Tidehunter: Large-Value Storage With Minimal Data Relocation
Andrey Chursin, Lefteris Kokoris-Kogias, Alex Orlov +2
Log-Structured Merge-Trees (LSM-trees) dominate persistent key-value storage but suffer from high write amplification from 10x to 30x under random workloads due to repeated compact…

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…

Adelie: Detection and prevention of Byzantine behaviour in DAG-based consensus protocols
Andrey Chursin
Recent developments in the Byzantine Fault Tolerant consensus protocols have shown the DAG-based protocols to be a very promising technique. While early implementations of DAG-base…
