The Ethereum layer-2 protocol Starknet faced a block reorganization issue, causing a transaction backlog and a four-hour outage in block production, as revealed by Starkscan, its block monitoring tool.
On April 4, a gap appeared between the creation of blocks 630028 and 630029, while Starknet’s status page showed no reported outages.
In response, Starknet issued a statement attributing the incident to a rounding error bug, clarifying that although block production continued normally, the reorganization led to a transaction backlog, hindering the network’s full capacity.
The statement explained that for a brief period, new transactions couldn’t be processed and were rejected, and some transactions were reverted due to parameter changes.
Despite attempts to verify details with Starknet, Cointelegraph received no additional information on whether block production ceased during the incident.
The last major outage recorded on Starknet’s status page was on March 13, during Ethereum’s Dencun upgrade, causing slow block creation.

Starknet’s disruption adds to a string of challenges faced by prominent blockchain networks.
Solana, for instance, encountered a significant outage in early February 2024, halting block progression on its mainnet for over five hours.
This was not an isolated incident, as Solana experienced multiple outages since January 2022, including a notable one on February 9, detailed in a postmortem report by Anza, a Solana-focused software development firm.
According to Austin Federa, head of strategy at the Solana Foundation, the recent outage was attributed to a bug in Solana’s Just-in-Time (JIT) compilation cache, which unexpectedly triggered an infinite loop due to an old instruction set.
Solana faced further issues in early April, with approximately 75% of transactions failing amid heightened activity related to memecoin speculation.
Analysts attribute these failures mainly to bot activities seeking arbitrage opportunities on the Solana network.
