motion 295 is now up for vote. The motion proposes the cancellation of 115 slashes that happened in era 2,249.
v9010 runtime upgrade introduced some changes to elections to ensure redundancy in the case that a solution did not get submitted to the chain. Validators running with Interpreted wasm execution, slower hardware, and / or older client releases were not able to process election solutions within a bounded time window, and thus continually would try and process election solutions. This resulted in Off Chain Workers being not available to submit heartbeats, making validators that did not produce any blocks in the session offline. Enough validators were not running with proper performance (wasm execution parameters, lower end hardware, or older client versions), and as a result, exceeded the threshold for liveness slashing.
Please vote at your convenience!
