Cardano has reached a major milestone because the van Rossem arduous fork takes a step nearer to mainnet launch.
Based on Intersect, a member-based group within the Cardano ecosystem, the van Rossem arduous fork has been submitted to the preview take a look at community.

Cardano Node model 11.0.1 Pre-Launch, an important requirement to securely cross the arduous fork, has additionally gone reside, with SPOs, DApps and builders on preview urged to improve as quickly as doable.
Node 11.0.1 is thought to be the primary node launch to help the Cardano intra-era arduous fork, enabling the improve to protocol model 11 as soon as the arduous fork governance motion has been voted on by the SPOs, DReps, the Constitutional Committee and enacted on-chain.
The discharge additionally bumps cardano-api and cardano-cli to their 11.0 collection and advances the experimental arduous fork goal to protocol model 12, amongst different enhancements.
Cardano Van Rossem arduous fork
The van Rossem intra-era arduous fork will improve Cardano preview to Protocol Model 11. As a part of the improve, the Cardano mainnet protocol will probably be upgraded to Main Model 11 and Minor Model 0. Because the ledger stays within the Conway period, there wouldn’t be an period transition.
Protocol Model 11 bundles a centered set of enhancements to Plutus efficiency, ledger consistency, and node-level safety right into a single intra-era improve. Provided that it’s an intra-era arduous fork, transaction form doesn’t change and ecosystem improve effort is minimized.
A number of new Plutus primitives will probably be accessible following the improve, as outlined in CIP-0109, CIP-0132, CIP-0133, CIP-0138 and CIP-0153.
The improve unifies the set of built-in features throughout Plutus V1, V2 and V3. The complete set of built-ins (together with these launched) will turn out to be accessible throughout all Plutus language variations following the arduous fork, increasing the capabilities of present Plutus V1 and V2 scripts.
Consistent with the Cardano Structure, a minimum of 85% of stake swimming pools by lively stake ought to have upgraded to a model of the node that may help protocol model 11 earlier than ratification of this governance motion.
