"Rollups are in the short and medium term, and possibly the long term, the only trustless scaling solution for Ethereum. Transaction fees on L1 have been very high for months and there is greater urgency in doing anything required to help facilitate an ecosystem-wide move to rollups. Rollups are already significantly reducing fees for many Ethereum users: [l2fees.info](http://l2fees.info)  frequently shows Optimism and Arbitrum providing fees that are ~3-8x lower than the Ethereum base layer itself, and ZK rollups, which have better data compression and can avoid including signatures, have fees ~40-100x lower than the base layer.”
