Blockchain Network Stability Takes Another Hit After Starknet’s Block Reorganization, Resulting in a Transaction Backlog

The statement clarified that certain transactions were reverted as a result of parameter modifications, and that new transactions were denied and couldn’t be executed for a short while.

According to Starkscan, its block monitoring tool, the Ethereum layer-2 protocol Starknet encountered a block reorganization issue that resulted in a transaction backlog and a four-hour disruption in block production.

There was a pause on April 4 between the generation of blocks 630028 and 630029, although there were no known disruptions according to Starknet’s status page.

Starknet responded by releasing a statement blaming the event on a rounding error flaw. The statement made clear that while block generation carried on as usual, the reorganization created a transaction backlog that prevented the network from operating at its maximum capacity.

The statement clarified that certain transactions were reverted as a result of parameter modifications, and that new transactions were denied and couldn’t be executed for a short while.

The most recent significant disruption noted on Starknet’s status page occurred on March 13th, within Ethereum’s Dencun update, resulting in sluggish block generation.

The disruption caused by Starknet is just one more issue that well-known blockchain networks are dealing with.

For example, Solana experienced a major failure in early February 2024 that prevented block progression on its mainnet for more than five hours.

This was not an isolated issue; since January 2022, Solana has had several outages, the most significant of which occurred on February 9 and was documented in a postmortem report by Anza, a software development company that specializes in Solana.

Austin Federa, head of strategy at the Solana Foundation, claims that an old instruction set in Solana’s Just-in-Time (JIT) compilation cache caused a flaw that caused an unexpected endless loop, which is what caused the recent outage.

In early April, Solana had more problems, with over 75% of transactions failing amidst increased traffic associated with memecoin speculation.

Analysts primarily blame bot activity on the Solana network for these failures, as it searches for arbitrage possibilities.
