Starknet Reports on Network Outage, Promises Improved Stability

On March 25, 2025, Starknet, an Ethereum layer-2 scaling network, experienced a temporary outage that required a significant rollback of network activity. This incident marked the second major disruption for the network in 2025, as both occurrences necessitated a block reorganization to restore functionality.

In a detailed post-mortem report released on March 26, Starknet’s team identified a discrepancy between the blockifier execution layer and the proving layer, which is responsible for ensuring that transactions are processed accurately. According to the report, “In one specific combination of cross-function calls, variable writes, reverts, and catching them, the blockifier remembered a state-writing that happened within a function that was reverted, causing an incorrect transaction execution.” Fortunately, the proving layer effectively flagged this error, preventing the faulty transactions from reaching Level 1 finality.

The incident resulted in the reversion of 18 minutes of network activity, forcing users to resubmit their transactions. While this may be a minor inconvenience for some, it can pose significant challenges for frequent traders or investors who require timely execution of their trades.

Starknet’s operational team expressed their commitment to enhancing network stability through improved testing and code audits to prevent similar issues in the future. The March 2025 outage added to the challenges faced by the network, which had previously encountered a more serious disruption in September 2025 during a major protocol upgrade known as Grinta. That incident halted block production entirely, leading to two chain reorganizations that rolled back approximately one hour of network activity.

As the cryptocurrency landscape continues to evolve, addressing such technical challenges remains crucial for the credibility and reliability of blockchain networks. Starknet’s proactive measures and transparency regarding these incidents reflect its commitment to a more robust and user-friendly platform.

The ongoing developments within the crypto industry underscore the importance of network resilience and the need for continuous improvement. With Starknet back to normal functionality, the team remains focused on ensuring that users can navigate the platform with confidence, free from the disruptions that can impact trading activities and investor trust.
