Arbitrum network suffers minor outage due to hardware failure


The second-level (L2) Arbitrum scaling solution suffers a minor outage. Thus, the project team reported an error in the Sequencer smart contract. Following which the protocol stopped releasing new blocks. Moreover, the developers guaranteed the safety of user funds.

According to the Arbiscan columnist, the last block (#4509808) in the Arbitrum network at the time of writing was at about 10:30 AM +UTC. The protocol does not work for more than five hours.

The Sequencer smart contract has limited authority to manage the order of transactions. Due to this, registration of user transactions occurs immediately, before confirmation from the Ethereum blockchain. The transfer of funds through this contract is optional, network clients can bypass it.

Sequencer cannot steal funds or forge transactions

In September 2021, there was a 45-minute glitch in the work of the Arbitrum. In addition, then the main cause of the incident was the Sequencer bug. Which received a very large package of transactions in a short time.

“Users have the ability to bypass Sequencer and send transactions directly to Ethereum for deferred inclusion in the Arbitrum chain, and this feature was fully preserved during the incident”. The developers explained at that time.

After the incident, the developers said that this contract could not steal funds or forge transactions. Because each operation processed by it has a verified in L2 digital signature of the user. They also warned about possible repeated failures, since Arbitrum One is still in beta testing.

Solana’s decrease in the performance of mainnet’s beta version

On January 6, Solana developers reported a decrease in the performance of the beta version of the mainnet. And warned users about possible errors in transaction processing.

Furthermore, the explanation of a problem was an increase in the number of “high-performance computing operations”. According to the developers, because of this, the network bandwidth dropped “to several thousand” transactions per second (TPS).

The project team stressed that they are working together with ecosystem participants to correct the situation and increase the network’s fault tolerance.
