Ethereum layer-2 community zkSync’s Period confronted a brief block manufacturing halt as we speak however is now again in full operation following a bug-related disruption that lasted over 4 hours.
In a Dec. 25 put up on X, the builders confirmed {that a} bug inside its server triggered an automatic security protocol, inflicting community points.
“The zkSync Period community is now absolutely operational. At 05:50 UTC, one of many community’s automated security protocols was triggered by a bug within the server. This situation required groups to examine and is now absolutely resolved,” the workforce said.
The Matter Labs-backed layer-2 community builders promised to share a autopsy report quickly.
Nonetheless, CryptoSlate’s examination of the zkSync’s Period web site by way of Uptime, a web site monitoring platform, indicated that an outage occurred on the layer-2’s Sequencer round 6:56 am CET on Dec. 25 and providers had been restored by 10:56 am CET.
The Sequencer performs an essential function in layer-2 networks by verifying, organizing, and compacting transactions for switch to layer-1 chains resembling Ethereum.
ChainLight, a blockchain safety audit firm, discovered a vulnerability within the protocol final month. The bug would enable a malicious actor to control transactions inside a block and nonetheless have them verified as correct. If exploited, the vulnerability might have drained 100,000 Ethereum from the protocol.
Since its launch, zkSync’s Period has skilled substantial development, rating among the many high 5 layer-2 networks by way of whole worth of property, in response to L2beat data. Round $570 million in digital property are locked on the protocol as of press time.
Notably, the protocol just lately built-in Chainlink’s value feeds by way of its inclusion within the Oracle blockchain’s SCALE (Sustainable Chainlink Entry for Layer-1 and a pair of Enablement).
The put up zkSync Period sees 4-hour outage as a consequence of server bug appeared first on CryptoSlate.
