Solana and Arbitrum knocked offline while Ethereum evades attack

After suffering a denial of service disruption, Solana (SOL), a rising Ethereum competitor, has lost 15% of its value in the last 24 hours.

Twitter account Solana Status reported that Solana’s mainnet beta was experiencing intermittent instability for 45 minutes.

Six hours after the announcement, Solana Status stated that the incident was caused by a significant increase in transaction loads to 400,000 per minute. This created a denial of service and caused the network’s forking to begin.

1/ Solana Mainnet beta experienced a significant increase in transaction loads, which reached 400,000 TPS. These transactions overwhelmed the transaction processing queue and network-critical messaging was not prioritized. The network began forking.

Solana’s engineers were unable to stabilize their network so the validator community decided to coordinate a restart. The Solana community is currently working on a new release. More information will be available soon.

Prices fell by 15% within 12 hours due to the incident. SOL traded below $175 on Sept. 9, but had already fallen to $215 at its high of $215 on Sept. 9. However, prices quickly fell to $145 after the news about the outage.

Solana isn’t the only prominent crypto network that went down on September 14, as Arbitrum One, an Ethereum layer-two rollup network reported its sequencer was offline for approximately 45 minutes.

Arbitrum One stressed that user funds were “never at risk”, but new transactions couldn’t be submitted during this period. Offchain Labs, which is responsible for building Arbitrum One, warned that further outages could occur in the early days.

After submitting a large number of transactions to the Arbitrum sequencer in a short time, the team attributes the downtime as a bug that caused the sequencer’s to become stuck.

As if all that was not enough drama, an unknown entity attempted to attack Ethereum. Marius Van Der Wijden, a developer, flagged the incident on Twitter.

The developer claims that only a few Nethermind nodes were tricked to switch to the invalid chain. All other clients had “rejected long sidechains as invalid” and all affected nodes have since been reorganized to the correct chain.
