Weekly Dev Update #48

Summary

Internal Audit

The team spent the week going over every line of code in the main THORNode repo as they move towards a Gold Master release for Chaosnet. There is not anticipated to be any final business logic feature changes to THORChain as they move to stabilise the code base.

Testnet 3.5

The team re-deployed a new testnet during the week which fixed some issues found in the previous week. A new testnet involves a new THORNode binary, updated Midgard and a refreshed frontend client. Users will notice subtle changes to make the client stable.

Unbond Memo

New logic has been added to allow a node operator in the pending queue to leave the system, or reduce the amount of bond they have. This will facilitate a Node Operator to take profits from their rewards whilst they are in standby, or take some of their bond and stake it to pursue better yield.

Bundled Witness Transactions

Logic has been added for the Bifrost to bundle multiple witness transactions together, reducing the amount of bandwidth on the system.

THORNode

Bugfixes from testnets, as well as some quality and feature inclusions from testing.

Community Work

The community are building out:

• THORNode telegram bot: https://github.com/block42-blockchain-company/thornode-telegram-bot

• THORChain community explorer: thorchain.community
• THORChain arbitrage bots: https://gitlab.com/thorchain/trade-bots

In addition, the team are also talking with a mobile wallet provider and hace commissioned a team to build a blockchain explorer.

• 1 observation related to general code safety [NOTED]

Gauntlet are preparing their final THORChain report.

Next Milestones
