Ethereum Layer 2 “zkSync Era” temporarily stops generating blocks due to network failure

Block generation stopped due to temporary failure

It was revealed that the L2 network “zkSync Era” of the virtual currency Ethereum (ETH) stopped generating blocks for about two hours yesterday afternoon.

According to zkSync official X, at around 14:50 Japan time, one of the network’s automatic safety protocols was triggered by a server bug, which has now been completely resolved. It also said that the cause of the accident “needs to be inspected by a team.” zkSync Era network operations have already been restored.

The zkSync Era network is now fully operational. At 05:50 UTC, one of the network’s automated safety protocols was triggered by a bug in the server. This issue required teams to inspect and is now fully resolved.

We will share a full post-mortem report soon. Thank you for your…

This wasn’t zkSync Era’s first network outage. A temporary network outage also occurred on December 16th. At the time, on-chain activity called “inscriptions” was rapidly increasing and appeared to be destabilizing the network.

zkSync Era is an L2 solution classified as “zkEVM” that is compatible with Ethereum’s virtual machine (EVM), and its main feature is that it uses “ZK Rollup”, a rollup technology that introduces zero-knowledge proofs. is.

The network released its alpha version in March of this year and currently ranks 4th in TVL among all L2 rollups with approximately $160 million.

Arbitrum also went offline last week

Recently, there have been many cases where the Ethereum L2 network goes offline or block generation stops.

On the 15th of last week, Arbitrum’s sequencer (validator-like function) stopped working for about an hour and a half, and it was only able to process two transactions in each block, causing gas fees to skyrocket and at one point costing $100. There were times when it was exceeded.
