FAIR+S: A validation study of a framework for sustainable research data and software
Danila Valko, Jan Sören Schwarz, Jorge Marx Gómez +1
The FAIR principles (Findable, Accessible, Interoperable, Reusable) have transformed research data management, but they do not address the environmental impact of creating and usin…
Shared Channel Capacity and Node Lifetime: An Empirical Study of the Lightning Network
Danila Valko, Jorge Marx Gómez
The Lightning Network (LN) is a rapidly evolving payment channel network that enables scalable, off-chain transactions on top of Bitcoin. While prior research has documented its to…
mosaiks are made of tesserae: GUI design for a co-simulation framework
Eike Schulte, Jan Sören Schwarz, Malte Stomberg +3
In a mosaic, a tessera is a single stone. We introduce tesserae for the co-simulation framework mosaik, where they are sets of entities. They allow for a visual, intuitive, and yet…
Topological and Temporal Stability Analysis of the Lightning Network
Danila Valko, Jorge Marx Gómez, Jorge Marx Gómez
The Lightning Network (LN) is the most prominent payment channel network built atop Bitcoin, designed to enable scalable, low-cost off-chain transactions. Understanding its structu…
Outperforming Dijkstra on Sparse Graphs: The Lightning Network Use Case
Danila Valko, Rohan Paranjpe, Jorge Marx Gómez
Efficient routing is critical for payment channel networks (PCNs) such as the Lightning Network (LN), where most clients currently rely on Dijkstra-based algorithms for payment pat…
Sustainable broadcasting in Blockchain Networks with Reinforcement Learning
Danila Valko, Daniel Kudenko
Recent estimates put the carbon footprint of Bitcoin and Ethereum at an average of 64 and 26 million tonnes of CO2 per year, respectively. To address this growing problem, several…
