Cardano (ADA) achieved a significant technical milestone on July 18, 2026, when the network activated the Van Rossem hard fork at 21:44:51 UTC, marking the first Cardano upgrade to be fully ratified through on-chain governance under the Voltaire framework. The upgrade moved the blockchain to Protocol Version 11 and introduced a suite of improvements designed to lower smart contract execution costs, enhance Plutus performance, and strengthen node security. Despite the technical achievement, ADA price action has remained subdued, trading near $0.16 as the broader market awaits confirmation of a sustained breakout.
