Summary

The team worked on Chaosnet stability, testnet fixes, and multi-chain tweaks. Midgard was also updated

Releases

A point release was made for Chaosnet to fix an issue where KVStore information was being returned for a blockheight that was not the latest (default, expected). This was causing arb bots and other infra that was querying the state machine to receive incorrect information. The release was made since it was affecting bots in production.

Midgard V0.5.0 and V0.5.1 was released with some improvements and updates. Details below.

THORNode

The team deployed fixes for V0.16.1, as well as multi-chain bug fixes found on testnet. In addition some small changes to THORNode events to allow the new Midgard V2 to more efficiently index events.

Midgard

Fixes and tweaks for stability, as well as releasing V0.5.0 and V0.5.1. In addition the queue was proxied to allow services to query for outbound queue length, which is somewhat of a measure of the load on the system. If the queue is ever found to be growing steadily with now reductions, then it points to a backlog and an issue with outbound processing. During one TSS-related bug, the queue reached over 300 transactions.

Devops

New versions were shipped, as well as a simple fix to the Binance Chain node running out of resources and crashing (being the open file limit). This should make it more stable. In addition, two points from an upcoming infra audit were addressed, which were to remove external dependencies (since they are attack vectors).
