This theoretical review analyses digital nationalism in Catalonia. It describes the context of the confrontation between the pro- independence movement and the Spanish government. This confrontation is characterised by a paradigm dominated by negotiations, mobilisations, and repression, which eventually led to the 2017 independence referendum. The failure of the independence process led grassroots groups and major parties to develop original digital strategies. Whilst grassroots groups relied on digital tools to organise spectacular protests, the Junts per Catalunya (Together for Catalonia) party and the Consell de la República (Council of the Republic) organisation promoted the República Digital (Digital Republic) project. The study frames Catalan nationalism in relation to previous research on digital nationalism. It underlines how, in terms of actors involved and ideologies promoted, the Catalan secessionist project does not fit into models described by the academic literature about digital nationalism. Furthermore, this research analyses how the Digital Republic has been articulated by Catalan institutions and nationalist organisations in order to create a “virtual state”. Finally, the study discusses the Digital Republic as a strategy to avoid direct confrontation with the Spanish authorities and its attempt to create a “digital surrogate” to independence.

“…Self-Sovereign Identity (SSI) is a cornerstone of Web 3.0 [10], as it represents an innovative approach to digital identity management that aims to remove dependency on centralized third parties and focuses on autonomy and ownership by individuals. These identities are verified and recognized by different organizations and online services, allowing users to interact securely and privately without having to reveal sensitive information.…”

“…The emergence of blockchain technology [9] and of the concept of Self-Sovereign Identity (SSI) [10,11] provide individuals with new ways to manage their own data, including competencies. These technologies make it possible to create verifiable and immutable digital records that can be inspected by multiple parties while respecting privacy and without giving up control to a single organisation; rather, data are fully distributed and decentralised.…”

Management of competencies is a crucial concern for both learners and workers as well as for training institutions and companies. For the former, it allows users to track and certify the acquired skills to apply for positions; for the latter, it enables better organisation of business processes. However, currently, most software systems for competency management adopted by the industry are either organisation-centric or centralised: that is, they either lock-in students and employees wishing to export their competencies elsewhere, or they require users’ trust and for users to give up privacy (to store their personal data) while being prone to faults. In this paper, we propose a user-centric, fully decentralised competency management system enabling verifiable, secure, and robust management of competencies digitalised as Open Badges via notarization on a public blockchain. This way, whoever acquires the competence or achievement retains full control over it and can disclose his/her own digital certifications only when needed and to the extent required, migrate them across storage platforms, and let anyone verify the integrity and validity of such certifications independently of any centralised organisation. The proposed solution is based on C-Box®, an existing application for the management of digital competencies that has been improved to fully support models, standards, and technologies of the so-called Web 3.0 vision—a global effort by major web organisations to “give the web back to the people”, pushing for maximum decentralisation of control and user-centric data ownership.

“…As the use case of inverse transparency is specifically tailored to the companyinternal context, we therefore show how to integrate an institutional IdP for identity verification. To minimize the risk of confidentiality attacks, we apply the concept of self-sovereign identity [see, e.g., 49,64]. That means that each party is issued a verifiable credential [79] from the IdP, which it can present to exchange participants directly.…”

Employee data can be used to facilitate work, but their misusage may pose risks for individuals. Inverse transparency therefore aims to track all usages of personal data, allowing individuals to monitor them to ensure accountability for potential misusage. This necessitates a trusted log to establish an agreed-upon and non-repudiable timeline of events. The unique properties of blockchain facilitate this by providing immutability and availability. For power asymmetric environments such as the workplace, permissionless blockchain is especially beneficial as no trusted third party is required. Yet, two issues remain: (1) In a decentralized environment, no arbiter can facilitate and attest to data exchanges. Simple peer-to-peer sharing of data, conversely, lacks the required non-repudiation. (2) With data governed by privacy legislation such as the GDPR, the core advantage of immutability becomes a liability. After a rightful request, an individual’s personal data need to be rectified or deleted, which is impossible in an immutable blockchain. To solve these issues, we present Kovacs , a decentralized data exchange and usage logging system for inverse transparency built on blockchain. Its new-usage protocol ensures non-repudiation, and therefore accountability, for inverse transparency. Its one-time pseudonym generation algorithm guarantees unlinkability and enables proof of ownership, which allows data subjects to exercise their legal rights regarding their personal data. With our implementation, we show the viability of our solution. The decentralized communication impacts performance and scalability, but exchange duration and storage size are still reasonable. More importantly, the provided information security meets high requirements. We conclude that Kovacs realizes decentralized inverse transparency through secure and GDPR-compliant use of permissionless blockchain.
