A Secure Sequencer and Data Availability Committee for Rollups (Extended Version)
Margarita Capretto, MartÃn Ceresa, Antonio Fernández Anta +2
Blockchains face a scalability limitation, partly due to the throughput limitations of consensus protocols, especially when aiming to obtain a high degree of decentralization. Laye…
Is Synthetic Image Augmentation Useful for Imbalanced Classification Problems? Case-Study on the MIDOG2025 Atypical Cell Detection Competition
Leire Benito-Del-Valle, Pedro A. Moreno-Sánchez, Itziar Egusquiza +4
The MIDOG 2025 challenge extends prior work on mitotic figure detection by introducing a new Track 2 on atypical mitosis classification. This task aims to distinguish normal from a…
A Design Framework for operationalizing Trustworthy Artificial Intelligence in Healthcare: Requirements, Tradeoffs and Challenges for its Clinical Adoption
Pedro A. Moreno-Sánchez, Javier Del Ser, Mark van Gils +1
Artificial Intelligence (AI) holds great promise for transforming healthcare, particularly in disease diagnosis, prognosis, and patient care. The increasing availability of digital…
A Decentralized Sequencer and Data Availability Committee for Rollups Using Set Consensus
Margarita Capretto, MartÃn Ceresa, Antonio Fernández Anta +2
Blockchains face a scalability challenge due to the intrinsic throughput limitations of consensus protocols and the limitation in block sizes due to decentralization. An alternativ…
Lite-PoT: Practical Powers-of-Tau Setup Ceremony
Lucien K. L. Ng, Pedro Moreno-Sanchez, Mohsen Minaei +3
Zero-Knowledge Succinct Non-Interactive Argument of Knowledge (zk-SNARK) schemes have gained significant adoption in privacy-preserving applications, decentralized systems (e.g., b…
DTL: Data Tumbling Layer. A Composable Unlinkability for Smart Contracts
Mohsen Minaei, Pedro Moreno-Sanchez, Zhiyong Fang +5
We propose Data Tumbling Layer (DTL), a cryptographic scheme for non-interactive data tumbling. The core concept is to enable users to commit to specific data and subsequently re-u…
