Inside Cardano's 'Van Rossum' Hard Fork, and How It Matters for Users
The upgrade lowers smart contract costs and sets up a later scalability overhaul, while proving stakeholders can approve protocol changes by vote.
- On Saturday, July 18, Cardano activated its Van Rossem hard fork, moving the mainnet to protocol version 11 in the network's first upgrade ratified entirely through onchain governance.
- Unlike previous upgrades coordinated by founding firm Input Output, this change required community sign-off across three bodies; stakeholders voted 78.97% in favor, exceeding the 60% threshold.
- The upgrade adds capabilities to Plutus, the platform used to write smart contracts, and tightens ledger validation rules preventing stake pool identity key reuse; wallets and transaction fees remain unchanged.
- Trading near $0.162, ADA showed little sustained market response following the event, as short positions continue to outnumber longs despite funding rates recently turning positive at about 0.0061%.
- Laying the foundation for the Dijkstra era hard fork, this upgrade prepares Cardano for Ouroboros Leios; Input Output wrote the scaling change aims to sharply increase transaction capacity without weakening security.
