Cardano Activates Van Rossem Hard Fork to Lower Transaction Fees and Prepare for Major Scalability Upgrade
The update reduces smart contract execution costs and sets the stage for Ouroboros Leios later this year.

The Cardano blockchain has successfully activated its latest major technical upgrade, the Van Rossem hard fork. This update introduces key optimizations aimed at reducing smart contract execution costs while establishing the technical foundation for Ouroboros Leios, a highly anticipated scalability upgrade scheduled for release later this year.
By lowering the computational resources required to run decentralized applications, the update makes the cryptocurrency network more cost-effective for developers and end-users alike. This optimization is particularly crucial for complex decentralized finance (DeFi) protocols that require multiple smart contract interactions.
The activation of the Van Rossem hard fork represents another step in Cardano’s multi-phase development roadmap. It follows the landmark Chang hard fork, which initiated the transition toward decentralized community governance. While the previous milestone focused on democratic decision-making, the current phase prioritizes technical efficiency and network throughput.
The upcoming Ouroboros Leios upgrade is expected to dramatically increase the transaction processing capacity of the network. By separating transaction validation from block generation, Leios aims to achieve higher throughput without compromising the decentralized nature of the network. Reducing smart contract execution costs now ensures that the platform can handle the increased volume of decentralized applications expected after the scalability upgrade goes live.
