Ethereum Foundation Co-Executive Director Tomasz K. Stańczak advocates reducing L1 complexity and mainly relying on L2 scaling; Vitalik Buterin responds that the key is accessibility rather than safety trade-offs, and points out that if large-scale execution expansion and limited state expansion are implemented, applications might shift to maintaining a "virtual state" using Merkle proofs. However, this would increase off-chain dependencies and risks. Vitalik believes that it is preferable for L1 to do a moderate amount of work to reduce application layer complexity, and there is no need to rush to a final solution at this stage.
