High level summary​

• We continue to remove irrelevant eras from cardano-cli with an aim to simplify the Haskell code and the interface exposed to the user.
• During a working group meeting a user pointed out the possibility to specify an incorrect anchor data hash. This has been largely rectified in cardano-cli but there is some more work to be done particularly in the transaction build command.
• We added the possibility to specify supplemental datums and other minor improvements in this sprint.

cardano-cli​

• Add a test of create-cardano
• Add anchor data hash checks to remaining governance action commands
• Add hash validation and support for HTTP(S) and IPFS to command hash anchor-data
• Add proposal hash check when creating info governance action
• create-testnet-data: take optional node configuration file as input and check/add genesis hashes and paths
• Remove era|legacy transaction view
• Remove eras older than Babbage support in transaction build and transaction build-estimate
• Remove legacy commands
• Update create-treasury-withdrawal

cardano-api​

• 638-Allow next leadership-schedule at 4k/f
• Add new field 'inlineDatumRaw' to TxOut ToJSON instance
• Introduce supplementary datums
• Make IsXXXBasedEra a class hierarchy

cardano-node​

• cardano-node 9.2.0 release
• cardano-tracer: Allow switching EKG service between different nodes.
• cardano-tracer: OpenMetrics compliance for Prometheus; fix forHuman output in journald

cardano-testnet​

• cardano-testnet: Code sharing in Defaults.hs
• cardano-testnet: rename ShelleyTestnetOptions into GenesisOptions

High-level overview of sprint 70​

Cardano CLI​

cardano-cli ping command cannot send pings over unix sockets using node-to-client mini-protocol (since it doesn't support it). In that case, the command will now show a user-friendly error message. See cardano-cli#49.

Mithril​

We held a session with the mithril team to discuss design & implementation of Mithril using ouroboros-network.

Ouroboros-Network​

TxSubmission Logic​

We continued working on tx-submission logic. We developed new tests that run several simulated outbound peers offering transactions and a single inbound peer governed by the new tx-submission logic. Ref ouroboros-network#3311.

The next step is to clean the branch and integrate it with ouroboros-consensensus & cardano-node for early e2e tests.

Bulk-Sync for Genesis​

We reviewed the new bulk-sync application for Genesis mode, see ouroboros-network#4919.

Typed-Protocols​

We reviewed the new typed-protocols API PR. It was recently merged & published to CHaP. Once Haskell.Nix has better support for public sub-libraries, we will package all the libraries in one package and publish it on Hackage. Ref: typed-protocols#52.

The next step is to update, review the integration PR in ouroboros-network, see ouroboros-network#4935.

Nightly Tests​

We fixed a long-due failure on a nightly test. The failure was due to IOSimPOR ability to reorder simulated IO actions, resulting in a wrong order of events. So, it's not a bug in the production code but in the test itself. See ouroboros-network#4948.

Updated readme file​

We updated the dependency graph in our README.md file.

Next Sprint​
