A comparative study across the most widely known blockchain technologies is conducted with a bottom-up approach. Blockchains are disentangled into building blocks. Each building block is then hierarchically classified in main and subcomponents. Then, alternative layouts for the subcomponents are...

Many community detection algorithms have been developed to uncover the mesoscopic properties of complex networks. However how good an algorithm is, in terms of accuracy and computing time, remains still open. Testing algorithms on real-world network has certain restrictions which made their...

This study covers the evolutionary development of block-chain technologies over the last 11 years (2009 — 2019) and sheds lights on potential areas of innovation in heretofore unexplored sub-components. For this purpose, we collected and analysed detailed data on 107 different block-chain...

Chinese banks have sought ways to rapidly expand lending in light of strict regulatory mandates to reduce official lending and maintain high capital adequacy ratios. Through arbitraging capital risk weights, total lending has expanded while capital adequacy ratios have remained unchanged....

Pursuit of honest and truthful decision-making is crucial for governance and accountability in democracies. However, people sometimes take different perspectives of what it means to be honest and how to pursue truthfulness. Here we explore a continuum of perspectives from evidence-based...

Excessive leverage, i.e. the abuse of debt financing, is considered one of the primary factors in the default of financial institutions. Systemic risk results from correlations between individual default probabilities that cannot be considered independent. Based on the structural framework by...
