Cardano just crossed a milestone that has nothing to do with price charts. The Van Rossem hard fork went live on July 18, 2026, at approximately 21:44 UTC, pushing the network to Protocol Version 11 and, more importantly, proving that its community governance system actually works in production.
The upgrade cuts smart contract execution costs, introduces new built-in functions for the Plutus development framework, and updates the network’s cost model. ADA responded with a roughly 5% price bump following activation, outperforming the broader crypto market.
What the Van Rossem hard fork actually changes
The core of this hard fork targets Plutus, Cardano’s smart contract framework. The upgrade adds new built-in functions to Plutus, and the cost model, which determines how much computational resources smart contracts consume, has also been updated. In practical terms, running apps on Cardano just got cheaper.
Node security also received enhancements. This was the first hard fork ratified entirely through Cardano’s Voltaire governance framework. The ratification happened on July 13, 2026, following a four-week decision period. The final tally showed 68.57% DRep support, clearing the threshold needed to proceed. DReps, or Delegated Representatives, are Cardano’s version of elected governance participants, holders who either vote directly or delegate their voting power to representatives they trust.
