Ethereum Layer 2 Starknet has announced the launch of “appchains,” a framework that allows developers to create several application-specific blockchains within its ecosystem. 

This step is consistent with the broader evolution of the Layer 2 ecosystem, where projects such as Polygon, Arbitrum and Optimism have already set the stage for similar modular networks. Starknet is the latest addition to this lineup.

Developers can create appchains using Starknet Stack, the ecosystem’s native developer tooling. These chains will utilize STARK proofs for enhanced security. Central to this stack is Cairo, a programming language developed by the StarkWare team, which shares similarities with Rust.

In a blog post, the team suggested that by leveraging Starknet appchains, developers can …
