Item Talk Is Silver, Code Is Gold? Beyond Traditional Notions of Contribution in Peer Production: The Case of Drupal(Frontiers in Human Dynamics, 2021) Rozas Domingo, David; Gilbert, Nigel; Hodkinson, Paul; Hassan Collado, SamerPeer production communities are based on the collaboration of communities of people, mediated by the Internet, typically to create digital commons, as in Wikipedia or free software. The contribution activities around the creation of such commons (e.g., source code, articles, or documentation) have been widely explored. However, other types of contribution whose focus is directed toward the community have remained significantly less visible (e.g., the organization of events or mentoring). This work challenges the notion of contribution in peer production through an in-depth qualitative study of a prominent “code-centric” example: the case of the free software project Drupal. Involving the collaboration of more than a million participants, the Drupal project supports nearly 2% of websites worldwide. This research (1) offers empirical evidence of the perception of “community-oriented” activities as contributions, and (2) analyzes their lack of visibility in the digital platforms of collaboration. Therefore, through the exploration of a complex and “code-centric” case, this study aims to broaden our understanding of the notion of contribution in peer production communities, incorporating new kinds of contributions customarily left invisible.Item Analysis of the Potentials of Blockchain for the Governance of Global Digital Commons(Frontiers in Blockchain, 2021) Rozas Domingo, David; Tenorio Fornés, Ámbar; Hassan Collado, SamerIn recent years, the increasing need for global coordination has attracted interest in the governance of global-scale commons. In the current context we observe how online applications are ubiquitous, and how emerging technologies enable new capabilities while reshaping sectors. Thus, it is pertinent to ask: could blockchain technologies facilitate the extension and scaling up of cooperative practices and commons management in this global context? In order to address this question, we propose a focus on the most paradigmatic and widely successful examples of global cooperation: non-rival global commons. Examples of these are the digital resources maintained by large peer production communities, such as free/libre open source software and Wikipedia. Thus, this article identifies and analyses the potentialities of blockchain to support the sustainability and management of non-rival global commons. Our approach draws on Elinor Ostrom’s classic principles for commons governance, although revisiting and adapting these to the more challenging scope of global commons. Thus, in this work we identify the affordances which blockchain provides (e.g. tokenisation, formalisation of rules, transparency or codification of trust) to support the effective management of this type of global commons based on these adapted Ostrom principles. As part of our analysis, we provide numerous examples of existing blockchain projects using affordances in line with each principle, as well as potential integrations of such affordances in existing practices of CBPP communities. Our analysis shows that, when considering the challenges of managing global commons (e.g. heterogeneity or scale), the potential of blockchain is particularly valuable to explore solutions that: distribute power, facilitate coordination, scale up governance, visibilise traditionally invisible work, monitor and track compliance with rules, define collective agreements, and enable cooperation across communities. These affordances and the subsequent analysis contribute to the emergent debate on blockchain-based forms of governance, first by providing analytical categories for further research, but also by providing a guide for experimentation with the development of blockchain tools to facilitate global cooperation.Item Scanning the European Ecosystem of Distributed Ledger Technologies for Social and Public Good: What, Why, Where, How, and Ways to Move Forward(2020) Hassan Collado, Samer; Brekke, Jaya Klara; Atzori, Marcella; Bodó, Balázs; Meiklejohn, Sarah; De Filippi, Primavera; Beecroft, Kate; Rozas Domingo, David; Orgaz Alonso, Sergio Christian; Martínez Vicente, Elena; López Morales, Genoveva; Figueras Aguilar, Abel; Roque Mendes Pólvora, Alexander, ed.; Hakami, Anna, ed.; Bol, Erica, ed.Distributed Ledger Technologies (DLTs), such as blockchains, are primarily tamper-resistant and time-stamped databases. They allow multiple parties to record, verify and share data on a peer-to-peer basis across a network, in decentralised, synchronised and transparent ways, with limited human intervention and reduced intermediate steps. These technologies are mostly known for business use cases, from cryptocurrencies to asset track and tracing. But there are numerous organisations nowadays searching for alternative ways to harness the potential of DLTs in the pursuit of public and social good, from local to global challenges, and towards more inclusive, cooperative, sustainable, ethical or accountable digital and physical worlds. This Science for Policy report explores the current status of this particular field both theoretically and empirically, in the framework of the project #DLT4Good: Co-creating a European Ecosystem of DLTs for Social and Public Good. Part One offers a conceptual overview of the connections between main features of DLTs and their potential for social and public good goals. Emphasis is placed on different approaches to decentralisation, and on core building blocks of DLTs linked with values such as trust, privacy, self-sovereignty, autonomy, inclusiveness, transparency, openness, or the commons. Part Two comprises a scanning of the current European ecosystem of DLT projects with activities in this field. It contains a summarized version of a database published online with 131 projects, and a quantitative review of main trends. It also includes a qualitative assessment of 10 projects selected from the larger sample to showcase this field and its diversity. Part Three concludes with six independent position papers and recommendations from experts and advisors of the #DLT4Good project. The main topics addressed range from decentralized governance to collaborative economies, with highlights on issues such as trust, verifiability, transparency, privacy or bottom-up coordination.Item When Ostrom Meets Blockchain: Exploring the Potentials of Blockchain for Commons Governance(SAGE Open, 2021) Rozas Domingo, David; Tenorio Fornés, Ámbar; Díaz Molina, Silvia; Hassan Collado, SamerBlockchain technologies have generated enthusiasm, yet their potential to enable new forms of governance remains largely unexplored. Two confronting standpoints dominate the emergent debate around blockchain-based governance: discourses characterized by the presence of techno-determinist and market-driven values, which tend to ignore the complexity of social organization; and critical accounts of such discourses which, while contributing to identifying limitations, consider the role of traditional centralized institutions as inherently necessary to enable democratic forms of governance. In this article, we draw on Ostrom’s principles for self-governance of communities to explore the transformative potential of blockchain beyond such standpoints. We approach blockchain through the identification and conceptualization of six affordances that this technology may provide to communities: tokenization, self-enforcement and formalization of rules, autonomous automatization, decentralization of power over the infrastructure, increasing transparency, and codification of trust. For each affordance, we carry out a detailed analysis situating each in the context of Ostrom’s principles, considering both the potentials of algorithmic governance and the importance of incorporating communities’ social practices into blockchain-based tools to foster forms of self-governance. The relationships found between these affordances and Ostrom’s principles allow us to provide a perspective focused on blockchain-based commons governance.Item Research informing policy: an analysis of an emerging blockchain-enabled collaborative economy(Scanning the European Ecosystem of Distributed Ledger for Social and Public Good Technologies, 2020) Hassan Collado, Samer; Rozas Domingo, DavidItem Ostrom’s crypto-principles?
