High level summary​

• Merged the Genesis Documentation (#1174). Its rendered version can be found here.
• Fixed a chain sync jumping test failure, and introduce some minor improvements (#1417).
• Merged the first draft describing Era Transition Governance (#1408).
• Added a block diagram of a full block.

High level summary​

• Added a significant amount of content to the Consensus blueprint documentation. There are new sections that describe different aspects of the Consensus layer (such as chain selection or ledger queries), Storage layer, and Mempool.
• Javier and Nick, two of the Consensus team members participated in the Cardano Dev Pulse Podcast where they discussed UTXO-HD and Genesis.

High level summary​

• Added a document that discuses ticking and how its used within the Consensus layer (#1385). The rendered version of this document can be accessed in our documentation page.
• The benchmarks for the UTXO-HD version of Node with the in-memory backend confirmed that its resource usage is on par-with the baseline version of the Node. There is a slight decrease in CPU usage (-9%), and a slight increase in memory consumption (+3%).
• Fixed the mempool snapshotting regression in the UTXO-HD branch (from +185% to -21%) (#1382).
• Added a Consensus section to the Cardano Blueprints (#7).
• Held the technical-working group meeting. The recording can be accessed using this link. In particular, the importance of the KES agent and its roadmap were discussed during this meeting.

High level summary​

• Opened a Draft PR for a CIP to remove EBBs from the historical chain.
• Opened a Draft PR for a CPS regarding low participation scenarios.
• Identified the threads in Cardano node which were unlabeled (#6086). We're working to add the missing labels, which will help with debugging and error tracing efforts.
• Got the results for the UTxO-HD V2 InMemory cluster run, which show that there is a regression in mempool snapshotting. Investigation is ongoing.
• Fixed the block replay tracer in the new tracing system (#6091).
• Adapted UTXO-HD to take advantage of the fact that TxOuts are forward deserializable (#1360).
• Merge PRs upstream to enable the new QueryStakePoolDefaultVote (#5055, #4860, and #1373).
• Merged LocalTxMonitor changes into network-protocols, which constitutes a first step towards enabling the LocalTxMonitor to report other dimensions of the transaction size.
• Completed first pass at a script cataloguing all of the consensus symbols used in downstream packages, as part of our contributions to the Cardano Blueprint efforts.

High level summary​

Our quarterly objectives are now drafted and can be accessed here.

The team continued working on documentation improvements, enhancing the security of the Consensus layer, and being involved in the early stages of the Peras workstream.

We are updating the UTXO-HD branch to make use of the forward-deserializability of transaction outputs (TxOuts) (see #1360, #1361, and #1362). We performed a local chain sync with a the latest version of an UTXO-HD enabled node, using the in-memory backend.
