Steelhead: Interleaving Partially Synchronous and Asynchronous Commit Rules on a Shared DAG
George Danezis, Zeno De Angeli, Philipp Jovanovic +3
Dual-mode consensus protocols are fast when the network is partially synchronous and remain live under asynchrony. We introduce Steelhead, a dual-mode mechanism that composes a par…
Hydrozoan: Latency-Adaptive DAG Consensus under Mixed Byzantine and Crash Faults
Qianyu Yu, Lefteris Kokoris-Kogias, Alberto Sonnino
DAG-based consensus protocols can achieve great throughput and the optimal three-message-delay limit for n = 3f+1 consensus. While two-delay protocols exist, they pay with reduced…
Barnacle: Adaptive Multi-Leader Scheduling for DAG-Based Consensus
George Danezis, Zeno De Angeli, Alexandru Ianov Vitanov +5
In DAG-based consensus, all validators propose blocks concurrently, and designated leader blocks drive transaction commit. Having multiple leader slots per round cuts queuing laten…
Orcaella: Hybrid Fault Tolerance with Client-Selectable Finality Latency
Lefteris Kokoris-Kogias, Alberto Sonnino
Classical partially synchronous state machine replication, as in PBFT, tolerates f Byzantine replicas among n at least 3f+1 using three communication steps per request. Recent prot…
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…
Sedna: Sharding transactions in multiple concurrent proposer blockchains
Alejandro Ranchal-Pedrosa, Benjamin Marsh, Lefteris Kokoris-Kogias +1
Modern blockchains increasingly adopt multi-proposer (MCP) consensus to remove single-leader bottlenecks and improve censorship resistance. However, MCP alone does not resolve how…
