Weekly Dev Update #91

THORChain Weekly Dev Update for Week 91, 30–06 May; Multichain Updates 0.49, 0.50, 0.51, Community Improvements, RUNEYield iOS Testflight app, RAISETHECAPS

Summary

Multichain — Continual Improvements

Three updates were pushed during the week to improve the stability of the network. Multichain is still stabilising, with another 1–2 weeks likely required to chase down edge cases. Once the network is stable, the contributors and community can go back to rolling out more chains and THORFi features.

Singlechain — Loss of sync

During the week SCCN suffered a loss of sync with Binance Chain, where more than 1/3rd of the nodes had an outage and the system could not come to consensus on some observed events. The team pushed back the churn to slow the process down, and rolled out an update that allowed nodes to manually make the missed observations. Most of the missed transactions were then observed, but unfortunately this caused some nodes to become corrupted, for an unknown reason. The easiest fix to this is for these nodes to leave the network. The team are still debugging this particular issue.

RAISETHECAPS

The caps were raised to 750k RUNE in order to increase load on the network. A lot of issues out of this event were subsequently fixed.
