Cardano van Rossem arduous fork information landed on the preview check community on May 5, with Intersect, the member-based group coordinating Cardano’s technical roadmap, confirming each the governance motion submission and the launch of Cardano Node model 11.0.1 Pre-Release concurrently.
The improve strikes Protocol Version 11 one step nearer to mainnet, with the vital variable now shifting completely to SPO (Stake Pool Operator) readiness: no less than 85% of stake swimming pools by energetic stake should improve earlier than ratification can proceed.

What are the 85% SPO Threshold News Triggers for Cardano
