Starknet Shuts Down Again, Technical Glitches Threaten Network Reputation

The Starknet network, which operates as a Layer-2 scaling solution for Ethereum ETH $2,720.67 , experienced an outage on January 5.

The disruption left the main network offline while engineers worked to identify the cause.

The downtime, which lasted just over two hours, required technical teams to find solutions and restore normal operations.

Starknet uses zero-knowledge proofs to process transactions independently of the main Ethereum chain. Its technology supports decentralized applications across areas such as smart contracts, decentralized finance (DeFi), and online games, and has integrated Bitcoin BTC $82,372.25 -focused services through its BTCFi system.

An update posted on X by the Starknet team stated that full operations would be restored as soon as possible, but the underlying technical fault remained unspecified at the time of the announcement.

In September 2025, the Grinta (v0.14.0) update led to extended outages, which stopped block production and caused the network to "reorganize", which reversed about one hour of transactions and led to resubmission of activities.

That incident was linked to failures in communication tools used with Ethereum and specific technical bugs in the transaction sequencing process. Multiple downtimes in 2025, including sequencer-based errors, raised questions about Starknet's ongoing reliability.

Meanwhile, Alex Smirnov, founder of deBridge, recently called on validators on the Flow FLOW $0.0570 network to stop confirming transactions. Why? Read the full story.
