Cardano Node 10.7.0 Pre-Release Launches — Van Rossem Hard Fork Enters Final Phase
Cardano Node 10.7.0 pre-release dropped on March 31, 2026, marking the start of final integration testing before the Van Rossem hard fork activates on mainnet. The release bundles UTXO-HD, KES Agent, and Cardano-RPC, alongside five new Plutus built-ins — including BLS12-381 MSM for native ZK proof verification.
Cardano Node 10.7.0 pre-release dropped on March 31, 2026, marking the start of the final integration testing phase before the Van Rossem hard fork activates on mainnet. Node 10.7.0 is one of two required software versions for Protocol Version 11, and its pre-release signals to stake pool operators (SPOs) and dApp developers to begin testing immediately. A dedicated SPO coordination call is scheduled for April 2, 2026 at 13:00 UTC.
The release bundles three significant infrastructure improvements: UTXO-HD, which moves ledger state from RAM to on-disk storage and lowers hardware requirements for node operators; KES Agent, which improves key evolution security; and Cardano-RPC, a new RPC interface for easier node interaction. These sit alongside Protocol 11's five new Plutus built-ins covering array types, cryptographic operations, and BLS12-381 multi-scalar multiplication.
The BLS12-381 MSM built-in (CIP-133) is particularly significant: it enables efficient on-chain verification of zero-knowledge proofs natively in Plutus, creating a technical bridge between Cardano L1 and Midnight's ZK infrastructure. Mainnet activation remains conditional on SPO adoption rates reaching the required threshold and a successful governance vote, with Q2 2026 as the target window.
