Bitcoin and Ethereum are frequently promoted as decentralized, but developers and academics question their actual decentralization. This motivates further experiments with public permissionless blockchains to achieve decentralization along technical, economic, and political lines. The distribution of tokenized voting rights aims for political decentralization. Tokenized voting rights achieved notoriety within the nascent field of decentralized finance (DeFi) in 2020. As an alternative to centralized crypto-asset exchanges and lending platforms (owned by companies like Coinbase and Celsius), DeFi developers typically create noncustodial projects that are not majority-owned or managed by legal entities. Holders of tokenized voting rights can instead govern DeFi projects. To scrutinize DeFi's distributed governance strategies, we conducted a multiple-case study of non-custodial, Ethereum-based DeFi projects: Uniswap, Maker, SushiSwap, Yearn Finance, and UMA. Our findings are novel and surprising: quantitative evaluations of DeFi's distributed governance strategies reveal a failure to achieve political decentralization.
Art and collectibles markets tend to involve lower liquidity and higher fees than public equity markets. Distributed ledger technology can tokenize artworks and collectibles, so that claims to these assets can be exchanged digitally without intermediaries. Tokenization offers investors access to a global market plus a digitized paper trail, as well as new options for the fractional ownership of artworks, art-collateralized loans, and yield-bearing art assets. The main challenge for tokenization researchers and platform developers is to simultaneously satisfy regulators’ demands for transparency and auditability as well as art investors’ demands for privacy. New technological solutions are required that enable market participants to disclose the absolute minimum amount of information that is demanded by regulators. We investigate how distributed ledger technology, cryptography, and digital identity management can help address this challenge.
User-centric identity management systems are gaining momentum as concerns about Big Tech and Big Government rise. Many of these systems are framed as offering Self-Sovereign Identity (SSI). Yet, competing appropriation and the social embedding of SSI have resulted in diverging interpretations. These vague and value-laden interpretations can damage the public discourse and risk misrepresenting values and affordances that technology offers to users. To unpack the various social and technical understandings of SSI, we adopt an 'interpretive flexibility' lens. Based on a qualitative inductive interview study, we find that SSI's interpretation is strongly mediated by surrounding institutional properties. Our study helps to better navigate these different perceptions and highlights the need for a multidimensional framework that can improve the understanding of complex socio-technical systems for digital government practitioners, researchers, and policy-makers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
