Leios scaling threatens Cardano stability unless fast path passes

Leios scaling threatens Cardano stability unless fast path passes

Summary

Kevin Hammond proposed a Cardano governance fast path to disable Leios during a severe network problem by setting an endorser-block transaction limit to zero. The change would waive notice and timing limits for shutdown, but retain required votes and enactment across at least one epoch boundary; reactivation would follow normal rules. The proposal depends on confirmation that zero reliably stops Leios activity, test-network exercises and consistent support across node implementations. It also conflicts with CAP-12 version 5, which expressly bars zero-valued parameters, so the constitutional text would need revision. Leios remains under development: DijkstraNet did not yet have full implementation, while early integration testing was underway on Musashi.
