Monad is not a rollup because we believe that decentralized block production is a first-class priority

[serrq]

“Monad is a new layer-1 blockchain, and a common question that we get is: “why not implement Monad as a rollup?” There are a few major reasons:

The first reason is decentralization. Rollups currently lack a mechanism for decentralized block production, which is essential to censorship-resistance and true decentralization.

The second reason is performance. We’re building the most performant and least expensive system possible, and building as a rollup would impose limitations to Monad’s scalability.

The last reason is focus. We believe that a high-performance EVM execution environment, runnable by anyone, is on the critical path to massively improving the reach and utility of decentralized computation.”
