Rondo: Scalable and Reconfiguration-Friendly Randomness Beacon
Xuanji Meng
Network and Distributed System Security (NDSS) Symposium 2025 · Day 2 · Secure Protocols
In an increasingly decentralized digital landscape, the need for robust, unpredictable, and publicly verifiable randomness is paramount. This talk at NDSS25 introduces Rondo, a novel **Distributed Randomness Beacon (DRB)** protocol designed to address critical limitations in existing solutions, specifically concerning scalability and dynamic reconfiguration. Presented by Xuanji Meng from Chinhai University, Rondo offers a significant advancement in generating periodic random numbers for a wide array of decentralized applications and cryptographic protocols.
AI review
Legitimate systems security research published at NDSS — a peer-reviewed venue that filters out the noise — tackling a real problem in distributed randomness generation. The contributions are genuine: a new AVSS variant with partial output, a HotStuff extension with dynamic reconfiguration, and batched polynomial commitment optimizations that together push communication complexity below the cubic ceiling. Solid academic work, but it's a conference paper presentation, not a practitioner talk, and the summary provided reads like an auto-generated abstract rather than a window into what makes…
