Complexity Science Hub

Complexity Science Hub We Are Europe's Research Center Translating Data into Solutions for a Better World.

The Complexity Science Hub (CSH) is Europe’s research center for the study of complex systems. We derive meaning from data from a range of disciplines – economics, medicine, ecology, and the social sciences – as a basis for actionable solutions for a better world. Established in 2016, we have grown to over 70 researchers, driven by the increasing demand to gain a genuine understanding of the networks that underlie society, from healthcare to supply chains. Through our complexity science approaches linking physics, mathematics, and computational modeling with data and network science, we develop the capacity to address today's and tomorrow’s challenges. CSH members are AIT Austrian Institute of Technology, BOKU University, Central European University CEU, Graz University of Technology, IT:U Interdisciplinary Transformation University Austria, Medical University of Vienna, TU Wien, University of Continuing Education Krems, Vetmeduni Vienna, Vienna University of Economics and Business, and WKO Austrian Economic Chambers.

💸 𝗔𝗿𝗲 𝗰𝗿𝘆𝗽𝘁𝗼 𝗵𝗮𝗰𝗸𝘀 𝗿𝗲𝗮𝗹𝗹𝘆 𝗮𝗯𝗼𝘂𝘁 𝘁𝗵𝗲 𝗺𝗼𝗻𝗲𝘆 𝘁𝗵𝗮𝘁 𝗴𝗲𝘁𝘀 𝘀𝘁𝗼𝗹𝗲𝗻? Cryptocurrency investment has surged enormously in popularity. For example, CoinLedger estimates that more than 560 million people worldwide now hold digital assets. This rapid growth, however, has been accompanied by a rise in hacking incidents and substantial financial losses.

Reports on crypto cyberattacks often focus on the funds that disappear immediately. But new research shows that this is only part of the story. An analysis by Complexity Science Hub researchers Stefan Kitzler and Bernhard Haslhofer, together with Masarah Paquet-Clouston, examined 22 major cyberattacks in the crypto sector between 2020 and 2022.

In 12 of these cases, the affected tokens experienced significant price crashes. While the direct losses in these cases amounted to around USD 454 million, the indirect losses due to declining token values reached USD 1.3 billion.

𝗠𝗼𝗿𝗲 𝗶𝗻𝘀𝗶𝗴𝗵𝘁𝘀:
📉 After an attack, affected tokens lost 14% of their value on average
📊 Trading volume increased in around 68% of the cases
🔍 Market reactions in DeFi resemble those in traditional finance, but are more pronounced

Join our CSH 👋
There are many uncertainties about what work will look like in the future: 🤔
What will fundamentally change through AI? 🤖 Which jobs will disappear, which new ones will emerge? Who will be able to adapt? And which cities are best positioned to embrace the coming changes? 🌆

These questions – and many more – are at the core of our upcoming Winter School at the Complexity Science Hub, led by Frank Neffke, Ljubica Nedelkoska, Xiangnan Feng, and Hillary Vipond. ❄️📚

We look forward to many highlights – including a keynote by James Evans and lectures from Maria del Rio-Chanona and Johannes Wachs. 🎤✨

And for a little holiday science magic: the size and shape of a city matter – not just for Santa’s travel routes and the energy his reindeer need 😉. With our CSH Cities Morphology visualization, you can create virtual cities based on characteristics like city shape, population, and density, and explore how these features influence travel paths, energy use, and land consumption.

🏛️ Why do we live today – and, from an evolutionary perspective, only recently – almost exclusively organized in large states? Last week, Peter Turchin and Jenny Reddish shared their insights at a special event at the Complexity Science Hub.

Peter Turchin discussed The Great Holocene Transformation, exploring how humans grew from scattered bands of foragers into vast empires in just ten millennia. He shared a paradoxical insight: war made us cooperative ⚔️🤝. From cavalry 🐎 to metalworking ⚒️, conflict forged our ultrasociality.

Jenny Reddish focused on moralizing religions – gods who reward good behavior and punish wrongdoing 🙏⚖️ – which are also a relatively recent phenomenon in human history. She offered insights into a chicken-and-egg question 🐔🥚: Did moralizing gods enable humans to live together in large states by fostering trust and cooperation in vast, anonymous societies? Or did large, complex states come first, creating the social structures in which such religions could effectively operate?

For those interested in exploring these topics further, here are the researchers’ books 📚:
