Ethereum layer 2 scaling protocol Arbitrum went down for 45 minutes due to the Sequencer bug.
On September 14, the Arbitrum One protocol experienced its first major issue with a 45-minute blackout that blocked transactions from being processed for the period. Arbitrum One protocol was launched at the beginning of this month.
Arbitrum One protocol said,
“The root cause of the downtime was a bug causing the Sequencer to get stuck when it received a very large burst of transactions in a short period of time. The issue has been identified and a fix has been deployed.”
According to Offchain Labs, the firm behind the technology, the funds were not at risk, and that it’s still in a beta phase. In addition, the team warned that there may be more glitches and interruptions to come.
The company noted,
“But, as we noted in our launch announcement, we do want to caution users that further outages are possible in these early days.”
In addition, Offchain Labs emphasized that a bug in the Sequencer caused transactions to be reassigned to a timestamp. But maintaining their system.
Based on reports, the Sequencer lets users post transactions directly on-chain, giving an instant response.
What is more, reports say that Sequencer can steal funds or forge transactions. Specifically, every transaction it manages is digitally signed by a user. Moreover, the Arbitrum chain checks the signatures before explaining.
