Logbook

This page records a log of the team’s work, thinking, discussions, pains, joys, events, and experiences that happen on a daily basis. It’s supposed to be a kind of Stream of consciousness that can later be searched, analyzed, reviewed in more formal retrospectives.

Rules:

• Log days in reverse chronological order, recent first

• When the stream is getting too big, such that github refuses to render do the following:

  • extract biggest logical section (half-year or quarter) out of this into a correspondingly named Logbook-Year-Hn.md or Logbook-Year-Qn.md page
  • update links on top of this page to make it easier to navigate try to fix all links in the wiki at least
  • notify the team

• Move (and link) recurring sections to relevant dedicated pages.

• Today, we have worked on the following topics:

  • Some end to end tests are flaky in the CI #1147: we are still investigating flakiness that seems to originate form the Cardano devnet
  • Implement transactions verification in client library #1468: the PR Add Cardano transactions proofs support to mithril-client #1489 been reviewed and merged. This closes the issue
  • Create a test network on SanchoNet #1173: the PR Support Sanchonet Cardano network #1384 has been reviewed and merged, and the genesis certificate of the network has been bootstrapped. The network should start producing certificates tomorrow. The PR Add dev blog post announcing testing-sanchonet network #1491 has been created and will be merged early next week to announce the availability of the network
  • Enhance Mithril/Cardano node communication #1315: the PR get datums using pallas observer #1403 will be merged when the new crate version of pallas is released
  • Handle cancellation of certificate verification in WASM client #1480: We have paired on this issue and it seems that we can probably delegate the full responsibility of cancellation to the browser itself with the use of an AbortController. We will attempt to do this implementation shortly
  • Upgrade http dependency #1474: the PR Remove http from dependencies #1490 has been created, reviewed and merged, which closed the issue
  • Generate automatic documentation for CLIs #1471: the PR Generate documentation on module command lines #1424 is being updated to add examples in generated descriptions
  • Improve signed entity test #1460: the PR is validated and will be merged shortly

• We have also worked on the sprint planning for the next iteration

2024-02-07

• Today, we have been working on the following issues and PRs:
  • Some end to end tests are flaky in the CI #1147: We have kept investigating the cause of the flakiness observed with the end to end test Cardano network. We have reproduced the same flakiness on an ephemeral self hosted GitHub Actions runner. We have also detected that there was probably an error when generating the topology files for the Cardano full nodes. We are working on a fix to verify if this is the root cause of the flakiness
  • Implement transactions verification in client library #1468: the PR Add Cardano transactions proofs support to mithril-client #1489 has been created and is pending review. It will be merged shortly
  • Create a test network on SanchoNet #1173: the PR Support Sanchonet Cardano network #1384 has been updated and is pending review. It will be merged shortly. The new testing-sanchonet has been fully configured to handle on chain era markers. We should be able to genesis the certificate chain tomorrow and see the first certificate produced the day after tomorrow.
  • Enhance Mithril/Cardano node communication #1315: the PR get datums using pallas observer #1403 will be merged when the new crate version of pallas is released

2024-02-05

• Today, we have worked on the following issues:
  • Some end to end tests are flaky in the CI #1147: we have kept investigating the flakiness of the CI. It appears that since the new version of the devnet has been released, most of the flakiness occurs on the Cardano network which gets stuck after few epochs in flaky way. We have implemented some CPU throttling on the end to end test and we have been able to reproduce the error messages which occur most of the time. We are trying to understand if the source of flakiness could be attributed to the underlying GitHub Actions runners

• During our team session, we have discussed about the following topics:

  • Decentralized key registration:
    • We will soon work on a 'naive' decentralization through the P2P network layer that we have implemented. In that case, we acknowledge that there is absolutely no guarantee that this will be stable enough to go to production as is
    • We could possibly make all the signer node aggregate signatures (but not handle the heavy duty task on creating/hosting the artifacts) which could mitigate the adversaries behaviors in P2P signer registration
    • This will give us knowledge and feedback that we will use to hopefully find solutions to this problem
    • Also it is a door opener for working on a fully decentralized Mithril network
    • We have also imagined an on chain signer registration that would be automated provided some script send few ADAs at regular intervals to an address whose private key is on the signer node (avoiding the burden of manual transactions done every epoch, but there is still an associated cost)
  • We talked about the new version of the Mithril client available in the browser and that will soon provide transaction verification capability
  • We have also talked about the new version of the devnet and of the end to end test that allows us to thoroughly test the new Pallas chain observer (UTxO retrieval and hard forks compatibility)

The execution time has also been significantly reduced (<1min, -50% drop). Finally, we will implement the transition to the Cardano chain observer for the eras reader which will give us more control for testing the Pallas chain observer
  • Implement a fake standalone aggregator #1397: we have kept working on the implementation of tests for the Open API specifications conformity. The PR will be updated shortly
  • Implement the mithril client WASM package in the explorer #1409: the PR Implement mithril client wasm in explorer #1426 has been created and is pending review. We still need to fix the explorer build in the documentation workflow as it needs to use the WASM package that is produced in the CI
  • Enhance Mithril/Cardano node communication #1315: we have kept reviewing the PR get datums using pallas observer #1403 which is almost ready to be merged
  • Generate documentation on module command lines #1424: the PR is pending review

• Following the epoch gap, the testing-preview network has been re-genesis and it should resume producing certificates tomorrow

• Today, we have worked on the following issues:

  • Implement ChainObserver adapter configuration in aggregator #1396: the PR has been merged. This closes the issue
  • Activate babbage/conway eras on devnet #1425: the draft PR Activate babbage/conway eras in devnet #1427 has been created. We have migrated the legacy devnet to the new development and made the end to end test successful (except for the stake delegation part) which is more complicated. We have also prepared a mechanism for switching to the latest hard fork at a specified epoch number. We will keep working on it tomorrow

• We have noticed that the testing-preview network was not producing certificates any more for a few days. It happened that there was a communication problem between the signers and the aggregator on the VM (which was fixed by restarting the aggregator container). This implies a re-genesis of the chain which will take place tomorrow and the network should resume signing the day after
