Cardano Node 9.0.0
Node 9.0.0 is a major release of the Cardano node that contains all the changes that are needed for the Conway ledger era, including on-chain governance via CIP-1694, support for Plutus v1 reference scripts, and Plutus script signature support via CIP-69. It is recommended that all node users upgrade to this or a later version of the node.
This is the first node that can support crossing the 9.0 hard fork (Chang) boundary on mainnet and long-running testnets, such as PreProd). It only supports entering the bootstrap phase of CIP-1694 in production environments (Protocol Version 9.0) and not
the transition to enable DRep voting and all governance actions (Protocol Version 10.0).
System testing results for the 9.0.0 release can be found on the corresponding tag testing page.
No Conway Genesis File
Note that node 9.0.0 is supplied without a valid Conway-era Genesis file, which will be needed to cross the Chang hard fork. This will be supplied at a later date, necessitating a small configuration update.
Benchmarking reports relevant to the 9.0.0 release can be found in this post on Cardano Updates.
Known Issues
Cardano CLI
- In
cardano-cli-9.0.0.0, in the Conway era, thetransaction buildcommand automatically populates thecurrentTreasuryValueon every transaction. This should, however, happen only on Treasury donation transactions. This issue causes:- Transactions running Plutus V1, Plutus V2 and Simple scripts to fail at submission with
CurrentTreasuryFieldNotSupported. - Also, regular transactions created on one epoch and submitted on a different epoch fail with
ConwayTreasuryValueMismatch.
- Transactions running Plutus V1, Plutus V2 and Simple scripts to fail at submission with
⬆️ This is fixed on cardano-cli-9.0.0.1 Users are encouraged to use this latest version.
- In
cardano-cli-9.0.0.0, in the Conway era,transaction buildcommand may underestimate Plutus script execution units. This causes script execution to fail withoverspent budget. Usetransaction build-rawinstead.
No Conway Genesis File
Note that node 9.0.0 is supplied without a valid Conway-era Genesis file, which will be needed to cross the Chang hard fork. This will be supplied at a later date, necessitating a small configuration update.
