Concentration Within Distribution: Unmasking Bitcoin's Structural Centralization Through Network Science
Myriam Nonaka, F. Javier Marín-Rodríguez, Alexander Jiricny +4
We construct the Bitcoin User Network (BUN) directly from raw blockchain data up to late 2025, which allows us to explore its mesoscopic properties and trace its temporal evolution…
Fully personalized PageRank and algebraic methods to distribute a random walker
Gonzalo Contreras-Aso, Regino Criado, Miguel Romance
We present a comprehensive analysis of algebraic methods for controlling the stationary distribution of PageRank-like random walkers. Building upon existing literature, we compile…
On the application of Visibility Graphs in the Spectral Domain for Speaker Recognition
Hernan Bocaccio, Sergio Iglesias-Pérez, Miguel Romance +2
In this study, we explore the potential of visibility graphs in the spectral domain for speaker recognition. Adult participants were instructed to record vocalizations of the five…
Beyond directed hypergraphs: heterogeneous hypergraphs and spectral centralities
Gonzalo Contreras-Aso, Regino Criado, Miguel Romance
The study of hypergraphs has received a lot of attention over the past few years, however up until recently there has been no interest in systems where higher order interactions ar…
Can the PageRank centrality be manipulated to obtain any desired ranking?
Gonzalo Contreras-Aso, Regino Criado, Miguel Romance
The significance of the PageRank algorithm in shaping the modern Internet cannot be overstated, and its Complex Network theory foundations continue to be a subject of research. In…
Why are there six degrees of separation in a social network?
Ivan Samoylenko, David Aleja, Eva Primo +11
A wealth of evidence shows that real world networks are endowed with the small-world property i.e., that the maximal distance between any two of their nodes scales logarithmically…
