While we mostly person redundancies that would let a backup Sequencer to seamlessly instrumentality control, these besides failed to instrumentality effect this greeting owed to a bundle upgrade successful process. As a result, the Sequencer stopped processing caller transactions.

Problems successful Rollup Land

This is not the archetypal clip that Arbitrum has faced problems regarding the cognition of its network. The work faced the aforesaid benignant of contented backmost successful September erstwhile the Sequencer failed that clip arsenic well. This caused the web to go non-operational for 45 minutes. At the time, Offchain Labs stated:

The basal origin of the downtime was a bug causing the Sequencer to get stuck erstwhile it received a precise ample burst of transactions successful a abbreviated play of time. The contented has been identified and a hole has been deployed.

While Ethereum has focused connected scaling utilizing this benignant of solution, the connection has inactive not been good received by immoderate users. According to Delphi Digital, these L2 solutions are “losing marketplace stock to L1’s successful caller months, contempt the migration of DeFi protocols from Ethereum.”

Even so, Arbitrum is the fig 1 rollup solution successful the Ethereum ecosystem successful presumption of full worth locked (TVL), having launched connected mainnet past August. The solution has implicit $2.62 cardinal successful full worth locked, according to data from L2beat, an Ethereum L2 statistic service.
