double redemption. However, using public blockchains shifts gas cost responsibility to users, potentially impacting user experience if not managed carefully. This paper focuses on cost-effective management of multiple e-coupons on Ethereum-based chains by minimizing reading and writing to storage. It applies the NFT standard with implicit ownership for creating, transferring, and removing coupons from circulation, utilizing bitmaps for efficient execution of these operations. Coupon information is stored in unused bits of a mapping that associates coupon id with the owner’s address, ensuring more economical transaction for executing e-coupon business logic. Additionally, the findings outlined in this paper hold significance to all platforms that represents services or goods as NFTs, embedding features in a single storage slot.

As blockchains shift from energy-hungry Proof-of-Work to capital-intensive Proof-of-Stake, they trade electricity costs for a new vulnerability: the risk of a capital run that can destabilize consensus and security. We model investors who choose between staking their coin to earn rewards or exiting to cash out, potentially triggering mass withdrawals. These "staking runs" are more likely when protocols are weak, when failure would hit coin prices hard, or when staking rewards are low. Leverage worsens things: margin calls accelerate exits and amplify run dynamics. Longer lock-up periods slow the run but may not prevent it. Previous research shows that low rewards are good for protocol security. We show they also raise the risk of a run. A run on a major Proof-of-Stake chain---like Ethereum---could destabilize the entire crypto ecosystem, threatening DeFi platforms that depend on it.

Mobile smart contracts (MSCs) are essential to facilitate quick, safe, and decentralized transactions on mobile blockchain networks. Scalable blockchain solutions facilitate the establishment of a mobile blockchain ecosystem characterized by enhanced resilience and adaptability. This encourages an increase in the number of users and, thus, spreads the adoption of blockchain technology in the mobile domain. With the inception of blockchain technology, a wide range of applications use smart contracts due to their high customizability. However, problems with scalability and resource-intensive consensus procedures prevent their general use. Therefore, by conducting a systematic survey using Kitchenham’s guidelines of available scalable blockchains and consensus methods, this work seeks to identify and analyze these constraints. Out of a preliminary pool of 2,073 publications, our study, which consists of 25 selected studies, identifies 12 consensus mechanisms and 13 scalable blockchain systems. Our investigation shows that, despite the wide range of techniques, no existing blockchain solution provides the scalability and lightweight operating requirements to implement smart contracts on mobile devices. This realization draws attention to a significant gap in academic and industry-driven blockchain research that may have implications for the creation of MSCs. Our findings encourage academics to explore scalable and energy-efficient blockchain technology, targeting the creation of more approachable smart contracts designed with mobile devices in mind.

Global finance is redefining grand strategy and influence in the 21st century. There is no practical alternative today that has the scale to challenge the U.S.-led financial system. With it, American influence has been projecting its strategic goals through sanctions, causing unease among international friends and foes alike, applying a pressure referred to as “weaponized interdependence.” However, state-backed digital currencies, developed for efficiency and financial inclusion, are now being considered around the world as a defense against being cut off from the global financial system—and by extension American sanctioning power. This paper will analyze the concept of weaponized interdependence in payment systems, the British financial empire as a historical precedent for it, and how America came to inherit this enviable position. This paper will also analyze what central bank digital currencies (CBDCs) are, the challenge they pose to American financial power, and offer an initial down payment on policy solutions that policymakers may consider to preserve American financial power.

Business models integrate activities for value creation and capture. While ecosystems have emerged as potent catalysts for value creation through collaborative innovation, the common understanding is that value capture occurs within individual firms. This paper challenges this dichotomy. In an empirical study using a polar types case approach, we first illustrate how two ecosystems employ decentralization technology, specifically blockchain-based Web3 platforms, to elevate value capture to the ecosystem level. We then outline the implications beyond the blockchain domain using two non-Web3 cases. Specifically, we show—from the perspectives of value proposition, value constellation, and profit equation—how business models can rise to the ecosystem level.
