The Catalan tsunami: encrypting swarm intelligence

A Mediterranean tsunami is a rare, once-in-a-century event. A black swan. In Catalonia, the abnormal surge has taken the unique form of a “Democratic Tsunami”.

On Monday 14 October, the Spanish Supreme Court sentenced 12 Catalan politicians and grassroots activists to long jail terms for sedition and misuse of public funds. Sedition laws are a thing of the past in many liberal democracies. To date, the penal category of sedition had rarely been applied in post-1978 Spain.

The Supreme Court sentence puts an end to a lengthy trial judging the failed secession bid of 1 October 2017. Yet, the harshness of the ruling, qualified by the International Commission of Jurists as “disproportionate and ultimately unjustifiable” also marks the start of a new wave of pro-independence, pro-human rights activism and protest in Catalonia.


Stop repression in Catalonia, by Steve Eason (Flikr)

The Democratic Tsunami emerged a few weeks ago as a grassroots activist initiative to prepare “the citizens’ response to the Supreme Court sentence”. As with other digital-born activist movements, Democratic Tsunami thrives on social media platforms. Especially on Telegram, Catalonia’s hottest messaging app. In a matter of days, the Democratic Tsunami Telegram channel has grown from a few thousand to nearly 330,000 subscribers at the time of writing.

Democratic Tsunami deploys activism tactics mirroring some of the nimble forms of ongoing protest in Hong Kong. Among them, a leaderless online presence to preserve anonymity; unidirectional communications via “official” channels to discourage fake accounts; short-notice, bullet-point calls for people to pop up in local meetups (or “picnics”). With these tools, activists have coordinated large sit-ins at Hong Kong and Barcelona international airports.


Underpinning these tactics, Democratic Tsunami activists leverage encrypted, privacy-enhanced technologies. This week, the group has released an app that requires a QR code to open. Users can only get the code from other users within their “trusted circles” and are expected to share it likewise. The app requests users to share their approximate location and time preferences to “know how many people are available in each area and when available for peaceful actions of civil disobedience”. Notifications will only pop up for those people within the area.

The new generation of activists is as tech-savvy as their immediate predecessors of the Umbrella Revolution, the Spanish 15-M movement, or the 2017 independence referendum in Catalonia, to name well-known examples. Yet, both Hong Kong and Catalan activists have grown weary of exposing their identities in a world where state surveillance, data (and metadata) breaches and engineered misinformation are the new normal.

The new layer of decentralised, encrypted protocols may offer greater resistance to surveillance, censorship, and hacking. But, as many blockchain projects show – to mention a technology where full decentralisation is the Holy Grail – architectural decentralisation does not necessarily entail decentralised governance. In fact, there is an interesting paradox here, for decentralised, trustless governance requires first and second-order levels of trust: (i) trust the code, (ii) trust the [team of] coders. If coders remain anonymous for strategic reasons, second-order trust becomes a leap of faith (we trust you, whoever you are). The suspension of disbelief to allow centralised management of collective intelligence is a new form of “swarm activism” in political conflict scenarios. A digital social contract with a post-modern, encrypted Leviathan. Perhaps a sophisticated “human botnet”, as Enric Luján has recently argued on Twitter.

Will it work for the Democratic Tsunami? In the thick of another complex cycle of protests, demands and repression, it is too early to call. Stay tuned.

Linked democracy: Foundations, Tools, and Applications

Citizens’ trust in democratic institutions is reaching new lows globally. The trust deficit primarily affects governments and representative institutions, but also media outlets and platforms spreading misinformation. In parallel, new forms of digital populism—bots, fake news, micro-targeting—are on the rise, degrading public debate and disempowering citizens and their voices. In the age of social media, paradoxically, citizens’ isegoria—the equal right to participate in the public debate—could come to an end.

LinkedDemocracyYet, these trends also coexist with ongoing experimenting and testing of innovative tools and strategies for civic action, such as crowdsourced data curation, deliberation, or decision making. A new generation of civic technologies is now enabling citizens to blend offline and online resources to achieve new goals and reinvent democracy in the 21st century. The interplay between people, civic technologies and open data can create participatory ecosystems where collective knowledge emerges and further civic action develops. Our book examines these formations as ‘linked democracy ecosystems’ and analyses their emergence and governing principles.

Sac i sort: vells i nous models de democràcia aleatòria

La tria aleatòria de ciutadans per ocupar diferents càrrecs i responsabilitats polítiques era un dels trets característics de la democràcia atenenca clàssica. Què suscita l’interès contemporani per la democràcia aleatòria i pel disseny d’institucions basades en el principi d’aleatorietat?

Apunts breus sobre la democràcia a Europa: reptes i sortides

L’escenari polític europeu s’ha vist sacsejat amb la irrupció de partits i discursos d’arrel populista que impugnen principis i valors democràtics i laminen les institucions representatives arreu del continent. Però, és aquesta, realment, l’única resposta possible a la creixent apatia electoral i a la desconfiança en les institucions? La Unió Europea té al davant el gran repte de dissenyar institucions que articulin les capacitats polítiques de la ciutadania en tots els nivells, i construir així un veritable demos europeu. Perquè, en definitiva, sense més democràcia no hi haurà més Europa.

Is Blockchain Hashing an Effective Method for Electronic Governance?

My paper with Oleksii Konashevych on the use of the blockchain for e-governance is now published. Check out the online version at:


Governments across the world are testing different uses of the blockchain for the delivery of their public services. Blockchain hashing–or the insertion of data in the blockchain–is one of the potential ablockchain-3012026_640pplications of the blockchain in this space. With this method, users can apply special scripts to add their data to blockchain transactions, ensuring both immutability and publicity. Blockchain hashing also secures the integrity of the original data stored on central governmental databases. The paper starts by analysing possible scenarios of hashing on the blockchain and assesses in which cases it may work and in which it is less likely to add value to a public administration. Second, the paper also compares this method with traditional digital signatures using PKI (Public Key Infrastructure) and discusses standardisation in each domain. Third, it also addresses issues related to concepts such as “distributed ledger technology” and “permissioned blockchains.” Finally, it raises the question of whether blockchain hashing is an effective solution for electronic governance, and concludes that its value is controversial, even if it is improved by PKI and other security measures. In this regard, we claim that governments need first to identify pain points in governance, and then consider the trade-offs of the blockchain as a potential solution versus other alternatives.

Distributed, privacy-enhancing technologies in the 2017 Catalan referendum on independence: New tactics and models of participatory democracy

My paper on how civic groups leveraged distributed technologies in the 2017 Catalan referendum on independence is now available at First Monday.


This paper examines new civic engagement practices unfolding during the 2017 referendum on independence in Catalonia. These practices constitute one of the first signs of some emerging trends in the use of the Internet for civic and political action: the adoption of horizontal, distributed, and privacy-enhancing technologies that rely on P2P networks and advanced cryptographic tools.

2017 Catalan referendum on independence, by HazteOir

In this regard, the case of the 2017 Catalan referendum, framed within conflicting political dynamics, can be considered a first-of-its-kind in participatory democracy. The case also offers an opportunity to reflect on an interesting paradox that twenty-first-century activism will face: the more it will rely on private-friendly, secured, and encrypted networks, the more open, inclusive, ethical, and transparent it will need to be.

Assigning Creative Commons Licenses to Research Metadata: Issues and Cases

Check out our new book chapter discussing licensing options for research metadata:

Pre-print available here:


This paper discusses the problem of lack of clear licensing and transparency of usage terms and conditions for research metadata.
2000px-Cc-by_new.svg_ Making research data connected, discoverable and reusable are the key enablers of the new data revolution in research. We discuss how the lack of transparency hinders discovery of research data and make it disconnected from the publication and other trusted research outcomes. In addition, we discuss the application of Creative Commons licenses for research metadata, and provide some examples of the applicability of this approach to internationally known data infrastructures.
