DYdX Chain Block Production Now Resuming After Over 9 Hours of Downtime

Key Points:

• DYdX Chain, supporting the dYdX perpetual futures exchange, faced a significant nine-hour outage due to a scheduled v4 upgrade.
• The dYdX Chain block production halt is the first major one since the launch of dYdX version 4 on its standalone Cosmos blockchain.
• Despite the outage, dYdX’s decentralized exchange remained operational as blockchain networks continued to grapple with maintaining stability.

DYdX Chain, the backbone of the perpetual futures exchange dYdX, faced a significant outage early Monday morning due to a scheduled v4 upgrade.

DYdX Chain Block Production Halts: Critical Bug Disrupts Perpetual Futures Exchange

Lasting for nine hours and 32 minutes, the disruption was resolved after dYdX released a software fix for a critical bug. Despite the halt off dYdX Chain block production, the perpetual futures decentralized exchange (DEX) remained functional throughout the ordeal.

This outage marks the first major disruption since the launch of dYdX version 4 and its standalone Cosmos blockchain in October. The incident, triggered by a glitch in the IAVL library of Cosmos, caused state corruption during the upgrade process, as reported by Blockworks. Scheduled maintenance for the dYdX Chain was completed at 6:30 a.m. UTC, but issues arose just 20 minutes later.

dYdX Team Swiftly Resolves Critical Bug

The dYdX team swiftly addressed the issue, emphasizing that the fix would not compromise compatibility with earlier versions of the blockchain. Engineers immediately began debugging, ultimately implementing a fix by 4:23 p.m. UTC. By midday Monday, with enough validators on board, dYdX Chain block production resumed.

The disruption underscores the challenges inherent in maintaining blockchain networks, with dYdX joining recent examples like Solana and Polygon zkEVM in experiencing significant interruptions.
