Core features of altlayers in house rollup stack

Modular

The entire AltLayer stack is built with modularity in mind making it possible to end users to pick and choose for their rollups: a preferred run-time (such as EVM, WASM and others), a data availability layer (such as the underling L1 or data availability committee, Celestia, etc), a settlement layer (such as Ethereum, Arbitrum One).

Persistent Rollups

Persistent rollups offered by AltLayer are standard optimistic rollups except that they application-specific and both EVM & WASM compatible.
