Beluga: Block Synchronization for BFT Consensus Protocols
Tasos Kichidis, Lefteris Kokoris-Kogias, Arun Koshy +4
Modern high-throughput BFT consensus protocols use streamlined push-pull mechanisms to disseminate blocks and keep happy-path performance optimal. Yet state-of-the-art designs lack…

Mysticeti: Reaching the Limits of Latency with Uncertified DAGs
Kushal Babel, Andrey Chursin, George Danezis +5
We introduce Mysticeti-C, the first DAG-based Byzantine consensus protocol to achieve the lower bounds of latency of 3 message rounds. Since Mysticeti-C is built over DAGs it also…

Obelia: Scaling DAG-Based Blockchains to Hundreds of Validators
George Danezis, Lefteris Kokoris-Kogias, Alberto Sonnino +1
Obelia improves upon structured DAG-based consensus protocols used in proof-of-stake systems, allowing them to effectively scale to accommodate hundreds of validators. Obelia imple…
