Blockchain Updates:

Chain stuck issue

Last week, the blockchain team continued investigating the testnet chainstuck issue. They discovered that the issue was caused by the MPT, which had not caused any problems for almost a year, however, during chaos and load testing the issue emerged. While the key code that caused the issue has not been located, it is likely that the MPT was corrupted during the syncAndRetry process. To address this, the team added more detailed logs in the MPT for deleting nodes and added state nodes validation after syncing the missing nodes from remote. Previously, the retrieved nodes with the new calculated keys were simply put into stateDB without any validation, which could have caused the MPT issue. The team is currently exploring if these issues are related.

Other issues:

Additionally, the team worked on load testing, which was broken after a few recent changes. There were also remaining issues after enabling txn fee, and the team identified errors in sending and verifying transactions code that returned errors before completing the transaction sending process due to early context cancel calling. The team is planning to send txn confirmation requests to more nodes so that when chaos tests bring down sharders, there is at least one request that reaches the live node.

In addition to the above work, the team also reviewed the view change code for the manual view change. However, this feature requires all miners to be involved in creating a new magic block with new DKG, which is not a trivial task. Therefore, the team has decided to pause this feature and focus on closing the existing issues.

Also, the team also investigated a sharder crashing issue on staging, which was introduced after enabling the empty read pool. The empty read pool did not cause an immediate panic when it was created, but it caused a panic later when saving txns to cassandra. The team is still working on this issue and expects to fix it in the coming days.

Furthermore, during the week, the team merged 12 PRs in 0chain, 11 PRs in gosdk and 9 PRs in blobber repos:
