Abstract
Harmonia proposes an open decentralized workflow engine for Canton that lets teams define and compose workflow-heavy multi-party applications without relying on a central workflow operator. It delivers a bounded workflow-definition DSL, a reusable runtime and composition framework, example workflows, and developer documentation to reduce the cost and implementation risk of building composable Canton applications.
