High level overview​

This week, the Mithril team continued working on completing the adaptation of the Mithril client as a library. They progressed in decentralizing the Mithril networks with the peer-to-peer (P2P) networking proof of concept, achieving the implementation of a very basic working demo with a peer-to-peer publish-subscribe (pub-sub) mechanism. Additionally, the team continued working on the deterministic computation of the UTXO/transactions set from the immutable files.

Finally, they resolved the naming issue of the Docker package responsible for storing images of the new Mithril client CLI, and continued addressing a performance issue associated with the 'release-mainnet' aggregator.

Low level overview​

• Worked on the issue Prototype a P2P relay with libp2p #1300
• Worked on the issue Light Wallet: Release mithril-client library #1311
• Worked on the issue Light Wallet: Compute deterministic Cardano UTxO/transactions set PoC #1283
• Worked on the issue release-mainnet aggregator is unreachable #1310
• Completed the issue Client Docker package is incorrect #1322

High level summary​

This week the Consensus team made progress on two fronts: the question of survivable eclipse duration, which is part of our work supporting Genesis delivery, and how to improve the handling of blocks from the future. Regarding the UTxO-HD branch, we managed to run a node with legacy blocks, which is syncing with mainnet, up to including Alonzo. We also investigated a regression in mempool snapshotting, which was ultimately solved by a Ledger update, and will be fixed in the upcoming Node 8.6 release.

High level overview​

This week, the Mithril team kept working on decentralizing the Mithril networks with the peer-to-peer (P2P) networking proof of concept. They progressed with the adaptation of the Mithril client as a library, and worked on its full WASM compatibility in a proof of concept. The team kept working on the deterministic computation of the transactions from the immutable files, and fixed some unreachability issue on the release-mainnet aggregator.

Finally, they implemented new Docker images that build the Mithril nodes on the 'devnet' faster and fixed some regressions in the Mithril client CLI.

The team works on applied research and consulting in formal methods that is directly applicable to evidence based engineering in Core Tech and beyond.

High level summary​

The team is currently formalising mini protocols and writing a paper on performance modelling

Details​

• completing work on chain sync mini-protocol

• analysing timeouts

High-level summary​

This week, the Hydra team fixed the gen-hydra-keys command to avoid overwriting existing keys, and resolved issues related to the rewritten hydra-tui. They also worked on a "dirt road" implementation for the "Ignored init tx" notification, improving the robustness of the system.

The team finalized preparations for the Cardano Summit presentation, including implementation of the hydra-poll example DApp.

If you happen to read this and attend the Summit in Dubai, make sure to check out our Masterclass about "Developing Hydra + Mithril for Scaling Cardano" on Friday, November 3 at 14:00-15:30 local time in the "Al Dar" room!

What did the team achieve this week​

• Fix gen-hydra-keys command to not overwrite existing keys #1136
• Fixed the rewritten hydra-tui #1113 #1137
• Finalized cardano summit preparation #1109
• Implemented the hydra-poll example DApp link to repository
• Dirt road implementation for "Ignored init tx" notification #529

What are the goals of next week​
