Cardano's Van Rossum hard fork has upgraded the network to version 11, enhancing smart contract efficiency and shifting governance to the community.
On July 18, Cardano successfully implemented the Van Rossum hard fork, upgrading the network to protocol version 11. This upgrade is particularly notable as it was entirely approved through on-chain governance, marking a significant shift in decision-making power from the founding company, Input Output, to the community.
Key Features of the Upgrade
The Van Rossum hard fork reduces the costs associated with executing smart contracts and lays the groundwork for future scalability improvements, including the upcoming Ouroboros Leios upgrade scheduled for 2026. While the upgrade does not change the way users transact with ADA, it enhances the efficiency of smart contracts, which are vital for various decentralized applications.
The transition from version 10 to version 11 took place during epoch 644, following a ratification vote on July 13. The governance process involved three bodies, with delegated representatives voting 78.97% in favor of the proposal, surpassing the required 60% threshold. The constitutional committee unanimously approved the changes, while pool operators narrowly backed the hard fork with 53.02% support.
For the upgrade to be validated, at least 85% of stake pools needed to run compatible node software. Reports indicated that about 93% of block production had already adopted version 11 prior to the hard fork's activation.
Technical Aspects of Version 11
This version is classified as an intra-era hard fork, meaning it operates within the existing governance framework without altering transaction structures, thus making the upgrade process smoother. It introduces improvements to Plutus, Cardano's smart contract platform, ensuring consistent functionality across different versions and enabling older applications to utilize new features.
The upgrade also strengthens validation rules within the ledger, including a rule that prohibits the reuse of cryptographic identity keys among multiple stake pools. According to Input Output, this upgrade is foundational for the forthcoming Dijkstra era hard fork, which will integrate the Ouroboros Leios scaling proposal, aiming to significantly boost transaction throughput while maintaining security standards.
Impact on Cardano Users
For everyday ADA holders, there are no immediate changes to how they manage or transact with their tokens. Current transactions remain unchanged, and no updates to wallets are necessary. However, the benefits of the upgrade will become apparent as new decentralized applications are developed, with lower operational costs for smart contracts potentially leading to reduced transaction fees for users.
The Van Rossum hard fork also signals a shift in governance within the Cardano ecosystem. Unlike many blockchains where a central team directs development, this upgrade illustrates that Cardano's stakeholders can independently influence protocol changes. This empowers ADA investors, allowing them to play a more active role in the network's evolution, contrasting with the previous model of centralized governance.
Looking ahead, the Leios upgrade promises to enhance transaction processing capabilities significantly, providing faster confirmations and increased capacity during peak usage, thereby improving the overall user experience on the Cardano network.
