Blockchain systems allow for securely keeping shared records of transactions in a decentralised way. This is enabled by algorithms called consensus mechanisms. Proof-of-work is the most prominent consensus mechanism, but environmentally unsustainable. Here, we focus on proof-of-stake, its best-known alternative. Importantly, decentralised decision-making power is not an inherent feature of blockchain systems, but a technological possibility. Numerous security incidents illustrate that decentralised control cannot be taken for granted. We therefore study how key parameters affect the degree of decentralisation in proof-of-stake blockchain systems. Based on a real-world implementation of a proof-of-stake blockchain system, we conduct agent-based simulations to study how a range of parameters impact decentralisation. The results suggest that high numbers of initial potential validator nodes, large transactions, a high number of transactions, and a very high or very low positive validator network growth rate increase decentralisation. We find weak support for an impact of changes in transaction fees and initial stake distributions. Our study highlights how blockchain challenges our under- standing of decentralisation in information systems research, and contributes to understanding the governance mechanisms that lead to decentralisation in proof-of-stake blockchain systems as well as to designing proof-of-stake blockchain systems that are prone to decentralisation and therefore more secure.

This paper employs a longitudinal perspective to examine continued system use (CSU) by individuals in utilitarian, volitional contexts when alternative systems are present . We focus on two key behavioural antecedents of CSU - habit and continuance intention - and theorise how the relationships between CSU and these antecedents evolve over time. In addition, we hypothesise how the interaction effect of habit and intention on CSU evolves temporally. Our theorising differs from extant literature in two important respects: 1) In contrast to the widespread acceptance of the diminishing effect of continuance intention on CSU in the information systems (IS) literature, we hypothesise that in our context, its impact increases with time; and 2) In contrast to the negative moderation effect of habit on the relationship between intention and CSU proposed in the literature, we posit a positive interaction effect. We collect longitudinal survey data on the use of a higher education IS from students in a European university. Our results suggest that the impact of continuance intention on CSU as well as the interaction effect between habit and intention are increasing over time. We further introduce a methodological innovation - the permutation approach to conduct the multi-group analysis with repeated measures - to the literature.

For those of you who have submitted manuscripts to EJIS previously, you will see that we are now allowing authors to submit slightly longer manuscripts than before. The previous guidance stated that a typical paper should be between 5000 and 8000 words (13,000 words for review articles), inclusive of the abstract, tables, references, figure captions, footnotes, endnotes. There are a few reasons for making this change. First, we discovered that many first submissions are well over 8,000 words. Hence the limits were not being consistently enforced anyhow. Second, 8,000 words may not be sufficient for many qualitative papers. Third, having limits that are inconsistently enforced creates a submission landscape where those who don’t know the “rules of the game” are disadvantaged. Junior scholars, for example, might follow the rules only to find out later that they have not sufficiently explained their research. Senior scholars, by contrast, might exceed the recommended word limit, knowing that there will be few, if any, consequences for doing so. Hence, this can create an inconsistent review experience. Fourth, having a 10,000-word limit for the main text, but excluding references, means that the recommended limit of review articles is about the same as before. Although we are increasing the EJIS word limit, please do not take this as an invitation to write poorly. EJIS reviewers and editors do not like waffle, nor do they like unnecessary repetition. Hence, I hope to continue receiving well-crafted papers with little repetition. I am grateful to Crispin Coombs, one of our senior editors, for raising this issue at the recent board meeting.

This paper presents and describes data for nonprofit IRS filings in the United States of America. The data contains 831 attributes and 1,102,884 records for the years 2016-2021. Among other items, the data include nonprofits’ comparative financial data, governance disclosures, and hired contractors, as well as management compensation, a detailed statement of revenue, statement of functional expenses, external audit, federal audit election, and reconciliation of net assets. The data is generated using Structured Query Language (SQL) self-developed code to convert the IRS form 990 Extensible Markup Language (XML) tax filing files to a dataset in Excel. This paper is the first to convert these XML files and provide much-needed open access to nonprofit data in a long format that is useful for researchers to conduct cross-sectional analysis. The 2,174 lines of source code that we developed, and a step-by-step guide are included in this paper.
