High level summary​

• The scope for the first Consensus Leios demo has been defined and can be accessed via this link. The team has started prototyping the mini-protocols, new components and demo infrastructure, using the actual node as the base for the prototype.
• The ThreadNet tests have been updated in preparation for upcoming work on Peras tests, as well as testing that the node can fork into the next Dijkstra era (#1689).
• Most of the work integrating LSM trees into consensus has been merged into our repository (#1700, #1653, #1652, #1603, #1572). The integration of LSM trees into the node will require only minor consensus modifications, such as exposing new symbols.
• The second Peras PR has been merged (#1674). A new one is now ready for review by the Consensus team (#1678).

High level summary​

• Added a Linear Leios draft impact analysis for Consensus.
• Tweag showcased the first Peras milestone. The demo is accessible through this link. The first Peras PR, which introduced the basic types to support Peras, was merged into main. The second Peras PR is currently under review.
• KES agent code changes have been integrated as part of version 10.6. The KES agent is not active yet; release is pending audit and integration testing on our end.

High level summary​

The Consensus team is drafting an architectural design based on Leios CIP-0164 (draft). The design document is currently in draft form and can be found at this link.

The team has also completed augmenting the hardfork combinator to be Peras-aware (#1681).

High-level summary​

Over the last two weeks, the team has been working on the first public draft of the Leios CIP, LSM-tree support, and the KES agent integration and audit.

• Contributed text and review to the first public draft of the Leios CIP: https://github.com/cardano-scaling/CIPs/pull/11
• Released cardano-lmdb-simple 0.8.1.0 with features to support range reading keys from LMDB in which the Haskell order does not match the Serialized order: https://chap.intersectmbo.org/package/cardano-lmdb-simple-0.8.1.0/
• Fixed leaking handles in uncommitted forkers. This should in particular help with queries, which were presumably leaving behind open handles: https://github.com/IntersectMBO/ouroboros-consensus/pull/ 1640
• Refactored consensus-internal code to group snapshot-related functions into a SnapshotManager in preparation for LSM-trees: https://github.com/IntersectMBO/ouroboros-consensus/pull/1643

High level summary​

Over the past couple of weeks, the team continued working on LSM and KES agent integration, as well as Peras implementation. On the Leios prototyping front, the team is currently drafting a section in the Leios CIP focused on the new mini-protocols.

Two small improvements to Genesis tracing and metrics were also introduced: #6306 and #1628.
