Jeff Horseman got into journalism because he liked to write and stunk at math. He grew up in Vermont and he honed his interviewing skills as a supermarket cashier by asking Bernie Sanders “Paper or plastic?” After graduating from Syracuse University in 1999, Jeff began his journalistic odyssey at The Watertown Daily Times in upstate New York, where he impressed then-U.S. Senate candidate Hillary Clinton so much she called him “John” at the end of an interview. From there, he went to Annapolis, Maryland, where he covered city, county and state government at The Capital newspaper. Today, Jeff writes about anything and everything. Along the way, Jeff has covered wildfires, a tropical storm, 9/11 and the Dec. 2 terror attack in San Bernardino. If you have a question or story idea about politics or the inner workings of government, please let Jeff know. He’ll do his best to answer, even if it involves a little math.
  • On April 1 between 1:52 AM and 6:02 AM CET, no blocks were generated on the mainnet.
  • The zkSync Era mainnet resumed regular block production after a four-hour outage.

As no blocks were created on the Layer-2 blockchain on Saturday, zkSync Era was unavailable for more than four hours. One of the primary Ethereum Layer-2 scaling options compatible with Ethereum Virtual Machine (EVM) is zkSync Era, which debuted its mainnet on March 24 and is based on zero-knowledge proof roll-up (zk-Rollup).

ZkSync Era Block Explorer shows that on April 1 between 1:52 AM and 6:02 AM CET, no blocks were generated on the mainnet blockchain. Pending zkSync Era transactions have been reported by many individuals who say the blockchain was down.

Back Online After 4 Hours

The problem was not addressed on the official Twitter accounts for zkSync, Matter Labs, or any of the other related companies. The zkSync team later acknowledged the mainnet outage plaguing the zkSync Era and said that they are actively trying to rectify the situation.

The group has requested that users hold off on making any new transactions until the mainnet is back up. The zkSync Era mainnet resumed regular block production after a four-hour outage, as seen by the Block Explorer.

The zkSync Era mainnet alpha was released by Matter Labs on March 24, making it the first zkEVM mainnet to deploy ahead of rivals’ EVM-compatible solution. Polygon’s zkEVM mainnet beta went live on March 27.

ZkSync Era bolsters native account abstraction — enhanced ERC-4337 account abstraction, LLVM compiler, data compression, and Hyperscalability, in addition to facilitating quicker and cheaper transactions.

The zkSync team is still monitoring, auditing, and evaluating vulnerabilities and hazards, thus the era is not yet entirely decentralized. Nevertheless, the Alpha designation will be removed shortly.
