On July 18, the Van Rossem hard fork was successfully activated on the Cardano mainnet. This event marks an important step in the evolution of the blockchain — as part of the upgrade, updated Plutus pricing models came into effect, significantly reducing the computational cost of executing smart contracts. For developers, this means that creating and deploying decentralized applications (dApps) will become more accessible and cost-effective.
What has changed?
The key improvement was the introduction of new fees for executing Plutus scripts. Previously, the cost of operations was high, limiting the adoption of complex DeFi protocols and NFT marketplaces. Now, thanks to the optimization of computational processes, transaction fees should decrease, and the user experience should improve. This is especially relevant amid growing competition from other Layer-1 blockchains.
Preparing for the Dijkstra era
Beyond immediate benefits, Van Rossem serves a strategic purpose: it lays the infrastructural foundation for the next hard fork — the Dijkstra era. This upgrade will be key to scaling the network. As part of Dijkstra, the Ouroboros Leios protocol is planned to be implemented — an innovative consensus mechanism designed to dramatically increase network throughput without compromising security or decentralization.
My analysis
Given the current market situation, where high fees and low transaction speeds remain bottlenecks for many blockchains, the timely reduction of smart contract costs on Cardano is not just a technical update but a competitive advantage. If Ouroboros Leios truly delivers the claimed performance, Cardano could become a serious contender for leadership among platforms for mass DeFi solutions. However, the key factor will remain the successful implementation and timely launch of Dijkstra.
