Cardano has marked a significant milestone in its development journey with the activation of the “Van Rossem” V11 hard fork on the Preview testnet. This critical move sets the stage for a pivotal mainnet upgrade, due for a vote at the end of the month. As testing continues, Cardano’s PreProd environment undergoes meticulous final checks to ensure a seamless transition to the mainnet.
What does the V11 upgrade bring?
The coordination group for Cardano, Intersect, announced that the V11 hard fork is now live on the Preview testnet. This activation follows a governance proposal launched on May 8. It offers developers a chance to test and refine smart contracts and new features in a structured setting.
The V11 upgrade comes with improvements, including faster, cost-efficient smart contract operations and enhanced stake pool security. Intersect commented on these advancements, emphasizing the cost-effectiveness and security upticks within the Cardano network.
Simultaneously, the Preview testnet is a sandbox scenario for future governance protocols, with teams observing system performance to gauge deployment readiness.
What are the ongoing steps in the PreProd phase?
As part of ongoing processes, the PreProd phase has not concluded. On May 16, an update to the Plutus Cost Model was implemented, urging developers to reassess their setups in preparation for the mainnet integration.
While PreProd operations are documented on-chain, the Hard Fork Working Group is addressing unresolved issues, chiefly those connected to the Ogmios infrastructure, before granting final approval. Collaborative efforts among the Cardano community and engineers are essential for a smooth transition.
The readiness of network components remains a focal point, with ongoing weekly meetings ensuring preparations are on track for the upcoming vote.
Key points from the article include:
- The V11 node software version is crucial for the hard fork transition.
- Final compatibility checks are tied to the DB-Sync v13.7.0.5 release.
- Fixes for service-linked issues in the PreProd phase are underway.
Cardano is gearing up to reveal the detailed schedule for the Plutus Cost Model update ahead of the mainnet vote set for May 29. The upcoming release of performance data aims to confirm the network’s preparedness for this significant upgrade. The timeline, under scrutiny, is subject to change following the final validation processes.
This upgrade pays tribute to Max van Rossem, a notable figure in the Cardano community, underlining his contributions to the project’s governance evolution.
