Cardano Node 8.10.0-pre

NOTE: THIS RELEASE IS ONLY RECOMMENDED FOR USE ON THE SANCHONET AND PUBLIC TEST ENVIRONMENTS (E.G. PREVIEW) AT THIS TIME. IT IS NOT RECOMMENDED FOR USE ON MAINNET.

This release contains the latest governance changes for SanchoNet. It has support for a new cost model for Plutus v3, plus new Plutus byte string primitives. The Constitution Committee quorum has been renamed to threshold in the CLI and a new economic parameter minFeeRefScriptCostPerByte has been added for reference scripts. This version of the node also adds support for reference scripts in the Conway era.

Changelogs

Node

Consensus

• Change the randomness stabilization window for Conway (and future eras) to 4k/f instead of 3k/f (one stability window) that was used for Babbage and TPraos-based eras. See erratum 17.3 in the Shelley ledger specs for context. Note that this is a backwards-incompatible change for all existing chains containing (at least one full epoch worth of) Conway blocks.
• Bugfix: DiskPolicyArgs were not being passed down to the ChainDB, resulting in default values for SnapshotInterval.
• Implement lightweight checkpointing #449. A validation to help nodes follow the historical chain. A new field topLevelConfigCheckpoints has been added to the TopLevelConfig record, with a new type CheckpointsMap.
• Compare TxIds based on the underlying hash so that they can now be seen as equal even if they are from different eras. This helps us with eg MsgHasTx from the LocalTxMonitor miniprotocol.

Ledger

• Retention of Anchor for proposal procedures in the ledger state for users to be able to query the node for those anchors

• The minimum fee calculation has been updated to take into consideration a new protocol parameter controlling the contribution of reference script sizes (minFeeRefScriptCostPerByte)

• Support for intra-era hardfork initiation and necessary updates to the SPO stake distribution calculation

• Fail translation when Conway features are present in transactions that use Plutus v1/v2

• Query-related changes:

Era-specific queries:

• Conway functionality supported only starting with Conway era
• Change committee query to return non-optional CommitteeMembersState
• Add optional Anchorto resigned status in CommitteeMembersState

Important bug fixes:

• Use the correct stake pool distribution for voting (instead of one that is an epoch too old)
• Fix DRep stake distribution to correctly add rewards to deleged stake
• JSON serialization of rational numbers in protocol parameters and governance procedures are encoded without loss of precision (BoundedRatio and Prices)
• JSON serialization fix for ConwayGovState

Network

Cardano-cli

• Add ref-script-size query command

• convert-cardano-address-key: support DRep and CC keys

• New required flag --reference-script-size for transaction calculate-min-fee

• Fix protocol params order for minFeeA and minFeeB

• Update CLI to use the term threshold instead of quorum for constitutional committee

• Add info about redeemers to the output of the transaction view command

• Add support for querying drep state and stake distribution by script hash

• transaction build{,-raw}: throw an error on identical action-ids in votes files

• Add --drep-script-hash parameter to conway governance drep retirement-certificate

• vote create: support DRep and CC script hash

• Add Plutus script hash support in update-committee, overnance committee create-cold-key-resignation-certificate and query committee-state commands.

• verification-key: support DRep keys as well as committee keys, extended or not

• Fix calculate-min-fee by switching to use Cardano.Api.evaluateTransactionFee
  instead of the deprecated Cardano.Api.estimateTransactionFee.
  This also deprecates the --mainnet, --testnet-magic, --tx-in-count,
  and --tx-out-count arguments to this command, which are no longer necessary.
  They can still be provided, but have no effect.

• Modified create-testnet-data option so that it registers DReps generated and delegates stake delegators to them. Also introduced transient drep delegation and refactored existing code so that more is reused.

• Extend committee create-hot-key-authorization-certificate to support scripts

• Modify query leadership: add --output-[json,text] flag to control format of the output. Previous behavior is preserved (write text to stdout, write JSON to file)

• create-testnet-data: fixes that the treasury could be unexpectedly negative

• create-testnet-data: fixes that the amount of delegated coins was incorrect

• Allow an output file to be specified for the various versions of query pool-state

• create-testnet-data: allow to specify relays for SPOs (like create-staked)

Cardano-api

• Add getReferenceInputsSizeForTxIds function.

• New Conway genesis parameter ucppMinFeeRefScriptCostPerByte needs to be set to the correct value after benchmarking.

• Add an extra parameter to evaluateTransactionFee, the reference script size, which the Ledger requires to estimate the minimum fee of a transaction.

• Replace unsafeMergeVotingProcedures by mergeVotingProcedures, that handles incompatible votes and return an error

• Undeprecate evaluateTransactionFee

• Re-implement evaluateTransactionFee using ledger's calcMinFeeTx
  The evaluateTransactionFee takes an additional utxo parameter and no longer takes byronwitcount.

• Add support for script-based CC members

Submit-api

NONE

Plutus

• New Plutus V3 primitives: byteStringToInteger and integerToByteString, enabled for Plutus V3 at Protocol Version 9.0.

Cardano Node 8.8.0-pre

NOTE: THIS RELEASE IS ONLY RECOMMENDED FOR USE ON THE SANCHONET AND PUBLIC TEST ENVIRONMENTS (E.G. PREVIEW) AT THIS TIME. IT IS NOT RECOMMENDED FOR USE ON MAINNET.

8.8.0-pre is a minor release of the Cardano node, with the main highlight being the ability to use Plutus V3 in Conway-era transactions. Plutus V3 brings several new capabilities such as a new Voting script purpose for writing voting scripts, access to governance actions in the ScriptContext, new cryptographic (BLS, Keccak256 and Blake2b-224) Plutus primitives, and more.

Changelogs

Node

• Mempool: add reason for transaction removal to TraceMempoolRemoveTxs.

Consensus

• Mempool: add reason for transaction removal to TraceMempoolRemoveTxs. This can be used in the node to enrich the trace output.

Ledger

• PlutusV3 support

• Support for governance policy script

• Remove the library cardano-ledger-pretty

• Ensure all sets are prefixed with tag 258 in CBOR serialization

• Added DRep injections into the ledger state, thus allowing more complex testing and
  benchmarking of Conway features

• Addition of new ledger events

• Increasing the limit for Url in Anchors to 128 bytes

• Provide accurate transaction fee estimation functionality for Haskell tools

• Important bug fixes:

  • missing "protocolVersion" field in JSON instance for Babbage and Conway protocol parameters
  • requiring witnesses for DRep registration
  • new committee governance action ratification was implemented incorrectly

  • failures during updates of Plutus CostModels were not retained
  • fixed the types for some protocol parameters in order to prevent values that are too large
  • serialization and CDDL fixes for transaction witnesses in the Conway Era

Network

  • Fixed Peer Sharing & light peer sharing bugs. Now peer sharing is more useful.
  • Balance peer sharing timeout to 5min for newly connected peers
  • Balance policyPeerShareRetryTime
• Experimental node-to-client version 16, which comes with a new version of local-state-query protocol.

Cardano-cli

• transaction build and transaction build-raw commands now parse optional Plutus script witnesses for votes and proposals
• Committee, DRep and DRep extended keys are able to sign transactions
• The "tx body intermediate format" is now fully deprecated
• create-testnet-data: better UX for supply arguments: have a flag for total supply and delegated supply is a fraction of that.
• add support for registration of script DReps;
• Add --drep-keys flag to create-testnet-data
• Make queries that optionally filter their result by DRep keys more explicit:
  • cardano-cli conway query drep-state
  • cardano-cli conway query drep-stake-distribution
• In transaction view and governance action view, replace:
  --output-format json by --output-json
--output-format yaml by --output-yaml
• governance vote view: use --output-format, like other commands, instead of --yaml
• create-testnet-data: rename --stake-delegators to --transient-stake-delegators
• Make query pool-state default to returning information on all pools
• stake-address registration-certificate: remove flag --key-reg-deposit-amt from all eras except conway
• Remove the constitution-hash option from the non-conway versions of query

Cardano-api

• Committee, DRep and DRep extended keys are able to sign transactions
• Fix bech32 prefixes for committee keys and key hashes
• Replace PrevGovActionId with GovPurposeId
• Implement TxProposalProcedures and TxVotingProcedures which enables Plutus script witnessing of proposals and votes.
• Remove support for intermediate tx body format.
• Add return value to `checkLedgerStateCondition
• Implement checkLedgerStateConditions. This new function gives direct access to the NewEpochState which contains the ledger state. It also requires an EpochNo upon which it will terminate if the supplied condition is not met.
• Restore the inclusion of datum hashes in Alonzo era tx bodies

Submit-api

NONE

Plutus

• Plutus V3 support (governance scripts; BLS, Keccak256 and Blake2b-224 cryptographic primitives)
• Improve the performance of eq, geq and leq operations on Value
• Implement common subexpression elimination for UPLC
• Add some helper functions for working with Plutus V3 ScriptContext

Note that there is no support in this release for bitwise primitives integerToByteString and byteStringToInteger in Plutus V3. These primitives will be enabled in the near future, and additional bitwise primitives are planned further ahead.

Cardano Node 8.7.2

Cardano Node 8.7.2 brings the CLI refactoring from sanchonet to mainnet to allow teams ample time to update their components in preparation for 9.0. It also has improvements to the P2P networking layer. The high-level changelog updates below are significant changes since 8.1.2 mainnet release and only focus on the node running in the babbage era.

Benchmarking reports relevant to the 8.7.2 release can be found in this post on Cardano Updates.

The Conway genesis filé needs updated to latest sanchonet version. Check the linked configuration files below.

Breaking changes:

• cardano-cli has dropped some byron era commands (see detailed changelogs for details)
• While we don't anticipate any breaking changes and our regression test suites have passed, beware that major refactoring has happened on cardano-cli since 8.1.2.
• libblst is a required dependency now in preparation for next hard fork

Known Issues

• list of 8.7.2 issues
• list of cardano-cli issues

Changelogs

Node

NONE

Consensus

• Changing the selection now traces the entire SelectView (including the tiebreaker VRF)

Ledger

NONE

Network

• Introduces light peer sharing: incoming duplex connections become known to
  the outbound governor.
• Fixed issues with random peer selection for sharing.
• Addressed asynchronous demotion issues, preventing peers from remaining
  indefinitely in certain states (the bug).
• Fixed a bug where peers marked with DoNotAdvertisePeer were being shared.
• Clarified distinction between pools of peers for sharing and requesting.
• Updated types for PeerSharing, including removal of PeerSharingPrivate
  for symmetric handshakes, improving compatibility and fixing specific
  issues.
• Changed encoding for IPv6 addresses in the PeerSharing protocol.
• Introduced NodeToNodeVersion_13 - this version fixes the negotiated value
  of PeerSharing and deprecates PeerSharingPrivate. Older versions would
  wrongly echo the proposer's PeerSharing value so version 13 disables peer
  sharing with older versions to not lead into unwanted disconnections.
• Made ChainSync idle timeout configurable.
• Updated KeepAlive client for better round-trip time sampling.
• Introduced less aggressive churn for established and known peers.
• Added new PeerStatus PeerCooling to manage asynchronous demotions more accurately.
• Introduced big ledger peers to the outbound governor.
• Fixed a small memory leak in PeerMetrics.
• Made DNS resolution for peers more efficient and limited concurrency for
  faster and more stable connections.
• Improved memory footprint for peer metrics.

Cardano-cli

Introduction of Top-Level Command:

• cardano-cli 8.17.0.0 now features as a top-level command, exemplified by commands like cardano-cli conway, cardano-cli babbage, and cardano-cli alonzo.

This refactoring is crucial for the seamless integration of the Conway era, which introduces significant changes compared to Babbage and previous eras. This enhancement aims to improve user experience by tailoring the CLI to display only the commands and flags relevant to the current era. For example, Conway-specific commands are not displayed in Babbage, and Babbage options that would be nonsensical in Conway are appropriately excluded (i.e MIR certificates and update proposals by genesis keys)

Please be aware that commands are actively under development, and changes or refinements may still occur in upcoming releases.

Preservation of Legacy Commands:

• cardano-cli 8.17.0.0 retains all commands from cardano-cli 8.1.2 (the previous release suitable for mainnet). These commands are designated as "legacy commands," ensuring users transitioning from cardano-cli 8.1.2 can seamlessly continue their operations without disruption while they smoothly transition into the new commands structure.

Known Issues:

There are a few minor bugs related to Conway era integration where Conway subcommands are spilling over to previous eras and the legacy commands. For updates on these issues, please refer to cardano-cli repository.

• The legacy command "cardano-cli transaction build" currently displays options --vote-file and --proposal-file.
• The legacy command cardano-cli query presents the subcommand constitution-hash which is irrelevant for babbage era
• cardano-cli babbage stake-address registration-certificate and cardano-cli stake-address registration-certificate show the flag --key-reg-deposit-amt but it is really not needed on Babbage. This will be removed, however the its presence and the removal is purely cosmetic since the resulting certificate does conform to the Babbage cddl. In other words, using this flag does not have any impact. The deposit in Babbage era should be supplied on the current fashion: when balancing the transaction.
• The output of cardano-cli babbage query stake-address-info shows the voteDelegation field which does not have any meaning in Babbage and is Conway specific to display the DRep that we are delegating to.

Cardano-api

• Major refactoring of API (see detailed changelogs for API below)
• Fix the inclusion of datum hashes in Alonzo era tx bodies
• New ToJSON instance for TxValidationErrorInCardanoMode
• Remove ByronTx data constructor from data Tx era
• Delete Cardano.Api.Eon.ByronEraOnly module
• Remove TxFeeImplicit and TxValidityNoUpperBound

Submit-api

• Remove support for Byron transactions
• Update cardano-cli-8.17.0.0 and cardano-api-8.36.1.1
