THORChain Weekly Dev Update for Week 92, 07–14 May; Multichain Updates 0.51, SCCN Update 0.19.3, 0.19.4, THORWallet, THORName.com, THORChain.tools, updates to explorers and more

Summary

Multichain — Continual Improvements

MCCN has been quite stable, only a single update during the week with non-critical improvements.

Singlechain — Loss of sync

Singlechain suffered a loss of sync and some nodes became corrupted. The solution was to wait until Churn then manually return YGG funds. The network stability issues around Singlechain are still on-going. Once stability is achieved a post-mortem will be released. It turns out a lot of the fixes have already been applied to MCCN, so it has been a matter of back-porting to SCCN. As of yet, no SCCN issues are applicable to MCCN.

RAISETHECAPS

The caps were raised to 1.5m RUNE in order to increase load on the network. A lot of issues out of this event were subsequently fixed.

Updates

THORNODE MCCN UPDATE 0.51.0

This release contains the following fixes
1. [BUG] Make sure churn out node get their bond reward PR: https://gitlab.com/thorchain/thornode/-/merge_requests/1683
2. [BUG] Allow yggdrasil to spend UTXO that is less than 10k sats. PR: https://gitlab.com/thorchain/thornode/-/merge_requests/1684
3. [BUG] When choosing yggdrasil vault to send out outbound tx ,deduct MaxGas fee from yggdrasil vault when there are outstanding outbound PR: https://gitlab.com/thorchain/thornode/-/merge_requests/1689

THORNODE SCCN UPDATE 0.19.3

There are two changes in this release:
1. Add “observed-tx” command to thorcli , thus node operator can submit a manual observation. PR: https://gitlab.com/thorchain/thornode/-/merge_requests/1685
2. Extend the TSS Keysign hard timeout limit from 5minutes to 10 minutes, allow TSS keysign to retry 3 times. PR: https://gitlab.com/thorchain/thornode/-/merge_requests/1686

THORNODE SCCN UPDATE 0.19.4

Fix1: It has been discovered that the tx hash id in MsgTssKeysignFailure is faulty , the code didn’t generate tx id appropriately, the issue had been fixed in multichain a while ago , this is back port it to single chain chaosnet , the team believe this cause the block size to be big , and cause sync issues with thor-daemon

PR: https://gitlab.com/thorchain/thornode/-/merge_requests/1696

Once all nodes apply this change , the MsgTssKeysignFailure will become small

Fix2: With the help from a node operator , the team found out that for some reason the tx send to thorchain sometimes is unsuccessful , which bifrost keep retrying , it only recovers after restart, unfortunately bifrost didn’t log the error message about what cause it to fail , this PR will log the error message , and then panic after 5 retries , thus bifrost pod can restart
