zkSync Era suffers 4-hour outage due to server bug

Era on Ethereum layer 2 network zkSync suffered a temporary block production outage today, but is now fully operational due to a bug-related outage that lasted more than four hours.

In X’s December 25 post, the developer confirmed that a bug within the server triggered automated safety protocols, causing network issues.

“The zkSync Era network is now fully operational. At 05:50 UTC, a bug in the server tripped one of the network’s automated safety protocols. “This issue had to be investigated by the team and is now fully resolved,” the team said.

The layer 2 network developer, backed by Matter Labs, promised to share an after-action report soon.

but, CryptoSlate’s test According to information on zkSync’s Era website via website monitoring platform Uptime, an outage occurred in the sequencer at Layer 2 at approximately 6:56 AM CET on December 25, with service being suspended at 10:56 AM CET. has been restored.

Sequencers play an important role in layer 2 networks by verifying, organizing, and compressing transactions for transmission to layer 1 chains, such as Ethereum.

Blockchain security audit firm ChainLight discovered a vulnerability in the protocol last month. This bug allows malicious actors to manipulate transactions within a block and ensure they are still accurate. If exploited, this vulnerability could drain 100,000 Ethereum from the protocol.

According to L2beat data, zkSync’s Era has achieved significant growth since launch and ranks as one of the top five Layer 2 networks in terms of total asset value. As of press time, approximately $570 million in digital assets are locked in the protocol.
