Asymmetric Grid Quorum Systems for Heterogeneous Processes
Michael Senn, Christian Cachin
Quorum systems are a common way to formalize failure assumptions in distributed systems. Traditionally, these assumptions are shared by all involved processes. More recently, syste…
A Lightweight Approach for State Machine Replication
Christian Cachin, Jinfeng Dou, Christian Scheideler +1
We present a lightweight solution for state machine replication with commitment certificates. Specifically, we adapt and analyze a median rule for the stabilizing consensus problem…
Weaker Assumptions for Asymmetric Trust
Ignacio Amores-Sesar, Christian Cachin, Simon Holmgaard Kamp +1
In distributed systems with asymmetric trust, each participant is free to make its own trust assumptions about others, captured by an asymmetric quorum system. This contrasts with…
DAG-based Consensus with Asymmetric Trust [Extended Version]
Ignacio Amores-Sesar, Christian Cachin, Juan Villacis +1
In protocols with asymmetric trust, each participant is free to make its own individual trust assumptions about others, captured by an asymmetric quorum system. This contrasts with…
