• 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)

2024-01-10

• Today, we have worked on the following issues:

  • Activate babbage/conway eras on devnet #1425: the PR Activate babbage/conway eras in devnet #1427 has been updated and is ready to be reviewed. The new version of the devnet is now working with stake delegation, and it has a new hard fork option that defines the epoch at which the latest era is to be activated. 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

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
  • 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

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
