Weekly Dev Update #66

THORChain Weekly Dev Update for Week 66, 21–26 Oct; Removal of 24hr liquidity limit, LastObserved for each Node, Auto-restart for Binance and more.

Summary

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

Removal of 24hr TimeLimit on Liquidity

With “confirmation counting” now implemented for PoW chains, the timelimit for adding liquidity can be removed. It was only added as a blanket solution to allow liquidity providers of any chain to deposit assets into pools, and be credited their liquidity immediately.

Instead, the team (to reduce complexity) pushed logic for conf-counting back to the Bifrost level, so it will count confirmations prior to telling THORChain about a new event. This means when users add liquidity in large amounts they will be delayed if they exceed the block rewards for that block.

For instantly final chains conf-counting is not necessary.

LastObserved

When a node makes a witness transaction they will now include the blockheight of the event. This will update a new parameter on each node “last observed” on a per-chain basis. This will allow dashboards to be built that can easily show the sync status of all nodes at any time — if they are up to date then they will show the same last observed for each chain. If they are offline (or just have a single chain client crashed) then bots and alert services can easily compare and notify.
