- dYdX Chain halted for 9.5 hours due to a scheduled v4 upgrade and resumed operations later.
- An incorrect bug fix from Cosmos’ IAVL library caused network state corruption during the upgrade.
- DYDX token price increased by 4% during the outage, showcasing investor confidence in the platform.
dYdX Chain, the foundation for the perpetual futures exchange dYdX, encountered a long 9+ hour halt early Monday morning. This interruption, deemed a “major outage,” was a consequence of a scheduled v4 upgrade to the chain.
Following approximately nine and a half hours of downtime, dYdX implemented a fix for the software bug, allowing enough validators to engage, consequently enabling dYdX to recommence block production midway through Monday.
The outage lasted for nine hours and thirty-two minutes, according to dYdX’s status page, however, the network showed resilience in promptly addressing and rectifying the issue.
The implemented fix by dYdX does not constitute a state-breaking change, ensuring compatibility with prior versions of the blockchain. Throughout the chain halt, dYdX’s perpetual futures DEX remained fully operational once again, showing the platform’s commitment to maintaining continuity in service provision despite technical challenges.
The root cause of the chain halt was said to be the incorporation of an incorrect version of a bug fix from Cosmos’ IAVL library into the dYdX software release. This resulted in corruption within the network’s state during the upgrade process.
Curiously, the price of dYdX’s native token (DYDX) experienced a 4% increase after the onset of the chain halt at approximately 3:00 am ET on Monday, reflecting investor confidence in the platform’s resilience and long-term prospects.
The v4 upgrade of the dYdX Chain introduced minor improvements to the trading platform and established mechanisms for mitigating malicious behavior among validators through governance votes. The upgrade passed through a nearly unanimous community vote of the dYdX ecosystem in driving continuous improvement and innovation.
