Starknet Suffers Second Major Downtime in Two Months

Starknet, Ethereum’s seventh-largest Layer-2 network, faced a downtime for nearly three hours on Tuesday, marking its second major outage in under two months. The disruption follows the deployment of the Grinta upgrade (v0.14.0), a major milestone aimed at decentralizing the protocol.

Sequencer Fails After Network Upgrade

The outage lasted 2 hours and 44 minutes, beginning around 2:23 AM UTC. Starknet’s sequencer, responsible for ordering and processing transactions – failed to function, halting block production entirely.

All transactions between block 1,960,612 and 4:36 AM UTC were lost and must be resubmitted, following a full chain reorganization. This rollback effectively erased an hour’s worth of blockchain activity.

Grinta had introduced core architectural changes, including a revamped sequencer, mempool logic, and a redesigned fee structure, all aimed at improving decentralization.

Reliability Concerns Mount After Starknet Downtime

The incident follows a 13-minute stall in July, which was previously the network’s most significant disruption. Two back-to-back outages have intensified scrutiny over whether high-performance Ethereum scaling solutions can maintain both speed and operational resilience.

Starknet currently holds over $548 million in total value locked, according to L2Beat data. Its growing ecosystem and rising ambitions make operational stability critical to long-term adoption.

Team Says Network Is Fully Restored

By early Tuesday morning, the Starknet team confirmed that the network had returned to full functionality.

“Block production is back to normal. Most RPC providers are up-and-running,” the team stated on X. “Transactions submitted during the outage were not processed and must be resubmitted.”

The team pledged to publish a detailed post-mortem in the coming days, covering the timeline, technical root cause, and prevention measures.

Upgrades Bring Progress and Risk

The outage comes shortly after Starknet’s governance community approved SNIP-31, a proposal to integrate Bitcoin staking. The network is positioning itself as a future-proof L2 with multi-chain interoperability and modular architecture.

But the Grinta incident highlights a broader risk: complex upgrades, even those aimed at decentralization can expose critical weaknesses during rollout.

Whether Starknet can balance innovation with stability may define its role in Ethereum’s scaling roadmap going forward.
