L2S NEED A NEW ROLE

Summary from the TLDR Crypto newsletter

Vitalik Buterin says the original rollup-as-branded-shard roadmap no longer fits. The Ethereum layer 1 is scaling, and many layer 2s (L2s) won't or can't be true shards, so L2s should pick clear non-scaling value adds, be at least stage-1 when handling ETH, and maximize interoperability. Furthermore, Ethereum should add a native rollup precompile for ZK-EVM proof verification to enable safe, trustless L1 to L2 (and vice versa) interop and synchronous composability.
