Offchain Labs says Arbitrum wasn't down for an hour, despite transaction issues
Offchain Labs, the team behind the Arbitrum Layer 2 project, says the network was not down for an hour yesterday. "Was Arbitrum One down for an hour? No," CTO Harry Kalodner said Friday on social media. "Did the batch poster stop posting for an hour? Yes." Many users had presumed Arbitrum was down for an hour because the Ethereum Layer 2 network didn't seem to be processing transactions. However, Kalodner explained that the outage was due to the batch poster.
"The batch poster hit an edge case in geth's mempool implementation which caused it to reject transactions if the total cost of all transactions in the mempool was greater than the balance of the sender," he continued. "This blocked the batch poster from escalating the fees of any transaction. This is made particularly complex since the Arbitrum One batch poster's main ETH balance is stored in a separate smart contract called the gas refunder which reimburses it for ETH spent on batch posting to increase security of its funds.". The batch poster consumes about 2% of Ethereum's gas limit and the gas refunder is unusual. It's no wonder it hits weird edge cases."
