ABCI-Compatible Execution Layers in Rollkit

Rollkit is designed to be modular and flexible, allowing different execution layers to be plugged in via the ABCI (Application Blockchain Interface) protocol. Rollkit defines a general-purpose execution interface (see execution.go) that enables developers to integrate any ABCI-compatible application as the rollup's execution layer.

This means you can use a variety of ABCI-compatible applications as the execution environment for your rollup.

Supported Execution Layers

Cosmos SDK App

A Cosmos SDK-based application can serve as the execution layer for a Rollkit rollup. This allows you to leverage the rich ecosystem and features of the Cosmos SDK, including modules for staking, governance, IBC, and more.

• Cosmos SDK Documentation

CosmWasm

CosmWasm is a smart contract platform built for the Cosmos ecosystem. It is ABCI-compatible and can be integrated as the execution layer in Rollkit, enabling your rollup to support WebAssembly (Wasm) smart contracts.

How It Works

• Rollkit acts as the consensus and data availability layer.
• The execution layer (Cosmos SDK app or CosmWasm) processes transactions and maintains application state.
• Communication between Rollkit and the execution layer happens via the ABCI protocol.

Benefits

• Modularity: Choose the execution environment that best fits your use case.
• Interoperability: Leverage existing Cosmos SDK modules or deploy CosmWasm smart contracts.
• Extensibility: Easily upgrade or swap out the execution layer as your rollup evolves.
