Arbitrum Network Stalled Due to Sequencer Downtime


The Arbitrum community, an Ethereum L2 (Layer 2) rollup, skilled some difficulties that brought on an entire cease within the manufacturing of blocks and the affirmation of transactions. According to studies from the Arbitrum staff, this incident needed to do with downtime concerning its sequencer, a particular node that manages the order of transactions, leaving the community unusable for about seven hours.

Arbitrum Stalls for 7 Hours

The community of Arbitrum, an optimistic scaling rollup for the Ethereum community, stopped fully on January 9, leaving customers unable to make transactions for about seven hours. The Arbitrum staff knowledgeable customers that the difficulties have been brought on by points with their major sequencer node, which skilled a {hardware} failure that led to the community stall. According to Arbitrum docs, the sequencer is a “specifically designated full node, which is given restricted energy to manage the ordering of transactions.”

The Twitter account of the rollup reported the problem first, clarifying they have been experiencing sequencer downtime and stating that each one the funds have been secure.

In a submit mortem submit, Offchain Labs explained that there have been different conditions that additionally contributed to the state of affairs that the rollup confronted, noting:

While we typically have redundancies that might enable a backup Sequencer to seamlessly take management, these additionally did not take impact this morning as a consequence of a software program improve in course of. As a consequence, the Sequencer stopped processing new transactions.

Problems in Rollup Land

This isn’t the primary time that Arbitrum has confronted issues concerning the operation of its community. The service confronted the identical type of concern again in September when the Sequencer failed that point as properly. This brought on the community to change into non-operational for 45 minutes. At the time, Offchain Labs stated:

The root reason behind the downtime was a bug inflicting the Sequencer to get caught when it obtained a really massive burst of transactions in a brief time period. The concern has been recognized and a repair has been deployed.

While Ethereum has centered on scaling utilizing one of these resolution, the proposal has nonetheless not been properly obtained by some customers. According to Delphi Digital, these L2 options are “shedding market share to L1’s in current months, regardless of the migration of DeFi protocols from Ethereum.”

Even so, Arbitrum is the primary rollup resolution within the Ethereum ecosystem by way of complete worth locked (TVL), having launched on mainnet final August. The resolution has over $2.62 billion in complete worth locked, based on data from L2beat, an Ethereum L2 statistics service.
