It's not a lie if you don't get caught: simplifying reconfiguration in SMR through dirty logs

Researchers have introduced 'Gauss,' a novel reconfiguration engine that treats consensus protocols as interchangeable modules. By separating a protocol's 'dirty' internal log from a sanitized external one, it allows engineers to upgrade membership, failure thresholds, and the core consensus algorithm independently. Initial evaluation on the Rialo blockchain shows this modular approach enables seamless evolution of the system stack across diverse protocols with minimal global downtime, solving a major production complexity.
