Summary
TLDR: DYdX Chain, the blockchain for dYdX perpetual futures exchange, experienced a 9-hour outage due to a software bug during a scheduled upgrade. The fix was released, and block production resumed. The chain halt caused a price increase in DYDX token. The upgrade introduced new features and the chain supports liquid staking.
Key Points
1. dYdX Chain experienced a major outage due to a scheduled v4 upgrade, lasting nearly nine hours before a fix was implemented.
2. The chain halt was caused by including the wrong version of a bug fix in Cosmos’ IAVL library, leading to corruption in the network’s state during the upgrade.
3. Despite the outage, dYdX’s native token (DYDX) saw a 4% price increase during the chain halt.
