High level summary​

  • Work is ongoing on improving the Genesis tests. In particular, a centralized chain-sync-jumping model was developed to help troubleshoot test failures, which proved difficult to do using the decentralized model.
  • The Consensus team had its representative in the Node Diversity workshop. The report can be found in this link.
  • Collaborated with the Ouroboros Phalanx/Anti-Grinding Innovation Team, as an initial step in providing engineer input on the design.

High level summary​

  • Well-Typed has presented the penultimate milestone for the lsm-tree library. Table unions are now fully supported, tests include IO-error injection, and compatibility across Linux, Windows, and macOS has been demonstrated.
    • The next milestone will finalize the library's development, enabling its integration as a persistent backend for storing ledger state.
  • Several Consensus team members attended the Peras workshop. There is a brief presentation that can be accessed by following this link (password is GDdL*6M%). A design and implementation plan has been drafted. The next steps for Peras involve a decision by relevant stakeholders (Intersect Technical Steering Committee, involving SPOs and users) regarding the tradeoffs inherent to the protocol, such as additional operational costs, rewards and protocol parameterization regarding settlement times.
  • We held our technical working group meeting (recording), where we discussed:
    • The possibility of incorporating batch VRF support into ouroboros-consensus.
    • CDDL definition for Consensus: draft PR and next steps.
    • Should we support for NTC for older eras? (#1429).
  • Exposed a function that asks Consensus for the versions in which a particular query is supported, offloading this logic from cardano-api (#1437).
  • Exposed Byron cddls to be used from Consensus (#4965).
  • Added QueryStakePoolDefaultVote for 10.3 ([#1434](https://github.com/IntersectMBO/ouroboros-consensus/pull/1434 release consensus for node 10.3)).

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.
