High level summary​

During the Past two weeks we drafted an implementation path for concluding that a node is caught up, which will also be used to back Network's ledger-peer selection (see this issue). We also carried a thorough investigation into the exact feasibility of applying the Genesis rule to certain historical parts of the chain.

On the UTxO-HD front, we are working on improving the ledger tables design and wrapping up the improved DB locking mechanism. We also released packages that are required not only by UTxO-HD but are already used in cardano.

UTxO-HD​

  • We have a plan for making the ledger tables in UTxO-HD more ergonomic by mimicking SOP classes like HPure and HAp . In short, we implement generalised versions of important classes like Applicative and Traversable.

Support​

  • fs-sim-0.1.0.2 and fs-api-0.1.0.2 were released, which makes them now compatible with GHC up to 9.6.
  • ouroboros-consensus-0.7.0.0 was released for cardano-node 8.1, including query serialization fixes for backwards compatibility.
