Build ROFL App

ROFL diagram

Runtime OFf-chain Logic (ROFL) apps are a mechanism to augment the deterministic on-chain backend with verifiable off-chain applications. These applications are stateless (with support for encrypted persistent local volumes), have access to the network and can perform expensive and/or non-deterministic computation.

ROFL apps run in Trusted Execution Environments (TEEs), similar to the on-chain confidential runtimes. This enables them to securely authenticate to the on-chain backend which is handled transparently by the framework. Together they allow one to implement secure decentralized oracles, bridges, AI agents and more.

The following chapters will teach you how to build your own ROFL app with the help of the Oasis Runtime SDK.
